China's Central Bank to Conduct Overnight Reverse Repos Through Sept. 17

The People's Bank of China (PBOC) announced on Sept. 10 that it will conduct overnight reverse repurchase operations from Sept. 14 to Sept. 17. The operations will utilize a fixed-rate, volume tender mechanism, with daily trading volume capped at 600 billion yuan. According to an announcement reported by Xinhua and carried by People's Daily, the measure aims to better align with the banking system's short-term liquidity requirements, reduce funding costs for financial institutions, and smooth temporary liquidity fluctuations at sensitive calendar points.

Overnight reverse repo operations are a key tactical instrument for stabilizing short-term interbank liquidity. By executing these operations via fixed-rate, volume-based bidding at critical settlement windows, the central bank helps anchor short-term market expectations, reduces institutional funding friction, and reinforces the stability of money market benchmark rates.

The People's Bank of China (PBOC) will conduct overnight reverse repurchase agreements from Sept. 14 to Sept. 17, setting a daily operation cap of 600 billion yuan, according to an official announcement reported by state media on Sept. 10. The central bank stated that the scheduled operations are designed to better match the short-term liquidity needs of the banking system. The auctions will be executed through a fixed-rate, volume tender mechanism, providing commercial lenders with direct access to ultra-short-term central bank funding during the designated four-day window. The overnight reverse repo tenor was formally added to the central bank's open market toolkit at the end of June. That structural addition was intended to refine the PBOC's interest rate transmission framework, broaden the available maturities in its open market operations, and enhance precision in daily cash management. State media reports published by Xinhua and People's Daily noted that overnight repo facilities play a distinct role in smoothing liquidity peaks and valleys at specific sensitive junctures. By deploying targeted liquidity injections at set intervals, the central bank aims to improve the operational efficiency of liquidity management across the banking system while lowering financing frictions and funding costs for financial institutions. Market participants typically experience tighter cash conditions around mid-month periods due to tax payments, government bond settlements, and preparations for quarter-end accounting requirements. The PBOC's pre-announced operations signal a commitment to preemptive liquidity fine-tuning, ensuring that overnight interbank borrowing rates remain steady without requiring broader monetary stimulus.
