BEIJING - The People's Bank of China (PBOC), the central bank, on Friday continued to pump cash into the financial system through open market operations to maintain liquidity in the market.

The PBOC conducted 100 billion yuan ($14.57 billion) of seven-day reverse repos, a liquidity-injecting process in which the central bank purchases securities from commercial banks through bidding with an agreement to sell them back in the future.

The move followed a similar operation of conducting 100 billion yuan of seven-day reverse repos on Thursday. The interest rate for the operation remained at 2.55 percent, the PBOC said in a statement.

The operation is aimed at maintaining reasonable liquidity in the financial system, it added.

This week's open market operations via reverse repos and medium-term lending facility have led to a net liquidity injection of 471.5 billion yuan.

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