  • core CPI+0.13%, softer than expected. Core y/y rose from 1.77% to 1.80% due to soft year-ago comparison.
  • Next month we drop off an 0.05%, so we will almost surely get a core uptick. Surprising we haven’t yet. Waiting for breakdn.
  • Both primary rents and owners’ equiv accelerated slightly, Which means core EX HOUSING was actually slightly down m/m
  • core services rose to 2.6% (mostly on housing); core goods fell to -0.5% from -0.4% y/y. Same story overall.
  • Apparel accelerated to -1.64% from -1.85% y/y. Story for years in apparel was deflation; in 2011-12 prices rose>>
  • >>and looked like return to pre-90s rate of rise. Then it flattened off, and has been declining again.
  • Apparel could well be a dollar story now – it’s almost all made overseas, almost no domestic competition so dollar matters.
  • our proxy for core commodities is apparel + cars + med care commodities. all 3 decelerated. Cars went from +0.5% to 0.0% y/y.
  • sorry, Apparel actually ACCELERATED to -1.6% from -1.9%, but still negative.
  • airfares not really a story. -5.6% y/y vs -5.2% y/y. The NSA number dropped but it always drops in late summer. [Ed note: see chart below]
  • airfares was -8.5%, but it was -8.1% last july, -2.9% in 2013, -2.6% in 2012…no story there. didn’t affect core meaningfully.
  • Primary rents 3.56% from 3.53%. OEW 3.00% from 2.95%. Both will continue to rise.
  • Lodging away from home also rebounded to 2.9% y/y after a one-off plunge to 0.8% y/y last month. Household energy of course down.
  • Transportation accelerated (-6.6% y/y vs -6.9%) on small motor fuel recovery. btw, airline fares are only 0.7% of CPI, so 0.9% of core.
  • Med Care: goods were dn (drugs 3.2% vs 3.4%,equipment -0.9% vs 0.0%) but prof services up (2.1% vs 1.8%),hospital svcs dn (3.2% vs 3.5%)
  • Health insurance only +0.9% y/y vs 0.7%, but more expenditures out-of-pocket under the ACA so higher infl for those categories hurts.
  • Median (due out later) might only be +0.1% this month. I have it cuffed at 0.15% but I don’t seasonally-adjust the housing sub-components.
  • Last yr Median was +0.17% m/m, so best guess is it roughly holds steady at 2.3%.
  • I don’t see how the Fed embarks on a meaningful tightening in Sep, with global economy weaker than it has been in a couple yrs.
  • Median inflation and growth plenty strong enough to “normalize” rates but that’s not a new story.
  • I’ve been saying they should tighten for a few years but not sure why they would NOW if they didn’t in 2011.
  • But Fed doesn’t use common sense or monetarist models.It’s all DSGE;who knows what those models are saying?Depends how they calibrated.
  • FWIW our OER models diverge here. Our nominal model says pressures on core start to ebb in a few mo; our real model predicts more rise.
  • I like the real model as it makes mose sense…but it’s not tested in a real upswing.
  • US #Inflation mkt pricing: 2015 0.8%;2016 0.7%;then 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, & 2025:2.2%.
  • …so inflation market doesn’t see inflation at the Fed’s target (about 2.2% on CPI vs 2.0% on PCE) until 2023.
  • The market is not CORRECT about that, but another reason the Fed can defer tightening if they want to. And they have always wanted to.

First, let’s start with the airfares chart. One of the early headlines was that airfares plunged by the most since some long-ago year, which held down core. Well, here is the chart of airfares, non-seasonally adjusted. You tell me whether this is unusual to have airfares fall in July.


Because this is part of a normal seasonal pattern, the year-on-year figure was only slightly lower, as I note above. And airfares are a tiny part of CPI, less than 1% of the core. This is not a story.

More important will be the median CPI. This is a much better measure of the central tendency of prices than headline or core, both of which (as averages) can be skewed by a few categories having outsized moves. Median inflation has been ticking higher (see chart below) but will probably go sideways this month.


Finally, the most important chart. There are lots of ways to model housing. If you model rents as lagged versions of the FHFA Home Price Index, or Existing Home Sales median prices, then you get one model and that model suggests that rents should begin to moderate over the next 6-12 months. Not that they will decelerate markedly, but that they will stop accelerating and therefore stop being the driving force pushing core CPI higher. But if you use those models, you have to recognize that you are calibrating over a period of very slow inflation, so that you are effectively ignoring the knock-on effect of higher inflation on rents. That is, if core inflation is around 2% and rents are 3%, then if core inflation rises to 5% you wouldn’t expect rents to be at 3%. So, you need to use a model that recognizes the interrelationship between these variables. And that sort of model implies that rents will continue to climb. Both models of Owners’ Equivalent Rent are shown in the chart below. I prefer the “real” model to the “nom” model, but we don’t know the right answer yet.


