SKN | The UK Crypto Regime: What HNW Families Should Reassess Before 2027

Key Takeaways:

• The UK has moved from a largely AML-focused crypto framework toward a broader financial-services regime, with FCA authorisation applications now open and full implementation scheduled for 25 October 2027.
• The new framework covers activities including cryptoasset trading platforms, safeguarding, dealing and arranging, qualifying stablecoins and certain staking activities.
• For HNW families, FCA authorisation should become one element of counterparty due diligence rather than a substitute for reviewing custody, liquidity, governance and financial resilience.
• Digital assets should remain clearly separated from the family’s strategic Swiss custody and liquidity architecture, with documentation strong enough to satisfy banks across jurisdictions.

The UK is entering a new phase of crypto regulation. From 30 September 2026, firms can apply for FCA authorisation under the new regime, while the main framework is scheduled to come into force on 25 October 2027. Existing crypto businesses do not automatically receive the new permissions: firms within scope must apply during the transition period to continue relying on the applicable savings and transitional provisions. For HNW families, this is not simply a regulatory milestone. It is an opportunity to reassess which digital-asset counterparties belong in a sophisticated international wealth structure.

Move From “Registered” to Proper Counterparty Due Diligence

The distinction between the old and new regimes matters. UK crypto businesses have already been subject to FCA registration for anti-money-laundering purposes, but that registration is not equivalent to full financial-services authorisation.

The new regime brings broader requirements covering areas such as consumer protection, safeguarding, market integrity and financial resilience. The FCA has specifically identified trading platforms, dealing and arranging, custody or safeguarding, qualifying stablecoins and staking among the activities that can fall within the new framework.

For private clients, this creates a more useful due-diligence question: not simply whether a platform is present in the UK, but precisely which regulated activities it is authorised to conduct and under which legal entity.

Keep the Digital-Asset Layer Separate From Strategic Custody

A family with significant digital-asset exposure should resist the temptation to treat regulatory authorisation as evidence that a crypto platform is equivalent to a traditional private bank.

Zurich and Geneva institutions provide a different combination of custody, credit, governance, reporting and succession capabilities. A digital-asset platform may instead be valuable for execution, liquidity access or blockchain-native infrastructure.

Keeping those functions separate can reduce operational contagion. The family’s core securities custody, strategic liquidity and Lombard financing do not need to depend on the same institution handling digital assets.

Prepare for More Sophisticated Bank Compliance Reviews

The regulatory transition is also likely to increase the importance of documentation for wealthy clients whose assets originated in crypto. Swiss and UK banks will remain focused on source of wealth, source of funds, beneficial ownership and transaction history.

For digital assets, the evidence trail should be particularly clear. Families should be able to demonstrate acquisition history, wallet ownership, transfers between exchanges and self-custody, conversion into fiat currency and the relationship between those transactions and declared wealth.

This becomes especially important when assets move between Switzerland, the UK and other jurisdictions. A well-documented digital-asset history can reduce unnecessary friction during onboarding, large transfers or periodic compliance reviews.

Watch the 2027 Authorisation Divide

The application window runs from 30 September 2026 to 28 February 2027, ahead of full commencement in October 2027. Firms applying within the relevant window may, subject to the applicable conditions, continue specified activities while their applications are assessed. Firms that do not secure the necessary permissions will face a different operating environment once the new regime takes effect.

That creates a practical monitoring exercise for HNW clients. Platforms used by the family should be reviewed for their authorisation status, legal entity, safeguarding arrangements, jurisdictional reach and ability to support institutional clients.

Make Regulation Part of the Wealth Architecture

The UK regime should ultimately make the digital-asset market easier to assess, but regulation does not eliminate counterparty risk. It changes the information available for evaluating it.

For globally mobile families, the strongest architecture remains deliberately layered: regulated digital-asset infrastructure where appropriate, independent Swiss strategic custody, diversified banking relationships and portable documentation that can withstand scrutiny across jurisdictions. The objective is not to exclude digital assets from sophisticated wealth structures. It is to ensure that their operational and regulatory risks remain contained.
