机构称超长债期限利差难以持续大幅扩张 配置价值逐步显现
Xin Hua Cai Jing· 2025-09-23 14:49
Core Viewpoint - The recent adjustment in the bond market has led to an expansion of the yield spread between ultra-long-term government bonds and 10-year government bonds, reaching a year-to-date high, but this trend is expected to stabilize with limited further expansion potential [1][3]. Group 1: Market Performance - Since mid-September, the yield spread between 30-year and 10-year government bonds has consistently remained above 30 basis points, peaking at 33.31 basis points on September 11 [1]. - The overall bond market has been adjusting, with ultra-long bonds showing relatively weaker performance, as the yield on 30-year government bonds did not experience significant downward movement despite the recovery in 10-year government bonds, which surpassed 1.8% [1][3]. Group 2: Factors Influencing Yield Spread - The widening yield spread for ultra-long bonds is attributed to multiple factors, including market risk appetite, supply, and funding conditions. The rise in stock market sentiment has weakened bond market sentiment, leading to a corresponding adjustment in bond yields [3]. - Since May, there has been a peak in the issuance of ultra-long special government bonds, which has contributed to the widening of the yield spread due to increased supply expectations [3]. Group 3: Future Outlook - Analysts from Zhongyou Securities predict that the yield spread for ultra-long bonds is unlikely to expand significantly, suggesting that it will not return to historical levels above 40 basis points prior to 2023 [5]. - The liquidity of ultra-long bonds is deemed crucial, and as long as liquidity remains stable, the yield spread is unlikely to revert to levels seen before 2024. Current liquidity conditions show no significant decline, maintaining a high turnover rate [5]. - The current high yield spread of 30 basis points between 30-year and 10-year government bonds indicates limited further adjustment space for ultra-long bonds, suggesting potential value for allocation and trading [5].

证券研究报告 | 固定收益定期 gszqdatemark 2025 09 22 年 月 日 固定收益定期 超长债,风险还是机会? 近期随着债市的持续调整,超长债下跌明显,期限利差显著拉大。近期 30-10 年 国债期限利差的显著拉大,从 7 月初 21bps 左右上升至目前 30bps 以上,上升至 2024 年以来的最高位。随着债市压力持续,以及市场对资本利得希望的降低,对 超长债出现持续看弱的声音。那么超长债是否不再具备投资价值,当前位置,是风 险还是机会呢? 当前超长债期限利差走阔背后,有风险偏好、供给和资金等多方面原因。股市上 升提升风险偏好,是超长债利差走阔的原因之一。今年 7 月以来,市场风险偏好 抬升,A 股明显走强。股债跷跷板效应下,市场对债券的投资热情下滑,如债券基 金份额出现回落。随着债券市场情绪走弱,债券收益率也随之明显调整。风险偏好 提升导致 30 年-10 年国债利差走阔。供给端冲击可能是另一个原因。从此前经验 来看,供给冲击预期之下,超长债利差往往有所拉大。今年 5 月以来超长期特别 国债开始加速发行,除 6 月净融资额为 1920 亿元外,其余月份均超过 2000 亿元, 显著超 ...

Report Summary 1. Report Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - Short - term bond market sentiment remains under pressure. It is crucial to verify that the rebound high of long - term interest rates is gradually decreasing. If 1.8% is confirmed as the relatively high level of the 10 - year Treasury bond, the bond - bull logic can be maintained. In the medium term, the recovery of risk appetite is mainly reflected in the term spread premium, which may reach 50 - 60BP in extreme cases. In September 2025, the bond market is more likely to experience a weak recovery rather than a seasonal adjustment [2][9]. - The term spread of ultra - long bonds is difficult to return to extremely low levels but is unlikely to expand significantly, and there is no need to refer to the historical range above 40BP before 2023 [3][14]. - The short - term recovery of the bond market may be driven by monetary easing. If a 10BP policy rate cut is implemented, the central level of funds and short - term varieties will decline by more than 10BP. The performance of long - term bonds is more affected by expected pricing, and the resistance at 1.7% - 1.75% of the 10 - year Treasury bond may be significant [4][19]. 3. Summary by Related Content 3.1 Bond Market Situation in September 2025 - The bond market has not significantly recovered, long - term bond interest rates are oscillating, and the term spread is expanding. After the public offering fee new rule and the central bank bond - buying expectation emerged, the long - term interest rate rebounded after breaking through 1.8% and then maintained an oscillating state. The term spread has not stopped recovering due to the unclear impact of the public offering fee new rule on the liability side [3][9]. 3.2 Analysis of Ultra - Long Bond Term Spread - **Difficulty in Returning to Low Levels and Limited Expansion**: The ultra - long bond term spread is closely related to risk appetite, reflecting the marginal change in the household debt cycle. As the household sector's leverage ratio has entered the stable - leverage stage and the real - estate cycle has not ended, the improvement of household risk appetite is limited, so the term spread is difficult to return to the high - level range before extreme compression [14][15]. - **Uncertainty from Supply and Demand**: Although the supply of ultra - long - term interest - rate bonds has increased (as of mid - September, the stock of ultra - long - term interest - rate bonds over 10 years has reached 27.3 trillion yuan, and the proportion has increased from 7% in Q1 2019 to 23%), it is difficult to determine the term spread trend from the supply side alone because the demand elasticity has a greater and unpredictable impact. Historically, the term spread has compressed even when the supply increased. In the short term, the completion of ultra - long bond issuance in Q4 may reduce the spread expansion pressure [17]. 