Even if OER moderates it doesn’t mean that CPI will stop rising; it just means that the story will stop being all about rents. Core goods still have a long ways to go to normalize, and that might be the next story. But for now, I am still focused on rents.

As I said, I really don’t see how the Fed can think about hiking rates in September based on the data we have seen recently. Yes, inflation is on the border of being an issue, but that has been true for a long time. In 2011, there was plenty of growth and while high rates would not have been warranted, it is hard to argue that normal rates were not called for. And yet, we got QE and more QE. This will end up being the biggest central bank error in decades, regardless of what the Fed does in September. I doubt they will hike, and if they do then it won’t be a long series of hikes. This is still a very dovish central bank, and they will get skittish very quickly if markets balk at more expensive money – which, of course, they are wont to do.


Summary of my Post-CPI Tweets

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.

  • Core CPI +0.18%, y/y rises to 1.77%. Pretty much as-expected on the headline figures.
  • Was some market concern about a possible higher print following PPI, but there isn’t much correlation.
  • Note that the next two months of CPI will ‘drop off’ an 0.10% and an 0.05%, so we should get to 2% on core inflation by mid-September.
  • Of course the Fed’s target is ~2.25% on core CPI (since they tgt core PCE) so Fed can argue it’s still below tgt. Uptrend may concern.
  • Housing inflation on the other hand going to the moon
  • This is great chart and it’s the reason core never had a chance of entering deflation territory. & will go up. (retweeted Matthew B)


  • Housing #CPI overall just hit 2% y/y. Primary rents 3.53%. OER, which is 24% of the whole CPI, rose to 2.95% from 2.79%. Wow!
  • …our model for OER is at 3.1%, and the actual number HAD been lagging. I love it when a plan comes together.
  • So housing drove core services to +2.5% y/y, core goods -0.4%.
  • So if housing busted higher, what was the services offset? Medical care, 2.51% y/y vs 2.84% last month.
  • WSJ argued earlier this month that is expected because under Ocare people are actually spending their own money.
  • Within medical care, drugs went to 3.44% vs 4.05%, pro svcs went 1.83% from 1.58%, and hospital & related to 3.48% from 4.51%. So maybe?
  • Yes, core PCE & core CPI are going to be rising. But core PCE won’t be anywhere close to the Fed’s tgt by Sep.
  • Here is core and median CPI (the latter not out yet today) and core PCE.


  • core commodities are about where they should (eventually) be, given rally in TW$. A bit ahead of schedule though.


  • This chart means either that home prices are overextended or incomes need to catch up, or both.


  • Here is our OER model that is based on incomes. Not a tight fit but gets direction right.


  • I wondered about this when I paid $180/night for room in S. Dak. Hotel infl driven in part by fracking boom?


  • probably would fit better if I used a regional lodging index rather than national, I suspect.

The summary of today’s CPI release is that the underlying pressures remain the same, and the trends remain the same. The really interesting dynamic going forward isn’t in CPI (although at some point when core goods starts to rise again, that will be quite interested), but in how the Fed reacts to the CPI. When they meet in September, core CPI will be around 2%, a bit shy of where the Fed’s target is. But the uptrend will be clearly apparent, and core and median CPI will likely be closer to 2.5% than 2% by the end of the year.

So the interesting dynamic is this: even though inflation is below the Fed’s target, and growth isn’t great shakes, and there are risks to the global economic system in Europe and in China…will the Fed tighten in September anyway? If they do, then it will be surprising if only because the FOMC passed on many opportunities over the last five years which would have been much more accommodating (no pun intended) to a normalization of rates. Sure, if they now recognize that they should have tightened three years ago it shouldn’t color their decision today – the best time to plant a tree may have been thirty years ago, but the best time that we can actually choose from is today – but the Fed hasn’t usually been so limber in its reasoning. Especially with a very dovish makeup of the Committee, I would be surprised to see them hike rates unless inflation has surpassed their target and growth is pretty strong with global risks receding.

