日本长债重回“危机模式”，“长债危机”会蔓延到股市吗？

Group 1 - A "slow-motion crisis" is brewing in the global government bond market, with Japan at the forefront, driven by concerns over fiscal expansion and weakening investor demand [1][2][6] - The yield on Japan's 20-year government bonds has surged to 2.655%, the highest level since 1999, while the 10-year yield reached 1.61%, a new high since 2008, indicating rising market anxiety [1][2] - The sharp rise in yields is primarily due to worries about Japan's fiscal situation, with expectations of increased government bond issuance following the ruling coalition's loss in the July Senate elections [2][3] Group 2 - There is a significant decline in overseas investor demand for Japanese government bonds, with net purchases of 10-year and longer bonds dropping to 480 billion yen in July, only one-third of June's amount [2][3] - The withdrawal of foreign investors is exacerbating market vulnerability, as they have been the dominant source of demand for long-term bonds [3][4] - The trend of rising yields and declining demand for long-term bonds is part of a broader global trend, with warnings from analysts about the potential instability in the bond market [2][6] Group 3 - Japanese corporations are shifting from long-term bonds to short-term financing in response to rising yields, which may save costs in the short term but increase refinancing risks in the long run [4][5] - The structure of corporate bond issuance has changed significantly, with bonds maturing in five years or less accounting for 75% of the total issuance, while ultra-long bonds have nearly disappeared [4] Group 4 - The concept of "fiscal dominance" is emerging, where rising government debt and interest costs exert political pressure on central banks, potentially leading to artificially low interest rates [8][9] - The OECD projects that sovereign borrowing in high-income countries will reach a record $17 trillion this year, complicating central banks' efforts to reduce their balance sheets [8] Group 5 - The rising bond yields are causing a significant decline in the relative attractiveness of stocks, with warnings that the era of "There Is No Alternative" (TINA) for stock investments may be coming to an end [6][8] - Historical trends indicate a positive correlation between Japanese long-term bond yields and volatility in U.S. equities [7]
