Mario Draghi on ECB rate cut decision
4 September 2014 Last updated at 18:32 BST
The European Central Bank has cut its benchmark interest rate to 0.05%, and introduced new stimulus measures.
The bank will also start buying up private-sector bonds.
It is trying to make credit cheaper, to get banks to lend to businesses, and to fight deflation which, if unchecked, could lead to a downward spiral of lower prices, lower wages and job losses.
But not everyone on the bank's council goes along with the plan - as the ECB's President Mario Draghi explained.
