The dollar index eased toward 104.3 on Tuesday, giving back some of its recent, but remains close to a 20-year high reached last week as expectations that the Federal Reserve will continue to aggressively tighten monetary settings supported the currency. The Fed raised its benchmark interest rate by 75 basis points last week, the largest increase since 1994. In the latest commentary, Fed Governor Christopher Waller said Saturday he would support another hike of a similar scale at the central bank’s July meeting should economic data come in as he expects. Meanwhile, Cleveland Fed Bank President Loretta Mester warned Sunday that the risk of a US recession is increasing, and that it will take several years to return to the central bank’s 2% inflation goal. Investors now look ahead to Fed Chair Jerome Powell’s appearance before Congress on Wednesday and Thursday for clues on the likely path forward for US monetary policy.
