1. Report Industry Investment Rating No information about the industry investment rating is provided in the given content. 2. Core Viewpoints of the Report - In November 2025, the overall bond market weakened, especially the ultra - long end, and the decline in the willingness of trading desks to increase interest - rate bonds may be the core factor for the market adjustment. The adjustment of ultra - long bonds in November may be more affected by the sentiment of trading desks, with relatively limited relation to issues such as bank book interest - rate risks. [3][12] - The bond leverage ratio decreased slightly in November, with the securities company's leverage ratio rising but the product account leverage ratio falling. [4][53] 3. Summary by Related Catalogs 3.1 11 - month Interest - rate Bond Custody Increased Significantly but Certificates of Deposit Had Net Repayment, and the Bond Custody Scale Rose Slightly - In November, the total bond custody scale increased by 147.98 billion yuan month - on - month, an increase of 16.75 billion yuan compared with October. Interest - rate bond custody increments increased by nearly one trillion yuan compared with the previous month, and the custody increments of treasury bonds, local bonds, and policy - financial bonds all increased significantly. Due to the increase in the issuance scale of medium - term notes, the credit - bond custody increment also increased, and the custody scale of commercial bank bonds turned from a decline to an increase. However, the custody volume of inter - bank certificates of deposit changed from an increase of 721.4 billion yuan last month to a decrease of 385.7 billion yuan, significantly dragging down the overall bond custody scale. [3][10] 3.2 The Decline in the Willingness of Trading Desks to Increase Interest - rate Bonds May Be the Core Factor for the Market Adjustment in November 3.2.1 Generalized Funds - In November, the bond custody scale of generalized funds increased by 22.16 billion yuan month - on - month, a decrease of 82.29 billion yuan compared with the previous month. They mainly changed from increasing 77.12 billion yuan of inter - bank certificates of deposit last month to reducing 950 million yuan. In addition, they increased their holdings of financial bonds, local bonds, and medium - term notes on the Clearstream, but also increased their reduction of commercial bank bonds, policy - financial bonds, and enterprise bonds, and changed to reducing treasury bonds and inter - bank certificates of deposit. [18] 3.2.2 Securities Companies - In November, the bond custody volume of securities companies changed from an increase of 13.48 billion yuan last month to a decrease of 14.21 billion yuan, mainly due to the reduction of treasury bonds, policy - financial bonds, and financial bonds on the Clearstream, a decrease in the increase of local bonds, and an increase in the reduction of inter - bank certificates of deposit and commercial bank bonds. However, they increased their holdings of medium - term notes and credit - asset - backed securities and increased their holdings of short - term commercial paper. [26] 3.2.3 Insurance Companies - In November, the bond custody volume of insurance companies changed from a decrease of 450 million yuan last month to an increase of 2.85 billion yuan. They slightly increased their holdings of treasury bonds and inter - bank certificates of deposit and increased their holdings of financial bonds and medium - term notes on the Clearstream, but the increase in local bonds decreased, and the reduction of commercial bank bonds increased. [30] 3.2.4 Overseas Institutions - In November, the bond custody scale of overseas institutions decreased by 11.67 billion yuan month - on - month, and the decline was 6.26 billion yuan larger than the previous month. They mainly changed to reducing treasury bonds, increased their reduction of inter - bank certificates of deposit, but slightly increased their holdings of policy - financial bonds. [32] 3.2.5 Other Institutions - In November, the bond custody volume of other institutions including the central bank increased by 57.46 billion yuan month - on - month, and the increase was 21.9 billion yuan larger than the previous month. They increased their holdings of treasury bonds, changed to increasing policy - financial bonds, but the increase in local bonds decreased and changed to reducing inter - bank certificates of deposit. The structural changes in the custody data may be due to the fact that the proportion of treasury bonds in the repurchase of reverse repurchase targets increased. [37] 3.2.6 Commercial Banks - In November, the bond custody scale of commercial banks changed from a decrease of 25.14 billion yuan last month to an increase of 78.3 billion yuan. They mainly increased their holdings of local bonds and financial bonds on the Clearstream, increased their holdings of treasury bonds, policy - financial bonds, and medium - term notes, but increased their reduction of inter - bank certificates of deposit and changed to reducing short - term commercial paper and credit - asset - backed securities. If the impact of outright repurchase is considered, the banks' increase in holdings of treasury bonds and local bonds further increased. [44] 3.2.7 Credit Unions - In November, the bond custody scale of credit unions changed from a decrease of 2.06 billion yuan last month to an increase of 980 million yuan. They mainly increased their holdings of treasury bonds, increased their holdings of local bonds and financial bonds on the Clearstream, decreased their reduction of policy - financial bonds, but decreased their increase of inter - bank certificates of deposit. [46] 3.3 The Bond Leverage Ratio Decreased Slightly in November, with the Securities Company's Leverage Ratio Rising but the Product Account Leverage Ratio Falling - Affected by the increase in the bond custody scale and the decrease in the scale of institutional funds borrowed, the bond market leverage ratio decreased by 0.2 percentage points month - on - month to 107.2% in November, still at a relatively low level. [4][53] - Among them, the commercial bank's leverage ratio decreased by 0.2 percentage points month - on - month to 103.3%, and the non - bank institution's leverage ratio decreased by 0.3 percentage points month - on - month to 117.0%. In non - bank institutions, the securities company's leverage ratio increased by 11.5 percentage points month - on - month to 231.4%, reaching a new high since 2020, while the leverage ratio of insurance and non - legal person products decreased by 0.3 percentage points month - on - month to 113.7%, still at a relatively low level in the past three years.
