U.S. Treasury Secretary Scott Bessent has pointed to significant volatility regarding the Japanese yen and the South Korean won.

This instability affects regional trade and investment patterns, as both currencies have shown simultaneous weakness. The trend complicates the economic landscape for Asian markets that rely on stable exchange rates to maintain export competitiveness.

During a segment on YTN News, Professor Seo Eun-sook of Sangmyung University's Department of Economics and Finance said that Secretary Bessent specifically highlighted the volatility of the won. She said that both the yen and the won are currently in a state of weakness.

Currency fluctuations are often tied to the "yen carry trade," a practice where investors borrow yen at low interest rates to invest in higher-yielding assets elsewhere. When the yen strengthens or volatility spikes, these trades can unwind rapidly, creating shocks across global markets.

The impact is visible in current trading figures. Anchor Cho Tae-hyun said the won-dollar exchange rate has reached the 1,420 won level [1].

This level of volatility suggests a period of instability for the South Korean currency. The simultaneous decline of the yen and won reflects broader economic pressures in the region, pressures that the U.S. Treasury is now monitoring closely.

"The yen is weak and the won is also weak," said Professor Seo Eun-sook.

The simultaneous weakness of the yen and won indicates a systemic volatility in Asian currency markets. When the U.S. Treasury explicitly notes this instability, it often precedes closer monitoring of currency interventions or policy shifts to prevent regional economic contagion, particularly regarding the unwinding of carry trades.
