Federal Reserve Chair Kevin Warsh spoke at the International Monetary Fund meetings in Bangkok on Friday, offering no indications on rate decisions at the Fed's Oct. 27-28 meeting. 

The Fed chair didn't endorse or reject his colleagues' indications that the Fed isn't rushing to raise rates at the upcoming meeting, the Wall Street Journal reported. 

In September, the Fed raised rates by a quarter percentage point to between 3.75% and 4%, which was the first increase in three years. The decision followed rising energy prices and higher costs stemming from the AI-investment boom. 

Speculation about additional hikes followed reports this week of unexpected increases in inflation. The cost of goods and services increased 0.6% from August to September and 3.7% compared to the same time last year, the Bureau of Labor Statistics reported Wednesday. 

September's producer price index rose 6.3% on an annual basis, the largest 12-month increase since climbing 6.1% in December 2022, according to the Bureau of Labor Statistics.
