日美国债拍卖双双遇冷，“风暴”过后谁来接盘？

Group 1 - Japan's 20-year government bond auction on May 20 was disappointing, with a bid-to-cover ratio of only 2.5, the lowest since 2012, and a tail difference of 1.14, the highest since 1987 [1][3] - The demand for U.S. 20-year bonds was also weak following Moody's downgrade of the U.S. credit rating, leading to rising long-term interest rates, with the 10-year yield approaching 4.6% and the 30-year yield exceeding 5% [1][7] - The Japanese bond market is experiencing a trend where foreign investors are buying while domestic investors are selling, with life insurance companies facing significant losses and refusing to purchase long-term bonds [1][4] Group 2 - The poor performance of the Japanese bond auction is attributed to two main factors: regulatory changes prompting insurance companies to buy long-term bonds and an oversupply of long-term bonds due to excessive issuance by the government [3][4] - The Bank of Japan's long-term bond holdings have decreased by 2.2% to 576.6 trillion yen since last July, and it plans to reduce bond purchases further, which may impact market stability [4][10] - Japan's debt-to-GDP ratio exceeds 250%, significantly higher than the U.S. at 120%, yet the Japanese bond market has not faced a crisis due to the Bank of Japan's support [4][5] Group 3 - The U.S. Treasury auctioned $16 billion of 20-year bonds with a final yield of 5.047%, indicating weak demand and a need for higher yields to attract buyers [7][8] - The market is concerned about the impact of rising yields on the stock market, with historical data suggesting that significant increases in yields can lead to stock market pressure [8][9] - Analysts suggest that the U.S. government may need to adjust its bond issuance strategy to alleviate market pressure, and the Federal Reserve could consider yield curve control (YCC) as a potential measure [9][10]
