- After the May Day holiday, the People's Bank of China (PBOC) maintained minimal operations on the compensatory workday, conducting a 5 billion yuan 7-day reverse repo on Saturday, with the bid rate unchanged at 1.40%, achieving a net injection of the same amount for the day.
- This week, the open market operations resulted in a net withdrawal of 365.1 billion yuan, indicating that liquidity in the banking system has returned to a highly abundant state after the month-end, with the central bank's focus shifting to preventing excessive accumulation of funds.
- The outstanding balance of reverse repos in the open market slightly rose to 54 billion yuan, with the policy transmission efficiency of interest rate tools being further strengthened through the fixed rate and quantity bidding mechanism.
Market Liquidity Returns to Normalcy
After the May Day holiday and month-end fluctuations, the interbank market in China is showing a highly relaxed liquidity stance. The central bank only injected 5 billion yuan today, reflecting not only the absence of maturing funds but also signaling the regulators' satisfaction with the current total amount of funds, indicating no need for additional liquidity support. From the operational details, the PBOC continued its previously adjusted mechanism, with a fixed rate of 1.40% and full demand satisfaction, reflecting a shift in open market operations towards anchoring to the benchmark interest rate. This week's net withdrawal of 365.1 billion yuan effectively offset the redundant positions injected earlier to cope with month-end pressures, ensuring market rates operate smoothly around the policy rate.
Operation Frequency and Toolbox Evolution
Since the second half of 2024, the central bank's monetary policy framework has undergone significant optimization. Today's operation once again confirmed the status of the 7-day reverse repo as the main policy rate. Reviewing historical standards, from the introduction of temporary reverse repos in July 2024, to the launch of outright reverse repos in October, and the reduction of the 7-day rate to 1.40% in May 2025, the PBOC's toolbox has become increasingly rich and precise. Currently, the 14-day reverse repos and temporary operations in the open market are linked to the 7-day benchmark, forming a clear system of basis points adjustments. This highly transparent interest rate corridor system reduces the expected costs for financial institutions, significantly decreasing the volatility of short-term funding costs.
Outstanding Balance Distribution and Maturity Pressure
According to the latest data, the total outstanding balance of reverse repos is 54 billion yuan, mainly concentrated at the beginning of next week. Specifically, 26 billion yuan and 27 billion yuan will mature on May 13 and 14, respectively, while the latter half of the week will see a drop to an extremely low level of 5 billion yuan per day. Given the current small scale of outstanding amounts, even the concentrated maturities at the beginning of next week will have a relatively limited impact on the consumption of excess reserves in the interbank market. Analysts generally expect that unless irrational fluctuations occur, the central bank will continue to maintain minimal or small-scale rolling operations to maintain a neutral balance of market expectations, avoiding a rapid increase in bond market leverage due to overly loose liquidity.
Policy Outlook and Potential Variables
Looking ahead to mid-to-late May, the market's focus is shifting from short-term reverse repos to the renewal of the Medium-term Lending Facility (MLF) and the pace of local bond issuance. If government bond issuance in May significantly increases, causing temporary pressure on the banking system's excess reserve ratio, the central bank may increase the scale of reverse repo injections or use outright tools for hedging. Additionally, considering the complexity of the global monetary environment since 2025, the moderate rebound in domestic inflation data, and the relative stability of the exchange rate provide a favorable space for the central bank to maintain the policy rate at 1.40%. If future market rates continue to deviate from the policy anchor, the central bank may use the temporary operation window from 16:00 to 16:20 for reverse adjustments to ensure liquidity is precisely directed towards the real economy.