However, the strength of my view on that has been slipping recently. Although I think most of the Fed’s talk on this point is mere bluster, we do have to pay attention when Fed speakers – and especially the Chairman – say the same things multiple times. While Yellen has expressed only an expectation that the Fed will raise rates later this year (and we have no idea how conditional that expectation is on stronger growth, on Chinese growth, on European volatility etc, she has said this multiple times and at some point I have to conclude she means it. I still think that the odds of getting rates even up to 1% in a single series of moves is slim, but I admit the more-consistent Fed chatter is worth listening to.

Summary of My Post-CPI Tweets

April 17, 2015 3 comments

Below you can find a recap and extension of my post-CPI tweets. You can 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.

  • Core CPI+0.23% m/m is the story, with y/y upticking to 1.754% (rounded to +1.8%). This was higher than expected, by a smidge.
  • Core services +2.4% y/y down from 2.5%. But core goods -0.2%, up from -0.5% last mo and -0.8% two months ago. Despite dollar strength!
  • Core ex-housing rose to 0.91% y/y from 0.69% at the end of 2014. Another sign core inflation has bottomed and is heading back to median.
  • The m/m rise of 0.20% in core ex-shelter was the highest since Jan 2013.
  • Primary rents 3.53% y/y from 3.54%; OER 2.693% from 2.687%. Zzzzz…story today is outside of housing, which is significant.
  • Accelerating major groups: Apparel, Transport, Med Care, Recreation (32.1% of index). Decel: Food/Bev, Housing, Educ/Comm, Other (67.9%)
  • …but again, in housing the shelter component (32.7% of overall CPI) was unch at ~3% while fuels/utilities plunged to -2.26% from flat.
  • [in response to a question “Michael we have been scratching our heads on this one… is it some impact of port strike do you think?”] @econhedge I don’t think so. But core goods was just too low. Our proxy says this is about right.
  • @econhedge w/in core goods, Medical commodities went to 4.2% from 3.9%, new cars from 0.1% to 0.3%, and Apparel to -0.5% from -0.8%.
  • @econhedge so you can argue Obamacare effect having as much impact as port strike. But it’s one month in any case. Don’t overanalyze. 🙂
  • Medicinal drugs at 4.46% y/y. In mid-2013 it was flat. That was a big reason core CPI initially diverged from median. Sequester effect.
  • @econhedge Drugs 1.70%, med equip/supplies 0.08% (that’s percentage of overall CPI). 8.7% and 0.4% of core goods, respectively.
  • Median should be roughly 0.2%. I have it up 0.21% m/m and 2.22% y/y, but I don’t have the right seasonals for the regional OERs.
  • Further breakdown of medical care commodities: the biggest piece was prescription drugs, +5.74% y/y vs 5.19%. The other parts were lower.

The main headline of the story is that core inflation rose the most month-over-month since May. After a long string of sub-0.2% prints (that sometimes rounded up), this was a clean print that would annualize to 2.7% or so. And it is no fluke. The rise was broad-based, with 63% of the components at least 2% above deflation (see chart, source Enduring Investments, and keep in mind that anything energy-related is not part of that 63%) and nearly a quarter of the basket above 3%.


This is no real surprise. Median has consistently been well above core CPI, which implied some “tail categories” were dragging down core CPI. These tail categories are still there (see chart, source Enduring Investments), but less than they had been (compare to chart here). Ergo, core is converging upward to median CPI. As predicted.


The next important step in the evolution of inflation will be when median inflation turns decisively higher, which we think will happen soon. But that being said, a few more months of core inflation accelerating on a year/year basis will get the attention of the moderates on the Federal Reserve Board. I don’t think it will matter until the doves also take notice, and this is unlikely to happen when the economy is slowing, as it appears to be doing. I don’t think we will see a Fed hike this year.

Summary of my Post-CPI Tweets

Below you can find a recap and extension of my post-CPI tweets. You can 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.

