The People's Bank of China (PBOC) announced on July 24 that, to better align with the short-term liquidity needs of the banking system, it will conduct overnight reverse repo operations from July 29 to July 31 and on August 3. The operations will use a fixed interest rate and a quantity-based bidding method. From July 29 to July 31, daily operations will amount to 600 billion yuan, and on August 3, the operation will be 300 billion yuan.

Wang Qing, Chief Macro Analyst at Dongfang Jincheng, stated that the PBOC's announcement of four overnight reverse repo operations aims to leverage the role of overnight reverse repos in regulating ultra-short-term liquidity, better meeting the short-term liquidity needs of financial institutions during month-end and other specific periods.

At the end of June, the PBOC added the overnight reverse repo operation as a new instrument in its open market operations, aiming to further refine the interest rate control mechanism and diversify the maturity of its tools. At that time, operations of 300 billion yuan and 600 billion yuan were conducted on June 29 and June 30, respectively.

It is understood that overnight reverse repo operations can serve a "smoothing" function during special periods, helping to manage liquidity fluctuations. Conducting these operations can improve the efficiency of liquidity management and reduce costs for financial institutions.
