South Korean foreign exchange authorities purchased $20 billion from SK hynix on September 2, 2026. This transaction absorbs the dollar inflow from the chipmaker's record $26.5 billion American Depositary Receipt (ADR) offering in the United States. The intervention aims to stabilize the South Korean won.
The July ADR sale was the largest U.S. share offering ever by a foreign company. Investors oversubscribed the offering by more than seven times. This move underscores the significant impact of capital repatriation on national currency markets.
