Beginning July 29, the central bank will conduct overnight reverse repo operations for four consecutive working days, specifically on July 29, 30, 31, and August 3, according to the People's Bank of China (PBOC) website.

These operations will use a fixed interest rate and quantity-based bidding system. The daily scale will be 600 billion yuan from July 29 to July 31, followed by 300 billion yuan on August 3, as announced by the PBOC.

Ming Ming, Chief Economist at CITIC Securities, noted that this round of overnight reverse repo operations is similar to the one in June, with the bank opting to "pre-announce" the schedule. Additionally, the PBOC has not disclosed the specific interest rate for these overnight repos, only the operational volume. This indicates that the overnight reverse repo operations are still intended as end-of-month liquidity support rather than a price control tool, and the 7-day reverse repo rate remains the sole policy rate.

Regarding the role of the overnight reverse repo tool, PBOC Deputy Governor Zou Lan explicitly stated at a State Council Information Office press conference on July 15 that the focus is on its ability to adjust ultra-short-term liquidity, not the interest rate. "Some financial institutions may have short-term liquidity needs that only last two to three days. Relying solely on 7-day reverse repo operations could easily lead to liquidity accumulation. Overnight reverse repo operations can more precisely match these temporary funding needs, improving liquidity management efficiency and reducing costs for financial institutions," Zou explained at the time.

Dong Ximiao, Chief Economist at China Merchants Union and Executive Director of the Shanghai Institute of Finance and Development, said that July coincides with bank regulatory assessment deadlines, a major month for tax payments, and an accelerated issuance of government bonds. These converging factors could put significant short-term liquidity pressure on the banking system. The central bank's decision to conduct overnight reverse repo operations at this critical juncture, with a notably larger scale than in June, is a proactive move to hedge against these temporary and seasonal funding needs. This will effectively smooth market fluctuations and ensure stable financial market operations.

"Given the short-term nature and flexible recovery of overnight tools, these operations are more about fine-tuning to address specific time-point pressures, aiming to meet banks' 'bridge' funding needs. This fully reflects the PBOC's intention to maintain dynamic and precise liquidity management, rather than a fundamental shift in monetary policy stance," Dong added.

Wang Qing, Chief Macro Analyst at Dongfang Jincheng, stated that because the central bank had communicated in advance, the doubling of overnight reverse repo operation frequency around the end of July compared to the end of June aligns with market expectations. This also means that the fluctuation of the DR001 (the overnight repo rate) around the end of July will be more effectively controlled, promoting stable short-term rates near the policy rate.

"The decision to conduct an overnight reverse repo operation on August 3 is mainly because it is a Monday, when a large volume of 7-day reverse repo operations are due to mature. Previously, the central bank would mainly use 7-day reverse repo operations to offset such short-term funding needs. Switching to overnight repos this time helps improve liquidity management efficiency, reduce costs for financial institutions, and also helps avoid liquidity accumulation," Wang explained.

Furthermore, the central bank did not disclose the specific interest rate for the overnight reverse repo operations in the recent announcement, only revealing the volume. Dong Ximiao commented that this is a significant step in transitioning the monetary policy framework. The temporary withholding of the rate is mainly due to prudential considerations during the pilot phase and to avoid excessive market interpretation.

"This suggests that overnight reverse repos are primarily serving a short-term liquidity adjustment role, not a price control function. The current main policy rate remains the 7-day reverse repo rate of the central bank," Wang Qing added.
