China's central bank pumped money into the inter-bank market to provide more liquidity. 
The People's Bank of China (PBOC) put 50 billion yuan (around 7.6 billion US dollars) into seven-day reverse repos, a process by which central banks purchase securities from banks with an agreement to sell them back in the future. 
The reverse repo was priced to yield 2.25% , according to a PBOC statement. 
The central bank has adopted repos and other liquidity operations to ease money shortages in the market more frequently this year, rather than cuts in interest rates or the reserve requirement ratio. 
On Monday's interbank market, the benchmark overnight Shanghai Interbank Offered Rate (Shibor) stayed flat at 1.996%.
