By Bruno Federowski SAO PAULO, Sept 27 (Reuters) - Latin American currencies weakened on Wednesday as the market digested comments from Federal Reserve Chair Janet Yellen which seemed to confirm that further U.S. interest rate hikes are coming soon.
In an address on Tuesday, Yellen said it would be "imprudent" to keep rates on hold until inflation accelerates to the U.S. central bank's 2 percent target.
Her remarks added fuel to growing bets on a December rate hike, apparently contradicting those who believed concerns over the slow pace of inflation would lead the Fed to wait longer to hike rates.