  • core CPI +0.157%, so it just barely rounded to +0.2%. Still an upside surprise. Y/Y rose to 1.69%, rounding to 1.7%.
  • y/y headline now +0.0%. It will probably still dip back negative until the gasoline crash is done, but this messes up the “deflation meme”
  • (Although the deflation meme was always a crock since core is 1.7% and rising, and median is higher).
  • Core ex-housing +0.78%. Still weak.
  • Core services +2.5%. Core goods -0.5%, which is actually a mild acceleration. So the rise in core actually came from the goods side.
  • Accelerating major cats: Apparel, Transp. Decel: Food/Bev, Housing, Med care, Recreation, Other. Unch: Educ/Comm. But lots of asterisks.
  • Shelter component of housing rose back to 3% (2.98%) y/y; was just fuels & utilities dragging down housing.
  • Primary rents: +3.54% y/y, a new high. Owners’ Equiv Rent: 2.69%, just off the highs.
  • In Medical Care, Medicinal Drugs 4.13% from 4.16%, but pro services +1.47 from +1.71 and hospital services 3.28% from 4.08%.
  • In Education and Communication: Education decelerated to 3.5% from 3.7%; Communication accel to -2.2% from -2.3%.
  • 10y breakevens +3bps. Funny how mild surprises (Fed, CPI) just run roughshod over the shorts who are convinced deflation is destiny.
  • No big $ reaction. FX guys can’t decide if CPI bullish (Fed maybe changes mind and goes hawkish!) or bearish (inflation hurts curncy).
  • Here’s my take: Fed isn’t going to be hawkish. Maybe ever. So this should be a negative for the USD.

This CPI report was a smidge strong, but just a smidge. The market was looking for something around 0.12% or so on core, and instead got 0.16%. To be sure, this is another report that shows no sign of primary deflation, but still it amazes me that inflation breakevens can have such a significant reaction to what was actually just a mild surprise. That reaction tells you how pervasive the “deflation meme” has become – the notion that the economies of the world are headed towards a deflationary debt spiral. I am not saying that cannot happen, but I am saying that it will not happen unless somehow the central banks of the world decide to stop flushing money into the system. And honestly, I see no sign whatsoever that that is about to happen.

As I wrote last week, it should be no surprise that this is a dovish Fed that will perpetually look for reasons to not tighten, and will do so only when the market demands it. My guess is that will happen once inflation, breakevens, and rates rise, and stocks fall. And this doesn’t look imminent.

Outside of housing, core inflation still looks soft. But housing inflation is accelerating further, as has been our core view for some time. The chart below (data source: Bloomberg) shows the y/y change in primary rents is at 3.54%. The median in primary rents for the period for 1995-2008 (the 13 years leading up to the crisis) was 3.20%. And during that time, core inflation ex-housing was 1.72% (median).


Like most data, you can use this to argue two diametrically-opposed positions. You might argue that the Fed’s loose money policy has helped re-kindle a bubble in housing, as inflation in rents of 3.54% with other core prices rising at 0.78% suggests that housing is in a world of its own. Therefore, the Fed ought to be removing stimulus, and tightening policy, to address the bubble in housing (and the one in equities) and to keep that bubble from bleeding into other markets and pushing general prices higher. But the flip side of the argument is that core inflation outside of housing is only 0.78%, so therefore if the FOMC starts removing liquidity then we may have primary deflation, ex housing. Accordingly, damn the torpedoes and full steam ahead on easing.

The data itself can be used right now to make either argument. Which one do you think the Fed will make?

Follow-up question: given that the Fed has historically one of the worst forecasting records imaginable, which argument do you think is actually closer to correct?


Crazy Spot Curves – Orderly Forwards

January 30, 2015 2 comments

This is an interesting chart I think. It shows the spot CPI swap curve (that is, expected 1y inflation, expected 2y compounded inflation, expected 3y compounded inflation), which is very, very steep at the moment because of the plunge in oil. It also shows the CPI swap curve one year forward (that is, expected inflation for 1y, starting in 1y; expected inflation for 2y, starting in 1y; expected inflation for 3y, starting in 1y – in other words, what the spot curve is expected to look like one year from today). The x-axis is the number of years from now.

efficientThe spot curve is so steep, it is hard to tell much about the forward curve so here is the forward curve by itself.

efficient2Basically, after this oil crash passes through the system, the market thinks inflation will be exactly at 2% (a bit lower than the Fed’s target, adjusting for the difference between CPI and PCE, but still amazingly flat) for 6-7 years, and then rise to the heady level of 2.10-2.15% basically forever.

That demonstrates an amazing confidence in the Fed’s power. Since inflation tails are longest to the high side, this is equivalent to pricing either no chance of an inflation tail, or that the Fed will consistently miss on the low side by just about exactly the same amount, and that amount happens to be equal to the value of the tail more or less.

But what is really interesting to me is simply how the wild spot curve translates so cleanly to the forward curve, at the moment.

