1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report This week, the bond market lacked a clear trading direction, and institutional behaviors remained stable overall. Large banks continued to focus on net - buying short - term bonds within 3 years, but the intensity declined. Funds showed a strong preference for credit bonds. Rural commercial banks took advantage of the bond market adjustment to make small - scale purchases. Looking ahead, the year - end "rush to allocate" seasonal market may not occur due to various constraints on banks and insurance companies [11]. 3. Summary by Directory 3.1 Overall Sentiment: Slight Increase in Bond Market Vitality Index - As of November 7, the bond market vitality index rose 4 pcts to 22% compared to October 31, and the 5D - MA increased 3 pcts to 25% [1][12]. - Upward indicators included the trading volume of the active 10Y China Development Bank bond / balance of 9 - 10Y China Development Bank bonds (rolling two - year percentile rose from 42% to 69%) and the 30Y Treasury bond turnover rate (rolling two - year percentile rose from 20% to 35%) [1][13]. - Downward indicators included the implied tax rate of the 10 - year China Development Bank bond (reverse) (rolling two - year percentile remained at 7%), the excess level of the inter - bank bond market leverage ratio compared to the average of the past 4 years (rolling two - year percentile rose from 61% to 18%), and the median duration of medium - and long - term pure bond funds (rolling two - year percentile dropped from 84.0% to 82.1%) [1][14][16]. 3.2 Institutional Behavior: Continued Volatility in the Bond Market, Overall Stability in Institutional Behaviors 3.2.1 Buying and Selling Intensity and Bond Selection: Large Banks Continuously Buy Short - Term Bonds, Funds Focus on Credit Bonds - This week, the order of net buying intensity in the cash bond market was: other products > insurance > wealth management > large banks > money market funds > others > funds > rural financial institutions > foreign - funded banks.

The median durations of high - performing interest - rate bond funds and credit bond funds decreased by 0.72 years and - 0.01 years respectively, reaching 1.90 years and 0.91 years [38][42]. 3.2.3 Allocation Portfolio: Large Banks Concentrate on Buying Interest - Rate Bonds within 3 Years - **Increased Primary Subscription Demand for Treasury Bonds and Policy - Financial Bonds, and Increased Demand for Ultra - Long Bonds**: This week, the weighted average full - market multiples of treasury bonds and policy - financial bonds continued to rise from 2.93 to 3.13 times and from 3.21 to 3.25 times respectively.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - This week, the trading behavior of various institutions was generally subdued. Only large banks showed a firm willingness to buy interest rate bonds with maturities of less than 3Y and 5 - 7Y, while funds were keen on buying credit bonds with maturities of less than 3Y. Large banks' cumulative net purchase of interest rate bonds reached 141.4 billion yuan this week, the highest weekly net purchase scale in the past year. Funds' net purchase of credit bonds was 3.4 billion yuan, the third - highest since August [10]. - Looking ahead, attention should be focused on the recovery of allocation power. For banks, the easing of government bond supply pressure in the fourth quarter may boost large banks' purchasing power. For insurance companies, after the reduction of product predetermined interest rates, the slowdown of liability - side expansion may be a long - term trend, and the "rush to allocate" situation in previous years may not be repeated in the fourth quarter [10]. Summary by Directory 1. Overall Sentiment: Bond Market Vitality Index Declined Slightly - The bond market vitality index was compiled based on the historical quantile levels of bond market leverage ratio, turnover rate, bond fund duration, and implied tax rate of China Development Bank bonds since 2022 and their correlation coefficients with bond market trends. As of October 24, the bond market vitality index dropped 4 pcts to 15% compared with October 17, and the 5D - MA dropped 1 pct to 24% [11]. - Indicators of rising bond market vitality included the implied tax rate of 10 - year China Development Bank bonds (inverse) and the excess level of the inter - bank bond market leverage ratio compared with the average of the past four years. Indicators of declining vitality included the trading volume of active 10Y China Development Bank bonds / the balance of 9 - 10Y China Development Bank bonds, the turnover rate of 30Y treasury bonds, and the median duration of medium - and long - term pure bond funds [13][14]. 