SHANGHAI, Aug 16 (Reuters) - China’s central bank injected billions of yuan through medium-term loans into the financial system on Monday, while keeping the interest rate unchanged for the 16th month in a row. The People’s Bank of China (PBOC) kept the rate on 600 billion yuan ($92.64 billion) worth of one-year medium-term lending facility (MLF) loans to some financial institutions steady at 2.95% from previous operations. The PBOC said in a statement that the operation was a rollover of 700 billion yuan of maturing MLF loans due on Tuesday, and effectively drained 100 billion yuan of mid- to long-term liquidity from the banking system. The central bank also injected another 10 billion yuan worth of seven-day reverse repos into the banking system on the day.
