The British pound deepened its decline. It fell below $1.52 Wednesday for the first time since July 2010 after a report showed that the Bank of England was more concerned about Britain's economy. If the country takes on more economic stimulus measures that result in lower interest rates, the pound could fall further.
In late trading, the pound was worth $1.5240 compared with $1.5423 late Tuesday.
The dollar also gained against the Canadian dollar and Swiss franc.