Summary of My Post-CPI Tweets

December 17, 2014 2 comments

Below is a summary of my post-CPI tweets. You can follow me @inflation_guy :

  • 1y inflation swaps and gasoline futures imply a 1-year core inflation rate of 0.83%. Wonder how much of that we will get today.
  • Very weak CPI on first blush: headline -0.3%, near expectations, but core 0.07%, pushing y/y core down to 1.71% from 1.81%.
  • Ignore the “BIGGEST DROP SINCE DECEMBER 2008” headlines. That’s only headline CPI, which doesn’t matter. Core still +1.7% and median ~2.3%
  • Amazing how core simply refuses to converge with median. Whopping fall in used cars and trucks and apparel – which is dollar related.
  • Core services +2.5%, unch; core goods -0.5%, lowest since 2008. But this time, we’re in a recovery.
  • Medical Care Commodities, which had been what was dragging down core, back up to 3.1% y/y. So we’re taking turns keeping core below median.
  • Core ex-housing declines to +0.800%, a new low.
  • That’s a new post-2004 low on core ex-shelter.
  • Accel major groups: Food, Med Care (22.5%) Decel: Housing, Apparel, Transp, Recreation, Educ/Comm, Other (77.5%). BUT…
  • But in housing, Primary Rents 3.482% from 3.343%, big jump. Owners’ Equiv to 2.707% from 2.723%, but will follow primaries.
  • Less-persistent stuff in housing responsible for decline: Lodging away from home, Household insurance, household energy, furnishings.
  • Real story today is probably Apparel, which is clearly a dollar story. Y/y goes to -0.4% from +0.6%. Small weight, but outlier.
  • Similarly used cars and trucks, -3.1% from -1.7% y/y (new vehicles was unch at 0.6% y/y).
  • On the other hand, every part of Medical Care increased. That drag on core is over.
  • Curious is that airfares dropped: -3.9% from -2.8%. SHOULD happen due to energy price declines, but in my own shopping I haven’t seen it.
  • I don’t see persistence in the drags on core CPI. There’s a rotation in tail-event drags, which is why median is still well above 2%.
  • We continue to focus on median as a better and more stable measure of inflation.
  • Back of the envelope calc for median CPI is +0.23% m/m, increasing y/y to 2.34%. Let’s see how close I get. Number around noon. [Ed. note: figure actually came in around 0.15%, 2.25% y/y. Not sure where I am going wrong methodologically but the general point remains: Median continues to run hotter than core, and around 2.3%.]

Quite a few tweets this morning! The number was clearly roughly in-line on a headline basis: gasoline prices have dropped sharply, in line with crude oil prices. How much? Motor Fuel dropped from -5.0% y/y to -10.5% y/y. The monthly decline was over 6%, and so a decline in headline inflation on a month/month basis was all but certain. Had core inflation been as low now as it was in 2010, we would have seen a year-on-year headline price decline (as it is, headline CPI is +1.3% y/y).

However, core inflation is not as low as it was in 2010. It continues to surprise us by failing to converge upwards to median CPI. Last year, the reason core CPI was inordinately low compared to the better measure of central tendency (median) was that Medical Care inflation was weak thanks to the effects of the sequester. But that effect is now gone. Medical Care inflation is back to 2.5% on a year-on-year basis; this month’s print was the highest in over a year. The chart below (Source: Bloomberg) shows the y/y change in Medical Care Commodities (e.g. pharmaceuticals) – back to normal.


The 2013 dip is very clear there, and the return to form is what we expected, and the reason we expected core inflation to return to median CPI. But it hasn’t yet; indeed, core is below median by around 0.6%, the biggest spread since 2009. Now, it may be that core is simply going to stay below median for an extended period of time as one category after another takes turns dragging core lower. From 1994-2009, core was almost always lower than median. That was a period of disinflationary tendencies, and the fact that different categories kept trading off to drag core CPI lower was one sign of these tendencies.

I do not think we are in the same circumstances today. Although private debt levels remain very high (weren’t we supposed to have had deleveraging over the past six years? Hasn’t happened!), public debt levels have risen dramatically and the latter tends to be associated with inflation, not deflation. Money supply, especially here in the US, has also been growing at a pace that is unsustainable in the long run and it seems unlikely that the Fed can really restrain it until they drain all of the excess reserves from the system. These are inflationary tendencies. The risk, though, is that the feeble money growth in Europe could suck much of this liquidity away and move global inflation lower. This is an especially acute risk if Japan’s monetary authorities lose their nerve or if other central banks rein in money growth. In such a case, global inflation would decline so that, while US inflation rises relatively, it falls absolutely. I don’t consider this a major risk, but it is a risk which is growing in significance.

