What is the US Federal Reserve and why does its interest rate decision matter?

The Federal Reserve held US interest rates steady at between 3.5% and 3.75% in June 2026, but signalled that a rate hike could come before the end of the year. The decision, taken under new chair Kevin Warsh, sent shockwaves through financial markets and raised questions about the direction of the world's most powerful central bank.

The Fed, formally the Federal Reserve System, is the central bank of the United States. Its main job is to manage the country's monetary policy – the levers that influence how much it costs to borrow money and how fast prices rise across the economy. It does this primarily by setting a target for the federal funds rate, the interest rate at which banks lend to each other overnight. That rate ripples out to affect everything from mortgage rates to credit card interest to the returns on savings accounts. The Fed's policy-making arm, the Federal Open Market Committee (FOMC), meets roughly every six weeks to decide whether to raise, lower or hold that target rate.

At its June meeting – the first chaired by Warsh, who took over in May after being nominated by President Donald Trump – the FOMC voted unanimously to keep the rate where it had been since December 2025. But the accompanying “dot-plot” grid, which shows each official's projection for future rates, revealed a sharp shift: nine of the 18 participants predicted at least one rate increase this year, while only one expected a cut. The remaining eight saw rates staying put. That was a U-turn from March, when 12 of 19 officials had projected a cut by year end. The change was driven by inflation, which stood at an above-target 3.8%, partly due to supply shocks from the US-Israel war in Iran. Warsh, who opposes the dot-plot but allowed it to continue, described the committee as united in its goal of bringing inflation back to the Fed's 2% target. “The Committee will deliver price stability,” the new, drastically shortened statement concluded.

For UK readers, the Fed’s decisions matter because the dollar is the world's reserve currency. When US interest rates rise, the dollar tends to strengthen, which can make imports from the US cheaper for British consumers but also pushes up the cost of goods priced in dollars, like oil and many commodities. Higher US rates can also draw investment away from the UK, putting downward pressure on the pound. Moreover, the Bank of England often takes its cue from the Fed: if the Fed hikes, it becomes easier for the Bank to raise its own rates to tame inflation without worrying about weakening the pound too much. UK mortgage holders, already squeezed by high borrowing costs, should pay close attention to the Fed's next moves.

Q: How does the Federal Reserve decide interest rates? The FOMC, which includes seven Fed board members and five of the 12 regional bank presidents, votes on the target range for the federal funds rate. They consider economic data such as inflation, employment, and growth, as well as global risks. Each member submits their own rate projections, published as the “dot-plot,” but the final decision is by majority vote. At the June 2026 meeting, the vote was unanimous for holding rates.

Q: Why is the Fed's new chair, Kevin Warsh, significant? Warsh was appointed by President Trump after publicly criticising his predecessor Jerome Powell. He has pledged to overhaul the Fed's communications, arguing it should say less and act more. His first statement was just 132 words, down from roughly 350 in April. He also created five taskforces to assess monetary policy conduct, including one dedicated to communications. He did not submit his own dot-plot projection, which he opposes.

Q: What is the “dot-plot” and why does it matter? The dot-plot is a grid showing where each FOMC participant thinks the federal funds rate will end in the current and future years. It gives markets a window into the committee's thinking, though it is not a commitment. In March 2026, the median dot pointed to cuts; in June it pointed to possible hikes. This shift caused US stocks to fall, with the Dow dropping 500 points on the day of the announcement.

What happens next: The Fed's next scheduled meeting is in late July 2026. Markets will be watching closely for any change in the rate stance. Warsh has said the new taskforces will report in the autumn. The path of inflation, particularly if the Iran conflict escalates or eases, will be a major factor. In the UK, the Bank of England's Monetary Policy Committee will also be watching, with its next decision expected in August. For now, the message from Washington is clear: the era of cheap money is over, and the fight against inflation is not yet won.
