BEIJING — China's central bank on Sept 26 conducted a total of 135 billion yuan (about $19.2 billion) of reverse repos to maintain liquidity in the banking system.

The amount included 42 billion yuan of seven-day reverse repos at an interest rate of 2 percent, and 93 billion yuan of 14-day reverse repos at an interest rate of 2.15 percent, according to the People's Bank of China.

The move aims to keep stable liquidity in the banking system at the end of the quarter, the central bank said.

A reverse repo is a process in which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.
