Chinese regulators have reportedly instructed major commercial banks to limit new purchases of U.S. Treasuries and gradually reduce holdings for banks with high exposure. This move aims to mitigate concentration and market volatility risks. The guidance does not apply to China's sovereign foreign exchange reserves and lacks specific directives on adjustment scale or timeline. Regulators clarified that the measure is intended to diversify market risk and is not related to geopolitical factors or concerns about U.S. creditworthiness.
