Core goods helped US CPI in May – but don’t expect it to last

With the 90-day pause still in effect and ongoing China negotiations, we will re-iterate (for a third consecutive month) that the impact of tariffs was not expected to show up in the CPI data and largely this proved true in May. Indeed, this morning’s downside surprise to core (up 0.1% m/m, below market expectations of +0.2% m/m) confirmed our hypothesis. In May, a continued moderation in shelter prices and declines in both new and used autos underpinned this favorable inflation reading and meant core goods prices were flat. But the relief in the goods space will likely be temporary. We expect inflation to peak above 3% later this year if current trade policy remains status quo. At +2.8% y/y, core inflation remains uncomfortably high ahead of the risk of full tariff passthrough to core goods prices (which we expect will take a few months). Still, May’s print may provide the Fed with more flexibility to cut in the months ahead if they continue to observe weakness in the labor market.

With a focus on today’s data, here’s what stood out to us: 

  • Headline was below expectations at 0.1% m/m and left y/y price growth at 2.4%. As expected, we saw upward pressure on food prices (+0.3% m/m) after the USDA Farmer prices paid index shot up in May. But energy commodities were down significantly, motor fuel fell nearly 3% m/m alongside weaker natural gas prices. 

  • Core inflation came in below consensus (up +0.1% m/m vs consensus +0.2% m/m) which helped year-over-year core inflation hold steady at 2.8%. Yet again, core services price growth exceeded core goods (unchanged). 

  • Interestingly, where we did see upward pressure was in motor vehicle parts and equipment (+0.93% m/m). It’s too soon to know for sure, but this could be an early indication of steel and aluminum tariffs weighing on inputs. Tariffs will impact parts and equipment before we see pressure on finished new motor vehicles. But weak demand for autos in May was reflected in declines for new and used motor vehicle prices – and that helped offset rises elsewhere in the core goods space. 

  • Zooming in on services, we saw weaker rent and OER prints this month and a fourth month of significant deflation from airfares (-2.7% m/m). Weaker airfares are likely reflective of cheaper jet fuel, but we are watching closely for indication of weakening demand for discretionary services. We have yet to see any indication that this is happening, as restaurant spending remains robust.

  • This month’s downside surprised markets amidst tariff fears. While this may have temporarily calmed markets, households are still grappling with the after-effects of significant inflation over the past five years. Since the pandemic, prices have risen ~25% with wages only surpassing price growth by a small margin (+27%). This will continue to impact low-and-middle-income US consumers and underpins a key theme that we have been witnessing- “soft” (survey) data has diverged from “hard” macro data.

  • Looking at our diffusion index, we are seeing more CPI basket items moving into the +3-5% y/y price growth category from >+5% y/y. While this is a positive development, the share of basket items reporting price growth above 3% still eclipses the pre-pandemic status quo.

The Bottom Line:

  • Core CPI moderated in February, in-line with our expectations and proving that seasonal spikes were a January effect this year. February data indicated that inflation expectations in consumer surveys were overblown. But this divergence highlights a key yellow flag emerging in the US economy – a divergence between “soft” sentiment data and hard data.

  • The pace of core services halved relative to a month ago and a sizable decline in airfares contributed to this. We are watching demand for travel as a leading indicator of higher-income households paring back spending. Hotel prices also moderated this month suggesting travel demand is fading.

  • Additionally, we have witnessed a spike in year-over-year used car prices in contrast to the continued declines in prices for new cars. We are watching closely to see if the recent retracement on the stock market results in a pullback from high-income consumers.

  • Still, this morning’s data adds to our conviction that the Fed will keep rates on hold at next week’s meeting as the y/y pace of core inflation remained elevated at 3.1% and the unemployment rate remained low at 4.1%. But a moderation in inflationary pressures alongside a softer trajectory for employment data (thanks to DOGE layoffs and education hiring freezes) shifts the balance of risks, providing a potential cutting bias if the labor market continues to weaken.

