The Icelandic krona?s sharp fall, which put it at a 4?-year low against the euro on Tuesday, has provoked debate between political and business leaders about the country?s possible membership in the eurozone.

In the past few weeks, both Halldor Asgrimsson, prime minister, and Sigurdur Einarsson, chairman of Kaupthing Bank, have raised the possibility of abandoning the volatile krona, which has come under pressure from concerns that acquisition-hungry Icelandic companies have overstretched themselves and the wider economy by taking on too much foreign debt.
