Love this skit. Actually if you count Hephaestus (god of blacksmithing and forging) that's three gods of war in the 12 Olympians. As for Greek god of "finance", Plutus and Hermes was I close as I could find. Plutus being the god of wealth and Hermes being trade and diplomacy(as well as theft and animal husbandry...no really). Hundreds of gods and none of them are commerce, finance, money, or economy.

Hundreds of gods and none of them having to do with wealth?

No wonder Olympus died out. Poor fiscal discipline!
