The U.S. Federal Reserve Board announced another round of deals with other central banks that are designed to increase liquidity.

The Fed, the Reserve Bank of Australia, the Danmarks Nationalbank, the Norges Bank, and the Sveriges Riksbank are announcing the establishment of temporary reciprocal currency arrangements (swap lines), “to address elevated pressures in U.S. dollar short-term funding markets.”

These new facilities will support the provision of U.S. dollar liquidity in amounts of up to US$10 billion each by the Reserve Bank of Australia and the Sveriges Riksbank and in amounts of up to US$5 billion each by the Danmarks Nationalbank and the Norges Bank.

“These facilities, like those already in place with other central banks, are designed to improve liquidity conditions in global financial markets,” it said

These new facilities represent a US$30 billion addition to the US$247 billion previously authorized temporary reciprocal currency arrangements with other central banks: European Central Bank (US$110 billion), Bank of Japan (US$60 billion), Bank of England (US$40 billion), Swiss National Bank (US$27 billion), and Bank of Canada (US$10 billion).

These reciprocal currency arrangements have been authorized through Jan. 30, 2009.
