When high-net-worth individuals borrow against an investment portfolio, the focus often falls on the amount that can be borrowed, the interest rate available or how quickly funds can be released.

Far less attention is given to a more fundamental question: does the borrower fully understand the investments securing the loan?

According to the Financial Conduct Authority (FCA), that question is becoming increasingly important.

In findings published this week, the regulator criticised the investment industry after reviewing consumer disclosure documents and concluding that only 6% were written in plain English. The vast majority relied on technical terminology, lengthy explanations and complex language that many investors would struggle to understand, despite the documents being intended to help consumers make informed financial decisions.

The FCA's concerns are part of its wider Consumer Duty initiative, which places greater responsibility on financial firms to ensure clients genuinely understand the products they purchase rather than simply receiving large volumes of regulatory paperwork.

Although the review focused on investment disclosure documents, the implications extend well beyond investment advice. They also have important consequences for anyone considering borrowing against an investment portfolio through a Lombard lending or portfolio-backed finance facility.

Borrowing Against Investments Requires More Than A Valuable Portfolio

Portfolio-backed lending has become an increasingly popular source of liquidity among high-net-worth individuals, entrepreneurs and sophisticated investors.

Rather than selling investments to raise capital, borrowers use eligible portfolios as security for a lending facility. The approach can provide access to substantial liquidity while allowing long-term investment strategies to remain largely intact.

It is a strategy commonly used to fund property purchases, refinance existing borrowing, provide business capital or create liquidity without triggering unnecessary investment sales.

However, unlike a conventional mortgage, the quality of the collateral extends far beyond its monetary value.

Private banks and specialist lenders undertake detailed analysis of the underlying investments before determining how much they are prepared to lend. Liquidity, diversification, concentration risk, historic volatility and asset quality all influence both the available loan-to-value ratio and the ongoing management of the facility.

A portfolio valued at several million pounds may therefore support significantly different borrowing levels depending on how those investments are structured.

This is precisely why the FCA's findings matter.

If investors find it difficult to understand the products they own, they may also struggle to appreciate how those investments behave once they become collateral for borrowing.

Understanding The Risks Before They Matter

Investment values fluctuate. That is an accepted characteristic of financial markets.

When investments are held purely for long-term growth, temporary market movements may have little immediate impact on an investor's overall strategy.

Borrowing introduces another dimension.

Because the investment portfolio secures the lending facility, lenders continue to monitor its value throughout the life of the loan. Should markets experience significant volatility, the available borrowing capacity may change depending on the terms of the agreement. In some circumstances, additional collateral or partial repayment may be required to maintain the agreed lending ratio.

These arrangements are entirely normal within portfolio-backed lending and are discussed openly during the structuring process by experienced private banks.

The issue identified by the FCA is that clients cannot properly evaluate these risks if the underlying investment information itself is unnecessarily difficult to understand.

Complex disclosure documents may satisfy regulatory requirements, but they do not necessarily help investors appreciate how their portfolios could perform during changing market conditions or how those movements might influence a borrowing facility.

Consumer Duty Is Raising The Standard

The FCA's review forms part of a broader programme aimed at improving communication across financial services.

Rather than measuring compliance by the volume of documentation firms produce, the regulator is increasingly asking a simpler question: would a reasonable consumer genuinely understand what they are buying?

That represents a significant shift.

For many years, financial disclosure has often prioritised legal completeness over genuine understanding. Documents became longer, more technical and increasingly reliant on industry terminology that offered limited practical value to many investors.

The FCA is now encouraging firms to communicate in a way that allows consumers to understand product features, costs and risks before making financial decisions.

Within private banking, this principle already sits at the heart of many lending relationships.

Experienced lenders rarely view a Lombard facility as a standalone transaction. Instead, they assess how the borrowing fits within a client's wider wealth strategy, considering investment objectives, liquidity requirements, tax planning, succession planning and future financing needs.

The most successful facilities are built on transparency rather than complexity.

Why Wealth Managers And Lending Advisers Must Work Together

Portfolio-backed lending is one of the clearest examples of where investment advice and lending advice overlap.

A discretionary fund manager may be responsible for constructing and managing the investment portfolio, while a private bank assesses its suitability as collateral. Mortgage specialists, tax advisers and solicitors often contribute to the overall structure, ensuring the borrowing complements the client's broader financial objectives.

This collaborative approach becomes considerably more effective when every adviser, and more importantly every client, has a clear understanding of both the investments involved and the lending arrangements being established.

The FCA's latest findings reinforce the importance of that transparency.

Clear communication not only improves regulatory outcomes but also helps borrowers make more informed decisions about how much to borrow, which assets to pledge as collateral and how those arrangements may perform throughout different market cycles.

The Bottom Line

The FCA's criticism of investment disclosure documents is about far more than simplifying financial language.

It reflects a wider expectation that consumers should genuinely understand the financial products they own before making significant decisions.

For investors considering portfolio-backed lending, that principle is especially important.

Borrowing against an investment portfolio can be an exceptionally effective way to release liquidity while preserving long-term investment strategies. However, the strength of the arrangement depends not only on the value of the assets, but also on the borrower's understanding of how those assets behave, how lenders assess them and how the lending facility operates under changing market conditions.



As portfolio-backed finance continues to grow within private banking and specialist lending, clarity is becoming just as valuable as capital itself.
