In a move to better align with the short-term liquidity demands of the banking system, the People's Bank of China has announced it will conduct overnight reverse repurchase operations from September 14 to September 17, utilizing a fixed interest rate and quantity tendering method, with a daily operational cap of no more than 600 billion yuan.

This marks the second consecutive month that the central bank has carried out four consecutive overnight reverse repo operations mid-month, following a similar approach in August. The timing is strategic, as September 15 is the unified deadline for the declaration and payment of the month's primary taxes. The objective is to mitigate the short-term tightening of market liquidity caused by tax-period fund outflows and to guide the short-term money market rate (DR001) to operate smoothly around the policy interest rate.

Notably, while this announcement sets an upper limit for daily overnight reverse repo operations mid-month, the specific operational volume has not been disclosed. The central bank will adjust flexibly based on the actual funding needs of financial institutions, showcasing the operational agility of this approach. Industry insiders predict that the central bank will likely conduct further overnight reverse repo operations at the end of September.

These actions indicate that overnight reverse repo operations are becoming a normalized tool, designed to smooth out liquidity fluctuations at specific points in time, guide DR001 to run steadily around the policy rate, and thereby advance the monetary policy framework's transition from a quantity-based to a price-based system. Wang Qing, Chief Analyst at Oriental Jincheng, believes that overnight reverse repos could gradually replace the 7-day reverse repo as the central bank's core tool for short-term liquidity adjustment. Furthermore, this paves the way for the overnight reverse repo rate to potentially supersede the 7-day reverse repo rate as the primary policy interest rate in the future.

It is important to note that while the central bank is accelerating its push to transition the monetary policy framework toward a price-based model, the fundamental policy stance of maintaining ample liquidity remains unchanged. The future trend for market interest rate operations is to be "more stable," with rate levels primarily following adjustments to the policy rate. The influence of short-term factors such as tax-period fund outflows, government bond issuance payments, policy tool expiries, pre-holiday cash withdrawals, and month-end bank assessments on the liquidity landscape is expected to diminish.