Of course, all of that and more is priced into inflation-linked bond and derivative markets, as well as in commodities. Only a massive and inexplicable plunge in core inflation could render the market-based forecasts correct – and there is no sign of that. Housing inflation continues to rise, and the soonest we can see that peaking is late next year. Getting core inflation to decline appreciably while housing inflation is 2.6% and rising is very unlikely! Accordingly, we see inflation-linked assets as extremely cheap currently.

Summary (and Extension) of My Post-CPI Tweets

July 22, 2014 2 comments

Below is a summary (and extension) of my post-CPI tweets today. You can follow me @inflation_guy.

  • CPI +0.3%/+0.1% with y/y core figure dropping to 1.9%. That will be only by a couple hundredths on rounding, but it’s still a decline.
  • Looks like core was 0.129% rounded to 3 decimal places. y/y went from 1.956% to 1.933% so a marginal decline.
  • RT of Bloomberg Markets @themoneygame: Consumer Price Changes By Item 
  • Core goods still -0.2%, core services still +2.7%, unchanged from last month. [ed note: I reversed these initially; corrected here]
  • All of this a mild miss for the Street, which was looking for +0.19% or so, but I though the Street was more likely low.
  • Major groups accel: Apparel, Recreation, Educ/Comm, Other (19.7%). Decel: Food/Bev, Transp, Med Care (38.9%), Housing flat.
  • There’s your real story. Recent drivers: medical care, which is a base effect and oddly reversed. That’s temporary. Also>>
  • >>big fall in non-rental/OER parts of housing: insurance, lodging away from home, appliances. Those are not as persistent as rents.
  • Primary rents went to 3.153% from 3.058%; OER unch at 2.640% from 2.638%. The rest will mean-revert.
  • College tuition and fes at 4.142% from 4.001%.
  • 60.5% of all low-level categories accelerating (down from 70.5%). Still broad but not as broad.
  • Actually looks like Median CPI could downtick today.

This is why I try very hard to resist the urge to forecast the monthly CPI, and admonish investors (and even traders) to resist trading on the data. Chairman Yellen is right about this: the data are noisy, so one month can be almost anywhere. This month, there was a reversal in the recent rise in y/y medical care inflation. But that rise was due to base effects, which aren’t going away, so forecasting medical care inflation to continue to accelerate is more a statement of mathematical likelihood than it is an economic forecast. And it’s all the more surprising then when it reverses.

This month’s figure makes it a fair bit harder for my forecast of near-3% for 2014 on core or median inflation to come to pass, although it bears noting that median inflation (even though it may downtick later today) is still within striking distance. Since median is currently the better measure, and will be for much of this year, I won’t back off my forecast yet. Another weak month, though, would cause me to ratchet down the target simply because it becomes harder to hit as time becomes shorter.

However, I expect several months this year will exceed +0.3% on core inflation. And it is worth remembering that core inflation faces easy year-ago comparisons for the rest of the year. In July of last year, the seasonally-adjusted m/m core inflation figure was +0.167%; in August it was +0.138%; in September it was 0.132%; in October +0.124%; in November +0.175%; and in December +0.101%. So, even if core inflation only averages +0.2% for the rest of the year, core will still be at 2.3% by year-end. If core inflation averages what it has been for the last four months, we’ll be at 2.4%. What that means is that (a) my forecast of something near 3% doesn’t represent a massive acceleration, although we only have half a year to get there, and (b) anyone forecasting less than 2.3% by year-end is actually forecasting a deceleration in inflation from recent trends.

The breadth indicators also took a mild breather this month, with the proportion of the CPI that is accelerating (looking at low-level categories) dropping to around 60% from around 70% in May. As with the other analysis, however, we should be careful not to read too much into one month since this figure also jumps around a lot. Interestingly, the proportion of categories where the year-on-year change is at least 2 standard deviations above zero – so that we can reject the ‘deflation’ meme for these categories – is basically unchanged from last month at 24%. As the chart below shows, we last saw a level this high in 2006, which is also the last time that core CPI ran at 3%.


Housing inflation is now back below my model’s projections, inflation breadth is still high, and the persistent parts of CPI are maintaining their levels or advancing while a few of the skittish parts are retreating (or at least not yet converging to the mean). There is nothing here to indicate that the three months of accelerating core CPI were the aberration; in fact to me it appears that the June figure was the aberration. That question will be answered over the balance of the year. In the meantime, inflation markets remain priced at levels so low that even if you’re wrong in betting on higher inflation, you don’t lose much but if you’re right, you do very well. In my view (although admittedly I may be biased), most investors remain significantly underweight protection against this particular risk.
