BEIJING — A total of 510 billion yuan ($78 billion) of reverse repo contracts are set to mature in China’s money market in the coming week.

China’s central bank has skipped open market operations for the past week, citing sufficient liquidity in the banking system as rising fiscal spending near year-end is sufficient to offset impacts of maturing reverse repos.

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.

Rather than across-the-board rate cuts and reserve requirement ratio adjustments, China has relied more on open market operations to inject or withdraw liquidity at different rates and for different time periods.

China will continue a prudent and neutral monetary policy in 2018 as the world’s second-largest economy strives to balance growth with risk prevention.

“Prudent monetary policy should be kept neutral, the floodgates of monetary supply should be controlled, and credit and social financing should see reasonable growth,” said a statement released earlier this month after the Central Economic Work Conference.
