申万宏源固收研究 【申万固收|机构行为】中长期利率型债基久期抬升，但分歧扩大——机构行为观察周报20251231 原创 阅读全文 ...

证券研究报告|宏观研究报告 [Table_Date] 2025 年 12 月 21 日 在中央经济工作会议"保持必要的财政赤字、债务总规模和支出总量" 的要求下，市场预期 2026 年政府债净供给规模将在 2025年高基数的背景 下，延续同比提升的趋势，尤其是超长政府债的净供给规模，可能将由今 年的 6.4 万亿元，进一步提升至 6.5-7.2 万亿元。银行、保险等配置盘，或 分别受制于利率风险指标、增量保险收入的等约束，理论上无法顺利承接 庞大的超长端供给。因此，市场在 11-15 日自发对此逻辑进行防御性定 价，超长端利率明显上行。然而实操之中，银行的利率风险考核指标并非 是一成不变的刚性变量，监管可以视当下的特殊情况，合理放松考核尺 度，提升银行消化超长政府债供给的能力。另外，央行也可通过一些特殊 方式，帮助银行完成久期指标的短期出表。 ►主线二：对结构性降息的猜想 由于今年以来居民需求、地产量价数据表现普遍不算乐观，因此，年 末市场开始对降息，尤其是LPR结构性降息存在期待。不过，当前贷款利 率降息需要考量的不仅仅是需求变化的问题，还需兼顾银行低息差压力背 后的金融系统风险。截至 2025 年三季度末 ...

Report Summary 1. Report Industry Investment Rating The report is bullish on the bond market, suggesting that the current bond market has prominent allocation value and recommends investing in 10Y China Development Bank bonds, 30Y Treasury bonds, and 5Y capital bonds. [2] 2. Core View of the Report Based on the Q3 2025 quarterly reports of bond funds, the report analyzes the changes in interest rate bond funds, including scale, asset allocation, and investment strategies. It points out that due to factors such as the significant rise in the stock market and regulatory rule impacts in Q3, the bond market deviated from the capital and economic fundamentals, leading to a decline in the quarterly returns of interest rate bond funds. Currently, the bond market has high allocation value, and the bond yields are expected to decline in a volatile manner. [2] 3. Summary by Related Content Changes in Interest Rate Bond Funds in Q3 2025 - **Scale and Asset Allocation**: As of Q3 2025, the total asset value of interest rate bond funds was 3.1 trillion yuan, a decrease of 0.44 trillion yuan from Q2 2025. The bond allocation ratio decreased, while the cash ratio increased slightly. [2] - **Heavy - Positioned Bonds**: Actively managed interest rate bond funds slightly increased their allocation to Treasury bonds and reduced their allocation to policy - financial bonds. Overall, they reduced their allocation to long - duration bonds, but actively managed funds significantly increased their allocation to Treasury bonds with a maturity of 1 year or less and continued to increase their allocation to 30 - year Treasury bonds. [2] - **Yield**: The average annualized yield of interest rate bond funds decreased from 3.96% in Q2 2025 to - 1.84% in Q3 2025. Credit bond funds had relatively stronger defensive capabilities. [2] Investment Strategy Changes in Q3 2025 In Q3, the bond market deviated from the capital and economic fundamentals. Due to the significant extension of the duration in Q2, the bond market adjustment in Q3 led to a sharp decline in the quarterly returns of interest rate bond funds. As a result, the duration was shortened, and the scale returned to the level of Q3 2024. [2] Investment Recommendations - **Market Outlook**: The bond market has prominent allocation value, and the bond yields are expected to decline in a volatile manner. The policy interest rate in Q4 may be cut by 10 - 20BP. [2] - **Investment Choices**: The top choices for bond market investment are 10Y China Development Bank bonds, 30Y Treasury bonds, and 5Y capital bonds. It is predicted that the yield of 10Y Treasury bonds will return to around 1.65%, the yield of 30Y Treasury bonds will reach 1.9%, and the yield of 5Y large - bank secondary capital bonds will reach 1.9%.

