What happened

The Federal Open Market Committee voted 12 to 0 to raise the target range for the federal funds rate by 25 basis points to 3.75% to 4%, its first increase since July 2023. The move brought the overnight rate up from a 3.5% to 3.75% range.

In its statement, the committee said economic activity was expanding at a solid pace and that domestic spending had been resilient, while "inflation remains elevated". It added that the action would "support a timelier return to the Committee's 2 percent goal" and that it would "deliver price stability".

At his news conference, Chair Kevin Warsh said inflation had been "too high ... for too long" and that recent readings did not show underlying trends had meaningfully improved. He cited a strong labour market, elevated inflation and tension in the Middle East as reasons for what he called a "firm unanimous decision". Updated projections point to the possibility of one more increase this year, with no hikes penciled in for subsequent years.

The context

The hike had been widely anticipated, with markets pricing in a better than 90% chance ahead of the meeting, according to CME FedWatch. The shift followed hotter data: consumer prices rose 0.4% in August, up 3.4% year on year, while surging oil prices, driven by the US-Iran war, fed through to fuel costs. Brent crude hovered near $109 a barrel and the average price of a gallon of petrol reached $4.36.

The rationale was unusual. The Fed typically looks through supply-driven inflation of this kind, but officials weighed the risk that persistent energy prices could lift inflation expectations, with the earlier "transitory" episode still fresh in policymakers' minds. In July, three members had already dissented in favour of a hike.

Why it matters

The decision reasserts the central bank's independence at a politically charged moment, weeks before the US midterm elections. President Trump, who had demanded cuts and criticised the board, posted on Truth Social that rates "should be 1%, or less" and later said he retained confidence in Warsh while calling the board "very tough".

The 10-year Treasury yield, a benchmark for mortgage and car-loan costs, climbed back above 5% to about 5.016% after the decision and Warsh's remarks, having hit a multi-decade high on Tuesday. A 30-year fixed-rate mortgage had risen to 7.19%. Higher borrowing costs across the curve tighten conditions for households and businesses at a time when growth remains solid but prices are sticky.

What to watch

Officials' projections signal the possibility of a further hike this year, though the Fed is expected to skip the October meeting given its proximity to the elections. Goldman Sachs Asset Management's Kay Haigh said one more hike in December was the base case, "contingent on upcoming CPI reports and the path of energy prices".

Investors will track inflation data, oil prices tied to the US-Iran war, and any further friction between the White House and the Fed. The dot-plot showed no increases in subsequent years, with one cut each indicated for 2028 and 2029, and no return to the 2% target expected until 2029.
