机构行为月报：债市修复期，各类机构在买卖什么？-20251104

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In October, the trading sentiment in the bond market recovered, with the interest rate oscillation range significantly lower than in September. Overall, the trading willingness of funds significantly recovered, while allocation players seized the opportunity to exit the market. The potential for a year - end "rush to allocate" seasonal bond market rally is uncertain, and the restoration of allocation players' strength remains doubtful. The high duration of bond funds also poses risks [1][10][45]. 3. Summary by Directory 3.1 10月：债市修复期，各类机构在买卖什么？ - Market Situation: In October, the trading sentiment in the bond market recovered, and the interest rate oscillation range was significantly lower than in September. The main bond market trend remained unclear, and various factors successively affected the market trend, with the interest rate generally maintaining a range - bound oscillation [10]. - Overall Institutional Behavior: The trading willingness of funds significantly recovered, with the average daily net purchase of spot bonds turning positive for the first time since July, reaching 176 million yuan. The average daily net selling of rural commercial banks increased from 148 million yuan in September to 253 million yuan. Although insurance and large - scale banks maintained net purchases, their average daily net purchase amounts decreased from 182 million yuan to 143 million yuan and from 193 million yuan to 50 million yuan respectively [10]. 3.1.1 大行：全面加大3Y以内短债净买入力度，平衡持仓久期 - Reason for Behavior: After large - scale banks bought long - term treasury bonds and policy - financial bonds in September, they shifted to comprehensively increasing the net purchase of short - term bonds within 3 years in October, possibly to balance the duration of their holdings [16]. - Specific Buying Behavior: In October, large - scale banks further strengthened the net purchase of 1 - 3Y old treasury bonds (the average daily net purchase increased to 6.7 billion yuan). They also significantly increased the net purchase of new and old treasury bonds within 1 year and new 1 - 3Y treasury bonds (the average daily net purchase increased to 1.6 billion yuan, 5 billion yuan, and 2.4 billion yuan respectively). The average daily net purchase of 7 - 10Y old treasury bonds and old policy - financial bonds decreased to 400 million yuan and 500 million yuan respectively [17]. - Purchase Rhythm and Annual Data: The peak of large - scale banks' net purchase of treasury bonds within 3 years occurred between the 20th and 28th. After the central bank announced it would resume bond - buying, the scale of large - scale banks' net purchase of short - term bonds declined. From January to October this year, large - scale banks' cumulative net purchase of 1 - 3Y treasury bonds was 88.61 billion yuan, exceeding 78.16 billion yuan in the same period last year; the cumulative net purchase of treasury bonds within 1 year also reached 43.55 billion yuan. The central bank's resumption of bond - buying may not necessarily mean that large - scale banks need to replenish their positions on a large scale in the secondary market, and the positive impact on short - term varieties may converge [20]. 3.1.2 农商行和保险：趁修复之际快速持续卖出 - Rural Commercial Banks: In October, the net selling of rural commercial banks spread from long - term and ultra - long - term to short - term bonds. The selling pressure on 7 - 10Y policy - financial bonds was the greatest throughout the month. They closely followed the interest rate for "buying high and selling low" operations, with the selling intensity significantly greater than the buying intensity. The average daily net selling of long - term and ultra - long - term interest - rate bonds increased from 90 million yuan in September to 700 million yuan, but the net selling intensity was weaker than in June, another repair period [28]. - Insurance Companies: In October, the average daily net selling of 20 - 30Y treasury bonds by insurance companies reached a new high since 2023, with the average daily net selling scale reaching 210 million yuan. The net purchase of 20 - 30Y local government bonds decreased significantly, which is in line with the rule that their purchase volume closely follows the supply volume [33]. 3.1.3 基金：积极参与信用二永票息与国开 - 国债利差策略 - Seeking Spread Trading Opportunities: During the previous bond market adjustment, ultra - long - term bonds, Tier 2 capital bonds, and policy - financial bonds favored by funds generally faced significant selling pressure, opening up spread spaces. In October, funds began to seek spread trading opportunities for these bonds. The buying intensity for 7 - 10Y policy - financial bonds and 7 - 10Y other bonds (mainly Tier 2 capital bonds with a remaining maturity of 2 - 5Y) was the strongest, with the total net purchase scale in the month reaching 6.84 billion yuan and 4.54 billion yuan respectively. They remained cautious about ultra - long - term bonds, with the net purchase of treasury bonds over 10 years only at 1.94 billion yuan throughout the month [38]. - Exploring Short - Term Spread Trading Space: On October 31, the spot bond data showed that the net purchase of 3 - 5Y policy - financial bonds by funds jumped to 970 million yuan. As the positive impact of the central bank's resumption of bond - buying on short - term treasury bonds weakened, funds may start to explore the spread trading space between short - term policy - financial bonds and treasury bonds [38]. - Selecting Coupon Assets: Since there was still no major trend in the bond market, some funds actively selected coupon assets to seek the certainty of coupon income. In October, the total net purchase of credit bonds by funds increased from 1.42 billion yuan in September to 13.26 billion yuan, the highest since July, but still lower than in the second quarter [38]. 3.2 11月：会有年末抢配行情出现吗？ - Uncertainty of Allocation Players' Restoration: The restoration of the bond - allocation strength of rural commercial banks and insurance companies is likely to be limited, and the timing for allocation players to enter the market is more focused on quarterly timing. The year - end "rush to allocate" seasonal bond market rally may not reappear this year [46]. - Uncertainties for Large - Scale Banks: The potential for large - scale banks to undertake bond purchases faces uncertainties such as liability - side instability, profit - taking demands, and pressure on interest - rate risk indicators. Although the supply of ultra - long - term bonds in the fourth quarter is expected to be lower than in the second and third quarters, and the pressure on interest - rate risk indicators is expected to ease, there are still potential uncertainties, including the large - scale maturity of high - interest time deposits in the fourth quarter, the possible acceleration of credit issuance, and the banks' profit - taking demands in the fourth quarter [47]. - High Duration Risk of Bond Funds: The duration of bond funds remains at a historically high level, and their risk - resistance ability is relatively weak. If the official draft of the new regulations on fund sales fees is implemented at the end of the year, or if funds are redeemed by banks and wealth management products for other reasons, there is a possibility of a negative feedback loop due to the concentrated release of duration risk. However, the market currently has limited pricing for this risk, and there may not be many foreseeable negative factors in November. More attention can be paid to whether there will be regulatory and stimulus policy expectations in December [49].
