Hmm.  I've recently started using Gnucash and set up most of my
accounts in GBP except for a bank account (under Assets of course)
*and* a related 'Income:Interest:USA' account in USD.  (Everything
else in the Income subtree is in GBP.)

It seemed logical at the time --- am I setting myself up for trouble
later?
