BCT：穆迪降美信用评级 市场或倾向中短期美债及欧债

Core Viewpoint - Moody's downgraded the U.S. long-term issuer and senior unsecured credit rating from the highest level "AAA" to "Aa1," marking the loss of the highest rating from all three major credit rating agencies [1] Group 1: Impact on U.S. Debt Market - The downgrade is expected to increase short-term volatility in the U.S. Treasury market, particularly for long-term bonds, leading investment managers to favor holding medium to short-term U.S. Treasuries and to pay more attention to European bonds [1] - Concerns over the U.S. economic outlook and budget deficit may intensify due to Moody's action, especially as the market has not fully recognized the downward impact of new tariff policies on the U.S. economy [1] - The U.S. faces a peak of $6.5 trillion in maturing debt in June and an upcoming debt ceiling crisis in August, which historically has led to market tension despite past compromises by Congress [1] Group 2: Investment Strategies - Investment strategies should prioritize risk diversification, with recommendations to increase holdings in Asian investment-grade bonds to mitigate volatility risks and avoid over-concentration in U.S. assets [2] - The downgrade does not indicate an imminent recession for the U.S. economy but reflects a recognition of the government's failure to control fiscal deficits and debt growth effectively [3] - Despite the downgrade, recent U.S. Treasury auctions have shown stable market demand, indicating no significant sell-off or capital outflow, suggesting that investors should maintain a diversified investment portfolio without making drastic adjustments [3]
