May 2 (Reuters) - Emerging-market currencies weakened against the dollar on Thursday after U.S. Federal Reserve Chairman Jerome Powell said he saw no reason for a change in interest rates.

“Last night was a bit of a hawkish twist — the idea that Powell saw downward inflationary pressure as a transitory effect definitely caught markets by surprise,” said Simon Harvey, an analyst at Monex Europe.
