"Major-bank Bitcoin adoption is accelerating, but still early: 32% overall as measured by the index." — Michael Saylor, Executive Chairman, Strategy Inc.
Strategy Inc. (formerly MicroStrategy) published its Bitcoin Banking Adoption Index on July 13, 2026, scoring 25 of the world's largest financial institutions at a composite 32% across trading, custody, products, lending, and executive activity. Fidelity topped the ranking at 71%. BNY Mellon scored 46%, Goldman Sachs 45%, JPMorgan Chase 43%, Morgan Stanley 43%, and Citigroup 43%.
The index arrives at a moment when U.S. banks are actively deploying crypto services — Morgan Stanley launched spot crypto trading on E*TRADE on July 16, Citigroup is building institutional Bitcoin custody infrastructure slated for later this year, and BNY Mellon expanded its digital asset custody to Abu Dhabi in May. Yet the index carries a structural disclosure problem: Strategy holds 843,775 BTC ($53.2 billion at current prices) and has published no independent methodology, scoring criteria, or data sources behind its 32% figure.
This report evaluates the index against verifiable bank-level activity, examines what the scores actually measure, identifies gaps in methodology, and assesses the regulatory backdrop enabling these developments.
Strategy CEO Phong Le published the index on X on July 13, 2026, covering public information through July 10, 2026. The index evaluates institutions across the following categories:
Strategy uses "Harvey balls" — graphic circles filled to five levels — to indicate adoption intensity from zero to full implementation. The composite score is an unweighted average across categories, per available reporting. No weighting schema has been disclosed.
Overall score distribution: 71% (Fidelity), 46% (BNY Mellon), 45% (Goldman Sachs), 43% (JPMorgan, Morgan Stanley, Citigroup), 35% (Banco Santander, Société Générale), down to 13% (SMBC, Royal Bank of Canada).
Fidelity's leading position is supported by verifiable activity across every scored category:
Fidelity began researching blockchain in 2014. Its institutional custody platform is built in-house, differentiating it from peers that outsource to Coinbase or BitGo.
The world's largest custodian ($59.4 trillion in assets under custody) entered digital asset custody in 2022 and expanded to Abu Dhabi Global Market in May 2026 for Bitcoin and Ethereum. BNY serves as administrator, transfer agent, and cash custodian for Morgan Stanley's proposed Bitcoin ETF. Tokenized deposits launched on its digital assets platform in January 2026.
Goldman holds approximately $1.6 billion in Bitcoin ETF positions per recent SEC filings. The bank filed for a Goldman Sachs Bitcoin Premium Income ETF — an options-overlay strategy generating income from Bitcoin exposure. Goldman participated in the nine-bank consortium (alongside Deutsche Bank, BofA, Santander, BNP Paribas, Citi, MUFG, TD Bank, and UBS) developing a jointly backed stablecoin for G7 currencies.
JPMorgan's digital assets division, led by Scott Lucas, confirmed plans to develop cryptocurrency trading for institutional clients. The bank announced a partnership with Coinbase allowing Chase credit card holders to fund crypto purchases. JPMorgan does not offer custody and has stated it will not do so in the near term. Its Onyx blockchain platform processes $3 billion in daily settlements but focuses on tokenized deposits and repo, not direct Bitcoin services.
Morgan Stanley completed E*TRADE spot crypto rollout on July 16, 2026, offering Bitcoin, Ethereum, and Solana through Zero Hash accounts at 50 basis points per trade. The bank filed with the OCC on February 18, 2026, seeking authority to directly custody digital assets, execute trades, and facilitate fiduciary staking. Coinbase and BNY Mellon are named custody partners for its proposed Bitcoin Trust structure.
Citi has been building institutional-grade custody infrastructure for two to three years, per global head of partnerships Biswarup Chatterjee. The 2026 launch covers custody, key management, and wallet infrastructure. Clients will hold Bitcoin alongside conventional assets without managing private keys. Citi also participates in the nine-bank G7 stablecoin consortium.
