“美国例外论“面临考验：美债避险属性承压 美元霸权遭遇欧元挑战

Group 1 - The concept of "American exceptionalism" highlights the unique attractiveness of the U.S. financial system, which allows American enterprises and government to access low-cost capital, creating a positive cycle that attracts global funds [2][5] - The U.S. bond market totals $29 trillion, accounting for 40% of global fixed-income assets, while the U.S. stock market has a total market capitalization of $65 trillion, representing a significant portion of the global equity market [5] - Over the past decade, U.S. corporate earnings growth has significantly outpaced other regions, with S&P 500 earnings per share doubling, compared to a much lower increase in the European Stoxx 600 index [5] Group 2 - Signs of challenges to "American exceptionalism" are emerging, including high tariffs on imports and concerns over the sustainability of federal debt, which could lead to a negative spiral of rising debt and interest rates [8][11] - Despite these challenges, there is currently no clear evidence of large-scale foreign investor withdrawal, as foreign holdings of U.S. Treasuries remain near historical highs, and the S&P 500 index continues to reach new highs [11] - The average price-to-earnings ratio of S&P 500 constituents is currently 50% higher than that of the MSCI global index (excluding the U.S.), indicating a need for sustained earnings growth from U.S. companies [11] Group 3 - The "TINA" (There Is No Alternative) investment logic is being tested, with some strategists viewing this as an opportunity to rebalance portfolios, and U.S. companies are increasingly issuing euro-denominated bonds to hedge policy risks [14] - The debate surrounding "American exceptionalism" also touches on social equity, as income growth has disproportionately favored the top 1% of earners compared to the middle and lower classes [14] - Despite the challenges, some analysts argue that the U.S. retains structural advantages, including a growing labor force, high corporate profit margins, and a large, homogeneous domestic market [14]