The Details:

  • February’s US CPI data suggests that the Q1 bump was largely contained in January. Core CPI moderated (+0.2% MoM) after a January spike attributed to seasonality. Year-over-year core inflation moved down to 3.1%, in-line with our expectations.

  • Headline inflation surprised to the downside, up only 0.2% month-over-month with year-over-year price growth moving lower to 2.8% (from 3.0% in January).

  • The pressure came off for core goods (+0.2% MoM) and services (+0.25%). Used auto prices and automotive services are still elevated but moved meaningfully lower in February. The retracement in core services (which halved between January and February) was assisted by a drop in airfares (down -4% from January), thanks to lower fuel costs but also likely due to a drop in demand for travel.

  • Both rents and owners’ equivalents held steady at a modest pace (+0.3% MoM) and accounted for roughly half of the month-over-month increase in headline.

  • In January, we noted a rise in the breadth of inflationary pressures. This month, the trend reversed. As of February, roughly 29% of CPI basket items reported price growth above 5%, compared to 33% in February 2024 and 45% in January 2025.

By Carrie Freestone and Mike Reid

The Bottom Line:

  • Core CPI’s upside surprise was another reflection of the “January effect”- seasonality strikes again! Even still, if the FOMC was not in a further easing mindset before, this morning’s data release will not incentivize them to move from the sidelines.

  • More importantly, today’s print was one of many upside surprises to the economic data in recent months- following two successive moves lower in the unemployment rate.

  • Our expectation is for the Fed to hold rates at 4.25% to 4.5% through the year, and January’s CPI numbers add to that conviction. At the January FOMC meeting, Chair Powell emphasized that the Fed remains data dependent. Still, he acknowledged we are in a “fatter tails” scenario where the odds of a shock to the economy are wider. It is still too premature for the impact of tariff announcements to show up in core goods, but we will be watching in the coming months. Over the longer-term, a structural shift will become more problematic- tighter labour market thanks to higher retirements and stringent immigration policies, which will exert upward pressure on wages.

  • While headline inflation is sitting at 3.0%, it still feels like 3.2% for lower income households. This disparity will continue to be an important story in a higher-rate environment, as lower-income earners become more dependent on debt to sustain spending. The $40.8 billion increase in consumer credit outstanding in December (the largest month-over-month increase in season history) could be a growing sign of higher prices weighing on lower-income consumers.

The Details:

  • U.S. headline CPI growth surprised markets- proving the “January effect” is still alive and well. Headline moved up 0.5% m/m January on a seasonally-adjusted basis, with year-over-year growth ticking up to 3.0 % exceeding market expectations (and our own).

  • Core CPI moved notably higher, up 0.4% on a month-over-month basis, with year-over-year core price growth up by one-tenth to 3.3%.

  • Shelter price growth moved up 0.4% month-over-month, driven primarily by a spike in lodging away from home. The one bright spot of today’s report was the more modest 0.3% increases for both rents and owners’ equivalents. Growth in shelter costs is still accounting for just under half of total year-over-year price growth.

  • The breadth of inflationary pressured widened significantly – currently ~38% of the U.S. CPI basket (excluding shelter) is reporting price growth above 5%- the highest share since mid-2023 and up significantly from 28% in December. At the same time, the share of basket items reporting price growth below 1% also moved significantly higher, suggesting a concerning divergence among products.

  • The Fed’s super-core measure moved higher, to 0.8% from 0.2% in December, with the 3-month moving average annualized growth rate sitting at a higher 5.3%, up meaningfully from December’s 3.3%.

  • Recent tariff announcements were not expected to show up in core goods prices just yet- still, core goods rose by 0.3% relative to December- this was the highest increase in over one year.

