South Korea's financial authorities, including the central bank governor Rhee, have expressed concerns over recent excessive volatility in the foreign exchange market. In a CNBC interview, Governor Rhee noted the market's excessive moves and stated readiness to deploy stabilization measures if volatility continues. The South Korean FX Authority highlighted undesirable herd-like behavior and is closely monitoring the market with caution on currency movement, supply, and demand. This response comes as the South Korean won has rapidly weakened, touching critical levels, prompting increased scrutiny from policymakers in Seoul.
