The dollar and the euro traded cautiously on Wednesday as investors refrained from taking risky bets a day ahead of a key speech by Federal Reserve Chairman Jerome Powell.
Amid growing speculation Powell could unveil a softer policy stance towards inflation at the annual Jackson Hole retreat on Thursday, investors are bracing for the Fed's possible new steps to prop up the U.S. economy.
