Recent weeks have seen a flurry of activity in the money market, with several events pointing toward a significant evolution in how monetary policy is implemented. The People's Bank of China (PBOC) has signaled a clear acceleration in its transition from a quantity-based to a price-based monetary policy framework, a move highlighted by a dedicated column in its latest quarterly report. At the heart of this change is the central bank's focus on ensuring stability in short-end interest rates and smoothing the transmission chain of monetary policy.
In its recently published monetary policy implementation report for the second quarter, the PBOC devoted a special section to "perfecting the short-end interest rate control mechanism." This follows a series of market developments, including the first loan priced against the DR benchmark rate, a pause in 7-day reverse repo operations, and the injection of over 900 billion yuan through overnight reverse repos. These seemingly separate events all point to the same direction: the central bank is moving toward a more market-oriented approach to managing liquidity and interest rates, with a specific emphasis on stabilizing the overnight rate, a shift from its previous focus on the 7-day rate.
The report's column explains that while most global central banks target short-end money market rates, the PBOC is now looking to refine its own toolkit. It explicitly designates the 7-day reverse repo rate as the primary policy rate while downplaying the policy attributes of other tools, and it notes a gradual shift in its operational target from DR007 toward DR001. This reflects a broader effort to enhance the precision and effectiveness of liquidity management and short-end rate guidance, ensuring that money market rates run smoothly around the policy rate.
According to Wang Qing, chief macro analyst at Golden Credit Rating, the column signals the central bank's intention to speed up its transition to a price-based framework. The logic is that only with a truly stable and predictable short-end rate can an effective interest rate benchmark be formed, which in turn can smooth the transmission from the money market to the credit and bond markets. This shift also means the central bank's attention has moved from the medium-term stability of the 7-day policy rate to the daily fine management of the overnight rate.
The new strategy could eventually lead to a change in the primary policy rate anchor. The PBOC has announced that it will gradually increase the frequency of overnight reverse repo operations based on the needs of primary dealers, and recent data shows that while 7-day reverse repo operations have seen zero volume for five consecutive trading days, overnight operations have been conducted on multiple days with substantial volume. Analysts suggest this indicates the overnight reverse repo is becoming a normalized tool and may eventually replace the 7-day reverse repo as the core instrument for short-term liquidity adjustment, potentially paving the way for the overnight reverse repo rate to become the main policy rate.
This potential "anchor change" is seen as necessary in the long run. The 7-day reverse repo has been the mainstay of open market operations for years, balancing operational precision with the pressure of maturity rollovers. However, with overnight transactions now accounting for over 90% of money market repo trading, and with institutions often needing liquidity for just two or three days around month-end or tax periods, the overnight operation offers greater efficiency and lower costs. Compared to the practices of the Federal Reserve and the European Central Bank, the overnight rate is more real-time and representative of market conditions, making it a more suitable international-standard policy anchor.
However, the transition is not yet complete and requires a steady, gradual approach. The timing of the official implementation could be gauged by two factors: whether the central bank begins to publish the winning interest rate for overnight reverse repos on a regular basis, and whether the DR001 average is officially incorporated as a core reference for loan pricing. If both are confirmed simultaneously, the anchor change process may begin in earnest.
Beyond this, the PBOC is also working on constructing a complete transmission chain as part of its broader interest rate liberalization reform. The introduction of DR benchmark rate loans, alongside the existing LPR mechanism, aims to create a diversified benchmark rate pricing system. This reform addresses two key issues: the high volatility of short-end market rates and the slow transmission from money market rates to loan rates. The ultimate goal is to allow the central bank to influence the entire financial system's funding costs by adjusting one core policy rate, thereby achieving more precise policy effects with smaller liquidity injections, all in service of the macro-control objectives of stabilizing growth, prices, and preventing risks.
To achieve this final goal, however, deeper institutional constraints must be addressed. This includes promoting market-oriented reforms in financial institutions and state-owned enterprises. Reforming state-owned enterprises is essential to solve the problem of their low sensitivity to loan rates and financing costs. In the meantime, quantity-based controls are expected to continue playing a role for some time to come.
