Deposit Franchise Value
Deposit franchise value is the economic worth of a bank's ability to fund itself below market rates through its deposit relationships. It doesn't show up as a line item on the balance sheet, but it's the primary reason some banks consistently trade at premiums to tangible book value while others trade at or below.
The Concept
Consider a bank with $5 billion in deposits at an average cost of 1.5% when wholesale funding of similar maturity costs 4.0%. The bank saves 250 basis points on $5 billion, or $125 million per year in funding costs compared to a bank that had to borrow at market rates. If you capitalize that annual savings at a reasonable multiple, the deposit franchise is worth well over $1 billion, none of which appears on the balance sheet.
This is why acquirers pay premiums above tangible book value in bank M&A. They're buying not just the reported net assets but the right to that ongoing funding advantage.
What Makes a Franchise Valuable
Four factors determine deposit franchise value:
The proportion of non-interest-bearing deposits. NIB accounts cost nothing and tend to be the stickiest. A bank where 35% of deposits pay no interest has a much more valuable franchise than one at 15%.
Deposit stability through rate cycles. Banks that retain deposits without having to chase rates demonstrate genuine relationship value. Those that hemorrhage deposits every time a competitor offers 25 extra basis points have a weak franchise.
The longevity and depth of customer relationships. Banks with customers who hold checking accounts, savings accounts, loans, and other products are far harder to displace than those with single-product relationships.
Geographic and demographic factors. Banks in growing, affluent markets with limited competition have structurally better deposit-gathering environments than those in declining or saturated markets.
How It Connects to Valuation
Deposit franchise value explains persistent P/TBV premiums. A bank trading at 1.8x tangible book when a peer trades at 1.1x isn't necessarily overvalued. The premium reflects the market's assessment that the first bank's deposit franchise generates more economic value than its tangible assets alone would suggest.
When evaluating whether a bank's stock price is justified, back into the implied franchise value. If a bank has tangible book value of $30 per share and trades at $48, the market is ascribing $18 per share, or roughly $600 million on a base of 33 million shares, to franchise value. Is that reasonable given the bank's deposit cost advantage, its stability, and its growth market? That's the question worth answering.
