The Bank of England's latest Financial Stability Report arrives at an important moment for high-net-worth investors. While much of the media attention has focused on interest rates and the resilience of the banking sector, the report also highlights several areas that are highly relevant to anyone who borrows against investment portfolios or uses leverage as part of their wider wealth strategy.

Among the themes identified are elevated valuations across some asset classes, increasing leverage within equity markets, continued expansion of private credit, and the potential for periods of reduced liquidity should market conditions deteriorate. None of these are presented as immediate causes for alarm. Instead, they serve as a reminder that leverage remains a powerful financial tool, but one that requires careful structuring, ongoing monitoring and an understanding of how different market environments can affect borrowing facilities.

For private banking clients, family offices and sophisticated investors, these observations reinforce the importance of treating securities-backed lending as part of a broader wealth management strategy rather than simply a source of liquidity.

The Financial Stability Report In Context

Published twice each year, the Bank of England's Financial Stability Report examines risks that could threaten the stability of the UK financial system. Unlike monetary policy announcements, which focus on inflation and interest rates, the Financial Stability Report considers the resilience of banks, financial markets, investment funds, private credit, leverage and global capital markets.

The July 2026 edition reflects a financial system that has remained broadly resilient despite geopolitical uncertainty, elevated government debt, changing interest rate expectations and periods of market volatility.

However, the report also identifies several structural vulnerabilities that deserve attention.

These include:

• continued high valuations across certain financial assets;
• increasing use of leverage by market participants;
• rapid growth within private credit markets;
• reduced liquidity during periods of market stress; and
• ongoing risks surrounding sovereign debt markets and government bond yields.

For most retail borrowers these themes may seem distant. For investors with significant investment portfolios or those borrowing against financial assets, they are directly relevant.

Borrowing Against Wealth Has Become Increasingly Mainstream

One of the biggest changes in private banking over the past decade has been the growing use of asset-backed lending.

Rather than selling investment portfolios to raise cash, many affluent clients now borrow against their assets.

Known as Lombard lending, securities-backed lending or portfolio finance, these facilities allow borrowers to unlock liquidity while retaining ownership of their investments.

This approach has become increasingly popular among entrepreneurs, family offices, business owners and internationally mobile clients because it avoids triggering capital gains tax events, preserves long-term investment strategies and provides fast access to capital.

Typical uses include:

Purchasing residential or commercial property, funding tax liabilities, supporting business acquisitions, financing private investments, providing working capital, making gifts to family members or bridging liquidity while other assets are realised.

When structured correctly, securities-backed lending can be significantly more cost-effective than unsecured borrowing and often considerably faster than arranging traditional property finance.

Yet its success depends on understanding how collateral values behave during changing market conditions.

Collateral Is Not Static

One of the most important messages within the Financial Stability Report is that financial asset prices can move rapidly when market sentiment changes.

During periods of strong market performance, it is easy to assume investment portfolios will continue appreciating indefinitely.

History demonstrates otherwise.

Equities, corporate bonds, investment funds and even diversified portfolios can all experience periods of volatility.

For borrowers using those assets as security, changes in portfolio value directly influence borrowing capacity.

Unlike residential mortgages, where property valuations are reviewed relatively infrequently, securities-backed lending facilities are monitored continuously.

If collateral values decline sufficiently, lenders may require additional assets to be pledged, partial repayment of the facility, or a reduction in borrowing levels.

These are commonly referred to as margin calls.

Private banks design their lending policies specifically to minimise the likelihood of this occurring, but understanding the possibility remains fundamental to prudent borrowing.

Why Loan-To-Value Matters More Than Interest Rates

Many borrowers naturally focus on pricing.

While interest costs are important, experienced private bankers often pay greater attention to loan-to-value ratios.

The lower the initial leverage, the greater the protection against future market movements.

For example, a borrower utilising only 20% or 30% of available borrowing capacity has significantly greater resilience than someone borrowing close to the maximum facility available.

Conservative leverage creates flexibility.

It reduces the likelihood of margin calls, preserves liquidity during periods of volatility and allows investment strategies to continue without forced asset sales.

This disciplined approach becomes particularly valuable during periods of market uncertainty—the very scenario highlighted within the Bank of England's latest assessment.

Liquidity Is Different From Value

One theme receiving increasing attention from regulators is market liquidity.

Liquidity refers not to the value of an asset but to how easily it can be bought or sold without materially affecting its price.

Under normal market conditions, listed equities and government bonds are generally highly liquid.

However, during periods of financial stress, even traditionally liquid markets can become significantly more difficult to trade efficiently.

