質問

Six central banks from Europe, North America and Japan have agreed to take steps to secure an ample supply of currencies, including US dollars and euros, for financial markets. The coordinated measures aim to help financial institutes raise dollar and euro funds smoothly amid the European credit crisis.

The Bank of Japan, the US Federal Reserve, the European Central Bank, the Bank of England, the Bank of Canada and the Swiss National Bank on Wednesday announced plans to take additional measures to stabilize financial markets.

The central banks will borrow dollars from the US Fed to allow banks to secure dollar liquidity at low interest rates.

They will also be able to secure other currencies including euros, British pounds and Japanese yen should the need arise.
