Summary of My Post-CPI Tweets (June 2019)

Below is a summary of my post-CPI tweets. You can (and should!) follow me @inflation_guy. Or, sign up for email updates to my occasional articles here. Investors with interests in this area be sure to stop by Enduring Investments or Enduring Intellectual Properties. Plus…buy my book about money and inflation. The title of the book is What’s Wrong with Money? The Biggest Bubble of All; order from Amazon here.

  • OK, CPI day at last. We get to find out if Powell meant “transitory” in the one-month sense (probably not) or in the 3-6 month sense (more likely).
  • After all we have had three weak core CPI figures in a row: 0.110% for Feb, 0.148% in March, 0.138% in April. Three 0.1%s, rounded.
  • Last month the culprit was used cars, -1.3% m/m, and Apparel at -0.8% m/m, the latter due to a methodology change. These are both short-term transitory, probably.
  • Meanwhile, the evidence that core is being infected these last three months by tail events is in the median CPI, which was +0.26%, +0.27%, and +0.20% the last 3 months.
  • Housing, on the other hand, remains strong, and this should continue for a bit; Medical Care remains weak with pharma especially (+0.1% y/y)…and I think that is “longer-term transitory” that should start to retrace higher.
  • I am expecting a return to normalcy, not so much a rebound, in autos and apparel. But that should be enough to hit the consensus figures of 0.21% on core, 2.09% y/y.
  • Longer-term, the fact that interest rates have fallen so far suggests that the small rebound we have seen over the last year and a half in money velocity may have trouble extending.
  • So I think Median probably peaks late this year or early next, though I don’t expect it to fall off a cliff, either, in this recession.
  • Grabbing coffee. Back in 11 minutes.
  • So maybe a liiiiiittle more transitory than we thought! Core +0.11% m/m, +2.00% y/y.
  • Last 12 months. The comp is easier next month, but none of the last 4 months would have exceeded it anyway!

  • Apparel basically flat m/m, which is approximately what I expected…-3.06% y/y though, which includes the methodology change.
  • CPI-Used Cars and Trucks was again down sharply m/m. -1.38%. That’s unlikely. Pushes y/y to +0.28%, Black Book has it about 1% above that.

  • Housing: OER +0.26% m/m, Primary Rents +0.24%. Actually those aren’t far from the trends (y/y in each case declined a couple of hundredths, to 3.34% and 3.73% respectively), but last month had been chippier.
  • Medical Care (and then I’m going to take a few minutes and dig deeper on some of these)…Medicinal Drugs (pharma) went into deflation. -0.11% m/m, -0.82% y/y. Chart in a moment. Doctor’s Services roughly unch, but only 0.30% y/y. Hospital Services bounced a bit, 1.30% y/y.
  • Even with the bounce, Hospital Services is lower than two months ago, 3 months ago, etc. One year ago it was 4.70% y/y. Hospital Services is the largest component of the Medical Care subindex.
  • Here is the y/y chart for drugs. Now, it’s very hard to measure this because there is tremendous dispersion in consumer costs for prescription drugs…massive differences based on which outlet, formulary, insurance, etc you have. Doing a lot of work on this. Sooo…

  • this is the y/y picture for NONprescription drugs, which are much easier to measure. Basically no chg. So either prescriptn drug mkt is getting much more competitive (I doubt it), there is some change in collection method (possible), or a shift showing up as change.

  • there is no lower-level index for drugs so we can’t really dig any deeper on that unfortunately. But it’s significant, not only for the CPI of course but for consumers generally (and the budget deficit) if health care costs really ARE slowing in a permanent way.
  • CPI – College Tuition and Fees, essentially unch at 3.81% vs 3.86% y/y. But well off the lows.

  • Now what does that last picture look like…oh, yeah, the S&P Target Tuition Inflation Index (my baby).

  • Core inflation ex-housing down to 1.04%, the lowest level since February 2018. Still nowhere near the lows, nowhere near deflation, and with lots of transitory stuff in it.

  • Core goods prices still in deflation, -0.2%. But lagged effect of the dollar’s 2017 selloff should just now be starting to wash into the core goods data. And we still haven’t seen the tariff effect yet. So this is still to come and the reason I don’t think we’ve peaked yet.

  • WEIRD: Biggest declines on the month were used cars & trucks (-15.3% annualized), Leased cars & trucks (-13.8%). Biggest gainers: Car and Truck Rental (+26.5%), Public Transportation (+24.8%).
  • Early estimate for Median CPI is +0.21% m/m, making y/y 2.81%. So, again, it’s a tails story.
  • Sorry, didn’t calculate the sheet for y/y. Should be 2.76% y/y for median, down from 2.80%.
  • Here is m/m Median CPI. Notice there’s really no major slowdown here. It’s been pretty steady and rising slightly y/y for a while. Nothing below 0.2% m/m since last August.

  • OK, four pieces and then we’ll sum up. Piece 1 is food and energy.

  • Piece 2 is core goods. As I said, I expect this to turn back higher. This is where you find Used Cars and Apparel…so transitory stuff is big here. This is also where tariffs fall heaviest.

  • Piece 3 is Core Services less Rent of Shelter. Same story here: “What is up with medical care?” It may be that since consumers under the ACA end up paying out of pocket for a much larger share, they’re bargaining harder. That could be why it feels so much worse than this.

  • Finally, rent of shelter – same old same old. No deflation while this remains steady as a rock.

  • So, in sum. I do think that Powell is right in focusing on the “transitory” inflation slowdown. Better measures, such as Median (see below for Median vs core), show no significant slowdown yet.

