Investment Rating of the Report There is no information provided regarding the industry investment rating in the report. Core Viewpoints of the Report The report analyzes the bond custody data for July 2025, indicating that the total bond custody increased month - on - month, with different trends among various bond types and institutions. The leverage ratio of the bond market decreased month - on - month due to the seasonal reduction of the repurchase bond balance [1][2][3]. Summary by Directory 1. Bond Custody Total and Structure - The total bond custody increased month - on - month. As of the end of July 2025, the combined bond custody of China Central Depository & Clearing Co., Ltd. (CCDC) and Shanghai Clearing House was 173.03 trillion yuan, with a net monthly increase of 1.74 trillion yuan, 0.45 trillion yuan more than the month - on - month increase at the end of June [1][10]. - The custody of interest - rate bonds, credit bonds, and financial bonds increased month - on - month, while the custody of inter - bank certificates of deposit (ICDs) decreased. In July 2025, the custody of interest - rate bonds was 118.91 trillion yuan, accounting for 68.72% of the inter - bank bond market custody, with a net increase of 1.51 trillion yuan; the custody of credit bonds was 18.69 trillion yuan, accounting for 10.80%, with a net increase of 0.18 trillion yuan; the custody of non - policy financial bonds was 12.78 trillion yuan, accounting for 7.39%, with a net increase of 0.41 trillion yuan; the custody of ICDs was 20.74 trillion yuan, accounting for 11.99%, with a net decrease of 0.37 trillion yuan [1][10]. 2. Bond Holder Structure and Changes 2.1 Changes in Custody by Institution Month - on - Month - The custody of major bonds by various institutions in the bond market showed differentiation this month. Allocation accounts increased their custody, while trading accounts and overseas institutions decreased theirs. Specifically, policy banks, insurance institutions, and credit unions increased their holdings of major bonds across the board; commercial banks increased their holdings of major interest - rate and credit products but continued to reduce their holdings of ICDs; securities companies increased their holdings of ICDs but reduced their holdings of major interest - rate and credit products; non - legal entity products continued to increase their holdings of major credit products but reduced their holdings of major interest - rate products and ICDs; overseas institutions continued to reduce their holdings of major bonds across the board [2][24]. - In July, the "anti - involution" policy boosted the equity and commodity markets. Under the influence of factors such as the stock - bond seesaw, the bond market significantly corrected. Trading accounts such as securities and broad - based funds quickly took profits and sold, while allocation accounts such as commercial banks and insurance companies bought significantly, acting as a "stabilizer" for the bond market [24]. 2.2 Changes in Custody by Bond Type Month - on - Month - Treasury bond custody continued to increase this month, with commercial banks being the main buyers [2][26]. - Local government bond custody continued to increase this month, and commercial banks continued to significantly increase their holdings [2][26]. - Policy - financial bond custody continued to increase this month, with commercial banks being the main buyers [2][26]. - ICD custody continued to decrease this month, with commercial banks being the main sellers. The continuous decline in ICD custody was mainly due to the slowdown in issuance and relatively large maturity of existing bonds [2][26]. - Corporate bond custody continued to decrease this month, with non - legal entity products being the main sellers [2][29]. - Medium - term note custody continued to increase this month, and non - legal entity products continued to significantly increase their holdings [2][29]. - Short - term and super - short - term financing custody turned to an increase this month, with commercial banks being the main buyers [29]. - Non - publicly - oriented instrument custody continued to decrease this month, with non - legal entity products being the main sellers [30]. 2.3 Holder Structure of Major Bonds - As of the end of July 2025, the holder structure of major bonds varied. For example, commercial banks were the largest holders of treasury bonds, local government bonds, and policy - financial bonds, while non - legal entity products were the largest holders of medium - term notes, short - term and super - short - term financing, and ICDs [33][34][37]. 3. Observation of Bond Market Leverage Ratio - The balance of bonds to be repurchased decreased seasonally, and the bond market leverage ratio decreased month - on - month. As of the end of July 2025, the estimated balance of repurchase - style pledged repos was 110,279.78 billion yuan, a decrease of 11,233.91 billion yuan month - on - month. The leverage ratio was 106.81%, a decrease of 0.83 percentage points month - on - month and 0.24 percentage points year - on - year [3][48].

