Crypto Wealth Meets Property Finance

Ten years ago, few would have predicted that digital assets such as Bitcoin and Ethereum would play a role in UK property finance. Today in 2025, that prediction has become reality. A growing number of buyers—particularly high-net-worth individuals, entrepreneurs and international investors—hold a significant portion of their wealth in crypto.

But crypto wealth does not translate easily into mortgage approvals. Mainstream lenders remain cautious, many still refusing to accept digital assets as proof of funds or income. Even where crypto gains have been crystallised into fiat currency, anti-money laundering (AML) and source-of-wealth checks can delay or derail transactions.

Private banks, however, are increasingly filling this gap. They are developing frameworks that allow crypto wealth to be considered in lending decisions, often by using it as part of a broader asset-based approach. For borrowers, this creates new opportunities—but also new pitfalls if handled without specialist guidance.

The Challenge of Proof of Funds

For property transactions, the single biggest issue with crypto wealth remains proof of funds. A buyer may have millions in digital assets, but unless they can show a verifiable, compliant history of acquisition, most lenders will refuse to proceed.

Exchanges, wallets and trading platforms complicate the picture. Some buyers use decentralised wallets without third-party verification. Others have traded across multiple platforms over many years. For private banks conducting AML checks, this raises red flags.

The practical effect is that buyers with genuine wealth often struggle to evidence it in a way that satisfies lenders. Without structuring, deals stall.

Private Banks’ Evolving Approach

Unlike high street banks, private banks are more pragmatic. They recognise the growth of digital wealth and the reality that many of their clients are crypto-native. But they impose strict conditions:

• Crypto assets must usually be liquidated into fiat currency and held within a private bank before lending is approved.
• Detailed transaction histories are required, often stretching back years.
• Some banks accept crypto-derived wealth only if it is channelled through regulated exchanges.

In other words, private banks do not ignore crypto, but they demand structure. Borrowers must be prepared to document their holdings thoroughly, demonstrate compliance, and often hold assets within the bank’s custody before borrowing.

From Crypto to Lombard Lending

One of the most practical ways private banks use crypto wealth in 2025 is through Lombard lending. Here, clients pledge their fiat assets (converted from crypto) or other investment portfolios as collateral, unlocking liquidity without selling long-term holdings.

For example, an investor may liquidate a portion of crypto, place the proceeds into a custody account with the bank, and then borrow against that balance to fund a property purchase. This creates flexibility while preserving upside exposure in other parts of the portfolio.

We explored similar structures in our guide on securities backed lending in 2025. For crypto-rich clients, Lombard-style solutions often provide the cleanest path into property finance.

Tax and Regulatory Considerations

Tax adds another layer of complexity. Realising crypto gains may trigger capital gains liabilities, particularly for UK-resident borrowers. Private banks are careful to avoid being seen as facilitators of tax avoidance, so they require transparent reporting.

Meanwhile, regulators continue to scrutinise crypto-related transactions. The FCA expects enhanced due diligence on all crypto-derived wealth, meaning private banks take a conservative stance. For clients, this can be frustrating—but it also highlights the value of working with advisers who can anticipate and meet these requirements upfront.

Insurance as Part of the Package

Private banks also increasingly ask about protection when lending against crypto wealth. They want assurance that income and assets are secured beyond the volatility of digital markets. Life cover, income protection and wealth planning policies are often part of the conversation.

At Willow, we integrate these insurance solutions alongside lending. For crypto-rich borrowers, this means ensuring their mortgages are backed by robust protection strategies—whether through life insurance and estate planning, income protection or business-related cover. By combining finance and insurance, we reassure lenders and protect clients’ long-term interests.

A Real-World Example

Recently, Willow assisted an international client whose primary wealth was derived from early Bitcoin investments. They wished to acquire a prime London townhouse valued at £7 million.

Mainstream lenders refused the case outright due to the crypto source of wealth. Willow instead structured a facility with a private bank. The client liquidated a portion of their crypto holdings into fiat, deposited it into custody with the bank, and then secured a Lombard-backed mortgage at competitive terms.

At the same time, we arranged appropriate life cover and asset protection, ensuring that both the lender’s requirements and the client’s long-term planning were satisfied. Without this holistic approach, the purchase would not have been possible.

The Risks of Poor Structuring

Borrowers who attempt to fund property purchases directly from crypto wallets without guidance often face last-minute collapses. Lenders walk away when AML checks cannot be completed, leaving buyers exposed to penalties and reputational damage. Even if a deal completes, the tax and compliance implications can create expensive headaches later.

In 2025, the message is clear: crypto wealth can open doors, but only when properly structured. Private banks are willing to engage—but they require discipline, documentation and the reassurance of integrated finance and protection.

Why 2025 Is a Turning Point

The shift we are seeing in 2025 is not that private banks suddenly “like” crypto. Rather, they accept that digital wealth is here to stay, and they are building frameworks to manage it responsibly. For borrowers, this represents opportunity. With the right advice, crypto wealth can now support large-scale property acquisitions that would have been impossible even five years ago.

But the risks remain. Volatility, tax liabilities, and compliance hurdles all stand in the way. Only with experienced structuring can crypto assets be transformed into reliable, lender-ready wealth.

Frequently Asked Questions

Can crypto wealth really support property finance in the UK?
Yes — but only if handled properly. Crypto assets usually must be converted to fiat, documented with know-your-source history, and held in custody before lenders will engage.

Why do mainstream lenders reject crypto as proof of funds?
Because of challenges around traceability, AML risk, volatility, and unclear asset history. Without clear compliance trails, many lenders refuse crypto-based equity.

How do private banks approach crypto-derived lending?
They often require clients to liquidate crypto into fiat held in custody or a private bank account, present detailed transaction history, and sometimes pledge assets via Lombard or securities-backed lending.

What are the tax and regulatory complications?
Realising crypto gains may incur capital gains tax. Lenders also carry regulatory risk: they must comply with AML, so they require transparent reporting of crypto sources and may scrutinise structures more intensely.



How does Willow help turn crypto into mortgage-approved assets?
We build compliant proof-of-wealth narratives, coordinate transaction documentation, structure Lombard or asset-backed facilities, and integrate protection cover so the proposal is credible and durable.
