1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In August, the "stock - bond seesaw" effect was significant. Interest rates first declined and then rose. Credit bond yields generally followed the upward trend of interest - rate bonds. Short - duration varieties were more resistant to decline, while medium - and long - duration ones were weaker. Looking ahead to September, credit bonds still need defensive strategies [1][11][12]. - After the adjustment in August, some bank capital bonds have fallen to show relative value. For example, 3 - year AA and above second - tier capital bonds are oversold, and 4 - 5 - year large - bank capital bonds also have certain value for accounts with different liability characteristics [29][33][37]. 3. Summary According to the Directory 3.1 High - Coupon Short - Term Bonds as Shields, Oversold Perpetual and Second - Tier Capital Bonds as Spears 3.1.1 Credit Bond Defense with Short - and Medium - Duration - In August, the "stock - bond seesaw" effect was prominent. Short - end bonds outperformed long - end ones. Credit bond yields generally rose with interest - rate bonds. Short - duration credit bonds were more resistant to decline, and institutions further shortened the duration to within 3 years. The net buying scale of credit bonds decreased, and the trading activity also declined [1][11][12]. - In September, credit bonds need defense. Bank wealth - management scale usually declines at the end of the quarter, reducing the demand for credit bonds. Credit spreads are at a relatively low level, and institutions will pay more attention to controlling drawdowns when investing in credit bonds [16]. - There are two defensive ideas for credit bonds. One is to select high - coupon individual bonds within 3 years. The other is to appropriately allocate defensive varieties such as 1Y inter - bank certificates of deposit and 2Y commercial financial bonds, which have certain cost - effectiveness compared with medium - and short - term notes of the same term [3][19][22]. 3.1.2 Bank Capital Bonds: Opportunities Arising from Declines - In August, the yields of bank capital bonds generally rose, and spreads widened. After the adjustment, some varieties showed relative value. For example, 3 - year AA and above second - tier capital bonds were oversold, and the yields of 3 - year AA second - tier capital bonds were equivalent to those of 3 - year AA perpetual bonds [28][29][30]. - The yields of 4 - 5 - year large - bank capital bonds rose significantly in August. As the decline deepened, insurance, wealth - management, and other asset - management products increased their allocation. For accounts with stable liability ends, they are still cost - effective coupon assets. For accounts with unstable liability ends, it is recommended to follow the interest - rate bond market for right - side layout [33][36][37]. 3.2 Urban Investment Bonds: Supply Recovery, Short - End and Low - Rating Bonds Resistant to Declines - In August, the net financing of urban investment bonds was positive and increased year - on - year but decreased month - on - month. The issuance of long - duration bonds decreased, and the weighted average issuance interest rate increased. The net financing performance varied by province [39]. - The yields of urban investment bonds generally rose in August. Short - end and low - rating bonds were more resistant to decline, while 10 - year ultra - long - term bonds were the weakest. Credit spreads showed differentiation [45]. - The trading activity of urban investment bonds was not high in August. The proportion of TKN and low - valuation transactions decreased compared with July. Short - duration bonds had an increase in trading volume, while 3 - 5 - year bonds had weaker trading [51]. 3.3 Industrial Bonds: Supply Contraction, Yields Generally Rising - In August, the issuance and net financing of industrial bonds decreased year - on - year. The issuance sentiment weakened, and the issuance proportion of short - duration bonds within 1 year decreased, while the proportion of 1 - 3 - year bonds increased. The issuance interest rates rose across the board, with medium - and long - duration bonds having a larger increase [54]. 3.4 Bank Capital Bonds: Net Financing Turns Negative, Trading Sentiment is Weak No detailed content provided in the given text for this part other than the title. It can be inferred from the previous content that in August, the net financing of bank capital bonds may have turned negative, and the trading sentiment was weak as the yields generally rose and spreads widened, and the relative performance was inferior to that of general credit bonds [28].

