South Korea starts 24-hour trading of the US dollar–South Korean won (USD/KRW) in an effort to increase market accessibility and improve liquidity outside normal trading hours. Multiple reports say the expanded trading schedule allows banks and other market participants to transact in the USD/KRW pair around the clock, rather than being limited to daytime sessions. The change is designed to better reflect global currency trading, where activity often continues across time zones. Sources also indicate the move builds on ongoing efforts to modernise South Korea’s foreign exchange market infrastructure and align it with international practices. The start of around-the-clock trading follows preparation work by market authorities and relevant financial institutions to support continuous quotations and orderly trading. Overall, the shift increases the availability of USD/KRW transactions for participants needing to hedge currency exposure or respond to news developments that occur after local market hours.
