The yield of ultra - long credit bonds significantly recovered, the subscription enthusiasm for new ultra - long credit bonds reached a high level, and the long - bond index performed well.

Summary by Directory 3.1 Stock Market Characteristics - The yield of ultra - long credit bonds significantly recovered. From October 27 to 31, 2025, due to factors such as the switch between stock and bond preferences, the central bank's mention of "resuming open - market treasury bond trading operations", and stable capital interest rates, the yield of ultra - long credit bonds dropped significantly. The number of outstanding ultra - long credit bonds with a yield of 2.2% - 2.3% increased to 189 compared with last week [3][14]. 3.2 Primary Issuance Situation - The subscription enthusiasm for new ultra - long credit bonds reached a high level.

Although the ultra - long credit bonds had a good rally this week, and the number of transactions of the most active 7 - 10 - year industrial bonds reached a new high since August (346 transactions), the total number of transactions of general credit bonds over 7 years was still lower than the average weekly reading from June to July. Moreover, compared with ultra - long general credit bonds, the improvement in the allocation preference for ultra - long secondary capital bonds of large banks was relatively greater, and investors paid more attention to the liquidity of bond varieties when choosing long - term bonds [5][33]. - In line with the secondary - market trading performance, the spread of short - and medium - term credit bonds within 3 years returned to the lowest point of the year. To achieve excess returns, ultra - long credit bonds became the target for extending duration.

It is expected that yields will decline in the future, presenting a favorable risk-reward scenario [5] - In Q4, short-term credit bonds with maturities of around two years are expected to perform normally, with yields likely to decrease slightly as overall interest rates decline. However, the decline in yields for longer maturities, such as 10 or 30 years, is expected to be limited [6] - The investment strategy for Q4 should prioritize coupon income, while also allowing for participation in ultra-long duration strategies, but with controlled trading volumes to ensure stability and avoid excessive volatility [6] Additional Important Points - The overall bond purchasing behavior of insurance companies has been influenced by the strong performance of the stock market, which has alleviated some of the asset scarcity issues faced by these institutions [4] - The credit bond market has entered a period of fluctuation, with recent yield movements reflecting a recovery from previous increases, although the overall compression in yield spreads remains modest [2]

Group 1: Report Industry Investment Rating - No information provided Group 2: Core View of the Report - The spread of ultra-long bonds has reached a new high. The yield center of ultra-long credit bonds has continued to rise, the primary issuance has stopped, and the secondary market has shown weak performance. Due to the lack of incremental capital support, the duration strategy still needs to be cautious before the market sentiment significantly recovers [2][3][4] Group 3: Summary According to the Directory 1. Stock Market Characteristics - The yield center of ultra-long credit bonds has continued to rise. During the week of September 29 - September 30, 2025, the bond market sentiment remained weak, and the interest rate center of stock ultra-long credit bonds further increased.

