Bets that currency deals will form part of trade negotiations with the US have helped lift a string of Asian currencies against the dollar, as traders look for signs that countries will offer to scale back intervention to appease President Donald Trump.

The Korean won, Japanese yen and Taiwan dollar have rallied strongly in recent weeks, making them Asia’s top-performing currencies this year, in the expectation that talks on lowering sweeping US trade tariffs will touch on how countries manage their dollar exchange rates.

“It is quite likely that the market believes that the US will look to introduce some language around exchange rates, as part of broader trade agreements with some trading partners,” said Nathan Venkat Swami, head of Asia-Pacific FX trading at Citigroup.
