Consumer prices in the United States rose 0.4% in October, faster than the 0.3% increase analysts had expected, according to figures from the Bureau of Labor Statistics. The result lands just a week after midterm elections that were fought largely over the cost of living and strengthens the case for the Federal Reserve to raise interest rates at its December meeting. The monthly rise was lower than the 0.6% recorded in September, but the surprise to the upside has changed the mood. The bureau did not publish its usual 12-month figure because it did not collect data in October 2025.
Those who see the data as a warning point to the persistence of price pressures. October's increase was driven by housing, food and energy costs, and it exceeded what forecasters had predicted. Federal Reserve governor Christopher Waller, speaking before the release, said he was leaning towards a rate increase in December even if October's figures were softer than expected, so a higher reading only strengthens that view. Behind the numbers lie two large forces. Crude oil traded at just over $70 a barrel before the US-Israel war with Iran began and is now above $100. Tariffs are also feeding through: research by the Federal Reserve Bank of New York found that US-based businesses absorbed nearly 90% of the cost of the new tariffs, and that every percentage point added to average tariffs led to a price rise of nearly 0.25% in consumer goods after a year.
The counter-argument is that the direction of travel is improving. The 0.4% monthly rise was well below the 0.6% in September, and the pace of energy price increases dropped sharply, to 0.7% in October from 5.2% in September. That suggests the shock from higher oil prices is fading rather than compounding. The 0.1 percentage point gap between the result and expectations is also small, and the BBC noted that a slower rise in prices does not mean prices are falling, only that they are climbing more slowly. Most of the global tariffs were struck down by the Supreme Court in February, even though a new 10% global tariff replaced them, and inflation, while above the Fed's preferred level, has been much higher in earlier years, including during the Covid pandemic and after Russia's full-scale invasion of Ukraine in early 2022.
The decision at stake in December affects far more than Wall Street. Higher interest rates would raise borrowing costs for mortgages, car loans and credit cards for American households already stretched by prices, and they would push up the cost of capital for businesses. Because the dollar and US interest rates influence borrowing costs around the world, a Fed rate rise could also tighten conditions in emerging economies and complicate the plans of other central banks. Voters have just signalled that the cost of living is their primary concern, which makes the Fed's choice politically sensitive as well as economic.
October's inflation report offers evidence for both sides of the Fed's debate. Prices are still rising faster than forecast, but the underlying pace has cooled since September. The December meeting will show which signal the central bank trusts more.
