<.p>The dollar-won exchange rate finished in the low 1,340-won range, extending the South Korean currency’s gains as a persistent surge in the Japanese yen drove broader regional currency movements. According to Infomax data cited by Yonhap Infomax, the exchange rate closed at 1,342.80 won per dollar, dropping 2.80 won from the previous session’s Seoul close of 1,345.60 won.
Trading opened at 1,344.40 won before the won rapidly strengthened to an intraday low of 1,336.90 won during morning trading hours in Seoul. Exporter settlement inflows and a sharp appreciation in the yen catalyzed the dollar’s downward slide early in the session. The dollar-yen exchange rate slid into the 152-yen range, marking its weakest level in approximately seven months since mid-February.
Support Levels and Corporate Demand
Selling pressure eased as the rate approached the 1,330-won threshold, where bargain hunters stepped in to buy dollars. Market participants noted that the National Pension Service halted currency hedging operations and initiated dollar purchases, establishing a firm floor beneath the exchange rate. Following the 1,336.90-won trough, the dollar pared its losses and stabilized in the mid-1,340-won band by the close of the Seoul session.
Activity shifted overseas, with the exchange rate hovering near Seoul closing levels during London trading before edging lower in New York. The weakening dollar index drove the downward movement amid sustained yen strength. The dollar-yen pair traded near the 153-yen range as markets weighed potential interest rate hikes from the Bank of Japan alongside heightened vigilance from foreign exchange authorities.
Official Commentary and Energy Markets
Japanese Finance Minister Satsuki Katayama addressed recent market trends during the session, stating that the government’s stance on responding to foreign exchange markets remains unchanged from the policy applied during past joint U.S.-Japan intervention efforts.

Energy markets experienced intraday volatility as West Texas Intermediate (WTI) crude oil touched $95 per barrel during London transactions before trimming gains to settle near $93 per barrel in New York. The fluctuations followed escalating armed clashes between Saudi Arabia and Yemen’s Iran-backed Houthi movement.
