As was widely expected, the ECB kept its key rate at a record low 0.5 per cent at a meeting today.
"The risks surrounding the economic outlook for the euro area continue to be on the downside," Draghi warned. "The recent tightening of global money and financial market conditions and related uncertainties may have the potential to negatively affect economic conditions. Other downside risks include the possibility of weaker-than-expected domestic and global demand and slow or insufficient implementation of structural reforms in euro area countries."
The euro slid against the US dollar, declining 0.6 per cent.
The UK's FTSE 100 jumped 3.1 per cent after the Bank of England kept its benchmark rate steady at a record low as well and suggested it is there to stay.
"The implied rise in the expected future path of Bank Rate was not warranted by the recent developments in the domestic economy," the BOE said in a statement.
The British pound weakened as a result, sliding 1.4 per cent against the greenback.
"The [BOE] statement is probably a little bit more dovish than the market was expecting, pushing back on the rise in longer-term interest rates and suggesting that monetary policy will remain accommodative for some considerable time," Paul Robson, a senior currency strategist at Royal Bank of Scotland Group in London, told Bloomberg News. "This leaves sterling vulnerable against the [US] dollar and the euro."
