The Federal Reserve Bank of New York said Thursday it is again increasing the scope of liquidity operations it is willing to offer financial markets to ensure money-market rates remain relatively calm over an uncertain year-end.

The bank, which handles the implementation of monetary policy goals laid out by the rate-setting Federal Open Market Committee, said its provisions of liquidity available via overnight repurchase agreements will rise to $150bn, from the current $120bn cap, in operations planned for between December 31 and January 2.
