1. Report Industry Investment Rating There is no information provided regarding the industry investment rating in the document. 2. Core View of the Report The report focuses on the history, overseas experiences, and future prospects of China's central bank's treasury bond trading. It analyzes the development of China's central bank's treasury bond trading from 2024 to 2025, draws lessons from the practices of the Federal Reserve and the Bank of Japan, and discusses the possible future evolution of the tool, including operation mechanisms, targets, and implementation rhythms, as well as potential optimization directions for supporting measures [2][48][94]. 3. Summary According to the Table of Contents 3.1. Treasury Bond Trading History Review - Before 2024: The central bank mainly participated in treasury bond trading through repurchase agreements, providing short - term liquidity to the market and smoothing out fluctuations in the capital market. Direct purchases of treasury bonds were rare, mainly for coordinating the issuance of special treasury bonds [12]. - In 2024: The central bank began to include treasury bond trading in open - market operations. In August, it carried out "buying short and selling long" operations, with a net purchase of 1 billion yuan in treasury bonds. The operations were mainly for base money injection and liquidity management, with buying aiming to support fiscal efforts and selling to prevent bond market risks [22][25]. - In the first half of 2025: In January, the central bank announced a temporary suspension of open - market treasury bond purchases, considering the controllable supply pressure of government bonds at the beginning of the year and the availability of alternative tools for liquidity management. The market's speculation about the resumption of operations emerged in June, but it did not materialize, mainly due to the marginal improvement in the supply - demand relationship of government bonds, the central bank's enhanced precision in liquidity regulation, and concerns about bond market risks [38][40][43]. 3.2. Overseas Insights into Central Bank Bond Purchases - Federal Reserve's "Scarce Reserves" Framework: Before 2008, the Federal Reserve used this framework, where treasury bond trading was mainly for liquidity management. Through small - scale open - market treasury bond trading, the Federal Reserve could adjust the reserve level of the banking system, affecting the federal funds rate and other interest rates, forming a transmission chain of "open - market operations - reserve scale - FFR - other interest rates" [48]. - Federal Reserve's Treasury Bond Trading with Quantitative Easing and Twist Operations: From 2008 to 2014, the Federal Reserve implemented large - scale asset purchase programs, aiming to influence the yield curve by changing the structure of purchased assets while maintaining a loose liquidity environment. It carried out operations such as lowering short - term interest rates, buying long - term bonds, and selling short - term bonds, and managing market expectations [68][71]. - Bank of Japan's YCC Practice: In 2016, the Bank of Japan introduced YCC on the basis of negative interest rates. It controlled the short - end through negative interest rates and set a target for the 10 - year treasury bond yield, promising unlimited buying and selling of 10 - year treasury bonds to achieve the target range. This enhanced the central bank's ability to control the yield curve, alleviated concerns about policy sustainability and market liquidity, and strengthened inflation expectations [74][76]. 3.3. Outlook on Central Bank Bond Purchases - Current Situation: Compared with the Federal Reserve and the Bank of Japan, the scale of treasury bonds held by the People's Bank of China is relatively low. Commercial banks are the main holders of treasury bonds in China, accounting for over 60% of the total. The reasons include the short implementation time of treasury bond trading, differences in tool positioning, and the limited liquidity of the treasury bond market [6][78][88]. - Possible Future Deductions: - Operation Mechanism: There is a possibility of making operations more transparent by announcing operation time, quantity, bond maturity, and pricing standards in advance, following the trend of expected management in monetary policy tools [94]. - Operation Target: Treasury bond trading is mainly for liquidity management and may also have the function of regulating the yield curve. Net purchases to inject liquidity are still the general direction, and attention should be paid to the term structure of the treasury bond market and the central bank's holdings [95]. - Implementation Rhythm: The supply pressure of government bonds will decrease in July and peak again in August - September. This could be a good observation window for restarting treasury bond trading operations [97]. - Supporting Measures: Potential optimization directions include increasing the proportion of discount treasury bond issuance, improving the management of treasury bond underwriters, guiding commercial banks to reduce the proportion of bonds held in the AC account, and expanding the participants in the treasury bond derivatives market [98].