Report Industry Investment Rating No information provided in the report. Core Viewpoints - The report selects medium - duration investment - grade bond funds with large scales as samples to analyze the duration views and allocation preferences of US bond funds. In the cash bond level, as of Q2 2025, the proportions of Treasury bonds, credit bonds, and MBS in US bond fund holdings are 28.5%, 26.4%, and 36.9% respectively. Since H2 2024, funds have been more cautious about duration allocation, and their under - allocation of duration and inflation concerns may jointly push up the term premium. [3] Summary by Relevant Catalogs 0 US Bond Fund Classification - There are various types of US bond funds, including investment - grade bond funds, high - yield bond funds, government bond funds, etc. Investment - grade bond funds have the largest asset size, reaching $248.52 billion, accounting for 46.6% of the total. [4] - The report selects 20 actively - managed bond funds with large scales and using the Bloomberg US Aggregate Index as the performance benchmark as samples, which helps to better understand the duration views and allocation preferences of bond funds. [6] PART1 Cash Bonds: Analyzing Bond Funds' Variety Preferences - **Overall Position Structure**: From the end of 2021 to 2023, bond funds increased their MBS holdings, compressed their credit bond holdings, and slightly reduced their Treasury bond, municipal bond, and cash holdings. As of Q2 this year, the proportions of Treasury bonds, credit bonds, and MBS in US bond fund holdings are 28.5%, 26.4%, and 36.9% respectively. [12] - **Advantages of MBS**: MBS has higher returns than Treasury bonds, lower volatility than credit bonds, low cycle sensitivity, and relatively good valuation. Since 2023, MBS has had better valuation than credit bonds. [13][16] - **Impact on Duration**: MBS has a shorter duration than Treasury bonds and credit bonds. The increase in MBS and ABS holdings has shortened the overall duration of bond fund cash bonds. [17] - **Credit Bond Allocation**: Bond funds mainly reduced their holdings of the industrial sector in credit bonds, while maintaining stable allocations in the financial and utility sectors. From 2022 - 2023, they significantly reduced their holdings of the cyclically - sensitive industrial sector. [22] - **Comparison with Benchmark**: Compared with the benchmark (Bloomberg US Aggregate Index), bond funds are overweight in MBS and finance, and underweight in Treasury bonds and the industrial sector. [23] PART2 Derivatives: Why Do Funds Hold Long Positions in Futures? - **Increase in Treasury Futures Holdings**: Since 2022, asset management companies have significantly increased their long positions in Treasury futures, mainly holding 2Y and 5Y Treasury futures contracts. [26][27] - **Categories of Treasury Futures**: There are multiple categories of US Treasury futures, with different contract amounts and delivery conditions. As of the end of August this year, the open - interest amounts of 2Y, 5Y, 10Y, etc. Treasury futures are different. [33] - **Proportion of Mutual Funds**: As of Q4 2023, mutual funds held about $500 billion in Treasury futures, accounting for nearly half of the Treasury futures holdings of asset management institutions. Since 2022, mutual funds have concentrated on increasing their long positions in 2Y and 5Y Treasury futures. [35] - **Reasons for Holding Long Positions**: Funds hold long positions in Treasury futures to supplement the duration gap at a lower cost, allowing them to reduce the holdings of illiquid long - duration old Treasury bonds and allocate more to higher - yielding MBS/ABS. They also use Treasury futures to add leverage, and are less involved in the repurchase market. [38][43] - **Impact on the Market**: The long - position demand for Treasury futures from funds and the Fed's QT have led to a decrease in the buying of Treasury cash bonds, resulting in negative net basis and attracting hedge funds to engage in basis trading. [50] PART3 Model: Measuring the Empirical Duration of Funds - **Measurement Method**: The report uses the daily returns of 20 selected funds and five independent variables (changes in 10Y US Treasury yield, MBS spread, investment - grade credit spread, 30 - 5Y term spread, and volatility) for rolling regression. The regression coefficient of the 10Y US Treasury yield change is regarded as the empirical duration