The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Not sure the Ferengi's belief system quite crosses the line from "guiding philosophy" into "religion", but religions of that sort would fall under Scary Amoral Religion, of the Blue-and-Orange Morality variety.

Money Fetish is the closest I can come up with, though I'm guessing you're looking for a reaction to money as a religious or soulful experience rather than something, uh, physical.
I scanned the Money Tropes index and couldn't find anything closer. You could try to create a proposal at the Launch Pad
to see if there are enough examples to merit a trope page.
The Ferengi afterlife is basically a great big stock market in the sky, if I'm remembering it right, and their funeral rites involve auctioning off slices of their own bodies as souvenirs. Something of a sympathetic/comedic deconstruction in DS 9, like with the rest of that show's portrayal of the Ferengi.
I think it's viable along with other more specific subtropes of Odd Job Gods, as long as there are enough well-written examples.
Money worship is a thing but I can't find a trope for it. Not even a Stock Gods for money. Please tell me if I missed it. Jesus said you can't serve both God and Mammon(money). The Ferengis of Star Trek had a monetary religion. Fred Saberhagen's literature had a Blue Temple for those who worshiped money.
