Sterling hit a record low against a basket of currencies on Monday, according to a Bank of England data series going back to 1990, taking it to within five pence of parity against the euro.
The pound sank to a record low against the euro on Thursday last week to its closest with parity since the single currency's inception a decade ago.
The pound has been battered by sharp reductions in interest rates to historic lows, a falling housing market and a growing perception that the economy will be among the biggest casualties from the global financial crisis owing to its high dependence on financial services, high consumer and household indebtedness, and deteriorating public accounts.
Sterling is now down 22 percent on the year to date against the euro and 25 percent against the dollar.
Following are some recent milestones for the pound, going back to 1990:
December 22, 2008 - As trading winds down ahead of the year-end holidays, the trade-weighted pound falls to 75.90, bringing that broad measure of sterling down 22 percent year to date.
The pound is also down 22 percent so far this year against the euro, on track for by far its largest ever annual fall against the 10-year old euro. Sterling, down 25 percent against the dollar, is on track for its worst year against the greenback in over a quarter of a century.
