US Banks Shift From Bitcoin to Altcoins as Three Tokens Gain Attention

US Banks Drastically Reduce Bitcoin Exposure in Favor of Ethereum, Solana, and XRP

New regulatory data published by the Basel Committee on Banking Supervision (BCBS) reveals a profound rotation in how financial institutions across the Americas are allocating capital across digital assets. According to analysis by Ledger Insights, Bitcoin’s ($BTC) dominance within bank cryptocurrency risk portfolios has nearly halved, falling from 75.8% to 44.2% — a shift that signals growing institutional comfort with alternative Layer 1 networks and a diversification away from the original cryptocurrency as a sole reserve asset.

Ethereum Emerges as Primary Beneficiary of Portfolio Rebalancing

The decline in Bitcoin’s weighting has coincided with a substantial rise in Ethereum ($ETH) exposure, which now accounts for 38.5% of banks’ crypto risk portfolios in the Americas. This near-parity with Bitcoin marks a watershed moment for institutional adoption of the second-largest blockchain by market capitalization. Additionally, Solana ($SOL) and XRP have established measurable footholds, registering 7.8% and 5.6% allocations respectively. The presence of these assets in regulated bank portfolios suggests evolving risk frameworks that now accommodate a broader spectrum of crypto assets beyond Bitcoin.

Total Crypto Risk Exposure Remains Stable Amid Allocation Shift

Notably, the BCBS data indicates no material change in the aggregate cryptocurrency risk held by banks during the reporting period. This stability implies that the observed rebalancing reflects strategic asset rotation rather than a net reduction in digital asset engagement. Banks appear to be actively managing concentration risk by redistributing exposure across multiple protocols, a development consistent with maturing institutional custody and risk management practices.

Client-Driven Trading Activity Surges in Americas, Contracts in Europe

Beyond proprietary holdings, the data captures a sharp divergence in client-facing crypto activity. Transaction volumes executed by banks on behalf of customers in the Americas surged 93% period-over-period, reaching €6.4 billion. In contrast, European banks saw a 25% decline in similar client flows, falling to €1.9 billion. The asymmetry underscores differing regulatory climates and market appetites across jurisdictions, with U.S. institutions capturing a growing share of institutional and high-net-worth crypto order flow.

Why This Matters

The BCBS portfolio data offers the most transparent window yet into how globally systemically important banks are treating digital assets under the evolving Basel III prudential framework. The rotation from Bitcoin toward Ethereum, Solana, and XRP suggests that regulatory capital rules — which assign higher risk weights to less liquid or more volatile assets — may be influencing allocation decisions as much as market conviction. Meanwhile, the explosion in Americas-based client volumes signals that U.S. banks are increasingly acting as on-ramps for institutional capital, even as Europe’s Markets in Crypto-Assets (MiCA) regime continues to take shape. Future BCBS disclosures will be critical for tracking whether this diversification trend accelerates or stabilizes.

Frequently Asked Questions

What does the BCBS data measure exactly?

The data tracks the composition of cryptocurrency risk exposures held by banks in the Americas, expressed as percentage allocations across specific assets, as reported under Basel Committee supervisory standards.

Did banks sell Bitcoin to buy Ethereum, Solana, and XRP?

The data shows a shift in portfolio weightings but does not confirm net buying or selling of any specific asset, as total crypto risk exposure remained stable. The rebalancing could reflect valuation changes, new allocations, or a combination of both.

Why did client transaction volumes rise in the Americas but fall in Europe?

The divergence likely reflects differences in regulatory clarity, institutional adoption curves, and market structure. The U.S. has seen growing custodial and prime brokerage services for crypto, while Europe’s MiCA framework is still being implemented.