By Nathan Janzen and Abbey Xu

The Bottom Line:

  • The tick lower in core price growth in December follows a string of upside surprises and shouldn’t be enough to justify another Federal Reserve rate cut later this month. Inflation has still slowed from where it was a year ago, but evidence has mounted that the persistent run of U.S. economic growth outperformance is also limiting the pace of slowing in inflation.

  • We continue to expect the Fed will need to keep interest rates higher for longer than other regions to offset the inflationary impact of a resilient economy and large government budget deficit for this point in the economic cycle, and do not expect the Fed to cut the fed funds target range further this year.

The Details:

  • U.S. headline CPI growth edged up to 2.9% – its highest level since July – but with the pickup from a 2.7% rate in November largely due to a smaller year-over-year decline in the volatile energy component.

  • Core (ex-food & energy) price growth edged down to 3.2% from 3.3% in each of the three prior months on 0.2% month-over-month increase from November.

  • Growth in home rents is still accounting for more than half of total year-over-year price growth, but continued to show signs of slowing with the bulky owner’s equivalent rent component up 0.3% month-over-month in December and the year-over-year rate ticking down to 4.8%.

  • More worrying in recent months have been signs of a broader reacceleration in price pressures — but most of those measures looked better in December.

  • Core services ex-rent prices (Fed’s so-called super-core) edged up 0.2%, its smallest month-over-month increase since July and pushing the 3-month average growth rate down to an annualized 3.5%.

  • Core goods prices edged up 0.1% despite a 0.5% rise in new vehicle prices. Prices for appliances plunged 2.9% month-over-month and clothing prices were little changed.

  • The breadth of inflation over the last 3 months narrowed slightly – by our count 55% of the consumer basket ex-shelter was rising at a 3% or more annualized rate over the last three months, down from 61% in November, but still up from below 30% in Q3 of last year.

By Nathan Janzen and Abbey Xu

The Bottom Line:

  • The November CPI report showed headline inflation was largely in line with expectations. Both core ex-food & energy and the Fed’s preferred core measure remained sticky. Still, persistent inflationary pressures came from sectors like services and housing.

  • Inflation has still slowed from where it was earlier this year and, combined with gentle softening in labour markets (unemployment rate edging higher, job openings lower) supports the view that current interest rates are still higher than needed to achieve the Fed’s 2% target sustainably. We maintain our base-case projection for 25 basis point rate cuts in December and January, but to pause at those levels for the rest of 2025 with interest rates expected to need to stay high to offset the inflationary impact of a resilient economy and large government budget deficit.

The Details:

  • U.S. headline CPI growth increased marginally in November, with the year-over-year rate climbing to 2.7% from 2.6% in October, driven primarily by a slower pace of energy price declines.

  • Food prices showed a slight pickup in momentum, rising 2.4% from a year ago, up from 2.1% in October, though remaining well below the elevated rates seen in 2022.

  • Core inflation (excluding food and energy) remained stable at 3.3% year-over-year for the third straight month, suggesting some stickiness in underlying price pressures.

  • The Fed’s closely-watched “super-core” measure (core services ex-home rents) remained elevated, with the 3-month rolling average holding steady at an annualized 4.3%.

  • The breadth of inflation pressures across non-shelter components widened in November, with the share of the CPI basket growing at above a 3% annualized rate over the last three months rising to 63% from 49% in October.

  • The housing components cooled in November, with shelter costs up 4.7% year-over-year versus 4.9% in the prior month. While shelter component continued to account for a significant portion of core inflation, market indicators suggest this pressure should gradually ease as new lease rates flow through to CPI rent calculations.

By Nathan Janzen and Abbey Xu

The Bottom Line:

  • The October CPI data was broadly as-expected and shouldn’t prevent another cut in interest rates from the Federal Reserve in December.

  • Inflation has still slowed from where it was earlier this year, and (gradually) softening labour markets argue interest rates are higher than they need to be to get price growth fully and sustainably back to the Fed’s 2% objective even with a resilient U.S. economy and the inflationary impact of a large government budget deficit.