  • …and it’s hard to see where a slowdown would come from. Medical Care is already very slow. Core goods is already very slow, with negative tails already in the data but not much sign yet of the tariff effect sure to come. Housing is solid.
  • So for now, I expect median inflation to continue to crawl higher. As we get later in the year, though, unless interest rates rebound a lot higher there’s a decent chance that money velocity droops again.
  • Now, money velocity is already REALLY low so it may not. This chart isn’t our best model but it suggests velocity is already too low for the level of int rates (I’m not sure it’s a linear function near zero though). It was responding, but lower int rates may truncate a bounce.

Nothing more really to add – I will say that although Powell is right and these are transitory factors, I have lost faith that the Chairman is a “different sort” of Fed Chair since he doesn’t have an academic background. He was at first, but appears to have been captured by the econocognoscenti. Ergo, I expect the Fed will ignore the fact that inflation is still drifting higher, and start to cut rates as the growth figures make it ever clearer that the economy is heading towards (if not already in) recession. Long-end yields are already 110bps or more off the highs, so I think the bond market already has more than half its recession-rally finished (I don’t think we’ll have new low yields this cycle since I don’t think inflation will collapse and I don’t think the recession will be as bad). But stocks haven’t even begun their earnings-recession selloff, so…

What “Transitory Factors” Might Tell Us About Inflation

May 23, 2019 2 comments

There is a lot of buzz around inflation these days. Some people are explaining why we shouldn‘t worry and some people why we should, but regardless – it’s a topic of conversation for the first time in ages. And despite this (or rather, because of it, because I find myself very busy these days), I haven’t written in a long time despite the fact that I have a few things worth writing about. I keep trying, though.

Today I am cheating a bit and taking a column from the quarterly inflation outlook that my company (Enduring Investments) just sent to customers. But I think it is fair to include it here, because the musing was provoked by a recent exchange I had on Twitter while doing my monthly CPI analysis/tweetstorm (follow me @inflation_guy).

As readers know, I tend to focus on Median CPI, rather than Core CPI, as my forecast target variable. The reason is that price changes are rarely distributed randomly. If they were, then the choice of core or median CPI would be irrelevant because they would normally be the same, or roughly the same. But when a distribution has long tails, the ends of the distribution exert a lot of pressure on the average and so median can differ substantially from the mean simply because one tail is much longer than the other even if most of the distribution is similar.

Consider a playground see-saw and imagine that on one side of the see-saw are seated several small children. Think of the “average” of the see-saw system as the point where the see-saw balances. Well, there are lots of ways to balance the system with weight on the other side of the see-saw: a very large weight close to the fulcrum will do it. But the further away from the fulcrum one places the weight, the smaller the weight necessary to balance the scale. As Archimedes said, “give me a lever long enough, and a place to stand, and I can move the world.” The point is that an influence far from the middle of the distribution can have a very significant effect on the average because it is far away from the distribution:  the effect on the mean is (weight * distance from the mean).

Example: the mean of 98% of a distribution is 12. The remaining 2% of the distribution is 28. The weighted average is [(12 * 0.98) + (118 * .02)] / (0.98 + 0.02) = 14.12.  That little 2% caused the mean to go from 12, without the tail, to 14.12 with the tail…a movement of 17.7%! Notice that .02 * 118 = 2.12, which is the amount the mean moved. And if that tail is 228 rather than 118, the mean goes to 16.32. So you see, the length of the tail matters. In both cases, the median was 12, which I would argue is a better indicator of the “central tendency” of the distribution.

(If the distribution is approximately normal, then the tails roughly balance and so the mean and median are about the same. But many economic indicators are not normally distributed, especially ones like income or home prices which are bound by zero on one side. Thus, for many economic series the median, rather than mean, is a better measure. Even though CPI is not bound by zero, it is not normal because prices are not set in a continuous process but instead to have jump-discontinuities.)

The chart below, which I often show in my CPI tweetstorm, shows the see-saw of CPI, where I’ve broken up the index into its lowest-level components and placed those weights on a number line representing the most-recent year-over-year changes. The height of the bar indicates the amount of the basket that sits in that bucket. As you can see, nearly half of the CPI is inflating faster than 3% (which is why Median CPI is 2.8%), and the mode of the distribution is between 3.5% and 4.0%. But because of the far left tail, the mean – which is what core CPI is – is just barely over 2%. Because we have much longer left-hand tails than right-hand tails, the average is biased lower relative to median.

But is this “normal?” Some people have occasionally accused me of picking Median CPI because it tends to be higher, and so the number makes it look like there is more inflation. If the spread were constant, then it would be a bit academic which we chose as the forecast variable, and in fact Core would have a better claim since after all, as consumers purchasing that basket we are in fact paying the average price and not the median.

In fact, though, I think that the tendency of core in recent years to trade below median really is its own interesting story about how prices evolve. If we have 3% inflation, it does not mean that all prices are going up at 3% per year, 0.75% per quarter, 0.25% per month. The price of any given good doesn’t move smoothly but rather episodically, sporadically, spastically. When we are in a disinflationary period, or anyway a low-inflation period, what is happening is that those episodes involve periods of slower prices and “transitory factors” that tend to be on the downside.[1] In that sense, it may be that the Fed, and me/Enduring, both err when they try to look through ‘transitory factors’ because transitory factors may be part of the process. The argument for that perspective is similar to the argument I myself make about why “ex-items” measures make sense when you are looking at an individual company’s earnings but not when you look at the aggregate earnings of the economy. Because bad stuff, or “items,” are always happening to someone somewhere. You can throw them out of any one analysis but if you own the index, you’ll get some of those “items.” You just don’t know from where. Perhaps inflation is the same way.

