(Yicai Global) Oct. 9 -- The People's Bank of China passed on open market operations again today, effectively pulling cash out of China's monetary system for the fourth straight day.

Some CNY20 billion (USD2.8 billion) worth of reverse repos mature today, and the central bank's inactivity will see all of this withdrawn from the financial system.

The central bank reiterated again that liquidity is currently at a high level and there is no need to increase it. It skipped OMOs with the same message yesterday and on the last two trading days before the week-long National Day holiday, Sept. 29 and Sept. 30.
