I've seen this sort of thing before, and I took an approach very similar to your Scenario 2 but without the 'dummy' column.
I changed the PI of the small table to NOT be the columns that I was joining on (or even to include some columns that I wasn't joining on), in your case maybe use Xchg_Rate if it would give you good distribution.
AND make sure you've got stats on both tables.
I've used that a couple of times and it's worked a treat.
