- The People's Bank of China (PBOC) continued its open market operations by conducting a 500 million yuan seven-day reverse repo, fully meeting the needs of primary dealers. The operation rate remains at 1.40%, with the bid amount and the winning bid amount being exactly equal.
- Since there are no reverse repos maturing today, the open market achieved a net injection of 500 million yuan. As of now, the outstanding balance of reverse repos has slightly increased to 55 billion yuan, showing a characteristic of minimal operations.
- Considering the evolution of the liquidity management framework since 2024, the current mechanism of fixed rate and quantity bidding, combined with outright reverse repo tools, demonstrates the monetary authorities' precise control intentions to maintain reasonable and ample liquidity in the banking system, keeping the market funds marginally stable.
Observation of Liquidity Levels in Open Market Operations
Recently, the People's Bank of China's (PBOC) operations in the open market have shown a significant characteristic of minimal operations. The continuous 500 million yuan scale of seven-day reverse repo injections has a minimal impact on the overall liquidity in the interbank market in absolute terms, but the signal of fully meeting the needs of primary dealers is more crucial. This normalized operation, where the bid amount equals the winning bid amount, indicates that the overall interbank funding is in a desirable balance of supply and demand. The structure of the 55 billion yuan outstanding balance shows that there will be a concentrated maturity of about 53 billion yuan in the mid-to-late week, with the rollover pressure on short-term funds being basically controllable. The overnight and seven-day repo rates (DR007) are expected to run smoothly, closely aligned with the policy rate center of 1.40%.
Structural Evolution of the Monetary Policy Toolbox
Reviewing the policy trajectory between 2024 and 2025, the open market operation mechanism has undergone deep structural optimization. Since July 2024, when the seven-day reverse repo was adjusted to a fixed rate and quantity bidding, the transmission path of the policy rate has become more direct. The subsequent introduction of temporary positive and reverse repo operations established an interest rate corridor defense with upper and lower bounds. Notably, the outright reverse repo tool launched in October 2024 further enriched the channels for medium- and long-term liquidity injections. The current daily minimal operations are based on this toolbox of long and short combinations and structural diversity, allowing the central bank to effectively smooth out fluctuations in the funding market with a lower frequency of open market interventions.
Cost Management and Interest Margin of Commercial Banks' Liabilities
Anchored by the short-term policy rate of 1.40%, commercial banks face new constraints in managing the cost of their liabilities. Since May 2025, when the central bank lowered the seven-day reverse repo rate by 10 basis points (bps) from 1.50% to 1.40%, the issuance rates of negotiable certificates of deposit (NCD) and the central interbank offered rate have correspondingly shifted downward. However, due to the transitional structure of credit demand in the real economy, the yield on the asset side is also under pressure, limiting the room for commercial banks to recover their net interest margin (NIM). Against this backdrop, the central bank's precise daily minimal injections prevent the risk of idle arbitrage while ensuring that financial institutions have sufficient liquidity positions to meet daily settlement and credit issuance needs.
Forward Rate Pricing and Macroeconomic Expectations
The current extremely restrained scale of open market operations also reflects the monetary authorities' cautious attitude towards macroeconomic expectations. On trading days without large-scale funding gaps, maintaining a minimal continuation of 500 million yuan aims to convey a stable expectation of maintaining the current liquidity status to the market. If future macroeconomic data show unexpected fluctuations, or if the pace of local government bond issuance suddenly accelerates, creating a draining effect on market funds, the central bank has the space to supplement liquidity at any time by increasing the scale of reverse repos or restarting other medium- and long-term tools. In the short term, market pricing logic will continue to revolve around the existing policy rate curve, with the long-term trend of the yield curve more dependent on the substantive progress of subsequent macroeconomic fundamentals.
