美债市场“起义”：20年期拍卖翻车恐成“债券卫士”归来序曲

Core Viewpoint - Concerns over the expanding deficit threatening the U.S. safe-haven status are reflected in the weak demand for a $16 billion 20-year Treasury auction, leading to declines in U.S. stocks, bonds, and the dollar [3][4]. Group 1: Treasury Auction Results - The U.S. Treasury auctioned $16 billion of 20-year bonds with a winning yield of 5.047%, marking the second instance of yields surpassing 5% since the bond's introduction five years ago [3]. - The winning yield was 24 basis points higher than April's 4.810% and approximately 1.2 basis points above the pre-issue rate of 5.035%, indicating a significant tail risk [3]. - This auction is considered one of the worst performances for this maturity since its launch, reflecting deteriorating investor sentiment towards U.S. Treasuries [3]. Group 2: Market Reactions - The weak auction results exacerbated a multi-week sell-off in Treasuries, highlighting growing investor dissatisfaction with increasing U.S. debt levels [3][4]. - The S&P 500 index fell by 1.5%, while the 10-year Treasury yield reached 4.607%, the highest since February 13 [3]. - Analysts noted that the market's reaction to the auction signals a collective avoidance of U.S. debt by foreign buyers, with rising financing costs putting pressure on the stock market [4]. Group 3: Political and Economic Implications - The White House intensified pressure on Republicans to approve Trump's tax plan, which could add trillions to the already ballooning budget deficit [6]. - Concerns were raised that the current administration is unlikely to make meaningful cuts to the deficit, as highlighted by former Treasury Secretary Steven Mnuchin [6]. - The bond market is seen as a barometer for fiscal sustainability, with rising yields indicating that investors are increasingly wary of the government's fiscal policies [7]. Group 4: Debt and Deficit Statistics - The U.S. public debt-to-GDP ratio is approximately 100%, with interest payments projected to reach about $880 billion in 2024, exceeding defense spending [8]. - The amount of outstanding debt surged from under $14 trillion at the end of 2016 to nearly $30 trillion [8]. - The annual sales of U.S. government debt reached a record $2.6 trillion last year, indicating a significant increase in borrowing [8].