1. Report Industry Investment Rating No relevant content provided in the report. 2. Core Viewpoints of the Report - Since July, the allocation demand for credit bonds from funds, other product categories, and insurance has increased. Credit spreads have mostly narrowed or remained flat due to strong demand, with 1Y varieties showing strong resistance to decline and lower-rated bonds performing better than higher-rated ones [1][10][11]. - Currently, both credit bond coupons and credit spreads are at low levels, and the market trend is more dependent on institutional allocation demand. It is necessary to closely monitor institutional behavior, buying sentiment, and the potential compression space of credit spreads [1][12]. - Overall, the supply - demand pattern in July is favorable for credit bonds, and there is still a small amount of compression space for credit spreads. Specific strategies include focusing on short - to medium - duration bonds with credit rating sinking, and high - grade 10Y bonds have relatively large potential compression space for credit spreads [3][22]. - In the bank capital bond market, although the spread protection is thin, there is still compression space. Long - duration bonds of large banks and 2 - 3 year bonds of small and medium - sized banks are recommended [5]. 3. Summary by Related Catalogs 3.1. Credit Bond Market Overview - From July 1 - 11, funds' net purchase of credit bonds reached 88.5 billion yuan, a year - on - year increase of 39.1 billion yuan. Other product categories and insurance had net purchases of 31.3 billion and 15.2 billion yuan respectively, with year - on - year increases of 7.8 billion and 5 billion yuan [1][11]. - From July 7 - 11, with the convergence of funds and the rotation of negative factors, the bond market fluctuated upwards. Credit bonds, due to strong allocation demand, saw most credit spreads narrow or remain flat [10]. 3.2. Factors Affecting Credit Bond Market 3.2.1. Institutional Behavior - Fund net trading volume of credit bonds is a sensitive indicator related to credit spread trends. Maintaining a daily net purchase of over 500 million yuan helps keep credit spreads low. From July 7 - 10, the rolling 5 - day net purchase was 1 - 1.4 billion yuan, but it dropped to 740 million yuan on the 11th, and was below 500 million yuan on the 10th and 11th [2][12]. 3.2.2. Buying Sentiment - The TKN成交占比 is used to measure buying sentiment. A stable TKN成交占比 above 75% indicates good buying sentiment. From July 7 - 11, as yields rose, the TKN成交占比 declined, with three days below 70%, but the rolling 5 - day average was around 70% [2][16]. 3.2.3. Potential Compression Space of Credit Spreads - By observing the position of credit spreads relative to the mean - 2 times the standard deviation, it is found that currently, each variety still has a small amount of compression space, with 10Y varieties having relatively large potential [3][22]. 3.3. Specific Bond Types Analysis 3.3.1. Urban Investment Bonds - From July 1 - 13, urban investment bonds had a net financing of 28.8 billion yuan. The primary market issuance sentiment was good, with the proportion of full - subscription multiples over 3 times remaining at 61%. The issuance rate of long - term bonds decreased significantly, with the 10 - year average dropping to 2.14% [30][32]. - In the secondary market, short - term bonds were resistant to decline, while the yields of 3 - 10Y bonds increased. The trading activity decreased, and Shenzhen Metro had many high - valuation transactions [35][38]. 3.3.2. Industrial Bonds - From July 1 - 13, industrial bond issuance and net financing increased year - on - year. The issuance sentiment weakened slightly, and the proportion of long - term issuance over 5 years decreased significantly. The buying sentiment in the secondary market weakened, and the trading duration increased [40][42]. 3.3.3. Bank Capital Bonds - From July 7 - 13, several banks issued secondary capital bonds and perpetual bonds. In the secondary market, yields generally rose, spreads showed differentiation, and low - grade, short - duration bonds performed better. Currently, credit spreads are at relatively low levels, but there is still compression space [45][46]. 3.3.4. TLAC Bonds - By comparing the yields of 3Y, 5Y, and 10Y AAA - secondary capital bonds with TLAC bonds, the spreads are analyzed. As of July 11, 2025, the 3Y, 5Y, and 10Y spreads were 3.1bp, 3.8bp, and 1.4bp respectively, indicating that 10 - year TLAC bonds are more cost - effective [53]. 3.3.5. Commercial Financial Bonds - Since 2021, the valuation of 3Y AAA commercial financial bonds has generally followed the trend of interest - rate bonds, with a stable spread center. As of July 11, the credit spread was 14bp, at a relatively low level [57].

1. Report Industry Investment Rating - No information provided regarding the industry investment rating [1] 2. Core Viewpoints of the Report - In the past two weeks, interest - rate bonds fluctuated downward. Institutions continued to explore credit - bond spreads, with long - duration bonds becoming the focus. The 10 - year credit spread has significantly compressed. The trading sentiment of credit bonds is quite extreme. Considering the usual significant decline in wealth - management scale in the last week of June, credit bonds may experience short - term fluctuations. Accounts with unstable liability ends are not advised to chase the rising market but can make arrangements during adjustments. Accounts that have already invested in long - duration credit bonds earlier do not need to rush to take profits as there is still some allocation demand in July. Additionally, there is still room for the spread of long - duration credit bonds to compress [1][3] 3. Summary According to Related Catalogs 3.1 City Investment Bonds - Net financing remains weak. From June 1 - 22, 2025, city investment bonds issued 3781 billion yuan, matured 3767 billion yuan, and only achieved a net financing of 14 billion yuan, a year - on - year decrease of 791 billion yuan.