However, I should point out that median inflation is not always below core. The chart below shows median and core CPI going back to 1983, which is when the Cleveland Fed’s series for Median CPI begins. Notice that from 1983 until 1993, Median CPI was generally lower than core CPI. In 1994, this changed and it has been the opposite ever since.

The year 1994 is significant because that is also the year that most models for inflation that are calibrated on pre-1994 data break down (or, conversely, it is the year prior to which a model calibrated on post-1994 data breaks down). I have written previously about this phenomenon and the fact that the Fed believes this is when inflation expectations abruptly became “anchored,” whatever that means – but *I* believe that this discontinuity is when globalization kicked into high gear with an explosion in the number of bilateral and multilateral trade agreements. It strikes me as plausible that these items are related. When markets are suddenly opened to global competition, affected markets will suddenly show slower price appreciation due to the pressure from that competition (and the replacement of high-cost domestic goods with lower-cost imports). But which market is currently being affected will not stay constant, but change over time. In other words, I think the fact that core has been persistently below median for a long time is a symptom of the globalization “dividend.”

If I am right, and if if I am also right about the arrow of globalization changing direction, then it follows that core and median might flip positions at some point over the next couple of years. And then the “transitory effects” will be mostly on the high side.


[1] It could also be indicative of a bias from the measurers that their improved methods are always looking for lower inflation – not in the “the BLS is making up this *@&$^” sense but in the sense that for lots of reasons the CPI appears to be overstated because of technical details about the functional form, the way measurement errors happen, etc. And so researchers may spend more time looking for ways that inflation is overstated. I don’t think that research bias is actually much of a problem. But I figured I ought to mention that that is one possible interpretation.

Summary of My Post-CPI Tweets (May 2019)

Below is a summary of my post-CPI tweets. You can (and should!) follow me @inflation_guy. Or, sign up for email updates to my occasional articles here. Investors with interests in this area be sure to stop by Enduring Investments or Enduring Intellectual Properties. Plus…buy my book about money and inflation.

  • Happy(?) tariff day! With new tariffs imposed overnight, important to remember that the IMPORTANT effect on prices is not the near-term bump (which is small), but the fact that the disinflation of last 25y was possible because of trade liberalization.
  • Also of course happy CPI day. We get the number in a few minutes. Here are a few pre-thoughts.
  • Last month, core CPI was +0.148% m/m and 2.042% y/y, which both rounded down and looked like big misses.
  • They weren’t really big misses, and at least some of that was due to a plunge in Apparel prices that was probably methodology-related (at least, that’s what the econs had anticipated so let’s take as an initial guess that they were right).
  • Rents, the biggest and most important (and slow-moving) piece, were firm – firmer than I’ve been expecting in fact.
  • But used cars was weak, along with Doctor’s services…along with Apparel, in general there was a lot of “left-tail stuff.”
  • The left-tail nature of last month’s figure was illustrated by the fact that MEDIAN, the measure I focus on, was +0.27% to 2.85% y/y…another post-crisis high.
  • Today, the consensus is for 0.2%/2.1% on core inflation. We would have to get something below 0.12% m/m to keep core from bumping to 2.1%, and any kind of firm number (>0.21%) could pop us back to a rounded 2.2%.
  • That’s because last April was pretty weak. In fact four of the next 5 months were under 0.2% a year ago, so the comps will be easier for core.
  • Core CPI +0.14%, slightly weaker than expected but rounding down to 0.1% again. Y/Y was 2.07%, so it did round up.
  • Soft-looking but as noted earlier, base effects made it hard to maintain a 2.0% on core.
  • Last 12 m/m core cpis.

  • OK, the number is stronger than it looks. Used Cars very weak, -1.31% m/m which is crazy. Doesn’t look anything like the private surveys. Apparel -0.76% m/m again, -2.9% y/y. That’s not an accurate depiction of what’s happening.
  • Because mainly of those two pieces, core goods went to -0.2% from flat. With tariffs rising, that doesn’t pass the sniff test. Core services, though, rose to 2.8% y/y. Primary rents were +0.45% m/m, 3.76% y/y, and OER +0.33%.
  • Rent of primary residence. This is surprising, but important.

  • Here is OER. With the Shiller index softening, many had expected rents to follow. But chippy wages are helping to keep a bid here, for now at least.

  • There’s a real problem using home price indicators to forecast rents, because your model for that was built over a qtr-century in which wages & inflation were low and stable. If wages rise, then maybe home prices will lag rents – but we don’t know because we haven’t seen it.
  • OK on to other things. Medical Care rose to 1.92% y/y vs 1.72% last mo. Every month it’s something different m/m tho. It was Pharma. Then Doctors’ Services last month. This month Dr Svcs bounced a little but Hospital Svcs -0.46% m/m. And Hosp Svcs is lgst part of Med Care.
  • Core ex-housing was unchanged at 1.1% y/y. That’s actually surprising considering the drag from apparel and used cars.
  • I may have been wrong on Used Cars being very surprising though. Guess there must be some uncaptured seasonal issue because y/y actually rose (meaning last April was also awful). And this is right on model. So I retract my concern about Used Cars.

