BEIJING - China's central bank pumped 250 billion yuan ($38.5 billion) into the market this week to ease liquidity.

The People's Bank of China (PBOC) conducted 40 billion yuan and 30 billion yuan on Friday and Thursday in seven-day reverse repos.

Both injection were priced to yield 2.25 percent, unchanged from Wednesday's injection of 65 billion yuan and Tuesday's injection of 75 billion yuan, according to a PBOC statement.

The move followed a net injection of 40 billion yuan on Monday, said the PBOC.