of the fund, which measures the fund's interest - rate risk exposure. [53][54] - **Relationship with Interest Rates**: Before H1 2024, funds generally adopted a configuration - based approach. Since H2 2024, they have been more cautious about duration allocation, under - allocating duration, and following the trend. Their under - allocation of duration may push up the term premium. [59][61] - **Allocation Preferences in Different Periods**: From 2022 - 2025, funds' allocation preferences changed with inflation, policy interest rates, economic fundamentals, and external shocks. For example, from 2022 - Feb 2023, they were overweight in credit and duration; from Mar - Jul 2023, they steepened the curve, under - allocated credit, and increased MBS allocations. [66][67] - **Asset Allocation Rules**: In the long - term, fund duration is generally positively correlated with interest rates. When the benchmark interest rate is low and credit spreads are relatively high, funds tend to increase credit exposure. When MBS is more attractively valued than credit bonds, funds tend to increase MBS allocations. [69][73][76]

Summary by Directory 3.1 Overall Sentiment - The bond market vitality index dropped significantly. As of September 26, it decreased by 17 pcts to 0% compared with September 19, and the 5D - MA decreased by 5 pcts to 16%. There were no warming indicators, and the cooling indicators included the implied tax rate of the 10 - year CDB bond, the trading volume of the active 10Y CDB bond / the balance of 9 - 10Y CDB bonds, the excess level of the inter - bank bond market leverage ratio compared with the average of the past 4 years, the median duration of medium - and long - term pure bond funds, and the turnover rate of the 30Y treasury bond [1][10][12]. 3.2 Institutional Behavior 3.2.1 Buying and Selling Strength and Bond Selection - The net buying strength ranking in the current bond market this week is: money market funds > large - scale banks > insurance > wealth management > other product types > others; the net selling strength ranking is: city commercial banks > rural financial institutions > securities firms > funds > joint - stock banks > foreign - funded banks. For ultra - long bonds, the net buying strength ranking is: insurance > securities firms > wealth management > other product types > others, and the net selling strength ranking is: large - scale banks > funds > city commercial banks > joint - stock banks > rural commercial banks > foreign - funded banks [19]. - The main bond types of various institutions are: large - scale banks focus on 1 - 3Y and 7 - 10Y interest - rate bonds; rural commercial banks focus on 3 - 5Y credit bonds; insurance focuses on interest - rate bonds and other bonds over 10Y; funds focus on interest - rate bonds within 1Y; wealth management focuses on interest - rate bonds within 1Y and 3 - 5Y credit bonds; other product types focus on 7 - 10Y interest - rate bonds [2][22]. 3.2.2 Trading Disk - The median duration of all - sample medium - and long - term pure bond funds decreased by 0.01 years compared with September 19. Among them, the median durations of pure interest - rate bond funds, interest - rate bond funds, and credit bond funds changed by - 0.02 years, - 0.07 years, and + 0.03 years to 5.15 years, 4.81 years, and 3.74 years respectively. The median durations of high - performing interest - rate bond funds and credit bond funds changed by - 0.07 years and + 0.10 years to 6.39 years and 4.35 years respectively [3][39]. 3.2.3 Allocation Disk - **Primary Market**: The primary subscription demand for treasury bonds and policy - financial bonds decreased this week, and the subscription demand for ultra - long bonds was differentiated. The weighted average full - market multiples of treasury bonds and policy - financial bonds decreased from 3.39 times and 3.00 times in the previous week to 2.85 times and 2.80 times respectively. For treasury bonds and policy - financial bonds over 10Y, the weighted average full - market multiples decreased from 3.63 times to 3.33 times and increased from 3.34 times to 3.40 times respectively [53]. - **Secondary Market** - **Large - scale Banks**: The increasing supply of ultra - long bonds may restrict their secondary - market承接 capacity. Since June, large - scale banks have increased their net buying of treasury bonds within 1Y, but the cumulative net buying scale this year is