On August 25, the People's Bank of China (PBOC) officially executed a 500 billion yuan Medium-Term Lending Facility (MLF) operation. A day prior, the central bank had released successive open market operation announcements, not only detailing the 500 billion yuan MLF but also pre-announcing overnight reverse repo operations capped at 600 billion yuan per day. This dual-pronged approach to short-term and medium-term liquidity management is designed to maintain reasonably ample liquidity in the banking system and ensure stable money market interest rates.
According to the PBOC's official announcement, to preserve ample liquidity in the banking system, a 500 billion yuan one-year MLF operation was conducted on August 25 using fixed quantity, interest rate bidding, and multiple-price auction methods. With 600 billion yuan in MLF maturing that month, this resulted in a net withdrawal of 100 billion yuan, ending a streak of three consecutive months of increased rollover volumes. On the same day, the PBOC announced that, to better align with the banking system's short-term liquidity needs, overnight reverse repo operations would be conducted from August 27 to September 1, using fixed interest rates and quantity tenders, with daily operations capped at 600 billion yuan.
Additionally, on August 25, the PBOC conducted 386 billion yuan in 7-day reverse repo operations using fixed interest rates and quantity tenders, fully meeting the demand from primary dealers. Combined with the 600 billion yuan MLF maturity and the 500 billion yuan MLF injection, the open market operations achieved a net injection of 286 billion yuan. Shen Xiayi, deputy dean of the Research Institute at Lianchuang Securities, told reporters that the central bank's "combination punch" of scaled-down MLF rollover, increased overnight reverse repos, and expanded 7-day reverse repos sends two clear signals.
First, while overall liquidity remains ample, short-term structural pressures persist, with operations targeting fine-tuned adjustments rather than broad-based easing. With 600 billion yuan in MLF maturing in August, the 500 billion yuan rollover implies a net reduction of 100 billion yuan, marking the first contraction in nearly four months. However, during the same period, outright reverse repos with 3-month and 6-month tenors injected a combined net 200 billion yuan, meaning medium-term liquidity still saw a net addition of 100 billion yuan overall. Second, the short-term funding market faces dual pressures from MLF maturities and the peak season for government bond settlements, with net government bond payments this week reaching nearly 800 billion yuan, a weekly high for 2025. The central bank has chosen overnight reverse repos to precisely offset the month-end funding gap.
Shen further explained that the 600 billion yuan daily cap on overnight reverse repo operations essentially functions as a "liquidity safety net with an upper limit." It sets a safety margin for month-end funding conditions while using quantitative constraints to prevent excessive leverage by institutions, thereby anchoring short-term rates like DR001 near the policy rate and compressing tail-end volatility in month-end funding costs. For the money market, this effectively constructs an implicit lower bound for the short-end interest rate corridor, reducing the risk of rate spikes during quarter-end and month-end periods.
On August 24, funding rates showed mixed movements. The Shanghai Interbank Offered Rate (Shibor) for overnight funds fell 1.5 basis points to 1.419%, while the 7-day Shibor rose 0.64 basis points to 1.432%. By market close that day, the weighted average rate for DR007 had climbed to 1.4339%. By August 25, short-end rates trended upward, with overnight Shibor rising 1.6 basis points to 1.4350%, the 7-day Shibor gaining 2.15 basis points to 1.4535%, and the DR007 weighted average rate at 1.4531%.
Looking ahead to future monetary policy direction, Du Tongtong, a researcher at the Lianchuang Securities Research Institute, believes the overall stance will continue to be "moderately accommodative," but with greater emphasis on precision and structural measures. Regarding reserve requirement ratio (RRR) cuts and interest rate reductions, market expectations are currently divided. Some institutions argue that the likelihood of further easing in the second half of the year is low, with monetary policy focusing more on complementing fiscal efforts. Others anticipate that the third quarter represents a critical window, with RRR cuts potentially preceding rate cuts. Du noted that based on the tone of the central bank's second-quarter monetary policy implementation report, "comprehensively utilizing and timely adjusting monetary policy tools" is the overarching theme. The probability of a broad-based rate cut in the near term is relatively low, but targeted RRR cuts cannot be ruled out, depending on liquidity conditions and discretionary decision-making.
Additionally, structural tools are expected to continue playing a significant role: re-lending facilities for technological innovation and technological transformation, green and low-carbon transition instruments, and support tools for inclusive small and micro loans are likely to be extended or expanded, focusing on serving the cultivation of new productive forces and financing for weak links. "Furthermore, it cannot be ruled out that the central bank will further refine the interest rate corridor mechanism, diversify the tenors of repo operations, and create targeted support tools for key areas such as real estate and consumption," Du said.
