Bank of Korea2026-09-10 03:47:28Bank of Korea warns overseas derivatives tied to chipmakers may amplify volatilityThe Bank of Korea has called for tighter monitoring of overseas derivatives linked to South Korean chipmakers, saying their rapid growth could magnify swings in the domestic market. In its semiannual monetary policy report submitted to the National Assembly on Thursday, the central bank said the KOSPI’s unprecedented volatility from January to July was driven by a heavy concentration in semiconductor stocks, portfolio rebalancing by foreign investors, and the buildup and unwinding of domestic leverage. It also pointed to leveraged bets by Situational Awareness as a recent example. According to the report, global banks and ETF managers hedging total return swaps traded Korean cash equities, futures, and options, which appeared to amplify local stock-price moves. While the Bank of Korea did not cite a specific case, it said an unusual trade in SK hynix in July triggered nearly $60 million in liquidations in the offshore digital-asset market, highlighting rising cross-market risks tied to leveraged products linked to South Korean chipmakers.860