The TKN ratio of varieties with a maturity of over 10 years was at a low level, and the deviation of high - valuation transactions was much higher than that of long - term bonds with a maturity of less than 10 years [4][28] - In terms of the investor structure, funds continued to sell ultra-long credit bonds. Concerns about controlling duration risk and the liquidity flaws of the varieties still affected the allocation behavior of trading desks.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Views of the Report - In Q3, the bond market was mainly affected by anti - involution policies, the stock market, and new fund redemption rules, showing a continuous upward trend. The adjustment in Q3 was characterized by more long - end adjustments, fewer short - end adjustments, fewer low - grade credit adjustments, slightly more high - grade credit adjustments, more adjustments in secondary and perpetual bonds, and fewer adjustments in general credit bonds. In terms of investment returns, credit bonds with a maturity of 2 years or less performed well, while those with a maturity of 3 years or more mostly had negative returns [2]. - Currently, the interest rate may have fully priced in policy and fundamental disturbances. The pattern of weak fundamentals and weak financing demand remains unchanged, and the further upward space of the bond market may be limited [3]. - Historically, the bond market often declines in Q4, and credit spreads usually fluctuate. This year, due to weak bond fund returns and the importance of Q4 performance for the whole - year product performance, market gaming will be more intense, increasing market volatility. For credit bonds in Q4, it is still recommended to focus on coupons, be cautious about duration, and conduct periodic gaming [4][5]. - For different bond varieties, 2 - year short - term bonds are still a solid base and may perform well in the short - term after the holiday. Trading opportunities for secondary and perpetual bonds have emerged again, requiring quick entry and exit in the short - term, and depending on interest rate trends in the long - term. Institutions with unstable liability ends should be cautious about ultra - long - term credit bonds, but their trading volume has increased and shareholding banks have net - bought, indicating a recovery in allocation value, and trading strategies can be tried cautiously [6]. Group 3: Summary by Related Catalogs 1.1 How was the performance in Q3? - The bond market was affected by anti - involution policies, the stock market, and new fund redemption rules, showing a continuous upward trend. In July, anti - involution policies were further implemented, and the bond market rose significantly; in August, the stock market rose strongly, suppressing bond market sentiment; in September, new fund redemption rules were introduced, and various news such as good industrial enterprise profits in August, progress in Sino - US negotiations, and the cancellation of fund tax exemption impacted the market [13]. - The Q3 adjustment showed characteristics of more long - end adjustments, fewer short - end adjustments, fewer low - grade credit adjustments, slightly more high - grade credit adjustments, more adjustments in secondary and perpetual bonds, and fewer adjustments in general credit bonds [15]. - In terms of investment returns, 2 - year and shorter - term credit bonds performed well with positive returns, while bonds with a maturity of 3 years or more had poor investment returns, and the longer the maturity, the worse the performance. For example, the investment return of the 30 - year treasury bond in Q3 was only - 7.818% [19]. 1.2 Will the downward trend continue? - In August, the year - on - year growth rate of industrial enterprise profits was 20.4%, mainly driven by industries such as power, heat production and supply, and metal smelting and processing. However, the sustainability of the profit recovery is limited due to factors such as the continuous decline in futures prices and weak social demand. The growth rates of both social financing and core social financing are declining, and the further upward space of the social financing growth rate is limited [21]. - Currently, the market interest rate has fully reflected the marginal changes in fundamentals and inflation. Considering the term spread of interest - rate bonds and the comparison between long - term interest rates and certificates of deposit, the further upward space of interest rates is limited, and there may be a downward trend at the end of the year [22][31]. 1.3 How to view credit spreads? - If interest rates do not rise further, credit spreads will likely fluctuate. Historically, credit spreads in Q4 mostly fluctuate. If the capital interest rate can remain stable, the pricing logic system of capital - certificates of deposit - credit will be more stable. Currently, the comparison between medium - term notes and certificates of deposit has risen significantly but is expected to fall back, and the term spread of credit bonds has reached a relatively high level in the past two years and is expected to have limited further upward space [35][40]. 1.4 How to understand the seasonality of the bond market and institutional psychology? - The bond market tends to decline in Q4. In the past 9 years from 2016 to now, interest - rate bonds rose only in 2016, 2017, and 2022, and declined in other years. Credit bonds generally perform worse than interest - rate bonds of the same maturity in Q4. This year, due to the poor performance of medium - and long - term bond funds, market gaming in Q4 will be more intense, increasing market volatility. Products with good performance may focus on controlling drawdowns, while those under performance pressure may more aggressively play the long - duration strategy [43][47][49]. 1.5 How to construct a portfolio? - Medium - and short - term credit bonds should still focus on defense. Holding credit bonds with a maturity of less than 2 years until the end of Q4 can withstand an upward range of more than 30bp, and appropriate credit risk exposure can also lead to good coupon performance [52]. - Ultra - long - term credit bonds: Their credit spreads are close to the high point in the past two years, and their trading volume has increased, and shareholding banks have net - bought, indicating that they have allocation value. Currently, the comparison between secondary and perpetual bonds and general credit bonds has risen to a high level, presenting trading opportunities [56][58][59]. 2.1 It is recommended to focus on medium - and long - term secondary and perpetual bonds - At the end of September, the comparison between 5 - year secondary and perpetual bonds and medium - term notes rose rapidly. The comparison advantages of 5 - year secondary capital bonds of all grades over 5 - year medium - term notes increased significantly, and the comparisons of AAA, AA +, and AA grades are currently 9.96bp, 9.08bp, and 4.08bp respectively, still at a high level this year. The comparisons of 1 - year secondary bonds of all grades with medium - term notes are all negative [63]. - The comparison between short - end urban investment bonds and medium - term notes has declined significantly, breaking through the low point of the year, and the cost - performance of medium - and low - grade bonds is relatively low, so entry still needs to wait. The comparison between long - end weak - quality urban investment bonds and medium - term notes has increased [65]. 2.2 Focus on high - coupon assets with a maturity of about 2 years - Currently, the proportion of urban investment bonds with a valuation of over 2.3% is 38.0%, that of non - financial industrial bonds is 24.5%, and that of secondary and perpetual bonds is 33.3%. Bonds with a maturity of about 2 years and a valuation of over 2.3% have good value and are worth attention [67]. - For urban investment bonds, long - end bonds can combine coupon and band operations, and short - duration high - coupon varieties can still be participated in. It is recommended to focus on bonds with a maturity of about 2 years issued by companies such as Xi'an High - tech, Henan Aviation Port, and Zhuhai Huafa [68]. - For industrial bonds, among real - estate enterprises, it is recommended to focus on bonds of important local state - owned real - estate enterprises with a maturity of about 2 years, such as Shoukai, Jianfa, and CCCC Real Estate. Among non - real - estate industrial entities, focus on bonds with a maturity of less than 2 years issued by enterprises such as Jizhong Energy and AVIC Industry Finance, and bonds with a maturity of about 2 years issued by enterprises such as HBIS and Yunnan Investment [72]. 3.1 How was the market performance? - On September 29 - 30, credit bonds generally recovered, and spreads generally widened. Credit bond yields declined slightly, with short - end secondary and perpetual bonds performing more significantly, while 10Y secondary and perpetual bonds continued to rise. Credit spreads widened overall, and the spreads of secondary and perpetual bonds showed a differentiated trend, with short - end spreads declining and long - end spreads widening [74].