  • Biggest category drops on the month: Men’s and Boy’s Apparel (again), Footwear, Processed Fruits and Veggies, and Used Cars and Trucks. Biggest rises: Motor Fuel, Lodging Away from Home, Jewelry and Watches, and Medical Care Commodities (pharma)
  • I skipped ahead to look at my guess for Median. It’s going to be a solid 0.2%, although that will cause the y/y to drop to “only” 2.80%. At least, that’s my estimate…won’t be reported for hours.
  • College Tuition and Fees at 3.86% y/y compared with 3.84% y/y.
  • Health Insurance doing its health insurance thing again.

  • I mean, on housing it’s not ALARMING how fast it’s growing. It isn’t way above our model or anything. It just looks bad compared to what people were expecting given the S&P Corelogic Case/Shiller index.

  • In green is the case/shiller y/y. So you can see people why were expecting a slowdown in rents. But you can also see that…it’s not a very good fit.

  • That’s not quite fair b/c there’s no lag incorporated…home prices lead rents by ~21 months, so really we shouldn’t even see that impact for a while. Here it is lagged. Still not a good fit though and at times (2011, 2014) the direction of shiller didn’t match even lagged.

  • Just a quick market comment…here’s the median CPI vs 10y inflation swaps. It’s going to be very hard to get much more bearish on long-term inflation swaps unless we see SOME signs that inflation is ebbing. So far, no signs at all.

  • Four pieces. First Food & energy:

  • Next, core goods. Our model has this headed higher, although not huge – maybe 0.5% or 1.0%. Recent deceleration is unsustainable especially in a fractious-trade world.

  • Core Services less Rent of Shelter. No real change this month. If this is going to go up, it is going to be because medical care rises. To this end, it’s interesting that the previous spikes in Health Care Insurance (shown earlier) preceded spikes in other Medical Care.

  • I wonder if the fact that Insurance is a residual means that when it is spiking, it means we’re just capturing prices in the wrong place until the survey catches up. Worth investigation.

  • Finally, Rent of Shelter. Clearly no disinflation here, yet.
  • I think that’s good for today. Don’t forget to stop by my blog (https://mikeashton.wordpress.com ), though I must admit I’ve been slack recently in writing – but that’s because business is very exciting right now. A little tariff, a little MMT talk, and the phone rings.

The upshot of all of this is that core CPI continues to give a bad read on where inflation has been. Core tells us that inflation is ebbing. But the median category in fact has been steadily rising for several years. That doesn’t mean the inflation dynamic won’t roll over, but merely that so far it has not. The Fed’s concern that inflation isn’t getting to its target is misplaced, although ironically if they are able to restrain interest rates then the velocity dynamic means inflation is probably not far from peaking. But I don’t think we know that yet.

Summary of My Post-CPI Tweets (April 2019)

Below is a summary of my post-CPI tweets. You can (and should!) follow me @inflation_guy. Or, sign up for email updates to my occasional articles here. Investors with interests in this area be sure to stop by Enduring Investments or Enduring Intellectual Properties. Plus…buy my book about money and inflation. The title of the book is What’s Wrong with Money? The Biggest Bubble of All; order from Amazon here.

  • CPI in under 10 minutes. Gentlefolk, start your engines!
  • Start with the consensus: this month economists are calling core 0.18% m/m, and 2.1% y/y.
  • Remember that last month, core was 0.11%, in a downside surprise driven by pharmaceuticals and autos, while Rents were actually somewhat bubbly again.
  • However, Median inflation turned out to be 0.26%, pushing y/y to basically tie the post-crisis highs at 2.77%.
  • That should lead you to suspect that there were some ‘tail effects’ last month that could be reversed this month. So that would make me marginally bullish this number, all else equal.
  • Now, there’s talk about the fact that the BLS is changing its collection method for Apparel to use a direct feed from retailers rather than manual price-sampling.
  • Some people think the change in the method of collecting Apparel prices should depress Apparel, but I’m not really sure why that would be so unless there was some systematic bias in collections pushing prices higher.
  • If so, I’m not sure it’s showing. Apparel is -0.76% y/y. In any event, Apparel is only 3% of CPI so effect should be quite small. And apparel recently has been weak. So I’m not too worried about that. Famous last words, I guess.
  • Core prints at 0.1%, 2.0% y/y. But that’s not as weak as it looks. It was actually something like 0.148%, whereas market was looking for 0.18% or so…y/y is 2.04%. So both barely rounded down.
  • last 12 months’ core CPI chart. Just bumping sideways. We ought to be back to 2.1% y/y next month, as we drop off a weak April 2018 print.

  • Well, trust the bow-tied set, I suppose. Apparel -1.94% m/m, -2.2% y/y. I guess those manual price checkers were pushing prices up, after all. (?)
  • And CPI for Used Cars and trucks, second month in a row, weak at -0.38%. That’s lower than Black Book (which has been a much better fit than Manheim since last year’s methodology change) suggests it should be.

  • But more importantly and lastingly – rents remained firm, with primary rents +0.42% m/m and OER +0.32% m/m. That keeps OER stable y/y and raises Primary rents to 3.68% y/y.
  • Primary rents y/y. Not sure if this is an aberration because I don’t track market rents. Seems unusual for late in the cycle, but wage growth has been strong and supports this dynamic. But seems a bit strong.

  • Pharma bounced, rising to -0.39% y/y from -1.19% y/y. But the downtrend doesn’t seem terribly damaged.

