Core Viewpoint - Moody's downgrade of the US credit rating has triggered significant turmoil in the US capital markets, leading to a "sell America" trading strategy and a simultaneous decline in stocks, bonds, and currencies [1][12]. Bond Market - The US Treasury market has experienced a large-scale sell-off, with the 30-year Treasury yield rising over 12 basis points to surpass the psychological 5% mark, reaching 5.02%, the highest level since November 2023. The 10-year Treasury yield also climbed above 4.5%, indicating investor concerns about the long-term fiscal health of the US [2][4]. - Analysts from Wells Fargo predict that the yields on 10-year and 30-year US Treasuries will increase by an additional 5-10 basis points due to the impact of Moody's downgrade [3].

Major tech stocks like Nvidia, Apple, and Tesla have also seen declines of over 2% and 3% respectively [4][7][8]. Currency Market - The uncertainty surrounding US debt issues has led to a decline in the US dollar index by over 0.7%, while traditional safe-haven currencies such as the Japanese yen and Swiss franc have gained. The euro has appreciated by approximately 1% against the dollar, reaching its highest level since May 9 [3][4]. Commodity Market - Gold, as a safe-haven asset, has rebounded after a previous correction, with spot gold prices rising above $2,440 per ounce. Analysts suggest that gold is benefiting from the deteriorating US fiscal situation, a trend that may continue for an extended period [9]. Investment Strategy - Following Moody's downgrade, market analysts believe that investors will reassess the risk premium associated with US assets, particularly in light of the upcoming expiration of Trump's tax cuts and the uncertain direction of fiscal policy under the new government. This has led to a renewed "sell America" strategy among Wall Street traders [12].
