债基2025年Q4季报分析：从2025Q4季报看利率债基变化

Group 1: Report Investment Rating - No information on the industry investment rating is provided in the report. Group 2: Core Viewpoints - The bond market in 2026 may perform better than expected. The Central Economic Work Conference in December 2025 proposed to "flexibly and efficiently use various policy tools such as reserve requirement ratio cuts and interest rate cuts", and China is still in a large cycle of reserve requirement ratio cuts and interest rate cuts. It is expected that the yield of the 10 - year Treasury bond in 2026 will fluctuate in the range of 1.6% - 1.9%. The big opportunity for ultra - long bonds may need to wait until the institutional stock market expectations significantly decline and the policy interest rate is cut, or until Q2 2026 or later. It is recommended to focus on the band - trading opportunities of ultra - long bonds, allocate 3 - 5Y capital bonds to obtain coupons, and pay attention to multi - asset investment opportunities [2].

The average duration of heavy - positioned Treasury bonds in active interest rate bond funds in Q4 2025 fell to 7.9 years. From Q3 2025 to Q4 2025, the duration of interest rate bond funds measured based on heavy - positioned bonds decreased from 3.38 years to 3.23 years, among which the average duration of heavy - positioned interest rate bonds decreased by 0.14 years (the duration of Treasury bonds decreased by 0.70 years to 7.9 years). From the remaining term of heavy - positioned bonds, active interest rate bond funds increased the allocation of bonds with a term of 1 - 5 years (the proportion in Q4 2025 was 58.7%, an increase of 4.8 pct compared with the previous period). From the remaining term of heavy - positioned Treasury bonds, the proportions of Treasury bonds with a term of 1 year or less, (1, 5) years, and 20 years or more in Q4 2025 were 9.9%, 27.8%, and 23.6% respectively, with changes of - 4.0 pct, + 6.1 pct, and - 4.8 pct compared with Q3 2025 [2].

The average annual yield of interest rate bond funds in 2025 was 0.50%, a significant decrease compared with 4.42% in 2024 [2]. Investment Strategy Changes in Q4 2025 - Since the second half of 2025, the bond market trend has often deviated from the fundamentals and has been mainly dominated by institutional behavior. Securities firms' proprietary trading, bond funds, and annuities have systematically reduced the duration of bond holdings, resulting in a significant increase in the yield of ultra - long bonds. The scale of active pure - bond funds decreased significantly in H2 2025. After the new regulations on public fund sales fees were implemented, the scale of active bond funds may stabilize, and bond ETFs are expected to develop rapidly [2].