  • Core ex-housing drooped a little bit, not surprisingly given the breakdown. Core ex-shelter is 1.10%, down from a 1.54% November high but still well above the 2017 lows of 0.53%.
  • Interestingly, like last month where Used Cars fell and New Cars gained, the same thing happened this month. Used cars & trucks went to 0.44% y/y vs 1.11%; New cars to 0.72% from 0.29%. A little odd, but just wiggles.
  • Although Medicinal Drugs re-accelerated slightly, Professional Services (doctors)) decelerated to 0.39% from 0.97% y/y, as did Hospital and related services (1.94% from 2.12%). As a result, Medical Care WOULD have decelerated but for Health insurance.
  • Always worth a reminder: health insurance in the CPI is a residual, since CPI measures only the portion of medical care that individuals pay directly. But it rose to 9.06% y/y from 7.66%.

  • This chart is why we like to ignore core and focus on median. Clearly a lot of left-tail stuff going on.

  • Primary rents y/y. Not sure if this is an aberration because I don’t track market rents. Seems unusual for late in the cycle, but wage growth has been strong and supports this dynamic. But seems a bit strong.
  • So, having said that…my early guess at median CPI is for +0.27%, which would push median to 2.85%, clearly the highest since the end of the crisis. We will have to wait a couple of hours for the official figure.
  • Four pieces. Not much change this month except in the last piece. Here’s Food & Energy.

  • Piece 2: Core goods. Dragged down by used cars, pharmaceuticals. Our models have this still going higher so I think these are one-off effects.

  • Core services less rent-of-shelter. Doctors, hospitals dragging this down. Be wary if Medicare-for-all proposals start to gain traction; if they do then I’d suspect doctors and hospitals would start to raise prices before their prices get fixed or cut.

  • Part 4 is Rent of Shelter. I’ve been saying forever that we’re not getting deflation because this isn’t about to fall off a cliff. On the contrary, it’s actually moved above our ensemble model.

  • So, here’s our ensemble model for OER. Primary rents are actually a [little] bit above our model. As you can see, we’re expecting a gradual slackening of rental pressures. BUT…

  • …but our model based on income (not shown) rather than home prices is actually calling for higher rents. You can argue that higher wages have helped produce these higher rents.

  • But if that’s the case, it means that when inflation is actually rising, looking back at home prices is NOT the right way to do it. Indeed, if the wage hypothesis is the driver then we’d expect to see a divergence in Primary and OER rents that leads shelter costs higher.
  • ..there’s no real sign yet that primary rents are accelerating way past OER, but it’s something to keep an eye on if rent inflation continues to surprise on the upside.

  • That’s all for now. Thanks for tuning in.

The upshot of today’s report is that while there are lots of small one-offs that are making sharp moves lower, and each of them has the potential to cause month-over-month mischief, the broad body of prices is remaining stable and/or edging higher. Regardless of what happens to apparel (Women’s and Girls’ Apparel, Men’s and Boys’ Apparel, and Footwear accounted for the three largest declines this month) or used or leased cars and trucks, housing costs appear to be moving higher.

It is early to be certain about this, but there have been anecdotes about faster rent growth in places and there are some signs (as in the rent chart above) that these pressures are diffusing more broadly. With strong wage growth, it wouldn’t be terribly surprising if there was more household formation (there has been, although not a huge amount) and more pressure on rents as people move up. How this resolves is key to the medium-term outlook. If higher wages help to push rents higher, and continue to put downward pressure on the number of existing homes available for sale (see below, source Bloomberg), then core inflation is simply not going to droop lower in the way the Fed expects it will. If, on the other hand, this is just a temporary rise, then the one-off declines in core inflation will eventually be joined by soggy rents and core will drift somewhat lower.

Either way, I see little chance that core or median inflation will even remotely approach the lows from the last cycle, even if we enter recession later this year as I expect. To get there, housing would need to implode again and the dynamics are simply too healthy for that at the moment.

  • About 6 minutes to CPI. Consensus calls for 0.2% on core. The last few have been 0.20, 0.23, 0.18, and 0.24.
  • y/y core should stay at 2.2% after rounding – We are dropping off 0.174% and it would take a really weak figure to push y/y lower and a really strong one to make it round to 2.3%.
  • Last month, one of the big drivers was primary rents. Pundits saw last month’s CPI as very strong; I thought it was only slightly above expectations.
  • It’s surprising to see the forecasts at 0.2% on core, actually, given the narratives about how strong that inflation figure was, and how it came from Rents that many forecasters are bearish on. I thought we’d see 0.1% forecasts.
  • So we’ll watch primary rents of course, but I still think the trend in core goods is an interesting one to watch. Last month y/y core goods reached the highest level since 2013. Just barely out of deflation, but with the trade situation that’s where we want to watch.
  • So, here we go. Good luck all.
  • Yep, there we go. Core CPI only 0.11%, making the y/y 2.08%. Just when pundits were finally thinking inflation could be a “problem,” and stopped forecasting weakness…we get weakness!
  • Last 12. You can see why people were worrying if you cover the last bar. But the uptrend was not as big as it looked. And we’re really just bumping along in the 2.1-2.3% zone on core.

  • There are some interesting crosscurrents in this number. Remember how I said Rents were strong last month? They were again this month. Y/Y Primary rents rose to 3.51% from 3.43%; OER went to 3.32% from 3.21%. Lodging Away from Home another jump.

  • Other Goods and Services were +0.54% m/m, which is a big jump for a catch-all category. Worth drilling deeper. Medical Care and Recreation had big drops.
  • Core Goods dropped to 0.1% y/y from 0.3%. A significant contributor there was a decline in CPI-Used Cars and Trucks, which fell to 1.1% from 1.6% y/y. That’s not as big a deal as you think. But it’s big enough to matter at the margin in core goods.
  • Our model has core goods rising a bit further, and you can see that even a simple look like a correlation with core import prices suggests we should see a bit more. And with tariffs, hard to think the dip in core goods sticks.

