(Yicai Global) Oct. 17 -- China's interbank rates were a mixed bag again today as short-term interest rates slid, contrasting a rise in longer term lending.

The overnight Shanghai Interbank Offered Rate moved 10.90 basis points lower to 2.5850 percent and the one-week rate was down 2.30 bips at 2.6630 percent. The SHIBOR for three-month loans edged 0.40 percent higher to 2.7360.

The People's Bank of China opted to maintain liquidity in the monetary system today, skipping open market operations while no reverse repos matured. The central bank injected CNY200 billion (USD28.2 billion) into the financial system yesterday, its first interference in 10 trading days.

It reiterated in a statement that liquidity in the nation's monetary system was still "reasonably ample."
