全球资产配置热点聚焦系列之二十九：长端日债利率上行归因与套息交易后续展望

Group 1 - The core reason for the significant rise in long-term Japanese bond yields is attributed to the recovery of the Japanese labor market and the subsequent increase in wage growth, which has driven inflation upward. The unemployment rate in Japan has been declining rapidly, and the labor participation rate has been increasing, leading to a substantial rise in wage growth since 2023 [14][19][20] - The issuance of 1 trillion yen 20-year government bonds on May 20, 2025, saw a bid-to-cover ratio drop to 2.5 times, the lowest since 2012, and a tail difference that surged to 1.14, the highest since 1987. This resulted in a significant increase in the 30-year Japanese bond yield to 2.74%, causing the 30Y-10Y yield spread to rise sharply to 126 basis points, placing it in the 99.3 percentile since 2000 [3][8][14] Group 2 - The short-term outlook suggests that the upcoming auctions of 40-year, 10-year, and 30-year Japanese government bonds from May 28 to June 5 may lead to further increases in yield spreads due to heightened liquidity risks in the long-term bond market and sustained high inflation levels [30][31] - The Bank of Japan's actions in mid-June will be crucial for the trajectory of Japanese bond yields, as they aim to balance currency appreciation, economic recovery, and normalization of the bond market [31][32] Group 3 - The current state of carry trade is influenced by the ongoing dynamics between Japanese and U.S. bond markets. Despite the significant rise in Japanese bond yields, the 10Y U.S.-Japan yield spread has remained relatively stable, indicating that carry trade opportunities still exist [34][38] - If the 10Y Japanese bond yield rises faster than the 10Y U.S. bond yield, it could lead to increased volatility in global bond and equity markets, as the interconnectedness of developed market yields may trigger a broader rise in rates [48][50]
