Many successful investors spend years building substantial investment portfolios alongside their property holdings. They may own a diversified portfolio of listed shares managed by a discretionary fund manager, hold investments through family investment companies or trusts, maintain exposure to listed investment trusts and alternative assets, while simultaneously owning residential, commercial or investment property financed through private banks or specialist lenders.

Historically, these two parts of a client's wealth have often been viewed independently.

One adviser manages the investment portfolio. Another arranges the mortgage. An accountant oversees the tax affairs. A solicitor deals with ownership structures. Each professional performs their own role exceptionally well, but the broader balance sheet is not always considered as a whole.

That approach is gradually changing.

Across private banking, wealth management and specialist property finance, there is a growing recognition that every asset should be considered within the context of the client's overall financial position. Increasingly, investment portfolios are not simply vehicles for long-term capital growth; they are also valuable sources of liquidity that can support property acquisitions, business investment and succession planning without requiring investors to dispose of assets that have taken decades to accumulate.

Against that backdrop, the Financial Conduct Authority's latest consultation on the UK Listing Rules for closed-ended investment funds may appear to be a niche regulatory update. Published on 26 June 2026, the consultation focuses on governance and shareholder protections within listed investment funds rather than lending or mortgages.

However, the proposals highlight something far broader.

The structure, governance and transparency of investment vehicles continue to matter, not only for investors themselves, but also for institutions prepared to lend against those assets.

Why The FCA Is Reviewing The Rules

The FCA's consultation follows several high-profile governance disputes involving UK-listed investment trusts earlier this year.

Much of the attention centred on activist investor Saba Capital, which accumulated significant positions in several London-listed investment trusts before seeking changes to boards and investment management arrangements. While activism has long formed part of public markets, the events prompted wider discussion around whether existing listing rules provided sufficient protection where significant shareholders might influence decisions affecting investment managers or other related parties.

Rather than introducing wholesale reform, the FCA has proposed a series of targeted amendments designed to strengthen shareholder protections, improve governance and provide greater clarity around conflicts of interest.

The regulator has described the proposals as proportionate changes intended to maintain confidence in the UK's listed investment fund sector while ensuring governance standards remain appropriate as markets evolve.

For most private investors, these changes are unlikely to alter day-to-day investment decisions.

Yet they reinforce an important principle that extends well beyond investment management.

Confidence in financial markets depends upon transparency, governance and the ability to understand exactly what an investor owns. Those same characteristics also influence how financial institutions assess risk when lending against investment assets.

Property And Investments Should Not Be Viewed In Isolation

One of the most common misconceptions among affluent investors is that their investment portfolio and property portfolio exist independently of one another.

In reality, private banks increasingly assess wealth holistically.

A client approaching a private bank to purchase a £4 million London townhouse may not simply be assessed on employment income and the property's value. Instead, the lender may consider the wider balance sheet, including investment portfolios, business interests, cash reserves, trust assets, existing borrowing and long-term wealth objectives.

This broader assessment often creates financing opportunities that simply would not exist under a conventional mortgage application.

Rather than viewing investments solely as assets intended to generate returns, sophisticated lenders increasingly recognise their potential to provide liquidity while allowing clients to maintain long-term investment strategies.

For investors who have spent decades building carefully diversified portfolios, that distinction can be extremely valuable. Selling investments to fund a property purchase is not always the most efficient solution.

Why Liquidity Matters More Than Net Worth

Being wealthy does not necessarily mean having cash readily available. In fact, many successful entrepreneurs and investors are exceptionally asset rich while remaining relatively cash constrained.

A business owner may have accumulated a £15 million investment portfolio alongside several investment properties and a successful company. On paper, their balance sheet appears exceptionally strong. However, if a significant investment opportunity arises or they decide to acquire a prime residential property, releasing several million pounds of cash is rarely straightforward.

Liquidating investments may trigger capital gains tax, disrupt carefully constructed portfolios, crystallise losses during periods of market volatility or simply force the sale of assets the investor would have preferred to retain for many years.

That is why liquidity has become one of the most valuable elements of modern wealth planning.

The objective is no longer simply accumulating wealth.

It is ensuring that wealth remains sufficiently flexible to support future opportunities without unnecessarily disrupting long-term investment strategies.

The Growing Importance Of Lombard Lending

This is where Lombard lending has become increasingly significant.

Although still less familiar than conventional mortgages, Lombard facilities have formed part of private banking for decades. Rather than requiring investors to sell qualifying investments, private banks may lend against eligible portfolios, allowing clients to unlock liquidity while retaining ownership of their underlying assets.

The facility can then be used for a wide variety of purposes.

Some clients use Lombard lending to complete a residential property purchase while waiting for another asset sale. Others utilise it to fund commercial acquisitions, business investment, tax liabilities or development projects.

Family offices frequently employ securities-backed borrowing as part of broader treasury management, ensuring capital remains available without disturbing long-term investment allocations.

