Most emerging Asian currencies strengthened on Thursday as the dollar weakened following seemingly dovish minutes from the Federal Reserve's last policy meeting and possible new US tariffs. While the minutes showed most policymakers thought it likely another interest rate increase would be warranted, the minutes also assuaged fears the Fed would speed up the tempo at which it raises rates.
"The FOMC minutes left little clue with regards to prospects for a fourth hike for 2018, although expectations for the next hike were cemented further," OCBC Bank said in a note. Caution was magnified by new setbacks in US-China trade talks and as US President Donald Trump raised the prospect of new tariffs on imported cars.

Bank of Korea Governor Lee Ju-yeol said the vote to hold rates was unanimous, upsetting predictions that dissenting votes may have signalled a rate hike later in the year.