2. Institutional Behavior: Current Institutional Behavior is Generally Subdued, Pay Attention to Allocation Power in the Future 2.1. Buying and Selling Strength and Bond Type Selection: Large Banks Continuously Buy Short - Term Bonds, Funds Focus on Credit Bonds - In the current bond market, the order of net buying strength was money market funds > funds > large banks > wealth management > securities firms > others > insurance > other product types > foreign banks, and the order of net selling strength was joint - stock banks > city commercial banks > rural financial institutions. For ultra - long - term bonds (bonds with a maturity of more than 15Y), the order of net buying strength was insurance > other product types > funds > wealth management > others, and the order of net selling strength was large banks > city commercial banks > joint - stock banks > rural commercial banks > securities firms > foreign banks [22]. - On different trading days from October 20 to 24, the buying and selling behaviors of various institutions varied. For example, on October 20, when the bond market fell across the board, large banks mainly bought interest rate bonds with maturities of less than 1Y, and funds mainly bought 7 - 10Y interest rate bonds, 1 - 3Y credit bonds, etc. [22][23]. - Based on the net purchase volume of bonds and historical quantiles, the main bond types of various institutions were as follows: large banks focused on interest rate bonds with maturities of less than 1Y, 1 - 3Y, and 5 - 7Y; rural commercial banks focused on other bonds with maturities of 3 - 5Y; insurance focused on 1 - 3Y credit bonds; funds focused on 1 - 3Y credit bonds; wealth management focused on interest rate bonds with maturities of less than 1Y and 1 - 3Y; other product types focused on credit bonds with maturities of less than 1Y [28]. 2.2.

Therefore, the constraints on large banks' bond allocation may ease. In terms of short - term treasury bond trading, large banks' net buying of 1Y and below treasury bonds has been higher than that of the same period last year since June, and the cumulative net buying of 1 - 3Y treasury bonds as of October 24 has reached 845.3 billion yuan [63]. - **Rural Commercial Banks: Weak Bond - Buying Power, Emphasizing Long - Term Bonds over Short - Term Bonds**: This year, the cumulative net purchase of bonds by rural commercial banks has been significantly weaker than in previous years, mainly due to the weak net purchase of short - term bonds with maturities of less than 1Y. However, the net purchase of 7 - 10Y and 10Y + bonds has been significantly higher than in previous years [76]. - **Insurance: The Acceleration of Government Bond Issuance Helps Insurance Deploy Ultra - Long - Term Bonds**: This year, the net purchase of bonds by insurance companies has been significantly higher than in previous years, mainly due to the strong purchase of ultra - long - term bonds with maturities of more than 10Y. As of October 24, the ratio of cumulative net bond purchases to cumulative premium income and the ratio of cumulative net bond purchases to the cumulative issuance of 10Y + government bonds were both higher than those at the end of October last year [85]. - **Wealth Management: Extending Duration in the Secondary Market**: Since June, the cumulative net purchase of bonds by wealth management products has continued to rise, significantly higher than the levels of the past three years. As of October 24, the cumulative net purchase of 10Y + bonds by wealth management products has reached 16.59 billion yuan [93]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In the current chaotic bond market, trading desks are actively exploring structural trading opportunities, especially showing high enthusiasm for the previously oversold Tier 2 and perpetual bonds. Although the allocation desks have not yet formed a systematic承接 strength, the pressure restricting the allocation power is easing, and the承接 strength may improve marginally [10]. - Fund sentiment has stabilized, with a return to net buying of various bond types. However, overall, the enthusiasm for interest - rate bonds is not high, mainly focusing on steadily increasing the allocation of credit bonds and Tier 2 and perpetual bonds [10]. - Attention should be paid to the承接 strength of large - scale banks and insurance companies. The constraints on large - scale banks' bond allocation may ease, and the bond market has adjusted to a level with allocation value, which is more attractive to insurance companies [10][11]. 