$20B FX Intervention Seeks to Stabilize South Korea's Currency Market

South Korea's foreign exchange authorities have made a significant move to stabilize the country's currency market by purchasing $20 billion in repatriated US dollars from SK Hynix, the nation's largest chipmaker. The Foreign Exchange Stabilization Fund, managed by the finance ministry and the Bank of Korea, bought the funds through over-the-counter transactions as SK Hynix repatriated the dollars it raised on Wall Street after listing its American depositary receipts in July.

The move is a departure from traditional FX interventions, aimed at stabilizing market volatility while replenishing South Korea's depleted forex reserves. The country's currency has seen a significant recovery recently, with the dollar-won rate gaining over 12% in two months after hovering near a 17-year low of 1,550 in late June.

The repatriation of $20 billion by SK Hynix was part of its largest US offering by a foreign issuer, which raised $26.5 billion to finance new factories and equipment for meeting surging AI chip demand. The Foreign Exchange Stabilization Fund's asset breakdown and current size are not officially disclosed, but market participants have speculated that the proportion of greenbacks within the fund has severely declined in recent months.
