The compensation required by investors to hold French treasury bonds rather than Italian treasury bonds has risen to the highest level since the euro was founded. On Friday, the difference in yield between the two countries' benchmark 10-year treasury bonds reached a record 30 basis points. Until last year, Italy was considered the riskier side of the two countries, and its borrowing costs were higher than France's.