3. Summary by Relevant Catalogs 3.1 Overall Emotion - As of October 17, the bond market vitality index increased by 21 pcts to 21% compared to October 10, and the 5D - MA increased by 19 pcts to 25%. The warming indicators include the implied tax rate of the 10 - year China Development Bank bond (inverse), the trading volume of the active 10Y CDB bond / the balance of 9 - 10Y CDB bonds, the leverage ratio of the inter - bank bond market, and the turnover rate of the 30Y Treasury bond. The cooling indicator is the median duration of medium - and long - term pure bond funds [1][12][13]. 3.2 Institutional Behavior 3.2.1 Buying and Selling Strength and Bond Type Selection - In the current bond market, the order of net buying strength is other product types > insurance > funds > rural finance > money market funds > securities firms > wealth management > city commercial banks, and the order of net selling strength is large - scale banks > joint - stock banks > foreign banks. For ultra - long bonds (bonds with a maturity of over 15 years), the order of net buying strength is insurance > funds > securities firms > others > wealth management > foreign banks, and the order of net selling strength is large - scale banks > other product types > city commercial banks > joint - stock banks > rural commercial banks [23]. - On different trading days from October 13 to October 17, the buying and selling behaviors of various institutions showed different characteristics. For example, on October 13, funds significantly increased their net buying of long - term and ultra - long - term interest - rate bonds; on October 14, funds slightly net sold interest - rate bonds of all maturities but maintained net buying of Tier 2 and perpetual bonds and credit bonds within 3 years [23][24]. - Currently, the main bond types of various institutions are as follows: large - scale banks and rural commercial banks have no obvious main bond types; insurance mainly focuses on interest - rate bonds with a maturity of less than 1 year; funds mainly focus on 1 - 3 - year credit bonds; wealth management mainly focuses on 1 - 3 - year credit bonds; other product types mainly focus on credit bonds with a maturity of less than 1 year [2][26]. 3.2.2 Trading Desk - As of October 17, the mean and median durations of the full - sample medium - and long - term pure bond funds decreased by 0.18 years and 0.23 years respectively compared to October 10, reaching 4.09 years and 3.82 years.

Although the cumulative net buying scale of short - term Treasury bonds by large - scale banks since June has increased, it is still far lower than the same period in 2024. The net buying scale of 1 - 3Y Treasury bonds has been declining since August [61]. - **Rural commercial banks**: The cumulative net buying scale of rural commercial banks this year is significantly weaker than in previous years, mainly due to the weak net buying strength of short - term bonds within 1 year. However, the net buying strength of 7 - 10Y and over 10Y bonds is significantly higher than in previous years [73]. - **Insurance companies**: The net buying strength of insurance companies for bonds this year is significantly higher than in previous years, especially for ultra - long bonds over 10 years. As of October 17, the ratio of the cumulative net buying of bonds to the cumulative premium income and the ratio of the cumulative net buying of bonds to the cumulative issuance scale of over 10Y government bonds are both higher than the end of October last year. The strong performance of 30Y local government bonds and railway bonds this week may reflect the improvement of insurance companies' bond - allocation strength [80]. - **Wealth management**: Since June, the cumulative net buying scale of wealth management products in the secondary market has continued to rise, significantly higher than the past three years. As of October 17, the cumulative net buying of over 10Y bonds by wealth management products this year reached 16.3 billion yuan [85]. 3.3 Asset Management Product Tracking - Since October, the scales of bond funds and equity funds have both decreased month - on - month, with equity funds experiencing a larger decline.

In terms of bond fund performance, the net values of most credit and interest - rate bond funds continued to rise in the past week, with pure interest - rate bond funds having a larger increase. Most interest - rate and credit bond funds recorded negative returns in the past three months [5][89][90].

