Group 1: Report Industry Investment Rating - No investment rating information provided Group 2: Core Viewpoints of the Report - The main reason for the recent weakness in the bond market is that the central bank's open - market operations and external expectation management since November have been overall prudent and did not match the market's high expectations. The concerns about policy tone adjustment and “short - term tightening and long - term easing” are more of an emotional interpretation. [1][3] - The bond market is currently facing potential pressures from inflation improvement and the mismatch between supply and demand of ultra - long - term bonds. [8] - Suggestions for responding to the market situation include staying on the sidelines in the near term and paying attention to short - term opportunities and long - term opportunities to steepen the yield curve. [8][9] Group 3: Summary by Relevant Catalogs Reasons for the Decline - **Monetary Policy Factor**: The market's expectations for monetary policy were not met. After the central bank restarted treasury bond trading in late October, the follow - up policy guidance and actual open - market operations were restrained. The third - quarter monetary policy implementation report in mid - November did not echo the over - heated policy expectations. Near the end of the year, discussions about policy setting and the description of “short - term tightening and long - term easing” in the media also affected the bond market. [1][2][3] - **Institutional Behavior Factor**: Concerns about public fund redemption rules and banks selling old bonds are institutional behavior disturbances. The suspension of five - year large - denomination certificates of deposit by large banks and the adjustment of medium - and long - term time deposits by small and medium - sized banks led to a decline in the duration of the liability side and weakened the demand of the allocation disk. The central bank's investigation into banks' selling of old bonds also affected the market. [6] - **Potential Risk Factor**: The bond market is facing inflation pressure from statistical improvement and the strong performance of commodities, as well as the problem of the increasing mismatch between supply and demand of ultra - long - term government bonds. [8] Response Measures - **Stay on the Sidelines**: Pay attention to the tone of the year - end meetings and the central bank's statements to observe the bottom of the recent decline. Wait for the central bank's supportive statements to avoid the potential systemic risk of concentrated redemptions caused by the over - decline of ultra - long - term bonds. [8] - **Focus on Opportunities**: Focus on short - term opportunities and long - term opportunities to steepen the yield curve. Short - and medium - term varieties have higher anti - decline attributes and allocation value. [9]
