Amid the current U.S.-China technological race, the U.S. has imposed export controls to deny China access to strategic technologies. We document that these measures induced sizable losses on U.S. suppliers and prompted a broad-based decoupling of U.S. and Chinese supply chains. Once their Chinese customers are added to the export control list, U.S. suppliers experience negative abnormal stock returns, wiping out $130 billion in market capitalization, as well as a drop in profitability and employment. These suppliers are also more likely to terminate relations with Chinese customers, including those not targeted by export controls. We find no evidence of reshoring.