Group 1 - The report highlights a recovery in the over-sold perpetual bonds (二永) after a significant reduction in holdings the previous week, with a slight easing of selling pressure observed [1][9][15] - The overall sentiment in the bond market is mixed, with short-term credit showing resilience, while long-term credit continues to decline, leading to a steepening of the yield curve [1][8][15] - The report notes that funds are in a process of reducing duration, particularly cautious towards long and ultra-long credit, with a cumulative reduction of over 50% in long credit since late July [1][15] Group 2 - Historical data indicates that in the last week before holidays, the scale of wealth management products typically declines significantly, with a drop of over 800 billion yuan noted since 2022, and over 900 billion yuan in 2024 due to equity market influences [2][23][32] - The report states that the credit spread has fluctuated around the holiday periods, with a tendency to compress in the first week after the holiday [2][32] Group 3 - The report recommends a focus on coupon strategies for credit bonds, suggesting that avoiding significant exposure to credit varieties is prudent due to potential market disturbances [3][38] - Specific recommendations include selecting short-term coupon assets, particularly those with yields above 2%, and considering trading opportunities in 3-4 year high-grade perpetual bonds, which currently yield 1-3 basis points higher than benchmark bonds [3][38] - Caution is advised for ultra-long credit, with suggestions to reduce holdings as the trading profit potential appears limited [3][38]

Report Industry Investment Rating No relevant information provided. Core Viewpoints The report analyzes the market conditions of ultra - long credit bonds from multiple aspects, including the adjustment of yields in the stock market, the increase in new bond supply in the primary market, and the decline in index prices and weak trading sentiment in the secondary market. It also points out that institutions should pay attention to market sentiment changes around the listing of the second batch of Sci - tech Innovation Bond ETFs when participating in the ultra - long credit bond market [2][3][4]. Summary by Directory 1. Stock Market Characteristics - Ultra - long credit bond yields continued to adjust. Due to the impact of new public fund regulations on the bond market this week, assets with insufficient safety margins, such as medium - and long - duration secondary bonds and general credit bonds over 7 years, faced significant adjustment pressure. The number of stock ultra - long credit bonds with a yield of 2.4% - 2.5% increased to 353 compared with last week [2][12]. 2. Primary Issuance Situation - The supply of new ultra - long credit bonds increased significantly. The total issuance scale of new ultra - long credit bonds this week was 40.19 billion, reaching the highest point this year, mainly affected by the large - scale issuance of ultra - long individual bonds by Everbright Group. Due to the overall pressure on the bond market, the market's sentiment towards primary - market allocation was cautious, and the coupon rates of new ultra - long credit bonds generally continued to rise. However, investors had a certain degree of recognition for the high - quality ultra - long new bonds of Everbright Group, as shown by the rebound in the subscription enthusiasm for new ultra - long industrial bonds in the latest week [3][21]. 3. Secondary Trading Performance - The price of the ultra - long credit bond index continued to fall. This week, the price index trends of various bonds continued to diverge. Medium - and short - duration credit bonds were more resilient, while long - duration varieties faced price pressure. The index of AA + credit bonds over 10 years decreased by 1.02% month - on - month [29]. - The trading sentiment of ultra - long credit bonds remained sluggish. This week, due to redemption pressure, the selling pressure of trading desks on ultra - long credit bonds intensified. Although the number of transactions of credit bonds over 7 years increased slightly, the average transaction yield increased significantly compared with last week. In terms of spreads, the spread between industrial bonds over 10 years and 20 - 30 - year treasury bonds widened to over 35bp [32]. - Correspondingly, the proportion of TKN of ultra - long credit bonds over 10 years was less than 50% this week, and the average discount of 20 - 30 - year urban investment individual bonds reached over 5BP, highlighting the heavy selling pressure from sellers [37]. - In terms of investor structure, due to concerns about the stability of the liability side, funds have been reducing their holdings of ultra - long credit bonds for five consecutive weeks. The net selling scale of ultra - long credit bond varieties in the latest week exceeded 3 billion, intensifying the market selling pressure. Institutions such as insurance and wealth management participated slightly during the adjustment, reflecting the allocation demand for high - coupon long - term bonds [43]. - From a more microscopic perspective, the spreads between active ultra - long credit bonds of each maturity and treasury bonds of similar maturities continued to widen this week. The spreads of varieties around 10 years have risen to over the 60th percentile since 2024. In the future, there are still liquidity flaws in ultra - long credit bonds. If institutions intend to participate, they need to avoid excessive selling and pay attention to the market sentiment changes around the listing of the second batch of Sci - tech Innovation Bond ETFs [46].
