Money Soft Cap Limit

I was farming some mobs for a while with a cash grenade equipped and hit the soft cap for money. I can't remember how BL or BL2 handled the cap, if it was a hard or soft cap in that game, but it appears that BL3 treats it as a soft cap.

I got the max amount that will show in the UI: $99,999,999. I then tested it by going to a vendor and buying a bunch of stuff. The amount never changed, so if you're farming cash and hit the limit, you should still be accruing money even though it doesn't show it.