The approach reflects a subtle but important shift in thinking.

Debt is no longer viewed solely as something to eliminate.

When structured appropriately, borrowing can become an efficient tool for preserving wealth.

Not Every Investment Portfolio Is Viewed Equally

Of course, lending against investments is far more complex than simply applying a percentage loan-to-value. Private banks devote considerable attention to understanding the quality of the underlying portfolio.

Highly diversified holdings invested in liquid, internationally traded companies will generally be viewed differently from concentrated positions in a single company or specialist investments where pricing may be less transparent.

Similarly, portfolios containing investment trusts, infrastructure funds or private market exposure require careful assessment to determine how readily assets could be realised if market conditions changed.

This is one reason why governance matters.

The FCA's consultation is fundamentally concerned with ensuring investors continue to have confidence in the governance arrangements underpinning listed closed-ended investment funds.

Although the proposals are not designed to influence lending decisions directly, stronger governance supports confidence in the broader investment environment.

For lenders assessing investment portfolios as potential security, confidence and transparency remain valuable characteristics.

They reduce uncertainty.

Investment Structure Has Become Increasingly Important

How assets are owned can be almost as important as what assets are owned. High-net-worth clients increasingly hold investments through family investment companies, trusts, offshore structures or corporate entities.

These arrangements may deliver significant tax planning or succession planning benefits, but they can also influence how easily assets can be used within financing strategies. Ownership structures affect legal documentation, security arrangements, valuation processes and lender due diligence.

Private banks therefore spend considerable time understanding not simply the value of investments but also the legal framework surrounding them.

This is one reason why specialist advisers increasingly work alongside accountants, solicitors and wealth managers when structuring larger transactions. The objective is not merely obtaining finance.

It is ensuring every element of the client's balance sheet works together efficiently.

Property Purchases No Longer Need To Mean Selling Investments

Consider an entrepreneur who has accumulated a substantial investment portfolio over thirty years.

Their investments continue generating attractive long-term returns, and their advisers believe maintaining exposure remains sensible despite short-term market fluctuations. The same client identifies an exceptional opportunity to acquire a prime London property.

Under a traditional approach, they might simply sell several million pounds of investments to fund the purchase.

However, doing so could interrupt their investment strategy, generate unnecessary tax liabilities and remove exposure to future market growth. An alternative approach may involve using part of that investment portfolio as security for borrowing while arranging the property finance separately.

The investments remain invested.

The property acquisition proceeds.

The investor preserves long-term market exposure while achieving immediate liquidity. Every client's circumstances differ, and no solution suits everyone.

Nevertheless, this illustrates why sophisticated borrowing has become an increasingly important component of wealth management.

Family Offices Are Taking A Broader View Of Capital

Global family offices have spent recent years placing increasing emphasis on capital efficiency rather than simply asset accumulation. Reports from leading private banks consistently show that many wealthy families now focus on ensuring every part of their balance sheet contributes towards wider financial objectives.

• That may involve investment portfolios supporting business expansion.
• Commercial property generating income that funds new acquisitions.
• Private banking facilities providing short-term liquidity while preserving long-term investments.
• Or residential property purchases structured alongside broader wealth planning strategies.

Rather than asking whether borrowing is necessary, sophisticated investors increasingly ask whether borrowing allows capital to remain deployed more efficiently elsewhere.

It is a subtle distinction, but one that continues to shape modern private banking.

Why This Matters For Property Investors

For specialist mortgage advisers, this evolution has important implications. Property finance is becoming increasingly integrated with wealth planning.

Clients no longer approach advisers simply seeking the lowest interest rate. They want to understand how borrowing fits within their wider financial position.

• Should investments be sold?
• Could securities-backed lending provide temporary liquidity?
• Would private banking facilities preserve flexibility?
• Is there a more efficient way to structure borrowing across multiple assets?

These conversations extend well beyond conventional mortgage advice.

They require advisers capable of understanding both property finance and broader wealth structures.

Looking Beyond The FCA Consultation

The FCA's consultation is, at its heart, a governance exercise. It seeks to strengthen confidence in the UK's listed closed-ended investment fund sector by refining listing rules and ensuring appropriate protections remain in place for investors.

Yet its significance extends beyond regulation alone, it reminds us that investment structures matter.

Transparency matters.

Governance matters.

And increasingly, these characteristics influence not only investment decisions but also access to sophisticated borrowing solutions.

As private banking, wealth management and specialist property finance continue to converge, successful investors are likely to benefit from advisers capable of viewing the entire balance sheet rather than focusing on individual assets in isolation.

The future of high-net-worth lending is unlikely to revolve solely around property values or income multiples.

Instead, it will increasingly reflect the quality, structure and flexibility of a client's overall wealth.

For many investors, their investment portfolio may prove to be far more than a source of long-term returns.



It may become one of the most valuable financial tools available when the next property opportunity arises.
