The PCE Moment: Why Today's Inflation Data Could Decide the Fed's Next Move
There is a number that Wall Street has been dreading for weeks: 3.7. That is how many percent the Personal Consumption Expenditures price index rose in June on a year-over-year basis - the Fed's own preferred inflation gauge, running nearly double its 2 percent target. Today, August 26, the Bureau of Economic Analysis releases the July PCE report. The number that comes out this morning will land at the intersection of three of the most consequential market events of the week: Nvidia's earnings after the bell, the opening of the Jackson Hole symposium on Thursday, and a Federal Reserve that is, for the first time in years, genuinely debating whether to raise rates rather than cut them.
The stakes are not abstract. Three Federal Open Market Committee members voted for a rate hike at the July meeting. The funds rate sits at 3.50 to 3.75 percent - unchanged for five consecutive meetings. Inflation has exceeded the Fed's 2 percent target for more than five consecutive years. And Kevin Warsh, the new Fed chair appointed by President Trump, is scheduled to deliver his first major policy address at Jackson Hole on August 28 - a speech the market has been treating as a blank piece of paper that could be filled with almost anything.
What the Data Is Expected to Show
Consensus forecasts heading into today's release call for headline PCE to come in at approximately 3.6 percent year-over-year in July, down slightly from 3.7 percent in June. Core PCE - which strips out food and energy and is the number the Fed watches most closely - is expected to print at around 3.2 percent, down from 3.3 percent in June. Month-over-month, headline PCE is forecast to rise 0.07 percent after declining 0.11 percent in June, while core is expected to rise 0.18 percent.
On the surface, those numbers look like modest progress. But the context matters enormously. A 3.2 percent core PCE reading is not a number that gives a central bank permission to cut rates. It is a number that keeps the rate hike debate alive. The Cleveland Fed's inflation nowcasting model, updated through August 25, projects July PCE at approximately 3.65 percent year-over-year and core PCE at 3.29 percent - broadly in line with consensus but still well above target.
Why This Print Is Different From the Last Several
The July CPI report, released on August 12, offered what Schwab's analysts called "a reprieve, not an all-clear." Headline CPI came in at 3.4 percent year-over-year, down from 3.5 percent in June. Core CPI printed at 2.5 percent. The market read that as a sign that the September rate hike probability could stay contained - and indeed, CME FedWatch data showed the September hike probability dropping to around 35 percent following the CPI release.
But PCE and CPI are not the same index. PCE gives more weight to healthcare and less weight to shelter than CPI does. In July, healthcare costs were a notable driver of CPI upside - medical care rose 0.4 percent month-over-month, hospital services jumped 0.5 percent. PCE's broader healthcare gauge will capture more of that pressure. Meanwhile, computer software and accessories - a category that accounts for a larger share of core PCE than core CPI - rose 0.5 percent month-over-month and 21 percent year-over-year in July, driven by AI-related spending. That category alone could push the PCE reading above what the CPI implied.
The result is a genuine possibility that today's PCE print comes in hotter than the CPI suggested - and hotter than the market has priced. If core PCE surprises to the upside, the September rate hike probability, currently sitting at 35 percent, could move sharply higher before Warsh even takes the podium at Jackson Hole.
The Warsh Variable
The Jackson Hole speech on August 28 is the event that gives today's PCE data its full weight. Warsh has been deliberately opaque about his policy intentions since taking office in May. He stripped most forward guidance from the Fed's July statement. He told reporters at the post-meeting press conference that he viewed Jackson Hole as "a blank piece of paper" and wanted to focus on "big questions." That framing has left the market guessing about whether he is preparing to signal a rate hike, defend the current hold, or use the speech to reframe the Fed's entire communication strategy.
What is not ambiguous is the political context. President Trump has made clear he wants lower interest rates. Warsh, his appointee, is navigating a board where nine members penciled in at least one rate hike this year and six see at least two. The tension between the White House's preference and the FOMC's internal arithmetic is real - and the bond market is watching. The 30-year Treasury yield has been trading near 5.25 percent, its highest level since 2007. A hot PCE print today, followed by a hawkish Warsh speech on Thursday, would be a combination that tests the equity market's assumption that the Fed will eventually find a reason to ease.
The Nvidia Complication
The timing of today's PCE release alongside Nvidia's Q2 FY2027 earnings - expected after the bell - creates an unusual macro-micro collision. Consensus calls for Nvidia to report approximately $92 billion in quarterly revenue, nearly double a year earlier, with adjusted earnings per share of around $2.09. The AI capital expenditure cycle that has driven those numbers is also, paradoxically, one of the forces keeping inflation elevated. Computer hardware and software prices tied to AI infrastructure have been rising sharply - the same dynamic that is showing up in the PCE data today.
If Nvidia beats and guides higher, it validates the AI buildout thesis and supports the equity market's current valuation. But it also reinforces the inflationary pressure embedded in the technology sector's spending surge. The market will have to hold two contradictory ideas simultaneously: AI is good for earnings, and AI-driven spending is one of the reasons the Fed cannot cut rates.
What Investors Should Watch
The number that matters most in today's PCE release is not the headline. It is the month-over-month core reading. A print above 0.25 percent month-over-month would be difficult to dismiss as noise - it would represent an annualized pace of 3 percent or higher, well above target, and would almost certainly push September rate hike odds above 50 percent before the open. A print at or below 0.15 percent would give the market breathing room and likely keep the September hike as a tail risk rather than a base case.
The personal income and spending data released alongside PCE will also matter. Real consumer spending jumped 3.2 percent annualized in Q2. If July spending data shows continued strength, it complicates the narrative that demand is cooling enough to bring inflation down without a rate hike. A strong consumer combined with sticky inflation is the configuration that makes the Fed's job hardest - and the market's job of pricing equities most uncertain.
Today is one of those days when the macro and the micro arrive at the same time, and the answer to one question changes the meaning of the other. The PCE number lands first. Everything else follows from there.
