The People's Bank of China announced on August 12th that to better align with short-term liquidity needs in the banking system, it will conduct overnight reverse repo operations on August 14th and from August 17th to August 19th.

These operations will use a fixed interest rate and quantity-based bidding, with a daily cap of no more than 600 billion yuan. Ming Ming, Chief Economist at CITIC Securities, noted that because August 15th is a Saturday, August 17th serves as both the reserve requirement date and the tax payment deadline.

The scheduled overnight reverse repo operations cover the trading day before the tax period, the tax payment settlement day, and the two subsequent trading days. Combined with the overnight funding term, this clearly reflects a policy intention to meet short-term funding demands.

"This marks the central bank's first mid-month overnight reverse repo operation, primarily aimed at alleviating the temporary market liquidity tightening caused by tax payment settlements, and guiding the market overnight rate (DR001) to trade smoothly around the policy rate," said Wang Qing, Chief Macro Analyst at Dongfang Jincheng.

Looking back, the People's Bank of China increased overnight reverse repo operations in June and conducted its first operation at the end of that month. In July, the central bank announced overnight reverse repo operations from July 29th to 31st and again on August 3rd.

Notably, in previous overnight reverse repo operations, the central bank specified the daily operation size. However, this time, it has only set a ceiling of no more than 600 billion yuan per day. In Wang Qing's view, this advance announcement of the upper limit without a fixed amount demonstrates operational flexibility, as the actual operation size will depend on the real demand from financial institutions.

Overall, the frequency of overnight reverse repo operations is gradually increasing. It is expected that the People's Bank of China will conduct further such operations at the end of August, which should also help reduce the volatility of DR001.

"The People's Bank of China is accelerating its transition toward a price-based monetary policy framework, but the fundamental policy stance of maintaining ample liquidity remains unchanged," Wang Qing added. He believes future market interest rate trends will become more stable, with rate levels primarily following policy rate adjustments. Factors such as tax payment settlements, government bond issuance settlements, maturing policy tools, and month-end bank assessments will have a diminishing impact.
