Bank of America has the most asset-sensitive balance sheet among large US banks. Management has disclosed that a 100 basis point parallel shift in rates adds approximately $3 billion in annual net interest income. The recent steepening of the yield curve, where long-term rates have risen faster than short-term rates, is particularly beneficial because it improves the spread on new loan originations and securities reinvestment.
The unrealised loss on the held-to-maturity securities portfolio, which spooked markets during the 2023 regional banking crisis, has been steadily declining as the bonds roll toward maturity. Each quarter, approximately $15 to $20 billion in low-yielding securities mature and are reinvested at current market rates, creating a natural tailwind for net interest income that persists regardless of rate movements.
Historically, the early stage of a rate-steepening cycle has been the optimal entry point for bank stocks. The 2016-2018 cycle saw BAC rally over 80% from its pre-steepening levels. The 2004-2006 cycle produced similar results. We are in the early innings of a comparable dynamic, with the added benefit of a cleaner balance sheet and stronger capital ratios than in either previous period.
The forward PE of 12x implies earnings growth deceleration, but the net interest income tailwind alone suggests 10-15% earnings growth is achievable in fiscal 2026 without any contribution from trading or investment banking. If capital markets activity accelerates (as the rally suggests it might), the upside to estimates is significant.
