Bitcoin Banking Adoption Index Hits 32% Across 25 Major Banks

Strategy's new Bitcoin Banking Adoption Index lands at 32% across 25 major banks and financial institutions, a depth score measuring how far the traditional finance stack has built out custody, trading, investment products, lending, and leadership support for the asset. The figure is intentionally narrow: it tracks plumbing, not coin ownership.

That distinction is the story. Bitwise's Q3 2026 Crypto Market Review estimates individuals hold 66.1% of Bitcoin's 21 million maximum supply, roughly 13.9 million BTC, versus 7.8% held by businesses and 7.2% held by funds and ETFs. Businesses plus funds combined control only about 15% of supply, or roughly 3.15 million BTC, leaving individuals with close to 4.4 times the BTC of both groups put together. Banks are not chasing coin; they are chasing the accounts of the people who already own it.

Why it matters

The order of operations is unusual for a financial product. Individuals built the ownership base years before any major bank built a custody desk, which means banks are entering a market that already exists rather than creating one from scratch. Customer demand, ETF growth, corporate treasury activity, and competition from crypto-native firms are all cited as drivers behind the 32% score.

Regulatory tailwinds have removed the frictions that held banks back. The SEC's SAB 122 rescinded SAB 121, dropping the balance-sheet liability treatment that institutions had cited as an obstacle to scaling crypto custody. The Federal Reserve folded advance-notice requirements for state member banks into ordinary supervision, and the OCC confirmed national banks can buy and sell crypto held in custody at a customer's direction. The Basel Committee's crypto-asset disclosure framework took effect January 1, 2026, adding a reporting layer for internationally active banks.

Market impact

The index sketches two competing paths. In the capture path, a slice of the 13.9 million BTC moves onto bank-controlled rails: 10% equals roughly 1.39 million BTC, 25% reaches about 3.47 million, and 50% approaches 6.94 million.
