Danish Euro adoption looks to be a marginal case.

A small majority of Danes favour adopting the euro in place of Denmark's crown, but a referendum would turn out to be an extremely tight race. A poll taken in September indicated that 38.4 percent of Danes said they would adopt the euro while 37.8 percent were against.

Adoption of the Euro was rejected by the Danish government in 2000 on the back of a referendum however it would seem people have warmed towards the European currency at the end of last year when the financial crisis deepened and consumers found their wallets hit by high interest rates.

That pressure has eased as the Danish central bank began cutting its key interest rate from 5.50 percent in November 2008. The lending rate now stands at 1.35 percent. The bank's monetary policy aims to keep the crown steady within a narrow band to the euro.

Denmark's centre-right government has said a vote before 2011 is not on the cards even though the governing coalition partners favour the euro. Denmark has opt-outs from European Union co-operation in the areas of monetary policy, defence, justice and home affairs.

The Danish government wishes to eliminate all the exemptions, and has said it will hold a referendum on them when the time is right and when it would be certain to prevail.
