债市策略思考：年内债市三轮调整差异对比

Core Insights - The third round of bond market adjustments in 2025 may not be over yet, but there is potential for a delayed cross-year market rally if monetary easing expectations increase in January-February 2026 [1][3][27] Group 1: Understanding Recent Adjustments - The current bond market adjustment shows a structural characteristic where ultra-long-term bonds lead the decline, with the 30-year treasury bond reaching a peak yield of 2.28% on December 16, while the 10-year bond primarily experienced a corrective trend [1][11] - The adjustment in ultra-long-term bonds reflects weakened both allocation and trading power, with a significant increase in the supply of bonds over 10 years, reaching 1.86 trillion yuan by December 19, 2025, accounting for 11.66% of total bond issuance [13][19] - The adjustment pattern indicates that the third round may still be ongoing, potentially mirroring the structure of the second round, with the 10-year bond yield fluctuating in an adjustment-recovery-adjustment manner [24][25] Group 2: Comparison of Adjustment Rounds - In 2025, there have been three notable rounds of adjustments, with the first round driven by unexpected tightening of the funding environment, leading to a significant rise in short-term rates [2][19] - The second round was characterized by a simultaneous rise in stock prices and a decline in bond prices, indicating a shift in investor sentiment and a reduction in bullish sentiment towards bonds [22] - The third round, starting from November 3, 2025, has shown a different driving force, primarily influenced by institutional behavior and the resumption of bond trading, rather than the funding and stock-bond dynamics that characterized the previous rounds [2][22] Group 3: Cross-Year Market Trends - Historically, the bond market has exhibited a calendar effect around the New Year, often showing upward trends before the Spring Festival, with notable increases in bond yields observed in 2022, 2024, and 2025 [3][26] - The 2025 cross-year market saw a decline of approximately 50 basis points in the 10-year bond yield from T-60 to T-18 days before the Spring Festival, followed by a period of consolidation [3][26] - If the third round of adjustments continues, the potential for a delayed cross-year rally remains, contingent on favorable monetary policy developments [27]