  • The Federal reserve is still highly data dependent and will see another month of inflation and labour market data before the next policy decision in December. Our own base-case projections expect 25 basis point rate cuts to the fed funds range in December and January, and then a pause for the rest of 2025 at a 4% to 4.25% range.

The Details:

  • U.S. price growth came in largely as expected in October with a 0.2% increase in headline CPI growth pushing the year-over-year rate up to 2.6% from 2.4% in September.

  • Core (ex-food & energy) price growth also edged higher, up (a still larger than “usual”) 0.3% from October and 3.3% from a year ago.

  • Two-thirds of year-over-year core price growth is still coming from the bulky home rent components, and growth in those will fade as slower growth in market rent prices flows through to CPI growth with a lag as leases are renewed.

  • Still, by our count, the breadth of inflation pressures across non-shelter components also widened. By our count, the share of the CPI basket excluding shelter with price growth above a 3% annualized rate over the last three months rose to just under 50% in October. That is still well-below levels closer to 90% in 2022, but up from below 30% over the summer.

  • The 3-month rolling average increase in the Fed’s “super-core” (core services ex-home rents) accelerated to an annualized 4.3% and the year-over-year rate of increase ticked up to 4.4% from 4.3% in September.

  • Core goods prices were little changed after rising 0.2% in September, and were still down 1.2% from a year ago.

By Nathan Janzen and Abbey Xu

  • U.S. price growth surprised broadly on the upside in September – year-over-year CPI growth ticked down less than expected (to 2.4% from 2.5%) on broadly firmer month-over-month increases across subcomponents.

  • Ex-food & energy price growth edged higher (on a year-over-year basis) for the first time since March 2023, on a second consecutive larger than ‘normal’ 0.3% month-over-month increase.

  • Unlike in August, when core price growth was driven largely by an increase in the bulky home rent component, the September gain was relatively broadly based.

  • The Fed’s ‘supercore’ (core services ex-shelter) prices rose 0.4% month-over-month in September – the largest increase since April. That followed a 0.3% jump in August and pushed the 3-month rolling average growth rate to an annualized 3.8%.

  • And core goods prices rose for the first time since February (+0.2% month-over-month).

  • The breadth of the CPI basket seeing larger than normal price growth is still narrower than it was earlier this year, but widened in September. The share of the CPI basket (excluding the large shelter component) with price growth above a 3% annualized rate over the last three months jumped to 33% in September from 22% in August (although still below the average 45% share over the first half of 2024).

Bottom line: The (small) upward surprise in September price growth isn’t likely enough to prevent the Fed from following through with additional interest rate cuts, but further lowers odds of a repeat September’s 50 bp reduction that already fell dramatically after September’s strong payroll report last week. We continue to expect, as a base-case, that broader inflation pressures will continue to ease as a gradual softening in labour markets continues (the spike higher in initial jobless claims separately reported this morning was likely distorted by the impact of hurricanes and strikes). But stickier inflation readings over the last two months and resilient labour markets to-date are consistent with our expectation for a gradual and limited additional fed rate cutting cycle into next year (just three additional 25 basis point cuts assumed per Fed meeting into January of 2025)

Price pressures remained narrow, with over 50% of the CPI basket growing at rate less than 1%.

Fed’s preferred core measure accelerated in September.

Headline CPI edged lower to 2.4% as energy prices drop lower in September.

Wage growth continues to broadly trend lower in the U.S.

By Nathan Janzen and Abbey Xu

  • Headline CPI growth edged down to 2.5% in August after dipping below 3% (2.9%) for the first time since March 2021 in July alongside underlying details that also point to further easing in broader inflation pressures.

  • The slower year-over-year growth came almost entirely from lower energy prices. Food price growth was little changed (2.1% from a year ago) and core (ex-food & energy) price growth surprised (slightly) on the upside with a 0.3% month-over-month increase that was the biggest since April.

