Overnight reverse repos launched in mid-month for the first time. The People’s Bank of China (PBOC) announced on August 12 that to better match short-term liquidity demand in the banking system, it will conduct overnight reverse repo operations on August 14, and August 17–19 via fixed-rate quantity tenders, with a daily operation volume capped at RMB 600 billion.

Marking the first mid-month deployment since its debut on June 29, the overnight reverse repo tool had previously been deployed mainly at month-end and month-start periods. Pang Ming, member of the China Chief Economist Forum, said the move reflects flexibility and forward-looking arrangements in liquidity management. Timing-wise, the mid-month tax payment peak, together with seasonal disturbances such as government bond issuance settlements, often triggers localized tightening in short-term funding conditions and interest rate volatility, he explained.

“Overnight reverse repos help anchor market interest rates within a reasonable range,” Pang Ming noted. Dynamic peak-shaving and valley-filling through these operations can offset short-term liquidity supply-demand gaps via frequent and targeted fine-tuning.

Ming Ming, Chief Economist at CITIC Securities, pointed out that August 15 falls on a Saturday, making August 17 both the reserve requirement payment date and the deadline for tax filings. The overnight reverse repo operations span working days before and after the tax period, demonstrating the policy intention to meet institutions’ short-term funding needs.

On operation scale, Pang Ming commented that setting a daily cap of RMB 600 billion signals the central bank aims to avoid excessive liquidity injection while keeping liquidity ample. Such flexible regulation satisfies short-term capital demand of financial institutions, prevents idle fund arbitrage, and safeguards stable functioning of the money market.

“The PBOC announced the daily volume cap in advance without specifying exact operation amounts. Actual volumes will likely hinge on real demand from financial institutions, underscoring operational flexibility,” said Wang Qing, Chief Macroeconomic Analyst at Orient Jincheng. The central bank’s regulation over market interest rates has become more precise, and market rates are expected to operate more steadily going forward.

Looking ahead, overnight reverse repos are set to grow in importance, constituting a key component of China’s reform to refine the short-end interest rate regulation framework.

In the China Monetary Policy Implementation Report for the Second Quarter of 2026 released on August 12, the PBOC stated it will gradually raise the frequency of overnight reverse repo operations in response to demands from primary dealers to further smooth transmission from policy rates to market rates. Analysts noted that operation frequency of overnight reverse repos has risen markedly recently.

“Against a complex domestic and external backdrop, such flexible operations are poised to become a vital instrument for the PBOC’s liquidity management,” Pang Ming said. Wang Qing holds the view that overnight reverse repos may gradually replace 7-day reverse repos and evolve into the core policy tool for the central bank’s short-end liquidity regulation.
