Rebuffing market expectations, China’s central bank has left an interest rate on reverse repurchase agreements unchanged when using the monetary policy tool after a nearly two-month hiatus.

The People’s Bank of China (PBOC) injected 130 billion yuan ($18.2 billion) into the money market via seven-day reverse repos on Tuesday (link in Chinese) and Wednesday (link in Chinese) with a 2.2% interest rate, the same rate as the previous repos on March 31 (link in Chinese). The agreements are a tool used by central banks to add to or reduce money supply via open market operations.
