The European Central Bank has cut its main interest rate to a new record low.
It also plans to spend about 60 billion euros ($US80 billion) buying covered bank bonds in a bid to stem the euro zone's economic decline.
The latest cut by 0.25% of a point on Thursday, took the main refinancing rate to 1%. The reduction was expected.
The ECB has now lowered its rates by 3.25 percentage points in the past eight months.
President Jean-Claude Trichet said it left benchmark credit costs at an "appropriate" level.
Also as expected, the Bank of England left rates unchanged at 0.5% earlier on Thursday.