Group 1 - The central bank maintains a relatively loose liquidity stance, with market institutions expecting no tightening of funds in August [1][2] - The liquidity gap in August is estimated to be around 200 billion yuan, indicating manageable pressure [1] - Government bond issuance is expected to peak in August, with net financing around 1.2 trillion yuan, contributing to the liquidity landscape [2] Group 2 - The banking sector is anticipated to face increased pressure due to high government bond supply, with monthly net financing potentially reaching 1.5 to 1.6 trillion yuan [2] - The central bank may utilize various liquidity management tools, including OMO, MLF, and reverse repos, to stabilize the market [2] - Recent economic data does not support a shift in monetary policy, reinforcing the expectation of stable liquidity conditions [2][3] Group 3 - Risks to liquidity are more influenced by institutional market behavior rather than fiscal and monetary policies, highlighting the need to monitor bank liabilities and lending capabilities [3] - The decline in deposit rates and the siphoning effect from the equity market may exacerbate deposit outflows, particularly affecting joint-stock banks [3] - The recent reduction in leverage in the bond market is expected to help control the sensitivity of institutions to fluctuations in funding rates [3]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report Under the resonance of multiple negative factors such as the rise in risk preference, the sharp rise in the equity and commodity markets, and the central bank's net withdrawal in the open - market operations disturbing the capital price, the bond market fluctuated violently this week. The selling behavior of funds is particularly worthy of attention. The scale of funds' net selling on Thursday and Friday was second only to the redemption tides in late August and early October last year. The performance of bond funds was poor, with over 40% of pure interest - rate bond funds recording negative returns in the past three months. Continued attention should be paid to changes in market risk preference and fund redemption situations [10]. 3. Summary According to Relevant Catalogs 3.1 Overall Sentiment - The bond market vitality index increased, mainly due to the rise in the turnover rate of ultra - long bonds. As of July 25, the bond market vitality index rose 6 pcts to 37% compared with July 18, and the 5D - MA rose 5 pcts to 45% [11]. - Indicators of rising bond market vitality included the trading volume of the active 10Y CDB bond / the balance of 9 - 10Y CDB bonds (the rolling two - year quantile rose from 42% to 72%), the 30Y treasury bond turnover rate (the rolling two - year quantile rose from 16% to 71%), and the median duration of medium - and long - term pure bond funds (the rolling two - year quantile rose from 99.3% to 99.7%) [13]. - Indicators of falling bond market vitality included the excess level of the inter - bank bond market leverage ratio compared with the average of the past 4 years (the rolling two - year quantile dropped from 20% to 5%) and the implied tax rate of 1 - 10Y CDB bonds (the rolling two - year quantile dropped from 57% to 21%) [14]. 3.2 Institutional Behavior 3.2.1 Buying and Selling Strength and Bond Selection - In terms of overall buying and selling strength, the order of net buying strength in the cash bond market this week was large banks > insurance > wealth management > other products > money market funds > overseas institutions and others, and the order of net selling strength was funds > securities firms > joint - stock banks > city commercial banks. For ultra - long bonds, the order of net buying strength was insurance > rural commercial banks > city commercial banks > wealth management, and the order of net selling strength was funds > securities firms > large banks > joint - stock banks > other products [22]. - Different institutions had different main bond types. Large banks focused on 1 - 3Y interest - rate bonds and credit bonds; rural commercial banks focused on 5 - 10Y interest - rate bonds and 1 - 3Y other bonds; insurance focused on interest - rate bonds over 10Y and 7 - 10Y credit bonds; funds focused on interest - rate bonds within 1Y; wealth management focused on certificates of deposit and interest - rate bonds within 3Y; other products focused on certificates of deposit [26]. 3.2.2 Trading Portfolio - As of July 25, the median duration of the full - sample medium - and long - term pure bond funds increased by 0.21 years to 4.38 years compared with July 18.

