Power
Credit analysts hold a fair amount of sway in their companies. That shouldn't be too surprising; when your job description is basically "help make important decisions," you're bound to actually make some important decisions. And those decisions will affect people in all sorts of interesting ways.
Working for a big firm will place you on teams that decide how much a well-known company could expand, or whether or not it'll close for good. You'll be the one to dig into people's bank records and find a narrative that spells either "happily ever after" or "and it all ended with financial ruin."
Of course, the bigger the financial impact of the decision, the more people will inevitably be involved in approving it. And as the number of cooks in the kitchen grows, the less instrumental you actually are in making the dough. That's the power balance of the credit analyst: the more important the deal, the less important you are, individually, in making it.
