Core Viewpoint - The People's Bank of China (PBOC) proposed to cancel the regulation on the freezing of pledged bonds in bond repurchase agreements, which is seen as a significant move to enhance market liquidity and deepen the opening-up of the bond market [1][2]. Group 1: Market Liquidity and Depth - The cancellation of the freezing regulation is expected to release liquidity in the bond market, allowing previously frozen high-liquidity bonds to re-enter the secondary market, thus increasing the available trading volume [2][3]. - Currently, the average daily transaction volume of pledged repos in the interbank market is around 50 to 60 trillion yuan, and releasing just 10% of the frozen bonds could inject an additional 10 trillion yuan into the market, enhancing market activity [3]. Group 2: International Integration - The adjustment aligns China's bond market with international practices, particularly the buyout repo model commonly used overseas, which allows pledged bonds to remain tradable [3][4]. - The move is anticipated to lower operational costs and improve convenience for foreign investors, thereby promoting a higher level of openness in the bond market [3][4]. Group 3: Monetary Policy Efficiency - The removal of the freezing requirement provides greater flexibility for the central bank's monetary policy operations, addressing the issue of "no bonds available for purchase" during bond transactions [4]. - This reform is part of a broader strategy to enhance liquidity management, which includes various measures taken by the central bank since May, aiming to create a comprehensive liquidity support system [4].
