    Surging yields test bank deposit betas as BAC checking franchise anchors funding cost

    Question

    Surging yields test bank deposit betas as BAC checking franchise anchors funding cost

    Direct answer

    With the 10-year Treasury yield reaching 5.041%, interest rate dynamics have shifted structural funding advantages across the financial sector. Low-cost transaction accounts, particularly consumer checking balances, serve as a core defensive asset for commercial banks by anchoring cost of funds well below prevailing market rates. Bank of America (BAC) shares have rebounded 25% from their 52-week lows, pushing price-to-earnings, price-to-sales, and price-to-book ratios above their five-year averages. While the stock offers a 2% dividend yield, valuation multiples reflect market recognition of deposit franchise value under higher terminal rate expectations. Unlike mortgage REITs and non-bank lenders that rely on wholesale funding exposed directly to elevated SOFR and Treasury yields, commercial banks retain discretion over retail deposit pricing, supporting net interest spreads despite broader monetary tightening pressures.