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.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Fund's "chasing up" behavior has become more rational, and the duration risk may be gradually released. The overall "chasing up and selling down" behavior of funds is more moderate. The weekly net purchase of interest rate bonds by funds reached a new high since July, but the net purchase of interest rate bonds over 10Y was relatively low, which may gradually release the risk of supply - demand mismatch in ultra - long bonds [10]. Summary by Directory 1. Overall Sentiment: Bond Market Vitality Index Declined Slightly - As of September 19, the bond market vitality index decreased by 5 pcts to 13% compared with September 12, and the 5D - MA decreased by 13 pcts to 17%. The rising indicators of bond market vitality include the implied tax rate of the 10 - year CDB bond (inverse), and the cooling indicators include the trading volume of the active 10Y CDB bond / the balance of 9 - 10Y CDB bonds, the leverage ratio of the inter - bank bond market, the median duration of medium - and long - term pure bond funds, and the turnover rate of the 30Y Treasury bond [2][11][13]. 2. Institutional Behavior: Funds Cautiously Go Long, Rural Commercial Banks Increase Selling 2.1. Buying and Selling Strength and Bond Type Selection - The order of net buying strength in the current bond market this week is: funds > other product types > insurance > wealth management > large banks > others > foreign - funded banks > money market funds > securities firms. The order of net selling strength is: city commercial banks > rural financial institutions > joint - stock banks. For ultra - long bonds (bonds over 15Y), the order of net buying strength is: insurance > securities firms > wealth management > funds > foreign - funded banks, and the order of net selling strength is: large banks > city commercial banks > joint - stock banks > rural commercial banks > other product types > others. - The main bond types of various institutions are: large banks have no obvious main bond types; rural commercial banks focus on credit bonds over 10Y; insurance focuses on 3 - 5Y credit bonds; funds focus on 1 - 3Y, 3 - 5Y, and 7 - 10Y interest rate bonds; wealth management focuses on interest rate bonds within 1Y and 3 - 5Y credit bonds; other product types focus on 3 - 5Y interest rate bonds [3][20]. 2.2. Trading Portfolio - As of September 19, the median duration of the full - sample medium - and long - term pure bond funds increased by 0.01 years compared with September 12. Among them, the median durations of pure interest rate bond funds, interest rate bond funds, and credit bond funds increased by 0.13 years, 0.14 years, and decreased by 0.01 years to 5.17 years, 4.86 years, and 3.71 years respectively.

Allocation Portfolio - **2.3.1. The primary subscription demand for Treasury bonds and policy - financial bonds increased, and the demand for ultra - long bonds increased**: This week, the primary subscription demand for Treasury bonds and policy - financial bonds increased, and the demand for ultra - long bonds also increased. The weighted average full - market multiples of Treasury bonds and policy - financial bonds increased from 3.04 times and 2.71 times to 3.39 times and 3.00 times respectively. Among them, the weighted average full - market multiples of Treasury bonds and policy - financial bonds over 10Y increased from 3.37 times and 2.12 times to 3.63 times and 3.34 times respectively [52]. - **2.3.2. Large banks: The increase in the supply of ultra - long bonds may restrict their secondary - market承接 capacity**: Since this year, the issuance scale of ultra - long - term government bonds has been larger and the average issuance term has been longer. Large banks may face the pressure of interest rate risk indicator assessment after continuous purchase, which restricts their secondary - market承接 capacity. In terms of short - term Treasury bond trading, large banks increased their net purchase of Treasury bonds within 1Y since June, but the cumulative net purchase scale this year is still far lower than that of the same period in 2024 and higher than that in 2023. The net purchase of 1 - 3Y Treasury bonds was strong from May to July and then declined. As of September 19, the cumulative net purchase of 1 - 3Y Treasury bonds this year was 684.1 billion yuan [57]. - **2.3.3. Rural commercial banks: Weak bond - buying strength, emphasizing long - term bonds and de - emphasizing short - term bonds**: The cumulative net purchase of bonds by rural commercial banks this year is significantly weaker than in previous years, mainly due to the weak net purchase of short - term bonds within 1Y. As of September 19, rural commercial banks have accumulated a net sale of 568 billion yuan of bonds within 1Y this year.
