The dollar index rose slightly to 100.5 on Tuesday, staying near its highest level since late July as a more hawkish Federal Reserve stance supported expectations for additional interest rate hikes this year. Chicago Fed President Goolsbee said the central bank cannot ignore repeated and persistent supply shocks, while St. Louis Fed President Musalem said further increases may be needed to return inflation toward the Fed’s target. The Federal Reserve raised rates for the first time in three years last week and signaled further tightening later this year. Oil prices continued to decline but recovered from session lows as traders assessed diplomatic efforts to end the conflict in the Middle East, while markets also watched for possible currency intervention to support the yen.
