CPI Tops Estimates, Fed Hike Odds Jump to 90% as Trump's $5,000 Dividend Pledge Adds Fiscal Wildcard

Key Takeaways:

• August CPI rose 3.4% year-over-year and 0.4% on the month, with core inflation accelerating to 0.3%, hotter than economists expected on both counts.
• The odds of a Fed rate hike at next week's meeting jumped to around 90%, up sharply from roughly 70% just a day earlier, according to CME FedWatch.
• The inflation news lands alongside President Trump's pledge of $5,000 dividend checks to every US adult if Republicans hold Congress in the midterms, a promise budget analysts say could cost over $1.2 trillion and add further pressure to an already stretched deficit.

Market Summary:

Friday's Consumer Price Index report gave markets little room to hope for a cooling trend. Headline inflation rose 3.4% year-over-year, matching July's pace but coming in hotter than the 3.3% economists had forecast, while the monthly gain accelerated to 0.4% from July's 0.1%. Core CPI, which strips out volatile food and energy prices, held at 2.4% annually but rose 0.3% on the month, beating the expected 0.2% gain. Gasoline did much of the damage, jumping 3.9% for the month and now up 27.4% from a year ago, with prices at the pump averaging over $4.28 a gallon as the Iran conflict keeps oil elevated above $100 a barrel.

The market reaction was immediate. Odds of a Fed hike at next week's meeting surged to around 90%, up from roughly 70% the day before the report, according to CME FedWatch, which would mark the Fed's first rate increase in more than three years. Economists were blunt about what it means: several noted the upside surprise in core prices all but locks in a move next week, with some already penciling in a second hike in December. Equities actually rose on the news, a sign traders see the hike as priced in and largely a formality at this point, though the broader concern is that this data was captured before the recent spike in oil and diesel prices, meaning September's report could look even hotter.

Layered on top of the inflation picture is a fiscal wildcard that's drawing its own scrutiny. At the Republican National Convention in Dallas, President Trump pledged a $5,000 dividend check to every adult American if Republicans keep control of the House and Senate in the midterms, an idea Vice President JD Vance has tied to tariff revenue. Independent estimates put the cost of sending that payment to roughly 250 million eligible adults at over $1.2 trillion, a sum that dwarfs the roughly $125 billion in net tariff revenue the government is expected to collect and would land on top of a deficit already projected near $1.9 trillion for the fiscal year. The proposal has drawn criticism from economists and lawmakers on both sides over both its cost and its structure, since tying a payout explicitly to an election outcome has raised separate legal questions. For markets, the pledge is still theoretical and unfunded, but it adds another layer of fiscal uncertainty at a moment when the Fed is already wrestling with sticky inflation and near-decade-high bond yields.
