The Federal Reserve raised interest rates for the first time in more than three years, delivering a quarter-point increase that signals a renewed fight against stubborn inflation and sets up a potential clash with President Donald Trump.

The Federal Open Market Committee voted 12–0 to lift the benchmark federal funds rate to a target range of 3.75% to 4.00%, up from 3.5%–3.75%. It was the first rate hike since July 2023 and the first major policy test for Fed Chair Kevin Warsh, who was nominated by Trump with the expectation he would keep borrowing costs low.

A unanimous vote with a clear message

The unanimous vote sent a clear message: policymakers see inflation as a persistent threat that requires action, even at the risk of political fallout. In a statement after the meeting, the committee said it remains “highly attentive to inflation risks” and signaled that further tightening could be needed if price pressures do not ease.

The decision comes after a string of hot inflation readings, including an August consumer price index that showed core prices rising faster than expected. Energy costs have surged amid the ongoing war with Iran, with Brent crude topping $100 a barrel and feeding through to transport, food and other everyday expenses.

Warsh’s first big move

For Warsh, the hike marks his first major step as Fed chair and a defining moment for his tenure. He has emphasised data dependence and Fed independence, but his appointment by Trump had led many to expect a more dovish approach.

In his press conference, Warsh acknowledged the political sensitivity of the move but stressed that the central bank’s mandate is to ensure price stability and maximum employment over the long term. “Our job is to make sure that inflation does not become entrenched,” he said. “That sometimes means making decisions that are not popular in the short run.”

Analysts said the unanimous vote strengthens Warsh’s hand. A split decision might have suggested internal doubt, but a 12–0 outcome signals broad agreement among policymakers that inflation remains too high to ignore.

Trump’s reaction: public restraint, private frustration

President Trump’s public response was measured. On Wednesday evening, he told reporters he had told Warsh to “do what you want” and said he wanted the Fed “to be independent.” But he also suggested he does not expect Warsh to follow his directions and reiterated his long-standing view that rates should be lower to support growth.

Behind the scenes, allies of the president are said to be frustrated. Trump has repeatedly pressed for rate cuts, arguing that lower borrowing costs would boost business investment, housing and consumer spending. The hike could complicate his economic agenda and feed into broader tensions over the Fed’s autonomy.

What the hike means for households and businesses

The quarter-point increase will gradually feed through to borrowing costs across the economy. Mortgage rates, credit card interest, car loans and business credit are all likely to edge higher, adding to the financial strain on households already dealing with elevated prices.

Housing experts warn that the move reinforces a “higher-for-longer” environment for mortgage rates, which could dampen home sales and construction activity. Trade tensions, the war in the Middle East and heavy spending on AI infrastructure are also expected to keep rates elevated, even if the Fed pauses after this hike.

For businesses, the message is similar: capital will be more expensive, and investment decisions will need to account for a tighter financial environment. Companies that borrowed heavily during the era of near-zero rates may face higher refinancing costs, while those with strong balance sheets could gain a competitive edge.

Markets digest the decision

Financial markets had largely priced in a 25-basis-point increase, so the immediate reaction was muted. Stock indices were little changed in after-hours trading, while Treasury yields held steady. The dollar edged slightly higher against major currencies as traders assessed the Fed’s outlook for future moves.

What investors will be watching closely is the Fed’s “dot plot”, the projection of where each policymaker expects rates to be at the end of this year and in coming years. Any signal that more hikes are on the way could push yields higher and weigh on risk assets.

The road ahead

The Fed’s statement left the door open for further tightening, saying the committee will “carefully assess incoming data” to determine the appropriate stance of policy. With core inflation still above the central bank’s 2% target and energy prices volatile, another hike before year-end cannot be ruled out.

For Warsh, the challenge now is to navigate between two competing pressures: the need to bring inflation under control and the political and economic risks of tightening too much, too fast. His handling of that balance will shape not only the trajectory of the US economy but also the future of the Fed’s independence in an increasingly polarised political environment.

For households and businesses, the message is clear: the era of ultra-low interest rates remains firmly in the past. The cost of money has risen again, and the economy will need to adjust to a new normal in which inflation is taken seriously, even if that means higher rates for longer.
