Overnight Repo Rate Corridor Narrowed to 50 Basis Points: Monetary Policy Enters Precision Phase

At the 2026 Lujiazui Forum, PBOC Governor Pan Gongsheng announced improvements to the short-end interest rate control mechanism with two key measures: narrowing the temporary overnight repo/reverse repo operation rate corridor from 70 basis points to a symmetric 50 basis points, and planning to add overnight reverse repo operations at an appropriate time.

China Financial 40 Forum Research Institute pointed out that a 50-basis-point corridor width is now close to the levels of major global economies. This moderate narrowing helps improve control over short-term money market rates. Meanwhile, the planned overnight reverse repo tool indicates that the benchmark rate will gradually transition from DR007 to DR001. It should be noted that this policy aims to improve interest rate control tools and carries no additional implications for rate adjustments or liquidity injection, and is expected not to change the liquidity stance.

Refinement of Monetary Policy Control

Caitong Securities macro team believes that the previous policy rate lacked adequate guidance for overnight funding. This adjustment signals: first, refined maturity ladder of funding, where intraday small and high-frequency gaps can be precisely matched through overnight tools, large cross-cycle gaps rely on 7-day reverse repo coordination, and quantity tools (MLF, reserve requirement cuts) serve only as medium-to-long-term base money adjustment means, forming a layered control system to better smooth cross-holiday and cross-month-end funding shocks. Second, aligning with global mainstream central bank price-based control, as both the Fed and ECB use overnight rates as core operational targets. China normalization of overnight tools marks the domestic interest rate control framework convergence with mature international systems, creating institutional foundations for gradually phasing out quantity-based indicators and fully anchoring to market rates.

Overall, Tian Lihui, Dean of the Financial Development Research Institute at Nankai University, noted that the core logic of this reform is to push the monetary policy framework toward precision and marketization, with three deeper considerations:

First, strengthening the pricing anchor role of policy rates. By narrowing the overnight repo rate corridor from 70 to 50 basis points, a clearer rate corridor is constructed, compressing the volatility space for short-term market rates and keeping DR001 tightly anchored to policy rates. This directly benchmarks international central bank practices, essentially using institutions to strengthen market expectation management and prevent disorderly rate volatility.

Second, resolving maturity mismatch challenges. The new overnight reverse repo tool fills the gap in PBOC overnight funding control, forming a long-short combination with 7-day operations to precisely match banks short-term liquidity needs.

Third, signaling the transition from quantity-based to price-based framework. The normalization of overnight tools and corridor narrowing both point toward a monetary policy framework that increasingly relies on price signals rather than volume targets.