However, the net purchase of 7 - 10Y and over 10Y cash bonds was higher than the same period in previous years [70]. - **Insurance**: This year, the net purchase of cash bonds and its ratio to premium income were significantly higher than in previous years, mainly due to the sufficient supply of ultra - long - term government bonds. As of July 25, the ratio of the cumulative net purchase of cash bonds to the cumulative issuance of government bonds over 10Y was 27.34%, lower than 35.14% at the end of July last year [81]. - **Wealth management**: From June to July, the cumulative net purchase of cash bonds continued to rise, especially for bonds over 10Y.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Since 2021, the logic of the "asset shortage" in the bond market is not applicable this year. Instead, the bond market presents a "liability shortage." The liability gap and structure are the main lines of bond market trading this year [2][5][12]. - The bond market is unlikely to rise trend - wise. Only continuous negative carry can drive the trend - wise correction of long - term interest rates. The probability of a tightening of capital prices in the second quarter is not high, and the market interest rate is expected to fluctuate in the range of 1.5% - 1.6% [2][8][22]. - The bond market has no obvious odds recently. A 10bp positive carry can boost the inter - bank bond market leverage ratio by about 0.1 - 0.2 percentage points. The current positive carry amplitude is insufficient, restricting the market's enthusiasm for leveraging [2][8][30]. - It is recommended to allocate when the 10 - year Treasury bond yield is above 1.65% and the 30 - year Treasury bond yield is above 1.9%. Institutions with stable liabilities can appropriately focus on the coupon opportunities of credit bonds with a term of more than 3 years [2][8][34]. 3. Summary by Related Catalogs 3.1 From "Asset Shortage" to "Liability Shortage", Bond Market Volatility - Before 2024, the "asset shortage" was the main line of the bond market. Due to the downward pressure on the real estate industry and the establishment of the regulatory red line for local implicit debt, credit expansion was constrained. Since this year, with the adjustment of the social financing structure and the relative stability of credit, the "asset shortage" is no longer the main contradiction. The supply of government bonds has increased, and the social financing growth rate has rebounded to 8.7% in April [5][12]. - While the asset supply has increased, the bond market faces a "liability shortage." The central bank's attitude is not the only source of liability pressure. Currently, the market style is more trading - oriented, lacking stable - liability configuration forces. Insurance's premium income growth has declined significantly this year, and its trading attribute has increased; wealth management is undergoing rectification, reducing the allocation of less - liquid credit bonds; public funds have a strong wait - and - see sentiment [8][19]. 3.2 Difficulty in Trend - wise Market, Focus on Curve Trading Opportunities - The bond market is difficult to rise trend - wise. In a relatively stable fundamental situation, only continuous negative carry can drive the trend - wise correction of long - term interest rates. The current fundamental situation is relatively stable, but the real interest rate is high, and there is still uncertainty in the fundamental recovery. The probability of a tightening of capital prices in the second quarter is not high [8][22]. - The bond market has no obvious odds recently. Although the bond market has returned to the positive carry range, the amplitude is insufficient, restricting the market's enthusiasm for leveraging. A 10bp increase in carry can increase the inter - bank bond market leverage ratio by 0.14 and 0.21 percentage points respectively. Since May, the average monthly inter - bank bond market leverage ratio has increased by about 0.2 percentage points compared with April [8][30]. - Before the bond market shows sufficient odds, it is difficult to have a trend - wise market. It is expected that the 10 - year Treasury bond yield will fluctuate around 1.6% - 1.7%. It is recommended to capture trading opportunities along the yield curve. Institutions with stable liabilities can focus on the coupon opportunities of credit bonds with a term of more than 3 years [8][34].
