Seoul: The Korean currency's volatility over the US dollar deepened in April due to uncertainty surrounding Washington's sweeping tariffs on American imports, according to central bank data on Sunday.

According to Qatar News Agency, the average daily fluctuation in the won-dollar rate for April was 9.7 won, or 0.9%, according to data by the Bank of Korea (BOK), cited by Yonhap News Agency.

This marked the largest volatility since November 2022, when fluctuations reached 12.3 won and 0.9% amid optimism over a potential shift in the US Federal Reserve's monetary policy.

The April figures were also far higher than those of March, which were 4.3 won and 0.29%.

Experts forecast that the won-dollar exchange rate will remain volatile, likely hovering around 1,400 won, with future movements closely tied to developments in US-China trade talks.