The Financial Stability Report notes that strains within sovereign debt markets and parts of the private credit sector could amplify volatility during periods of market disruption.

For borrowers, this distinction matters.

A portfolio may retain substantial long-term value while becoming temporarily more difficult to realise quickly.

Private banks therefore assess not only the value of collateral but also its liquidity profile when determining lending limits.

Cash, government bonds and blue-chip listed equities generally attract higher advance rates than concentrated shareholdings, private equity interests or less liquid alternative investments.

Private Credit Continues To Grow

Another significant theme within the report is the continued expansion of private credit.

Private credit has grown rapidly as institutional investors seek higher yields while traditional banks have become more selective in certain lending sectors.

The sector now finances everything from corporate acquisitions and infrastructure projects to commercial real estate and development finance.

This expansion has created valuable funding opportunities for many businesses and investors.

However, regulators also recognise that private credit structures can involve greater complexity, reduced transparency and different liquidity characteristics compared with traditional bank lending.

For borrowers considering bespoke funding solutions, this reinforces the importance of understanding not only pricing but also covenant structures, repayment obligations, security arrangements and exit strategies.

The cheapest funding is not always the most appropriate funding.

Securities-Backed Lending Requires Ongoing Management

One misconception surrounding Lombard lending is that it operates like a conventional mortgage.

In reality, it is a dynamic facility.

• Investment portfolios evolve.
• Markets move daily.
• Client objectives change.
• Borrowing requirements fluctuate.

Private banks therefore expect facilities to be reviewed regularly.

This may involve adjusting borrowing levels, adding collateral, diversifying investments or refinancing facilities as circumstances change.

Sophisticated borrowers increasingly treat securities-backed lending as an active component of wealth management rather than a one-off transaction.

The relationship between investment adviser, wealth manager and lending specialist becomes central to achieving this.

Diversification Reduces Concentration Risk

The Bank of England's observations regarding elevated valuations also highlight another important principle.

Concentration risk matters.

Many entrepreneurs accumulate significant wealth through ownership of a single business or concentrated shareholding.

While this can create substantial wealth, it can also expose borrowers to greater collateral volatility.

Private banks often apply more conservative lending parameters where portfolios lack diversification.

By contrast, diversified portfolios across multiple sectors, geographies and asset classes generally provide more stable collateral characteristics.

This benefits both borrower and lender.

Diversification is therefore not simply an investment principle—it is often a financing principle as well.

Liquidity Planning Should Begin Before It Is Needed

One of the strongest themes emerging from the Financial Stability Report is the importance of resilience.

For high-net-worth individuals, resilience frequently comes down to liquidity planning.

Many successful clients arrange borrowing facilities before they require them.

Having pre-approved access to liquidity allows investment decisions to be made from a position of strength rather than necessity.

It also reduces the likelihood of selling investments during periods of market weakness simply to generate cash.

Whether funding a property purchase, meeting a tax liability, supporting a business opportunity or financing succession planning, access to flexible liquidity often proves more valuable than reacting after circumstances have changed.

The Role Of Specialist Advice

The modern private banking market offers a wide range of financing solutions.

These include Lombard lending, securities-backed revolving credit facilities, investment portfolio finance, bespoke private bank mortgages, commercial facilities, structured lending and hybrid arrangements combining multiple asset classes.

Each lender assesses collateral differently.

Advance rates vary depending on asset type, jurisdiction, diversification, concentration and overall client relationship.

This means that selecting the right lender involves considerably more than comparing headline interest rates.

Borrowers should understand how facilities perform during periods of volatility, what collateral monitoring arrangements exist, how margin calls are managed and whether additional flexibility is available if market conditions change.

Working with advisers who understand both investment portfolios and specialist lending can help ensure facilities are structured with appropriate resilience from the outset.

Looking Beyond The Headlines

The Bank of England's July 2026 Financial Stability Report should not be interpreted as a warning against leverage. Well-structured borrowing remains an effective tool for enhancing liquidity, preserving investment strategies and supporting long-term wealth planning.

Instead, the report reinforces a broader message that experienced private bankers have long understood: leverage works best when combined with prudent loan-to-value ratios, diversified collateral, robust liquidity planning and regular review.

For affluent borrowers, the objective is not simply to maximise borrowing capacity. It is to create financing arrangements that remain effective across changing market conditions, allowing opportunities to be seized without compromising long-term financial security.



As financial markets continue to evolve, understanding the relationship between collateral, leverage and liquidity will become an increasingly valuable part of wealth management. Those who approach securities-backed borrowing strategically are likely to be better positioned to navigate both periods of market stability and episodes of heightened volatility, while continuing to put their capital to work efficiently over the long term.
