WASHINGTON, Nov 10 (Reuters) - Odds the US Federal Reserve may raise interest rates half a percentage point at its December meeting jumped on Tuesday after new data showed prices rising faster than expected and clearing the bar set by one key policymaker for considering a quicker pace of rate hikes.
The Consumer Price Index rose 0.4% month over month in October, a drop from the 0.6% in September as energy inflation receded, but the index excluding volatile food and energy prices
rose 0.3% for the third month in a row, evidence of persistent "core" inflation that also showed signs of spreading through the economy.
In comments overnight in London, Fed Governor Christopher Waller said that a core reading of 0.3% for October would prompt him to consider a half point hike at the Fed's December 8-9 meeting. With a quarter-point rate hike all but assured, market bets on a larger increase were rapidly building amid a broad bond market selloff and at midmorning were close to 15%.
If core consumer prices rise 0.3% or more from September, "a stronger policy move may be needed," Waller said at a conference hosted by King's Business School and the Money Macro & Finance Society. "In that case, I believe a 50 basis point hike in the policy rate should be considered at the December meeting."
Sticking with a smaller rate increase, Waller said, risks hurting the Fed's inflation-fighting credibility given inflation that's too high and appears to be broadening out. Economists had expected core monthly inflation to drop to 0.2% in October.
The CPI data and Waller's comments drove a powerful selloff in the US Treasury market, with the yield on 2-year notes — a proxy for Fed policy expectations — rising by the most since early April 2025.