Banco Santander and Société Générale sit near 35% in the index. Verifiable activity supports these mid-range scores:
Only 8 of the top 20 EU banks have live crypto services at scale, according to Coinpedia's July 2026 analysis. Most remain in pilot or announcement phase.
SMBC and Royal Bank of Canada scored lowest at 13%. MUFG Bank participates in the nine-bank stablecoin consortium but has limited direct Bitcoin service offerings visible in public disclosures. Japanese banking regulations impose additional compliance requirements that slow retail-facing crypto launches.
The acceleration in bank crypto service deployment traces directly to two regulatory shifts:
SAB 121 Rescission (January 2025): The SEC withdrew Staff Accounting Bulletin 121, which had required banks to record crypto held for customers as balance-sheet liabilities. This made custody economically impractical for institutions subject to capital adequacy rules. The replacement, SAB 122, reverts to standard contingency-liability accounting under existing FASB/IAS guidance.
OCC Interpretive Letter 1184: Confirmed national banks may provide and outsource crypto-asset custody and execution services. Banks may buy and sell assets held in custody at customer direction, subject to third-party risk management requirements.
These two actions removed the primary structural barriers that had prevented traditional custodians from competing with crypto-native firms like Coinbase, BitGo, and Anchorage. The result: BNY Mellon, State Street, Citigroup, and Morgan Stanley all announced or expanded custody platforms within 12 months of rescission.
Strategy's index presents several unresolved methodological questions:
No published scoring rubric. The criteria determining how Harvey ball levels map to percentage scores have not been disclosed. A bank scoring "2 out of 5" in custody could mean anything from pilot phase to partial deployment.
No weighting transparency. Whether custody carries equal weight to corporate allocation, or whether trading outranks stablecoin activity, is unknown. This matters: a bank with $500 billion in custody but no corporate BTC allocation could score identically to one with a small treasury position but no custody.
No data source verification. Le's post stated scoring relies on "public information" but did not identify specific filings, press releases, or regulatory disclosures used.
No independent audit. The scores have not been verified by a third party. Le invited institutions to submit corrections, suggesting the data set is approximate.
Sample selection criteria. The index covers "roughly 30" institutions selected by total assets, AUC/AUA, client assets, private-banking assets, and G-SIB status. The exact list and selection thresholds are not published.
Per TFTC's analysis: "The methodology matters more than usual... Until that detail is public, 32% is a claim, not a settled fact."
Strategy holds 843,775 BTC with a cost basis of $63.69 billion (average $75,482 per coin). At Bitcoin's current price of approximately $63,900, the position carries an unrealized loss of roughly $10 billion.
The Bitcoin Banking Adoption Index constructs a narrative favorable to Strategy's thesis: that bank adoption is inevitable, accelerating, and currently undervalued. A rising index would imply growing institutional demand — a dynamic that, if realized, supports the price of Strategy's single largest asset.
This does not invalidate the index's directional claim. Bank crypto activity is verifiably expanding across multiple institutions. But the index's utility as an objective benchmark is limited until methodology is independently verifiable.
The Bitcoin Banking Adoption Index captures a real phenomenon: major financial institutions are building crypto infrastructure at a pace not seen before 2025. The regulatory environment — particularly SAB 121's removal and OCC's expanded custody guidance — has made bank participation commercially viable for the first time.
However, the index itself remains an advocacy tool rather than an analytical instrument. Without published methodology, independent verification, or transparent weighting, the 32% figure functions as a marketing claim from the world's largest corporate Bitcoin holder.
The underlying data is more useful than the index score. Morgan Stanley's E*TRADE launch serves 15 million accounts. BNY Mellon's custody infrastructure supports $59.4 trillion in traditional assets. Citigroup's three-year custody build-out represents a multi-hundred-million-dollar infrastructure commitment. These are verifiable, material developments.
What remains unknown: whether this activity represents structural adoption of Bitcoin as a permanent bank product line, or a cyclical response to client demand that scales with price. The next 12 months of bank revenue disclosures from digital asset divisions will answer that question more reliably than any index.