Joint - stock bank transactions reduced the duration [51] - Regarding TLAC bonds, by subtracting the average yields of 3 + 1, 5 + 1, and 10 + 1 TLAC bonds from the yields to maturity of 3Y, 5Y, and 10Y AAA - secondary capital bonds, the spreads of secondary capital bonds over TLAC bonds were obtained. As of June 20, 2025, the spreads of 3Y, 5Y, and 10Y secondary capital bonds over TLAC bonds were 3.5bp, 7.5bp, and 4.8bp respectively, indicating that the 10 - year TLAC bond was more cost - effective at present [54] - For commercial financial bonds, taking the 3Y AAA commercial financial bond as an example, since 2021, its spread has mostly fluctuated between 10 - 30bp, with a stable spread center at 20bp.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In different bull - bear stages of the bond market, low - grade credit bonds show different performance patterns. In bull markets, low - grade urban investment bonds have the highest narrowing amplitude of valuation yields, and in bear markets, low - grade bonds are relatively "resilient" [1][2]. - In response to the US tariff adjustment policy, from the national to local levels, efforts are being made to support the development of "integrated domestic and foreign trade" market entities and help foreign - trade enterprises expand the domestic market. In the short term, the market may fluctuate due to tariff policies, but in the long term, the impact of tariffs may gradually decrease [3][42]. - This week, the bond market was volatile. Most varieties of financial bonds had a decline in valuation yields compared with last week, and most credit spreads widened. It is not recommended to trade second - tier perpetual bonds too much currently, and attention can be paid to AMC company - related bonds [59][60]. 3. Summary According to Relevant Catalogs 3.1 Different Bull - Bear Stages of Low - Grade Credit Bonds - **Bull Market**: Low - grade urban investment bonds have the highest narrowing amplitude of valuation yields, with the order of AA > AA+ > AAA. For example, from 2022/12/15 to 2023/6/14, the narrowing amplitudes of the yields of 3 - year urban investment bonds of AAA, AA+, and AA were 81BP, 95BP, and 104BP respectively, while the narrowing amplitude of the 3 - year Treasury bond yield was 30BP. This is due to the reduced risk of credit bonds and the high market risk appetite [1][13]. - **Bear Market**: The narrowing amplitude of the yields of AA - rated urban investment bonds is generally lower than that of AAA and AA+ grades (except for a short - term and rapid bear - market stage in 2024/9/23 - 2024/9/29). High - grade credit bonds have better liquidity, and investors have a high demand for coupon assets, so low - grade bonds are relatively "resilient" [2][13]. - **Individual Bonds in Bear Market**: The individual bonds with narrowing valuations in the bear market are mainly concentrated in real estate and some regions with large debt scales. For example, in the bear - market stage from 2025/3/18 to 2025/4/7, many central and state - owned enterprise entities' bond valuations narrowed, which may be because investors thought the bear market would not last long and high - coupon credit bonds were attractive [11]. 3.2 Urban Investment Bonds Weekly Viewpoint 3.2.1 Local Governments Support "Integrated Domestic and Foreign Trade" Market Entities to Cope with Tariff Impacts - The US has continuously adjusted tariff policies, and China has taken a series of counter - measures and internal economic - stabilizing policies. From the national to local levels, efforts are being made to support the development of "integrated domestic and foreign trade" market entities [22][23][26]. - Fujian Province has taken the lead in formulating a specific implementation plan, including establishing a key - enterprise contact mechanism, organizing foreign - trade enterprises to participate in domestic exhibitions, and providing financial and policy support to help enterprises expand the domestic market and international market [27][32]. 3.2.2 Investment Recommendations - **Focus on "Economic Powerhouses"**: Pay attention to provinces with good development momentum and debt management, such as Guangdong, Jiangsu, etc. Their provincial, prefecture - level, and district - county - level platforms are relatively stable, and the duration can be appropriately extended to 5 years [41][42]. - **Regions with Debt - Resolution Policies**: Focus on regions where significant debt - resolution policies or substantial capital inflows have occurred, such as Chongqing, Tianjin, etc. Consider bonds with a duration of 3 - 5 years [42][43]. - **Cities with Strong Industrial Bases**: Pay attention to prefecture - level cities with strong industrial bases and financial support, such as some cities in Guangxi, Hubei, etc. Choose bonds with a duration of 2 - 3 years [46][47]. 3.3 Financial Bonds Weekly Viewpoint - **Overall Performance**: This week, the bond market was volatile. Most varieties of financial bonds had a decline in valuation yields compared with last week, and most credit spreads widened. The widening amplitudes of insurance perpetual bonds and bank second - tier perpetual bonds were larger, while the credit spreads of some bonds such as securities firms' ordinary bonds and short - term financing bonds narrowed [59]. - **Investment Suggestions**: It is not recommended to trade second - tier perpetual bonds too much currently. For short - term commercial financial bonds, partial profit - taking can be considered. Pay attention to 2Y/AAA - and AA+ commercial financial bonds. Also, pay attention to AMC company - related bonds, as the AMC financial bond market is expected to expand [59][60]. 3.4 Primary Market Tracking - The report provides charts on the issuance of credit bonds, financial bonds, the subscription of urban investment bonds and industrial bonds, the issuance costs, the review and registration of credit bonds, and the completion of registration by the credit bond association, but no specific data analysis is given in the summary part [67][68][72]. 3.5 Secondary Market Observation 3.5.1 "Volume" of Secondary Transactions - The report provides a chart showing the trading volume and number of transactions in the secondary market over time, but no specific data analysis is given in the summary part [83][85]. 3.5.2 "Price" of Secondary Transactions No relevant content provided.
