China's central bank has cut interest rates and lowered the amount of cash banks must hold as reserves, besides freeing up deposit rates, after reporting this week its slowest quarterly economic growth since the global financial crisis.

The People's Bank of China (PBOC) announced on its website that it was reducing lending and deposit interest rates by 0.25 percentage points each (to 4.35%) and its reserve requirement ratio by 0.50 percentage points. 

The central bank also said China's inflation stayed on a lower level overall, leaving some room for a rate cut.

The reduction in the reserve requirement ratio for banks was a pre-emptive move to support liquidity in the banking industry, the PBOC said.

The targeted RRR cut aimed at better supporting the rural sector and small businesses.

Conditions were mature for the removal of a ceiling on deposit rates, the central bank said. After the liberalisation, the PBOC's interest rate adjustment will rely more on market-based monetary policy tools.

A big drop in foreign reserves reported this month by the central bank had a neutral impact on liquidity, it said, adding that the factors that could affect the future level of China's foreign reserves remained unclear.

The central bank said its monetary policy would remain prudent and it would continue to pay close attention to economy and price changes.
