Emerging Asian currencies strengthened against a weaker dollar on Thursday after Federal Reserve Chair Jerome Powell all but confirmed a month-end rate cut to prop-up a cooling economy. Global risk assets, including the region's currencies, welcomed the prospect of monetary support from the Fed, after spending most of this week on the edge after solid US jobs data last week doused hopes for a large rate cut at its July 30-31 meeting.
Powell, in his congressional testimony on Wednesday, confirmed that the US economy is still under threat from disappointing factory activity, tame inflation and a simmering trade war. June inflation readings from the world's biggest economy are also scheduled later in the day.
