When you owe money to the UP, some cheap civ, or want to seem weaker, send your money over to a ally and they will keep it safe for a duration or give it back to you over time.
Sadly this service isn't available yet as the company contracted to code this, (Stardock) needs a few months to make and plan and distribute it to the interested parties. (Not to mention they have to like the idea.)
So let's hope for this and a host of other economy dlc in the future.
