(Yicai Global) Oct. 21 -- The People's Bank of China injected CNY80 billion (USD12 billion) into the financial system by conducting open market operations today.

The bank carried out CNY80 billion in 7-day reverse repos today while no previous ones expired.

The central bank has added CNY200 billion (USD30 billion) to the banking system this week after breaking a long hiatus on Oct. 14.

The purpose is to keep the liquidity of the financial system "reasonably ample," the regulator reiterated in a statement today.
