Hot September CPI Puts October Fed Hike Back on the Table

September CPI Lands Hot Across the Board, Repricing the Fed Path

US consumer prices for September came in above every major consensus estimate, forcing a rapid reassessment of where the Federal Reserve goes next. Headline CPI rose 0.6% month-on-month and 3.7% year-on-year, against a Dow Jones consensus of 3.6%, while core — which strips out food and energy — printed 0.3% month-on-month and 2.6% year-on-year, both above the 0.2% and 2.5% expected. The unrounded figures were 0.649% on the headline and 0.335% on core, leaving little room to argue the beat was marginal.

Gasoline was the single largest driver, accounting for more than half the monthly gain. That matters for the headline but less for the Fed's reaction function. The more consequential detail was the core reading: analysis from Carson Group noted it ran at a 3.7% annualised pace, a figure that sits well above the Fed's target and complicates any argument that the September hike cycle has done enough.

Markets moved swiftly. Odds of a 25 basis point hike at the 28 October FOMC meeting rose to around 46% from roughly 20% before the release, according to Bloomberg and LSEG data. Short-dated Treasuries came under pressure, the dollar strengthened, and gold retreated. US equities sold off, with the Russell 2000 and Nasdaq each falling around 2%. European stocks, by contrast, held up through the session — a divergence that may reflect the different rate trajectories priced across the Atlantic.

The Fed's last move was a unanimous 25 basis point hike on 16 September, the first since July 2023 under Chair Kevin Warsh, which brought the funds rate to 3.75–4.00%. October had looked like a pause after September payrolls came in sharply below expectations, but the CPI data has reopened that debate. The Fed blackout period begins on 17 October, meaning officials have a narrow window to shape expectations before going silent ahead of the 27–28 October meeting.

Most banks had been positioned for a December hike rather than an October move. BofA is an exception, expecting tightening at both meetings. The September CPI print does not settle the question, but it narrows the distance between those two camps.

Energy Costs and European Gas Add to the Inflation Backdrop

Dutch TTF front-month gas reached its highest level since December 2022 on 13 October, extending a run of consecutive daily gains amid Middle East tensions and below-seasonal European storage levels. Rising gas costs are feeding into euro-area inflation expectations ahead of the ECB's 28–29 October meeting, where market pricing currently leans heavily toward a hold despite the energy pressure.

In oil markets, the EIA weekly petroleum report — delayed by the Columbus Day holiday — is scheduled for 16:00 UTC today. The API survey showed a large crude draw for the week to 9 October, and Brent has held above the $100 level. A draw near the API figure in the official data could add to energy-driven inflation concerns that are already front of mind after the CPI print.

PPI and Retail Sales at 12:30 UTC Are the Immediate Test

US September producer prices and retail sales are both scheduled for 12:30 UTC today. Forecasts cited by CNBC put PPI above August on both a monthly and annual basis. A reading that matches or exceeds those expectations could extend the selloff in front-end Treasuries and lend further support to the dollar, keeping October hike odds elevated. A softer outcome may give the bond market some relief, though the core CPI beat from 14 October will not be easily set aside.

The FOMC decision on 28 October is the next major event on the calendar. With the blackout beginning 17 October, today's data may be among the last inputs officials can publicly react to before the meeting.