  • But the upward surprise in core prices was not broadly-based Much of the increase came from a 0.5% jump the bulky owners’ equivalent rent component that won’t likely be repeated in months ahead as broader trends in rent price growth remain slower. And airfares jumped 3.9% from July.

  • Outside of the large shelter component, the breadth of price pressures continues to narrow. By our count, the share of the CPI basket growing at a rate above 3% annualized rate over the last 3 months dropped to 21% from 25% in July, and the share of the basket with price growth below 1% has jumped to 63%.

  • The Fed’s preferred ‘supercore’ (core services ex-rent) measure also ticked higher in August, but softer earlier leadings left the 3-month rolling average at a still relatively low 1.9% annualized rate.

Bottom line: While most of the pullback in year-over-year CPI growth in August came from the volatile energy component, underlying details continue to point to softening broader price growth trends. And a gradual updrift in the unemployment rate should signal to monetary policymakers that inflation will continue to drift lower rather than higher. The small upward surprise in core price growth reduces the odds (which we already thought were quite low) of a larger-than-normal 50 basis point interest rate cut from the Fed later this month but should do nothing to dissuade the central bank from kicking off a gradual easing cycle with a 25 reduction.

Headline inflation edged lower to 2.5% year-over-year on slower energy price growth

The breadth of inflation pressure remained narrow, with more than 60% of the CPI basket with inflation (on a three-month annualize basis) at less than 1%

Fed’s closely watched core services ex-shelter inflation measure ticked higher but was still below the 2% target on an annualized three-month rolling basis

Grocery inflation continued to drop, and has returned back to pre-pandemic levels

Lower ratio of vacancies to unemployment means very little slack in the labour market, and downward pressure on wage growth moving forward

By Nathan Janzen and Abbey Xu

  • Headline CPI growth edged down to 2.9% in July (the lowest since March 2021) from 3.0% in June and with further signs that underlying inflation trends continue to slow after a worrying reacceleration earlier this year.

  • The Fed’s closely watched ‘supercore’ (core services excluding home rents) rose a ‘normal’ looking 0.2% month-over-month after consecutive downside surprises in the prior two months. The 3-month annualized increase in the measure slowed to just 0.5%, the lowest since a sharp price pullback during the pandemic.

  • The breadth of price pressures continues to narrow – by our count, the share of the CPI basket (excluding shelter) growing at a rate above a 3% annualized rate over the last 3 months dropped to 25% in July, down from 31% in June and below the 29% pre-pandemic average in 2019.

  • Excluding food and energy products, core CPI growth is still elevated at 3.2% year-over-year, but down from 3.3% in June and with a disproportionate share of the increase coming from high price growth in home rents. Those rent price increases are expected to continue to broadly slow as smaller increases in current market rents filter through to leases with a lag.

  • Year-over-year energy and food price growth were both little changed in July (1.1% and 2.2%, respectively)

Bottom line: The U.S. economic backdrop isn’t collapsing in a way that would force the Federal Reserve to panic. But a gradual rise in the unemployment rate is increasing the odds that wage growth and inflation will continue to drift lower, and interest rates are still at levels well above the Fed’s estimate of long-run neutral. The Fed will still get another jobs and inflation report ahead of the next scheduled interest rate decision in September, but we continue to look for a 25 basis point rate cut at that meeting and think risks of a larger 50 basis point reduction would be contingent on a significantly more pronounced (and unexpected) deterioration in labour market data for August.

Headline inflation dipped to 2.9% year-over-year, primarily due to slower price growth in core goods

The Fed’s preferred core measure decreased again on a 3-month rolling average basis.

Inflationary pressures remained narrow compared to pre-pandemic levels.

Rent inflation trended lower in recent months, consistent with the slower growth in market rents observed previously.

Market-based estimates of future price inflation fell below the 2% target, suggesting that price growth is likely to continue slowing in the U.S.
