Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The central bank's restart of treasury bond trading is expected to cooperate with government bond supply, align with the current bond market yield curve, and supplement long - term liquidity for the banking system [2][13][19]. - The probability of an interest rate cut within the year has increased compared to the third quarter, while the probability of a reserve requirement ratio cut may decrease after restarting treasury bond trading, but it remains a direct option [3][25][26]. - For the subsequent bond market strategy, the decline space of bond interest rates needs further support. Attention can be paid to whether the central bank's bond - buying scale and maturity exceed expectations [4][27]. 3. Summary According to the Directory 1.1 Why Restart Treasury Bond Trading? - Cooperate with Government Bond Supply and Synergize Fiscal Efforts: In 2025, the government bond issuance from November to December is expected to be around 4 trillion yuan, similar to the same period in 2024. The net financing scale is about 1.70 trillion yuan, significantly lower than 2.98 trillion yuan in 2024 due to the large maturity of treasury bonds in December. Restarting treasury bond trading helps the central bank cooperate with fiscal efforts [2][14]. - The Bond Market Yield Curve Meets the Central Bank's Expectations and Market Risks Decline: Since July 2025, the bond market sentiment has been weak, with the current fund duration at a low level. The 10Y - 1Y and 30Y - 10Y term spreads are both above 35bp, and the yield curve is steep. After restarting treasury bond trading, the short - term interest rate may decline more than the long - term interest rate, and the 30Y - 10Y spread may further compress [2][19]. - Supplement Long - term Liquidity to the Banking System and Stabilize Liability Expectations: As of September 2025, the central bank mainly provided medium - term liquidity through MLF and outright reverse repurchase, accounting for 91.52% of the annual net investment. The 1 - year inter - bank certificate of deposit rate has been rising, indicating that banks lack long - term funds [2][21]. 1.2 Will There Be Other Monetary Policy Coordination within the Year? - Interest Rate Cut: Externally, the pressure of RMB depreciation has decreased, and the narrowing of the Sino - US interest rate spread has reduced the external constraints on China's interest rate cut. Domestically, economic growth has slowed down, and the policy - makers are determined to stabilize growth. The probability of an interest rate cut within the year has increased compared to the third quarter [3][25]. - Reserve Requirement Ratio Cut: Restarting treasury bond trading may reduce the probability of a reserve requirement ratio cut. However, the amount of long - term liquidity provided by treasury bond trading may not meet the banks' demand for long - term funds, so a reserve requirement ratio cut remains a direct option [3][26]. 1.3 How to View the Subsequent Bond Market Strategy? - Since the interest rate has declined significantly, further support is needed to open up the downward space. Attention can be paid to whether the central bank's bond - buying scale and maturity exceed expectations. Currently, the value of chasing and holding active bonds is not strong [4][27]. - 10 - year Treasury Bonds: The main bond has switched to 250016, and the 250016 - 250011 spread may compress to about 3bp in an optimistic scenario [28]. - 10 - year China Development Bank Bonds: Continue to focus on 250215. The uncertainty of 250220 becoming the main bond is high [28]. - 30 - year Treasury Bonds: For short - term trading, focus on 25T6. Consider holding non - active bonds such as 25T5, 24T1, 250002, and 25T3 [28]. - Long - term Interest - rate Bonds: Pay attention to 30 - year old bonds and 50 - year treasury bonds with slightly higher interest rates. For short - term trading with high liquidity requirements, focus on 25T6. For 10 - year interest rates, focus on 250016 and 250215. For medium - term interest - rate bonds, focus on 240006, 250007, and 250018 [29].
