Spain and France held decent bond auctions today, with the latter's borrowing costs slipping in a sale of 10-year notes. Spain sold €3.75B of bonds, the top end of its range, with demand rising to 2.69 times the amount sold. However, the average yield rose to 5.544%, the highest in at least six years and up from 4.848% on similar notes auctioned at the beginning of November.
