  • Why markets saw it differently

 

  • US headline / core CPI, m/m % change, SA, March:
  • Actual: 0.1 / 0.4
  • Scotia: 0.2 / 0.3
  • Consensus: 0.2 / 0.4
  • Prior: 0.4 / 0.5

US core inflation remains hot with no satisfying progress toward achieving the Fed’s 2% inflation target. So why did markets react the way they did, at least so far?

The 2-year Treasury yield fell by about 19bps at first and has cut that to 10bps. S&P equity futures initially spiked 0.9% higher post-data but have reined that in to about half of the initial rally. The dollar depreciated by about ½% on a DXY basis.

One possibility is that markets had been positioned for an even hotter core reading than the hot reading we got and so off-base position squaring swung around in the opposite direction. Another possibility is that traders looked at the wrong number again—like they did with Eurozone figures earlier this year—by reacting to a one-tick downward surprise to headline CPI at 0.1% m/m. I guess a third possibility is that markets are still looking at the year-over-year measure that saw headline inflation drop by a full percentage point to 5% even though the year-over-year core gauge moved up a tick to 5.6% Who knows, maybe traders typed ‘what should I do after CPI’ into ChatGPT and it told them to buy 2s. Either way, I don’t view the market reaction as indicative of how the FOMC will take the numbers.

Key is that core CPI excluding food and energy was up by 0.4% m/m and when annualized translates into a 4.7% m/m annualized rate (chart 1). The 3-month moving average is now set at 5.11% which is basically unchanged from the prior month’s 5.17%. Underlying price pressures remain quite firm and way above the Fed’s 2% PCE target.

We also see that in the CPI analog to Chair Powell’s favourite measure which is core PCE services inflation excluding housing. The CPI proxy for this was up by 3.6% m/m SAAR in March. It had surged by 6.2% in February as the hottest reading since September so call it cooler if you wish, but the smoothed 3-month moving average trend only ebbed by three-tenths to 4.4% at a seasonally adjusted and annualized rate. The trend remains too hot for the FOMC’s comfort (chart 2).

Charts 3 and 4 show the breakdown of m/m price changes by category and the weighted contributions to the overall change in CPI respectively. Charts 5 and 6 do the same things for the year-over-year rates that are more driven by base effects as opposed to the m/m pressures that indicate fresher evidence of inflationary pressures at the margin.

Chart 5: March 12-Month Changes in US Headline CPI Categories; Chart 6: March Weighted Contributions to the 12-Month Change in US Headline CPI

Charts 7 through 13 break down select parts of the basket.

Chart 7: US Goods vs Services Inflation; Chart 8: US Food Prices; Chart 9: New vs Used Vehicle Inflation; Chart 10: US Apparel
Chart 11: US Airfare; Chart 12: US Home Prices & Rent; Chart 13: US Financial Services

The accompanying table provides a richer breakdown of the basket including micro charts and z-score measures of deviations from historical averages.

Overall we have firm core CPI inflation and nonfarm payrolls and the decision on May 3rd may have enough evidence to go with in support of +25bps. Next up will be Q1 GDP on April 27th and core PCE inflation on the 28th.
