What's propping up the Euro?

The Swedish crown has gone up about 15% against the Euro.

Indeed, the krona is now back to a level it has been in 2004.

when they will change their gold etc into cash.

saab, What period of time did it take to increase 15%?

Fundamentals drive currency movements long term.

Cost of carry, arbitrage and speculation muddy the water.

I fear you are "married to a view" on the USD instead of realising that "the trend is your friend".

I don´t know exactly, but I think about a month.
I used to divide with 10 to make it easy. 100 kronor would be 10 Euro.It used to be 9, something. Now I get 11 Euro for 100 kronor.
The Swedish krona is interacting (?) with dollars and the Danish with Euro so now it is much cheaper to go to Denmark than it used to be.
From 1875-1913 the Scandinavian countries had the same value - something like Euro now. It did not work out at all. If 3 so similar countries can´t make it how will 27 very different countries going to work out having the same money.
The three countries were Denmark, Norway and Sweden. Iceland belonged to Denmark at that time.

saab, I agree on the issue of 27 countries belonging to one currency, and expecting it to work. It can't; they all have different economies (manufacturing/agriculture), inflation rates, and potential for economic growth. A country like Germany and France cannot continue to support their common currency when those other countries are unable to pay back the loans. When those countries pay back the loans with interest (high), they are unable to invest in their own country's economy. There is no way it's going to work.

I have always believed that England made the right move by staying with their own currency, but they are hurting because their major trading partners economies are hurting.

D0n´t forget Finland is paying too - and the PIIGS can probably never pay back their loans. In Greece and Portugal the people are striking and demonstrating against that there have to be cuts and savings.
GB has signed a contract to help the poor EU countries, which is just absurd taking in consideration their own problems.
Now EU has suggested special EU taxes - crazy.
One hears so often about the poor people in USA, as a matter of fact there are more poor people in EU than in USA living under the poverty line. What do so many EU people do? Complain about USA, but don´t waste one thought about how it is here.
