SoFi's Margin Expansion Story Gets a Bullish Initiation

An analyst initiated coverage of SoFi Technologies (SOFI) with a bullish view, arguing the digital bank's margin expansion is the real story – not just user growth. The analyst's first-coverage note, published on Seeking Alpha, points to a net interest margin that hit a record in the latest quarter, driven by a deposit mix that keeps funding costs well below the industry average.

SoFi's deposit base now sits at roughly $30 billion, with over 90% in high-yield checking and savings accounts that pay less than the average money-market fund. That gap is the engine. SoFi can lend at competitive rates while still earning a spread that traditional banks, burdened by branch networks and legacy systems, cannot match. The result: a net interest margin above 6%, more than double the regional bank average.

The bear case centers on the personal-loan book, which makes up the bulk of SoFi's lending. Charge-offs have ticked up as the consumer credit cycle normalizes. The analyst acknowledges the trend but notes that SoFi's underwriting, which uses cash-flow data from its banking platform rather than just FICO scores, has kept loss rates inside the company's own guidance. The loan book is seasoning, not deteriorating.

The moat extends beyond the balance sheet. Galileo, SoFi's payments and card-processing platform, now handles over 200 million accounts for third-party clients. That is a recurring revenue stream that grows with the fintech ecosystem, not just with SoFi's own customer base. The Galileo network effect – more clients mean more data, better fraud detection, and stickier integrations – is the kind of advantage that takes years to replicate.

SoFi's stock has pulled back from its highs, partly on macro rotation out of growth names and partly on the charge-off narrative. The analyst argues the margin story is real and not priced in. If SoFi can keep deposit costs low and loan losses contained, the earnings trajectory supports a multiple well above the current 2x book value.

The next catalyst is the July earnings report, where the market will watch for deposit growth and net interest margin stability. A beat on both would force the short thesis to evolve beyond the charge-off scare.

AlphaScala's own scoring system gives SOFI a Mixed rating with an Alpha Score of 35 out of 100, reflecting the tension between the bullish margin story and the elevated charge-off risk.