3.3 Short - Term Bond Market Recovery Drivers - The short - term recovery of the bond market may be driven by monetary easing. A 10BP policy rate cut will lead to a central decline of more than 10BP in the funds and short - term varieties. The 10 - year Treasury bond has heavy chips around 1.7% - 1.75%, and the resistance to unwinding may be obvious [4][19].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Last week, the situation of the trade war was uncertain, causing the bond market to fluctuate. With a loose funding environment and the overnight interest rate dropping back to 1.4%, ultra-long bonds were slightly pressured, showing a V-shaped trend throughout the week. The trading activity of ultra-long bonds increased slightly, and both the term spread and the variety spread widened [1][11]. - For the 30-year treasury bond, as of May 30, the spread between the 30-year and 10-year treasury bonds was 23BP, at a historically low level. Considering domestic economic data, the economy in April still showed resilience. The estimated year-on-year GDP growth rate in April was about 4.1%, a 0.8% decline from March but still higher than the annual economic growth target. In terms of inflation, the CPI in April was -0.1% and the PPI was -2.7%, indicating obvious deflation risks. With the recent easing of Sino-US trade frictions and the dissipation of investors' pessimistic expectations, the short-term focus will shift to the domestic economic data of the second quarter. It is expected that as the policy support effect weakens, the bond yield is more likely to decline. However, the current term spread of the 30-year treasury bond is still low, providing limited protection [2][12]. - For the 20-year CDB bond, as of May 30, the spread between the 20-year CDB bond and the 20-year treasury bond was 2BP, at a historically extremely low level. The domestic economic situation in April was similar to that of the 30-year treasury bond. It is also expected that the bond yield will decline as the policy support effect weakens. However, the current variety spread of the 20-year CDB bond is still low, providing limited protection [3][13]. 3. Summary by Relevant Catalogs 3.1 Weekly Review - **Ultra-long Bond Review**: Last week, due to the uncertain trade war situation and a loose funding environment with the overnight interest rate at 1.4%, ultra-long bonds were slightly pressured, showing a V-shaped trend.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core View of the Report - The supply of ultra-long bonds in 2025 is estimated. The supply pressure is expected to be high in February, August - September, with a monthly issuance scale possibly exceeding 70 billion yuan. The supply of ultra-long bonds will affect the term spread of ultra-long bonds and the spread between ultra-long local bonds and treasury bonds. The term spread of ultra-long bonds may widen slightly, and the spread between ultra-long local bonds and treasury bonds is expected to narrow [7][20][21] Group 3: Summary by Relevant Catalogs 1. Ultra-long Bond Supply Estimation - Ultra-long general treasury bonds have a small supply and are expected to be issued concentratedly from January - April and November - December. The assumed issuance scale of subsequent single 30-year and 50-year general treasury bonds is 30 billion yuan and 20 billion yuan respectively [10] - Ultra-long special treasury bonds are expected to have high supply pressure in May, August - September. The total annual issuance is 1.3 trillion yuan. The assumed issuance scale of subsequent single 20-year, 30-year, and 50-year special treasury bonds is 5 - 6 billion yuan, 6 - 7 billion yuan, and 4 - 4.5 billion yuan respectively [12] - The proportion of ultra-long bonds in local special bonds has increased, and the issuance is expected to surge from August - September. The assumed proportion of ultra-long bonds remains at 69.2%. The monthly issuance scale may exceed 50 billion yuan [15] - Ultra-long local refinancing bonds are expected to be issued by June, with controllable supply pressure. The monthly issuance scale from May - June is estimated to be 14.98 billion yuan [17] 2. Impact on the Bond Market - As the issuance of ultra-long bonds increases, the term spread of ultra-long bonds may widen slightly. The impact of ultra-long bond supply on the term spread is asymmetric. When issuance is high, the term spread is supported but rarely widens significantly; when issuance is low, the term spread is significantly compressed [20] - The spread between ultra-long local bonds and treasury bonds is expected to narrow. When the supply of ultra-long treasury bonds is relatively large, the spread between ultra-long local bonds and treasury bonds tends to narrow, and vice versa [21]
