- On Wednesday, the People's Bank of China (PBOC) conducted a 7-day reverse repurchase operation on the open market, totaling 6 billion yuan, with the operating interest rate maintained at 1.40%. The amount bid and awarded remain the same.
- Considering the 5 billion yuan of reverse repurchases maturing on the same day, the central bank achieved a net injection of 5.5 billion yuan in a single day, slightly increasing the balance of outstanding reverse repurchases in the open market to 12.5 billion yuan, with the overall operation scale still at a relatively low range.
- In the operation announcement, the central bank reiterated that the "full demand of primary dealers was met," indicating that the overall short-term liquidity in the banking system is currently sufficient. The open market operations mainly play a marginal role in smoothing out short-term liquidity fluctuations.
Short-term Liquidity Marginal Adjustment Logic
From the marginal changes in the single-day operation scale, the People's Bank of China slightly increased the previous trading day's amount from 5 billion yuan to 6 billion yuan, demonstrating its tendency for high-frequency and precise management of open market liquidity. Although the net injection of 5.5 billion yuan is minor in the macro liquidity pool, the policy signal it releases serves as a clear anchor. The central bank's continuous emphasis on "fully meeting demand" suggests that the excess reserve ratio in the current banking system remains at a reasonably ample level, with limited demand from primary dealers for short-term positions across days and weeks. This model of small-scale rolling operations primarily aims to prevent frictional liquidity tightening caused by intra-day settlements or short-term tax payments by specific institutions, ensuring that the benchmark money market rate operates smoothly around the policy rate.
Trajectory of Policy Rate System Evolution
The current 1.40% interest rate on the 7-day reverse repurchase operation continues from a 10-basis-point reduction on May 8, 2025. Reviewing the People's Bank of China's recent evolution of its monetary policy toolbox, the 7-day reverse repurchase has effectively become the core anchor of short-term policy rates. Since July 2024, the central bank has adjusted the operation to a fixed-rate, quantity bidding system, complemented by overnight temporary repo and reverse repo to create a more narrow interest rate corridor. Subsequently, in October of the same year, buyout reverse repo tools were introduced to enrich medium and short-term liquidity supply. This series of mechanism optimizations has made current open market operations more transparent. Even with a low absolute operation scale in the billion-yuan range, the 1.40% pricing efficiently transmits to deposit-type financial institutions' pledged repo rates and other market-based benchmarks, effectively managing the market's expectation of the central funding cost.
Liquidity Structure and Reserve Forecasting
Observing the details of the outstanding reverse repo distribution, the current 12.5 billion yuan in funds shows an extremely smooth maturity structure. From April 23 to 29, the daily maturity volume ranges from 5 billion to 6 billion yuan. This evenly distributed maturity structure significantly reduces the impulsive impact on the market from concentrated fund recovery on a single trading day. For financial institutions, this reduces the need for precautionary liquidity, freeing them from keeping excessive redundant reserves in central bank accounts. If there are no substantial fiscal payments or centralized issuance of special bonds in the future, it is expected that this regular model of "micro-operation, meeting demand fully" will continue, strictly limiting the volatility of the short-term capital market.
Pricing of Forward Rates and Bond Market Outlook
With short-term funding costs firmly anchored around 1.40%, the pricing center of the bond market is undergoing structural adjustments. Due to the systematic reduction in short-term interest rate volatility, the front end of the yield curve exhibits strong rigidity. Market participants are increasingly focusing on the medium to long end seeking returns from term spreads. If there are no unexpected rebounds in inflation or credit surges in the macroeconomic fundamentals, the pricing of long-term government bond yields will rely more on expectations of future reserve requirement ratio cuts or the scale of buyout reverse repo operations. The stable operations in the current open market provide a highly certain liquidity base for fixed-income assets, but in an environment where credit spreads have been compressed to historical lows, institutions face the challenge of balancing duration risk control with boosting returns in asset allocation.
