Osama holds my mortgage!

So do I have to pay?

The bank that holds my mortgage (maybe through a subsidiary; I’m not entirely sure of the corporate structure, but I make my checks out to the bank) has been in the news quite a bit lately for doing business with one of the banks on the list of terrorist organizations whose assets must be frozen. As I understand it, if foreign banks do not cooperate with this executive order, they may be cut off from US financial markets.

So, on the off chance that the sanctions actually were imposed, would I have to pay off my mortgage? Note that I’m not expecting an affirmative answer, but it’s nice to contemplate.
