On July 24, the People's Bank of China (PBOC) announced via its official website that, to better match 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.

These operations will use a fixed interest rate and a quantity-based bidding method. Daily operations from July 29 to July 31 will total 600 billion yuan, with a single operation on August 3 amounting to 300 billion yuan.

Ming Ming, Chief Economist at CITIC Securities, commented that this overnight reverse repo operation is similar to the one in June, adopting the approach of a pre-announcement. He also noted that the overnight reverse repo continues the model of fixed rates and quantity-based bidding, without disclosing the winning interest rate. This indicates that the operation is intended as a month-end liquidity support measure.

Industry experts generally believe this pre-announcement is in line with market expectations. Wang Qing, Chief Macro Analyst at东方金诚 (Golden Credit Rating), noted that the PBOC previously announced on July 15 that it was "studying a gradual increase in the frequency of overnight reverse repo operations and communicating with the market." The June operation was also preceded by an announcement. This early communication from the central bank is consistent with expectations.

Regarding the reason for conducting an overnight reverse repo on August 3, Wang Qing analyzed that a large volume of 7-day reverse repos will mature that day. Using an overnight reverse repo to release liquidity on that date can improve liquidity management efficiency, lower costs for financial institutions, and prevent an accumulation of idle liquidity.

Ming Ming held a similar view. "Choosing a 300 billion yuan injection on August 3 is likely to avoid the concentrated maturity of 7-day reverse repos on that day causing too large a shock to the money market and the bond market," he said. Overall, this announcement of the overnight reverse repo operation demonstrates a supportive attitude towards the liquidity market. Although the current funding situation is relatively stable, the unwavering support from overnight reverse repos may also be a forward-looking measure to hedge against the potential impact of future funding pressures on market expectations.
