On June 12, sources revealed that global banks are restricting hedge funds' leveraged bets on top Asian chipmakers, including SK Hynix and Samsung Electronics, due to concerns over a potential stock price correction. Brokers such as Citigroup, JPMorgan Chase, and Goldman Sachs have raised financing costs for hedge funds using swaps to bet on these companies' stocks, while tightening limits on the size of new trades and counterparties. Some banks have even rejected new swap trade requests or are evaluating them on a case-by-case basis. Similar measures have also been implemented for Taiwan Semiconductor Manufacturing Company (TSMC).
