The British pound is falling near its 2011 low versus the dollar after the Bank of England hinted that it might buy government bonds to support England's economy.
Policymakers at the central bank's September meeting said that weak economic data might make more action necessary.
Bond-buying would make the pound less attractive to traders. Interest rates would fall, limiting their returns on some investments. The money supply would increase, diluting the value of pounds held by traders.
At 11 a.m. Eastern time, the pound fell to $1.5578, the lowest since January 11.
The Swiss franc continued to sink on published reports that the Swiss central bank will set a weaker target exchange rate against the euro.
The dollar rose against the euro and other major currencies.
