BOK warns of prolonged market volatility amid Trump tariff scheme, vows swift response

The South Korean market could face heightened volatility for a longer-than-expected period due to the Donald Trump administration’s sweeping tariff policy, the central bank said Monday, calling for prompt implementation of market stabilization measures when necessary.

Bank of Korea (BOK) Deputy Gov. Ryoo Sang-dai made the assessment during an emergency task force meeting meant to review market conditions after Trump’s tariff measures have affected the stock and foreign exchange markets at home and abroad.

“Uncertainties surrounding the U.S.’ path regarding its tariff policies remain high and such a situation may be prolonged longer than expected. It is essential to closely monitor the financial and foreign exchange markets through a 24-hour surveillance system and promptly implement market stabilization measures when necessary,” Ryoo said.

Trump vowed to impose “reciprocal” tariffs on imports from most of the world, including 25 percent duties on South Korean goods, which are set to take effect on Wednesday (U.S. time). He also implemented a 10 percent “baseline” tariff on foreign imports starting Saturday.

Ryoo and other officials said the recent tariff scheme was “strong,” and the move is feared to spark a global trade dispute, according to the BOK.

Trump’s tariff policy battered the local stock market Monday, with the benchmark Korea Composite Stock Price Index (KOSPI) sinking more than 4 percent as of 11:30 a.m.

The South Korean currency also traded markedly lower against the U.S. dollar, nearing the 1,470 won mark, a level unseen in about 16 years since 2009.