  • I mentioned Used cars and trucks fell, but New vehicles rose to 0.29% y/y from 0.04%, reversing last month’s decline. Overall, used and new together (which is 7% of CPI!) fell to 0.49% from 0.92%.
  • Now let’s look at medical care. 1.73% y/y from 1.90% for the broad category. Medicinal drugs fell to -1.12% y/y from -0.36%. Again, core goods. Actually I wonder what core goods ex pharma and cars must have been doing so core goods only fell to 0.1% from 0.3% y/y!
  • Now this is really interesting. Pharma as I said was negative, and is continuing an amazing trend. But think this looks amazing?

  • Here’s what the pharma looks like in terms of level. Medicine prices have peaked? Is the move to biologics, which tend to be cheaper, accelerating and causing this? Or…

  • …or is this just another period like 2012-2013, when we had a temporary slowdown (driven by medicare if I recall) but then caught up? FWIW, my guess is that this slowdown represents a real evolution in care, though I don’t think we’ve seen the end of pharmaceuticals.

  • https://platform.twitter.com/widgets.js

  • Back to Medical Care: Professional Services fell to 0.97% from 1.16% y/y; Hospital and Related Services decelerated to 2.12% from 2.44%. This is helping hold down core services generally. But Health Insurance (which in CPI is a residual) rose smartly. Now 7.66% y/y from 6.46%.
  • Here’s health insurance. Only 1.1% of CPI, which is one way you know it’s just a residual. CPI accounts for the increase in care costs mostly directly so this chart doesn’t show the full story of what’s happening in insurance. But it’s a cool chart.

  • College Tuition and Fees rose to 3.13% from 2.93%. It has started to rise again partly because market returns were worse last year (60/40 was -2.4% and many other asset classes declined too).

  • Biggest declines on the month, with annualized rates of change: Car and Truck Rental (-57%), Jewelry and Watches (-34%), Leased Cars and Trucks (-18%), and Medical Care Commodities (pharma) (-11%).
  • Biggest increases on the month, with annualized rates of change: Misc Personal Goods (52%), Men’s and Boys’ Apparel (50%), Infants’ and Toddlers’ Apparel (33%), Fuel Oil and Other Fuels (21%).
  • This month we will again be reminded why looking at Median CPI matters. My guess at Median CPI is 0.26%, which would bring y/y back up to 2.78%. Won’t know for a few hours.
  • Lest we think that inflation markets behave rationally…here are 10-year inflation swaps in red, against current median CPI. Calling for a lot of deceleration that we’re not seeing in the data yet.

  • Core ex-shelter declined this month to 1.18% y/y from 1.39%. OK, so that’s one place we’re seeing deceleration. So you might say that inflation markets are betting on a serious deceleration in housing inflation.
  • Well, we see a slowdown in OER, but not such a large one that long-term inflation swaps look fair.

  • So for the cherry on top here are the four pieces charts. Each one is about a quarter of CPI, plus or minus, in order of least stable to most. First is Food and Energy.

  • Second piece is core goods. Setback this month, but I’m not convinced that used cars and trucks are leading the way on this series at the moment.

  • Core Services less Rent of Shelter. Here’s where the disinflationists need to make hay. And medical care inflation is helping them. Hard to see anything but a downtrend here at the moment.

  • On the other hand, Rent of Shelter – the most stable component – continues to NOT COLLAPSE as some are expecting it to. Yes, shelter costs are outrunning wage growth. But not so much any more, thanks to accelerating wages.

  • Actually, that wages/rents thing is a bit of a canard. Here is the Atlanta Fed’s Wage Growth Indicator vs Rent of Shelter. Wages have actually been keeping up fine with housing inflation. (& the increased cost of housing is one reason people are fighting for higher wages).

  • In conclusion, until I think of something else: last month CPI wasn’t as strong as people thought; this month is isn’t as weak as people think. With interest rates soggy the risk of a serious inflation debacle in this stroke of the economic cycle is receding. However…
  • …however, I do think that we are unlikely to see in the next recession anything like the dip we saw in the last recession. There’s a lot of good news in the figure right now. And when interest rates start to rise again, we’re going to see a higher high.

Summary of My Post-CPI Tweets (February 2019)

February 14, 2019 2 comments

Below is a summary of my post-CPI tweets. You can (and should!) follow me @inflation_guy. Or, sign up for email updates to my occasional articles here. Investors with interests in this area be sure to stop by Enduring Investments or Enduring Intellectual Properties. Plus…buy my book about money and inflation. The title of the book is What’s Wrong with Money? The Biggest Bubble of All; order from Amazon here.

I usually post these the day of CPI but I was traveling and didn’t get to do so. These were my tweets in the immediate aftermath of the CPI report.