still far lower than that of the same period in 2024. The net buying of 1 - 3Y treasury bonds increased from May to July and declined since August. As of September 26, the cumulative net buying scale of 1 - 3Y treasury bonds this year was 7271 billion yuan [58][60]. - **Rural Commercial Banks**: Their cumulative net buying scale of current bonds this year is significantly weaker than in previous years, mainly due to the weak net buying of short - term bonds within 1Y. However, the net buying of 7 - 10Y and over 10Y current bonds is significantly higher than in previous years [74]. - **Insurance**: The net buying strength of current bonds by insurance this year is significantly higher than in previous years, mainly due to the strong buying of ultra - long bonds over 10Y. As of September 19, the ratio of insurance's cumulative net buying of current bonds to the cumulative issuance scale of government bonds over 10Y was 30.04%, higher than 29.18% at the end of September last year [80]. - **Wealth Management**: Since June, the cumulative net buying scale of current bonds by wealth management has continued to rise.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Since Q3 this year, the bond market has adjusted significantly, but the decline in the duration of public - offering bond funds is not obvious. It is expected that public - offering bond funds will maintain a moderately high duration level, with the 10 - year Treasury yield oscillating in the range of 1.7% - 1.8%. As the correlation between stocks and bonds weakens and fundamental pressure rises, the bond market environment in the fourth quarter is expected to be better than that in the third quarter [2][8] 3. Summary According to the Directory 3.1 Third - quarter Bond Market Adjustment with No Obvious Decline in Bond Fund Duration - In the third - quarter bond market adjustment, the decline in the duration of bond funds was not obvious. For example, in Q1, the 10 - year Treasury yield rose from about 1.6% in early February to nearly 1.9% in mid - March, and the median duration of the whole - market bond funds dropped from a high of 3 years to about 2.1 years. However, as of September 17, the median duration of public - offering bond funds remained at about 2.5 years, and the median duration of medium - and long - term interest - rate bond funds remained at about 3.1 years [5][14] 3.2 Four Reasons Why Bond Fund Duration is Difficult to Decrease - **Mild Adjustment and Multiple Repairs**: Compared with the Q1 adjustment, the Q3 bond market adjustment was relatively mild, with multiple repairs during the period and did not reach the short - term stop - loss lines of some funds. The adjustment range of the 10 - year Treasury active bond yield since Q3 was less than 20bps, and the adjustment lasted nearly a quarter. In contrast, in Q1, the 10 - year Treasury yield rose about 30bps in more than a month [8][17] - **Performance Assessment and Market Expectations**: The bond market has been volatile this year, especially the performance of bond funds focusing on the duration strategy was significantly weaker than last year. As the fourth quarter is a traditional window for bond market pre -emption and repair, from the perspective of achieving the annual performance assessment, bond funds may not significantly reduce their duration. As of September 14, the median yield of the whole - market bond funds this year was 1.21%, significantly lower than last year's 3.78% [8][26] - **Limited Strategy Options in a Low - interest - rate Environment**: The current bond market is in a low - interest - rate environment, with limited market strategy capacity and options. Public - offering funds have to extend the duration to obtain coupons. Institutions such as wealth management and bank self - operation also have a demand for long - duration bond allocations. As of August this year, the net financing proportion of long - term credit bonds rose to about 33%, a record high [8][33] - **Lack of Massive Redemption Pressure**: Institutions usually conduct continuous and large - scale redemptions of long - term bonds only when the bond market shows obvious "negative feedback" characteristics. A normal market adjustment of general amplitude may not trigger large - scale redemptions and re - allocation of redeemed assets. The current bond market is slowly oscillating and correcting, without triggering widespread market panic [8][34]
