Only because you didn't.
Try again, if I borrow gold based money, does the money supply increase?
Maybe it would help if you learned what actually makes up the money supply. I'll wait.
Sure I did. Your failure to admit it notwithstanding.

Think about it some more...
If 10 oz of gold is all the gold in the world and you borrow 10 oz @ 5% interest, the total gold supply must increase by 1/2 oz or you cannot pay the gold loan plus interest one year later. Either I don't get all my gold back or the lender doesn't get his 1/2 oz of interest.
