This chart shows the cumulative injection of funds by The People's Bank of China (PBoC) into the Chinese banking system since 2009 compared against weekly net injections. Since January 2009, the PBoC has injected 4.3 trillion RMB with 80 percent of that amount (3.5 trillion RMB) being issued since the beginning of 2011. Meanwhile, banks' claims on other financial institutions (i.e. interbank assets) have more than doubled, increasing 108 percent from the end of 2010 to September of this year (the latest available data). The juxtaposition of the two data sets illuminated the
dynamics driving tightness in interbank liquidity.
