BEIJING, Nov. 21 -- China's central bank said Friday that it will inject liquidity into the country's banking system if necessary.

　　"At present, the overall liquidity in the banking system is abundant," the People's Bank of China (PBOC), the central bank, said in a posting on its official microblog on Sina Weibo.

　　Recently, there have been fluctuations in short-term capital supply and demand and money market interest rates, according to the PBOC, citing factors including the initial public offerings of several companies next week.

　　"If necessary, the central bank will provide timely liquidity support via multiple monetary policy tools," the central bank said.
