Japanese and South Korean authorities likely conducted a coordinated intervention in the foreign exchange market on Thursday to stem the fall of the yen and the won against the U.S. dollar. The yen surged to the upper 157 range, its strongest level since mid May, while the South Korean won hit a nine month high of 1,418 won per dollar. Some reports indicate Japan may have spent between 6 trillion and 7 trillion yen on the operation. While Japanese Finance Minister Satsuki Katayama and South Korean Deputy Finance Minister Moon Ji-sung declined to officially confirm the intervention, Moon stated that Seoul and Tokyo are maintaining close coordination.

The move occurred as the yen had been trading near its weakest level in nearly 40 years. U.S. Treasury Secretary Scott Bessent supported the sentiment that the yen is undervalued and that excessive volatility is not healthy. Reports also suggest the New York Federal Reserve performed a dollar yen rate check on behalf of the U.S. Treasury, which is often a precursor to direct intervention.

Simultaneously, the Bank of Japan decided to keep its policy interest rate at around 1 percent. However, Governor Kazuo Ueda signaled that the bank would monitor the impact of yen developments on prices and the economy, with some analysts interpreting this as a hint of a faster interest rate increase to avoid falling behind the curve. In the equity markets, the surge in currencies coincided with a rally in Asian stocks. South Korea's KOSPI saw a significant jump, while Japan's Nikkei also advanced.
