China's central bank skipped open market operations Monday to maintain stable liquidity in the banking system.
Liquidity was at a "relatively high level," which can offset the influence from factors such as maturing reverse repos, the People's Bank of China (PBOC) said on its website.
On Monday, reverse repos worth 40 billion yuan (about 63.5 billion U.S. dollars) matured.
A reverse repo is a process by which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.
The central bank has increasingly relied on open market operations for liquidity management, rather than cuts to interest rates or reserve requirement ratios.
China will maintain a prudent and neutral monetary policy in 2018 as the world's second-largest economy strives to balance growth with risk prevention.
