The euro traded down to a one-year low of $1.3856 against the dollar, before recouping some ground to stand down 1 per cent at $1.3882. The single currency also lost 0.7 per cent to £0.7856 against the pound and dropped 1.5 per cent to Y146.14 against the yen.
The dollar rose 0.3 per cent to $1.7660 against the pound, climbed 0.7 per cent to SFr1.1322 against the Swiss franc and gained 0.5 per cent to $0.7865 against the Australian dollar.
The dollar lost ground against the yen, however, easing 0.4 per cent to Y105.36, as a drop in Asian equities heightened risk aversion and boosted the safe-haven appeal of the low-yielding Japanese currency.
