Finance Minister Choi Sang-mok said Thursday that the government will take “active measures” in the event of excessive volatility in the foreign exchange market, as the South Korean won weakened past the psychological threshold of 14-hundred won against the U.S. dollar.

The minister made the “verbal intervention” during a meeting with economic policymakers in Seoul. 

Noting the existence of lingering economic uncertainties in view of expected policy changes in the U.S. after Donald Trump’s reelection, Choi said a team jointly assembled by different government agencies will closely monitor the market. 

The finance minister also urged officials to swiftly implement active market stabilization measures in the event of excessive volatility in the foreign exchange market. 

Unlike direct government intervention, which involves the actual buying and selling of dollars, verbal intervention is a policy tool to reduce sharp fluctuations in exchange rates by issuing a public statement or speech. 

Before Thursday, the most recent verbal intervention occurred in mid-April, when the won-dollar rate neared 14-hundred won due to escalating tensions in the Middle East.
