Why Every Company Suddenly Wants to Be a Bank

Look closely at the earnings of your favorite consumer brand and you may find something odd: a fast-growing line of revenue that has nothing to do with what the company ostensibly sells. Payments. Lending. Deposits, in everything but name. The product was the customer acquisition; the finance is the business.

The logic is seductive. A company that already owns the customer relationship can distribute financial products at near-zero marginal cost, and financial products carry margins the core business can only dream about. The airline makes more from its loyalty currency than its aircraft. The retailer's card book out-earns its shelves. Software firms discovered that moving their customers' money is stickier than storing their data.

The balance-sheet creep

The trouble with becoming a bank is that it happens gradually and then all at once. Credit risk arrives quietly, tucked inside "customer financing." Duration risk arrives inside the float. And the discipline that actual banks have had beaten into them by a century of failures — capital buffers, funding diversity, boring stress tests — tends to be exactly what the newcomers skipped.

Everyone wants the bank's margins. Nobody wants the bank's memories.

Regulators, to their credit, have noticed; the perimeter of what counts as a "financial institution" widens a little every year. But regulation follows the map, and the map redraws itself faster than the surveyors can walk it.

Where it settles

The likely end state isn't catastrophe — it's consolidation. The firms treating finance as a product line, with real underwriting and real capital, will keep the margins. The ones treating it as a growth hack will donate a cautionary tale to the business-school curriculum, as tradition requires.

The customer, meanwhile, should enjoy the subsidy phase. When everyone wants to finance you, credit is briefly, gloriously cheap. It never stays that way. It never has.
