Wells Fargo (WFC, USD): a very large spread-and-fee bank whose engine is improving, but not becoming more powerful.
Wells Fargo’s DNA is simple: it gathers very cheap funding via deposits, lends and invests that money at higher yields, and layers on fees from cards, wealth management, treasury services, capital markets, servicing, and advisory. The core economic machine is still deposit franchise + credit underwriting + operating leverage. This is not a software-like compounding model; it is a scaled balance-sheet business.
The business is headed toward better profitability, but only modest underlying growth. As of Q2 2026, average loans were up 11% year over year, deposits up 8%, total revenue up 8%, net income up 12%, and the efficiency ratio improved to 64 from 67 in the prior-year first half. That says the engine is currently strengthening. But one important counter-signal is that net interest margin fell to 2.45% from 2.67%, so some of the improvement is coming from volume growth, mix, and expense discipline rather than a structurally stronger spread business.
This is mostly a win-win model when run properly: customers get payments, credit, liquidity, advice, and treasury infrastructure; businesses get working capital and capital markets access; Wells earns spreads and fees for managing risk and distribution. The historical caveat is culture. Banks can destroy trust when sales incentives outrun customer value. Wells has already lived that lesson. So the key question is not whether banking is useful; it is whether Wells can earn returns without reverting to extractive behavior.
Long term, the main deterioration risks are not product obsolescence but franchise erosion: shrinking deposit share, weaker fee businesses, credit deterioration, or inability to grow core households and commercial relationships. Right now, the evidence is mixed-positive: earnings power is improving, but the business still looks like a mature bank optimizing within constraints, not a franchise entering a new growth phase.
If I tracked only five numbers: deposits, average loans, net interest margin, efficiency ratio, and credit losses / charge-offs.
