China's central bank has responded to the U.S. Federal Reserve's interest rate increase by nudging up a key policy rate on lending to commercial banks but left the benchmark rate for borrowing by companies and the public unchanged.

The People's Bank of China said Thursday it was responding to market forces by raising the rate charged by its one-year lending facility by 0.05 percentage points to 3.25 percent. Rates paid on bank reserves rose by a similar margin.

There was no change in the rates for borrowing by companies and the public and for deposits.

Beijing has tightened controls on the movement of money out of China to stop an outflow of capital, which could be worsened if higher U.S. rates attract investors with the possibility of higher returns.
