Asian shares are mixed ahead a decision by the U.S. Federal Reserve on interest rates. Benchmarks declined in Hong Kong, Shanghai and Seoul but rose in Tokyo and Sydney. U.S. futures edged higher while oil prices slipped. On Tuesday, the S&P 500 gained 0.5% to its highest level since early 2022, slightly below its record high, after a report showed inflation in the United States is behaving pretty much as expected. The Dow rose 0.5% and the Nasdaq composite added 0.7%. Traders still expect the Federal Reserve to stand pat on interest rates when it announces its next move Wednesday afternoon. The inflation report did cast some doubt on when rates may come down.
