The People's Bank of China injected 10 billion yuan (about 1.52 billion U.S. dollars) into the market through seven-day reverse repos at an interest rate of 2.2 percent, according to a statement on its website.
With 120 billion yuan of reverse repos maturing on the same day, this led to a net liquidity withdrawal of 110 billion yuan from the market.
A reverse repo is a process in which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.
China's central bank has pledged to make its prudent monetary policy more targeted and flexible to adapt better to the needs of high-quality development and put more focus on the efficiency of financial services to support the real economy.
More efforts will go into improving the money supply regulation mechanism to maintain reasonable and sufficient liquidity, the PBOC said in its third-quarter monetary policy report last week, ruling out the possibility of a "flood-like" stimulus.
