The 2-year is near 50%. I don't think I've ever seen sovereign bond rates this high. A Greek default would send shock waves throughout Europe. http://www.bloomberg.com/apps/quote?ticker=GGGB1YR:IND
The last time I saw a quote of something in the area of 82% was when Enron was in trouble. We all know how that ended.
So if you buy Greek bonds the Greek government will repay you your money with 82% interest added ontop??
