Core Viewpoint - The global tariff storm initiated by the U.S. government may reset the global trade and international monetary systems, potentially undermining the dollar's status as the world's reserve currency [1][15]. Capital Flow Analysis - In the first half of the year, the U.S. attracted a net inflow of international capital amounting to $767.7 billion, a 2.78-fold increase year-on-year, despite a 10.8% decline in the dollar index, marking the largest drop since 1973 [2]. - The marginal changes in capital flow reveal that the dollar's decline is not directly linked to foreign investors selling U.S. securities but rather to a reduction in interest from private foreign investors [2][3]. - Foreign investors did not significantly reduce their holdings of U.S. securities but opted to decrease their cash holdings in dollars while increasing investments in foreign securities [3][4]. U.S. Securities Investment Trends - Foreign investors predominantly increased their holdings in U.S. long-term securities, particularly U.S. Treasury bonds, while significantly reducing purchases of U.S. corporate stocks, indicating a lowered risk appetite due to U.S. policy uncertainties [4][5]. - The net purchase of U.S. Treasury bonds reached $4,278 billion in the first half of the year, marking a historical high for semi-annual net purchases [5]. Official Foreign Investment Dynamics - Official foreign investors shifted from net selling to net buying of U.S. Treasury bonds, contributing positively to the overall net inflow of foreign capital [2][10]. - The interest from private and official foreign investors in U.S. Treasury bonds showed significant divergence, with private investors reducing their net purchases while official investors increased theirs [5][11]. Impact of New Trade Agreements - The new trade agreements aimed at reducing the U.S. trade deficit may adversely affect the dollar's status as a reserve currency, as a decrease in trade deficit could lead to a reduction in foreign capital inflows [12][15]. - The U.S. government's aggressive trade policies may lead to a decrease in foreign investment in U.S. securities, as countries commit to increasing direct investments in the U.S. to promote domestic manufacturing [15].
