SHANGHAI, Jan 5 (Reuters) - The People's Bank of China (PBOC) conducted a

net drain of 20 billion yuan ($3.21 billion) from the banking system this week,

with operations extending to the weekend due to a national holiday to mark the

new calendar year.

The PBOC injected a net total of 1.438 trillion yuan in 2012. The central

bank also reduced banks' required reserve ratio twice, in February and again in

May, injecting an estimated 800 billion yuan into the banking system.
