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

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].
