机构行为精讲系列之四：银行资负及配债行为新特征

1. Report Industry Investment Rating No information provided in the given content. 2. Core Views of the Report - The report comprehensively analyzes commercial banks' bond allocation, regulatory frameworks, asset - liability structures, and bond investment behaviors. Low - interest rates may lead to an increase in the proportion of OCI accounts, amplifying large banks' trading behaviors. Investors should pay attention to the "buy short, sell long" seasonal characteristics of large banks' bond investments and trading opportunities. Rural commercial banks' bond investment behaviors also show new features, and investors can make decisions based on their seasonal characteristics and key trading varieties [4][9][10]. 3. Summary According to the Table of Contents 3.1 Commercial Banks' Bond Allocation Overview - As of the end of 2024, commercial banks' bond allocation reached 89.70 trillion yuan, accounting for 50.70% of China's bond market custody balance. They prefer interest - rate bonds, with interest - rate bonds accounting for 82.7% (74.0 trillion yuan), followed by credit bonds (11.3%, 10.2 trillion yuan) and certificates of deposit (6.0%, 5.4 trillion yuan). Since 2024, the growth rate of commercial banks' bond allocation has first declined and then increased, which is highly correlated with the supply rhythm of government bonds [14][16]. 3.2 Bank Main Regulatory Frameworks: Macro - Prudential + Micro - Supervision, Multi - Dimensional and Multi - Level - Central Bank Macro - Prudential Assessment: Focuses on "broad credit" and interest - rate pricing. The assessment objects include various banking financial institutions, divided into three categories. It contains seven major indicators, and the assessment results are divided into A, B, and C grades, with different incentives and constraints for each grade [21][24]. - Financial Regulatory Bureau Micro - Indicator Assessment - Capital Measures and Bank Ratings: Centered on capital adequacy ratio, the 2023 "Commercial Bank Capital Management Measures" guide banks to form an interest - rate bond - based investment structure. Bank ratings have additional requirements for systemically important banks and global systemically important banks [28][29][34]. - Liquidity Risk Assessment Indicators: Aim to guide banks to increase stable liabilities and hold high - quality liquid assets. Mainly focus on LCR, NSFR, HQLAAR, and LMR, with different applicable scopes. The assessment pressure mainly lies in the quarter - end compliance pressure of NSFR [46][48]. - Duration Indicators: A "hard constraint" for large banks to extend bond investment duration. When the economic value change of state - owned large banks exceeds 15% of their primary capital, regulatory assessment is required [49]. 3.3 Bank Asset - Liability Structure - Liability Structure - Deposit Structure: Deposits account for about 70% of liabilities. Personal deposits exceed corporate deposits, and non - bank inter - bank deposits account for a relatively stable proportion. The weighted deposit term has been lengthening. Since 2024, large banks' dependence on inter - bank liabilities has increased, and the cost of liabilities has been declining rapidly [55][57][70]. - Inter - bank Liabilities: Since 2024, high - interest deposit - soliciting behaviors have been prohibited, and large banks' inter - bank liability ratio has increased to around 15%. After the optimization of non - bank inter - bank current deposit pricing in late 2024, large banks rely more on inter - bank certificates of deposit to supplement liabilities [63][65]. - Asset Structure - Loan Structure: Loans are the main asset, but the growth rate of household and corporate loans has been declining since 2023, and the loan term has been lengthening. The loan term has shown a trend of "first lengthening, then shortening, and then lengthening" since 2015 [73][77][84]. - Inter - bank Assets: The proportion of inter - bank assets has been declining, and the term has been lengthening since 2022. Among them, the proportion of lending funds has remained stable, while the proportions of placed - with - banks and reverse - repurchase assets have declined [87][91]. 3.4 Bank Bond Investment Behaviors - Bond Allocation Varieties: Mainly interest - rate bonds, with interest - rate bonds > certificates of deposit > credit bonds in terms of EVA comparison [4]. - Financial Investment Account Structure: The OCI account is both offensive and defensive and is more favored by banks in the low - interest rate stage. State - owned banks in the OCI account mainly trade government bonds, while small and medium - sized banks conduct credit down - grading. In the AC account, government bonds dominate. The TPL account has the strongest trading attribute, with a relatively high proportion of outsourced funds [4]. - Large Banks' High - Frequency Duration of Holdings: Since 2024, the duration pressure has gradually increased, and the characteristic of "buying short and selling long" at the end of the quarter has been strengthened. In 2025, the duration of large banks has continued to lengthen, and the duration pressure may ease after the peak of government bond issuance [4]. 3.5 New Developments: New Features of Large and Small Banks' Investment Behaviors - Large Banks - Buying Bonds: Driven by the central bank's bond - buying, large banks "buy short" and control the short - end pricing. Constrained by duration indicators, the "buy short, sell long" characteristic is strengthened. - Selling Bonds: To meet profit requirements, they sell old bonds to realize floating profits. Facing liquidity pressure, they reduce lending, redeem funds, and then increase bond sales [4]. - Small Banks: In 2025, "small banks' bond - buying" has returned, with a more flexible investment style. Rural commercial banks attach importance to trading in bond investment, with an overall increase in turnover rate. They have pricing power over certain bonds, and their bond - buying peaks usually occur in specific periods. Attention should be paid to the leading signals of rural commercial banks' early - bird actions at the end of the year [7].
