U.S. stock futures were steady early Tuesday as traders waited on tomorrow’s inflation report.

S&P 500 futures were little changed, Nasdaq 100 futures rose about 0.3%, and Dow futures were roughly flat. The muted tone followed a lower close on Monday and set up a cautious session before Wednesday’s main event: the July Consumer Price Index.

The inflation reading is due from the Bureau of Labor Statistics at 8:30 a.m. ET on Wednesday, August 12. Economists expect headline CPI to rise 0.1% from June and 3.4% from a year earlier, according to consensus estimates. Core CPI, which strips out food and energy, is seen up around 0.3% on the month.

That would mark only a slight cooling from June, when prices actually fell. “The Consumer Price Index for All Urban Consumers ... decreased 0.4 percent on a seasonally adjusted basis in June,” the BLS said in its July 14 release, adding that the all-items index rose 3.5% over the prior 12 months. Core inflation held at 2.6%.

Why this print matters more than usual

The Federal Reserve is not debating a rate cut right now. It is debating a hike.

The Fed left its benchmark at 3.50% to 3.75% on July 29, the fifth straight meeting on hold, and warned that inflation remains “elevated.” With energy prices climbing again, some policymakers have floated tightening at the next meeting on September 16. Wednesday’s CPI is the cleanest read they will get before that decision.

Markets have already dialed back the odds of another move. Futures now imply roughly a 44% chance of a September hike, down from better-than-even odds a week ago, after a shockingly weak July jobs report. Payrolls fell by 23,000 last month against forecasts for an 83,000 gain, and downward revisions erased roughly 146,000 jobs from prior months.

The crosscurrents pulling on the Fed

The backdrop has the hallmarks of stagflation anxiety: a softening labor market on one side, sticky prices on the other.

Oil is the wild card. Brent crude jumped nearly 5% on Monday to about $87.69 a barrel, and WTI settled near $80.42, as the United States and Iran hardened their positions over reopening the Strait of Hormuz. Higher energy costs feed straight into headline inflation and undercut any argument for easing.

Bond traders are taking the threat seriously. The 10-year Treasury yield rose to 4.7% on Monday, its highest level this month. Rising yields lift borrowing costs on mortgages, credit cards and auto loans, and they tend to pressure the high-multiple tech names that have led the market this year. That helps explain why Nasdaq futures edged higher while the broader tape stalled: any hint of cooler inflation would relieve the most rate-sensitive corner of the market first.

What to Watch for the Open

  • July CPI, Wednesday at 8:30 a.m. ET — the core monthly number matters most; a reading above 0.3% would revive hike talk.
  • The 10-year yield — a push past 4.7% signals bond traders are positioning for a hot print.
  • Oil — another leg higher in Brent keeps inflation risk front and center.
  • Fed speakers — any comment on the September meeting could swing rate futures.

Until the number lands, expect thin conviction and choppy, headline-driven trading. Wednesday at 8:30 will decide which way the market exhales.
