EIJING, Sept. 12 -- The People's Bank of China (PBOC), the country's central bank, skipped open market operations via reverse repos on Thursday.

The PBOC announced the decision in a terse statement on its website, citing reasonably sufficient liquidity in the banking system.

No reverse repos matured Thursday.

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 will keep its prudent monetary policy "neither too tight nor too loose" while maintaining market liquidity at a reasonably ample level in 2019.