  • About 15 minutes to CPI. Today’s stream-of-consciousness will be a little more relaxed since I’m at a conference in Florida at the moment!
  • As for the number today, here are some thoughts.
  • We’ve recently begun to see some reduction in pressure from truckload rates upstream. Not down, but rising more slowly. Bottlenecks in overland are easing somewhat. Higher prices are still passing through but less alarm about it.
  • Housing price increases have also been slowing. Again, we’re talking second-derivative stuff; they aren’t falling nationwide. Rents are loosely related to prices, so I don’t think we’ll see much downward pressure there yet, but it’s a meme at the moment.
  • Wage growth remains strong, but wages lag inflation so that’s not much illumination.
  • There is decent momentum in some other categories, and…tariffs. Remember we don’t need tariffs to get worse growth/inflation outcomes than the last 20 years; we just need less forward progress on trade. And we have that for sure! (Again with the second derivatives??)
  • I’ve been expecting an interim peak in median CPI later in 2019. It’s not here yet, and I might still be wrong about that and see it climb further. Inflation after all is a process with momentum. But that’s my current expectation.
  • However, I ALSO don’t expect that when median CPI eventually turns lower that it will fall anywhere close to the prior lows. I think we’ve begun a long-term cycle of higher highs and higher lows in inflation.
  • Now, money growth is picking up again, and higher rates over the last year imply higher velocity going forward. But globally we have more negative-rate debt, so that’s dampening. But the macro pressures on inflation remain to the positive side.
  • For today, the Street sees 0.2% on core, dropping y/y to 2.1% because drop off a difficult +0.3% comp from last January. The January figure sees a number of interesting cross currents. I suspect there’s a smidge of upside risk to this number, but I have low confidence on that.
  • We will see, in 5 minutes.
  • ok, 0.24% on core CPI, a bit higher than expected and BARELY kept core from rounding lower to 2.1%, even dropping off the strong Jan 2018

  • 15% is core to 2 decimal places y/y.
  • Primary rents 0.31% m/m after 0.21%, but y/y still declined to 3.43% vs 3.47%. As I said, rents only loosely related to prices and rent slowing has still been only at the margin.
  • Owners’ Equiv Rent was 0.27% vs 0.22% last, with y/y unchanged at 3.21%. So the big chunk of housing was reasonably strong. Actually Lodging Away from Home, which had a very large jump last month, had another decent rise this month. It’s only 0.9% of CPI but no “AirBnB” effect.
  • So the macro interesting thing is that core services declined to 2.8% y/y, thanks to the gradually slowing housing I think, while core goods rose to 0.3%.
  • That’s the highest core goods since 2013. Our models think this is headed up to 0.5% before flattening, but … tariffs. Our models don’t include them. This is the underlying pressure.

  • OK, so Apparel is 0.11% y/y, basically unchanged. Jump this month, but that looks seasonal. Medical care declined to 1.90% y/y vs 2.01%. Recreation rose to 1.36% vs 1.14%.
  • There was some chatter that a change the BLS made in how it accounts for quality change in some communications categories could drag down the CPI like cell phones did last year, but it’s a much smaller effect. Education/Communication was 0.31% y/y vs 0.21% last month.
  • Sorry for the interlude…some tech glitch. Anyway…picking up. Education was 2.72% y/y vs 2.62% last month; Communication was -1.68% vs -1.76%. So the rise in Education/Communication was from both parts.
  • Not so in Medical Care. Medical Care Commodities were -0.28% vs -0.50%; Med Care Services 2.45% vs 2.64%. So the overall small decline in Medical Care (1.90% vs 2.01% y/y) was basically entirely from the “Hospital and Related Services” category (2.44% vs 3.64%).
  • The other Medical Care categories – medicinal drugs, Professional Services, and Health Insurance – all rose. But they were counterbalanced by the Hospital part.
  • Median this month might be really interesting. Rough calculation suggests that a housing sub-category that Cleveland Fed calculates might be the median category so it’s hard to tell. But I think Median y/y will drop from 2.77% to 2.64%. Might even be worse.
  • Core ex-housing fell to 1.39% from 1.51%. So, there’s definitely some signs of softness here even though Core Goods is providing upward pressure. Working on the 4-pieces breakdown now.
  • Core ex housing chart. Sorry not too many charts today. Little harder to do remotely.

  • OK the four pieces. For those new to this analysis, I break CPI into these four pieces, each roughly 1/4 of CPI (19%-33%).

  • Here are the four pieces, from most-volatile to least-volatile. Part 1 is Food and Energy. Clearly holding down headline CPI but this is why we look through it. Look at that y axis!

  • Part 2 is Core Goods. With the trade frictions, this is presently the most interesting piece. Even if the tariffs implemented by the Administration are dropped, we’ve still stopped the forward trade momentum of the last quarter century. So this bears watching.

  • Core Services less Rent of Shelter. A lot of this is Medical Care, and while it looked like we might be breaking the long downtrend recently…maybe not so much.

  • Finally, rent of shelter. Off the highs, but our models don’t have it dropping seriously. Housing prices still rising, albeit more slowly. And rents, while high relative to wages, are now getting a following wind from rising wages. I suspect this will meander.

It seems, from reading the other post-mortems, that some people saw this as a very strong number. It really wasn’t…slightly stronger than expected. But I guess it depends on your state of mind coming in. I’ve thought the underlying run rate of core CPI was something like 0.22% per month, and with seasonal issues in January thought we’d be a touch higher than consensus. I suppose if you thought inflation was falling off a cliff you might have expected something much weaker. The composition, too, was solid but unspectacular. Again, if you thought rents were about to collapse then you were surprised that it was only down a little on a y/y basis. The core goods rise is important, but again – not unexpected.

So is inflation running “hot”? Well, if you think 2.2% is hot, I suppose so. But Median CPI also declined on a y/y basis, as have wages recently. Don’t get me wrong, I think inflation is still rising and probably will for most of this year. But it’s not shooting higher and if I were at the Fed and if I believed what they believed, I wouldn’t be alarmed by this number (I am not at the Fed and I don’t believe what they believe, for the record).

Summary of My Post-CPI Tweets (January 2019)

January 11, 2019 Leave a comment

Below is a summary of my post-CPI tweets. You can (and should!) follow me @inflation_guy. Or, sign up for email updates to my occasional articles here. Investors with interests in this area be sure to stop by Enduring Investments or Enduring Intellectual Properties. Plus…buy my book about money and inflation. The title of the book is What’s Wrong with Money? The Biggest Bubble of All; order from Amazon here.

