Swap lines for EU banks are now discounted to 0.58 percent. The European Central Bank gives us euros as collateral, and we give them dollars at that rate.
Most American banks are paying much more for dollar loans, either 0.75 percent or 1.25 percent, at our own discount window. Seasonally adverse conditions allow some US banks to borrow at 0.25 percent.
The reason the EU gets such a break? Maybe because the EU is in big, big trouble, Trouble with a capital "T".
