Korean Won Depreciated Against All G10 Currencies, Australian Dollar Up 19.9% Over Past Year

According to Yonhapinfomax, the Korean won depreciated against all G10 currencies over the past year through July 6, 2026, with the Australian dollar exchange rate rising 19.9%, the highest among major currencies. The dollar-won rate climbed 11.9%, followed by the Norwegian krone at 15.9%, Swiss franc at 11.0%, and the euro at 9.3%. The Japanese yen recorded the smallest appreciation at 0.8% against the won.

Data from the Bank for International Settlements (BIS) as of end-May showed South Korea's real effective exchange rate at 84.75, second only to Japan's 65.93 among 64 surveyed nations, indicating historical weakness. Analysts suggest the won's structural depreciation trend is likely to persist near current levels in the near term.