  • A few minutes to CPI. Consensus 0.2%, 2.2% y/y on core, pretty much on the dot. That’s slightly lower on core than last month, which ALMOST rounded to 2.3%, but dropping off a strong Dec ’17. Remember Median is 2.82%, near the highs.
  • it will be hard to get a ‘handle surprise’ on core CPI today. But watch Apparel, which has been weirdly weak despite tariff tensions. Used cars/trucks has been strong for a couple months and is due to be back normal, but not to “retrace” as it was too low before.
  • In general, look at core goods, which last month went flat after a long time in deflation. And keep an eye on core-ex-shelter, which is near multi-year highs.
  • 21% on core, 2.21% y/y. Basically a consensus number.
  • Pretty stable last few months of core.

  • Core goods 0.1% y/y, down from 0.2% y/y last month. Core Services unch at 2.9% y/y.
  • Core goods right on schedule.

  • OER 0.23% m/m, dropping y/y because of base effects back to 3.22%. Had been a y/y bounce last year because of those base effects but now pretty much back to trend. Primary rents 0.20%, 3.48% y/y, also down.
  • Inflation bears will point at “Lodging Away from Home,” +2.74% m/m, and say that is an aberration. But it’s really just reversing a very weak recent aberration. Y/y up to 0.91%; had been -1.37%. So ignore those people.
  • Pharma was weak, at -0.43% m/m and -0.58% y/y.

  • Doctors services also remains fairly low. Hospital Services however accelerated to 3.67% y/y from 3.52% y/y. Overall, Medical Care was roughly steady at 2% y/y.

  • Used Cars and Trucks was -0.18%, dropping y/y to 1.43% vs 2.30%. It was due to decelerate, and that’s roughly in line.

  • Apparel is back to positive y/y, at +0.3% vs -0.6%, but that’s mostly base effects. Only very small rise this month. That continues to be a head-scratcher. I’d expect to see trade frictions show up in apparel quickly. But this is a Dec number, and so maybe stockpiling pre-xmas.
  • Core ex-housing was 1.50% y/y, down slightly from 1.53% y/y last month. That remains near 5-year highs, but still waiting for the break higher.
  • Core ex-shelter chart.

  • By the way, if you have kids I hope they’re girls. In apparel, Boys’ apparel is +13.1% y/y…Men’s footwear is +4.3%…nothing else is over +0.5%.
  • Recreation is a pretty small part of CPI (5.7%), but rose from 0.61% y/y to 1.16% y/y. Inflation in Cable and Satellite Services, Pets and Pet Products, and “Admissions” were the main culprits. Pets are “recreation?” I think of them more as Transportation. Or Food.
  • Just kidding.
  • College Tuition and Fees +2.7% y/y, up a small amount but continuing to run ahead of headline and core.
  • Looks like a regional housing index will be the median category this month, which means my median guess isn’t as sharp. My estimate is 0.23% m/m, making the y/y 2.80% down from 2.83%. Median is a better measure of inflation trend since it ignores outliers.
  • This is an important chart. It shows Median CPI (without today’s number, not out yet) vs 10-year inflation swaps. You can see how bearish the market has gotten recently. Some of this is oil but these are 10y swaps so that shouldn’t matter much.

  • I almost forgot to mention that Wireless telephone services weakened again to -3.19% from -3.03% y/y. More interestingly, Land-line went to -0.02% from 0.46%. Even more interesting, land-line spending is only about a third as large as wireless. Here’s a chart of landline.

  • Let’s wrap this up with the four-pieces charts. First piece is food & energy. Weirdly linear deceleration.

  • The piece I think is a very important story going forward: core goods. Out of deflation and I think it’s going higher. This is where trade tensions are most important.

  • Core services less Rent of Shelter…still look to be in a downtrend, mostly thanks to medical. If we’re going to have an inflation accident, it should also show up here.

  • Rent of Shelter. Going nowhere fast. And that means you’re not getting deflation any time soon.

  • Final thought: next month we drop off a +0.35% m/m from core (from Jan ’18), which means it is pretty likely we see a drop in core towards 2%. That makes a Fed hike harder. But then the comparisons get easier, as my 12-month m/m core CPI chart showed.
  • Core is unlikely to drop below 2% any time soon, and in my view we’re likely to see 2.5% before 1.9%, and median inflation above 3% before long. But the Fed has a couple months’ reprieve before the choices get tougher.
  • That’s all for today. Thanks for tuning in.

Today’s CPI number is an acceptable one for the Fed. Right on the screws, showing no unanticipated accelerations. But also, no decelerations! Next month, core should decelerate, but that is likely to be the last good news for a while on inflation. Now, there are some reasons to think that the upward trend on inflation might be ending sooner than I have thought, and I’ll get into those reasons over the next week or two. But for now, the story is that the Fed has some breathing room to stop and watch for a while, and avoid some critical Presidential tweets while seeming to be principled. The difficult test will come in a few months when inflation starts heading higher even while growth, and stock markets, head lower. It may well be that we have seen the last tightening for a while – if the Fed Chair were Bernanke or Yellen, they’d already be easing, but Powell seems to be made of sterner stuff (but read my prior post about whether there is a Powell put). However, it has been easy up until now, with growth strong enough to take some hikes, inflation heading the wrong direction, and rates below any semblance of neutral. The next year or two is where the Fed’s job gets difficult as they have to navigate crosscurrents.
