KRW/USD breaks 1,500 again as Japan's 10-year JGB hits 29-year high

The Korean won broke back through the 1,500 per dollar threshold on May 15, 2026, trading at 1,500.2 at 2:13 PM KST — its first time at that level since April 7. The currency opened the session at 1,494.2 and had weakened for six consecutive trading days from a May 7 low of 1,454.0, a cumulative depreciation of roughly 46 won over that stretch. The prior day's close was 1,491.0, putting the daily gain at 9.2 won.

The proximate catalyst was Japan's bond market. Japan's 10-year government bond (JGB) yield rose as high as 2.72%, its highest level in 29 years, driven by inflation concerns from rising international crude oil prices. The spike raised the risk-free benchmark for yen-denominated assets, spurring a broad risk-off rotation across Asian markets and weakening regional currencies including the Korean won.

US monetary policy expectations added further pressure. Growing market conviction that the Federal Reserve's rate-cut cycle has effectively ended — driven partly by the same inflationary commodity pressures behind the JGB move — kept the dollar index supported. Simultaneously, foreign investors net sold over KRW 5 trillion in a single session on the Korean equity market, converting proceeds into dollars and directly amplifying upward pressure on USD/KRW. The move coincided with KOSPI's historic 8,000 breach and subsequent circuit-breaker trigger, broadening the risk-off backdrop.

The 1,500 level carries dual implications. Export-heavy sectors such as semiconductors and autos benefit from higher domestic-currency revenues, but companies with large USD-denominated liabilities and import-dependent manufacturers face increased cost pressures. Key variables: the Bank of Japan's (BOJ) next policy decision, international oil prices, and the Federal Reserve's forthcoming forward guidance on the rate path.
