US July CPI Matches Forecasts at 3.4% as Core Inflation Cools

The US Consumer Price Index for July 2024 rose 3.4% from a year earlier, matching consensus forecasts, according to data released by the Bureau of Labor Statistics. The monthly CPI increase was 0.1%, also aligning with expectations. A significant development was the cooling in the core CPI, which excludes food and energy, to an annual rate of 2.5% from 2.6% in the prior month. This report provides critical data for the Federal Reserve's deliberations on the path of interest rates for the remainder of the year.

Context — why this matters now

Inflation remains the primary focus for the Federal Reserve as it aims to return price stability to the US economy. The July report arrives after a period of stalled disinflationary progress in the first half of the year. Prior to this release, market participants were keenly watching for signs that the earlier stubbornness in service-sector inflation was abating. The Fed has held its benchmark rate at a restrictive level for nearly a year, aiming to dampen demand without triggering a significant economic downturn. The trajectory of core inflation is particularly critical as it is considered a better gauge of long-term inflationary trends than the more volatile headline figure. The last time core CPI touched 2.5% was in March 2021, marking a return to a level not seen in over three years. This data point is a crucial input for the Federal Open Market Committee's September meeting.

The immediate backdrop for this report included market pricing that indicated uncertainty about the Fed's next move. Financial conditions have tightened slightly in recent weeks, with equity markets showing sensitivity to any inflation surprise. The dollar index has been trading near multi-decade highs, partly on expectations that US interest rates would remain elevated relative to other developed economies. A print significantly above expectations would have reinforced the higher-for-longer narrative, while a substantial miss could have prompted a rapid repricing toward earlier rate cuts. The July data therefore served as a key test of the disinflation narrative.

Data — what the numbers show

The July CPI report showed a clear cooldown in inflationary pressures beneath the surface. The headline year-over-year rate of 3.4% was unchanged from June, but the monthly increase of 0.1% represented a significant slowdown from the prior month's 0.4% decline. The core CPI reading of 2.5% year-over-year edged down from June's 2.6%. On a monthly basis, core prices rose 0.2%, a pickup from the 0.0% reading in the prior month. The unrounded monthly core CPI figure was notably higher than June's -0.017%, indicating a firming of underlying price pressures in July.

Key sub-components revealed a mixed picture. Shelter inflation, a persistent driver, saw owners' equivalent rent and rent of primary residence continue to rise. However, more volatile categories showed significant moves. Energy prices fell dramatically on a monthly basis, down 5.7% after a 9.7% plunge in June, with gasoline leading the decline. Airfares increased by 0.2%, while used car prices fell by 0.2%. Motor vehicle insurance prices dropped 2.0%, a sharp reversal from recent trends. Real average hourly earnings showed a modest year-over-year increase of 0.1%.

Category	July m/m %	June m/m %
Headline CPI	+0.1	-0.4
Core CPI	+0.2	0.0
Shelter	+0.1	+0.1
Energy	-5.7	-9.7

The core services ex-shelter category, a metric closely watched by the Fed, turned positive in July after a -0.089% decline in June. Similarly, core goods prices moved from a -0.086% monthly change to a positive reading. This suggests that the disinflationary impulse from goods prices may be waning, while service price pressures outside of housing remain present but moderated.

Analysis — what it means for markets / sectors / tickers

The immediate market reaction centered on interest rate expectations. Ahead of the report, markets were pricing a 44% probability of a rate hike in September and 24.4 basis points of additional tightening for 2024. The in-line print, coupled with the cooling in the core annual rate, is likely to temper expectations for immediate Fed hawkishness. This environment is generally supportive for growth-oriented sectors of the equity market, particularly technology [XLK] and consumer discretionary [XLY] stocks, which are sensitive to interest rate projections. Lower long-term rates reduce the discount rate on future earnings, boosting valuations.

Conversely, the financial sector [XLF], particularly banks, may face headwinds if the yield curve continues to flatten on reduced hike expectations. Net interest margins for banks often benefit from a steeper yield curve. The cooling inflation data could also pressure the US Dollar Index [DXY], which was strong heading into the release, as it reduces the dollar's interest rate advantage. The USD/JPY pair, trading at 159.04 pre-release, is highly sensitive to US Treasury yield movements. A counter-argument is that the monthly core CPI acceleration to 0.2% from 0.0% suggests underlying inflation is not decelerating rapidly, which could keep the Fed cautiously hawkish. Positioning data suggests that investors had built long dollar positions anticipating a hotter print, leaving room for a short-term reversal.

Outlook — what to watch next

The primary near-term catalyst is the Federal Reserve's Jackson Hole Economic Symposium scheduled for August 22-24. Chair Powell's speech will be scrutinized for any change in tone regarding the inflation outlook and the potential need for further rate hikes. The next Federal Open Market Committee meeting on September 17-18 will be the next official opportunity for a policy shift. Markets will watch for updates to the Summary of Economic Projections, including the dot plot of interest rate expectations.

Key levels to monitor include the 10-year Treasury yield, which will react to changing rate expectations. Resistance for the S&P 500 [SPX] remains near its all-time highs, while support sits at its 50-day moving average. The next crucial inflation data point will be the August CPI report, due for release on September 11. If that report also shows moderating core inflation, it would significantly bolster the case for the Fed to hold rates steady through year-end. The July Personal Consumption Expenditures price index, the Fed's preferred gauge, released on August 30, will provide further confirmation.

Frequently Asked Questions

What does the core CPI tell us that headline CPI does not?

The core Consumer Price Index excludes food and energy prices, which are highly volatile and subject to temporary supply shocks like weather events or geopolitical disruptions. By focusing on core inflation, policymakers and economists aim to discern the underlying, persistent trend in inflation. The Federal Reserve pays close attention to core measures because they provide a clearer signal of where inflation is headed over the medium term, independent of short-term noise. The July core CPI cooling to 2.5% suggests that the broader disinflationary process, while slow, is still intact.

How does this inflation report affect mortgage rates?

Mortgage rates are primarily influenced by the yield on the 10-year US Treasury note, which in turn reacts to inflation data and Federal Reserve policy expectations. A cooler-than-expected inflation report typically leads to lower Treasury yields, which can translate into lower mortgage rates. Conversely, hot inflation data pushes yields and mortgage costs higher. The July CPI report, being in-line with expectations and showing a modest cooling in the core rate, is unlikely to cause a dramatic spike in mortgage rates and may provide some stability or modest relief if the trend continues.
