China's central bank pumped 50 billion yuan ($7.85 billion) into the money market via reverse re-purchase agreement (repo) on Tuesday, the first cash injection this week.
The yield for the seven-day reverse repo stood at 2.35 percent, Xinhua news agency quoted the Bank of China's (PBOC) statement as saying.
Under a reverse repo, the central bank purchases securities from large banks and brokerages with the agreement to sell them in the future as an effective means to tackle short-term money shortages in the market.
The cash injection will offset the effects from earlier reverse repo due on Tuesday.
Given a stable renminbi (RMB), the money shortage was greatly eased in September and the PBOC's operations were smaller than those in August.
