The US dollar is not far off a one-week high versus its rivals amid uncertainty in global markets, predominantly resulting from concerns over a significant downturn in world economies. The weekend’s dramatic events in Russia have also put traders on alert. The dollar steadied at 102.71 against a basket of currencies, while the euro was last up 0.07% at $1.0902, having fallen to a one-week low on Friday following figures that revealed the euro zone economy had slowed. Sterling rose 0.1% to $1.27285, reversing some of its 0.8% fall last week driven by BOE's rate increase that raised fears of a British recession.
