W1M Embeds Lombard Lending Without Moving Client Assets
Market Intelligence · 11 September 2026

Investment-Backed Lending Is Moving Inside Wealth Management

W1M, which manages £28.7bn, has integrated Firenze's portfolio-backed lending into its client proposition without requiring eligible borrowers to move their existing custody arrangements. The development illustrates how Lombard lending is moving beyond the traditional private-bank model.

£28.7bn Wealth Manager W1M Embeds Lombard Lending Without Moving Client Assets

W1M has integrated Firenze's portfolio-backed lending capability into its wealth-management proposition while allowing eligible clients to maintain their existing custody arrangements. It is another sign that investment-backed credit is becoming part of mainstream wealth-management infrastructure rather than remaining solely within private banks.

A wealth manager responsible for £28.7bn of client assets has embedded portfolio-backed lending into its proposition without requiring eligible clients to transfer their investments to the lender. The W1M and Firenze partnership is a relatively simple announcement, but the operating model behind it represents a more significant change in how high-net-worth clients can access liquidity.

Firenze announced the partnership with W1M on 8 September, with further industry coverage this week. Eligible W1M clients can access lending secured against their investment portfolios while retaining their existing custody arrangements.

SEI, which already provides custody and wealth-platform capabilities to W1M, supplies the data connectivity and operational controls supporting the arrangement. Firenze's lending technology is therefore being integrated into an existing wealth-management infrastructure rather than requiring the client to establish a conventional private-bank custody relationship solely to access credit.

That distinction is strategically important. Lombard lending has traditionally been strongly associated with private banks, where the ability to borrow against an investment portfolio can be linked to moving or maintaining substantial assets with the bank. The newer model increasingly separates custody from credit.

What Has W1M Announced?

W1M, an international wealth and investment manager with £28.7bn of assets under management, has partnered with Firenze to provide eligible clients with access to portfolio-backed lending.

The solution is integrated with W1M's operating processes and allows eligible borrowers to maintain their existing custody arrangements rather than moving the investment portfolio to the lender.

The arrangement is enabled through SEI's custody and wealth-platform capabilities, which provide the data connectivity and operational controls supporting access to Firenze's lending infrastructure.

The Important Change Is Not Simply Another Lombard Provider

Lombard lending itself is not new. Wealthy individuals have borrowed against investment portfolios for generations, and private banks routinely include securities-backed credit within wider banking relationships.

What is changing is the route through which clients can access it.

Firenze explicitly positions its proposition around allowing wealth managers and advisers to add lending without clients moving custody or meeting the minimum asset requirements typically associated with private banking.

The W1M partnership shows what that looks like in practice at material scale. Portfolio-backed credit can sit inside an existing wealth-management relationship even though the investment manager itself is not becoming the lender and the client's assets do not have to migrate into a new private-bank ecosystem.

The Traditional Model Is Being Unbundled

The historical private-bank proposition could effectively be: place the assets with us and we can lend against them.

The newer infrastructure model is increasingly capable of saying: keep the existing investment relationship and add lending alongside it.

Why Custody Matters So Much to Wealth Managers

For a wealth manager, moving client assets elsewhere simply to obtain credit can create an obvious commercial tension.

Imagine a client has £3m invested with an established discretionary manager and needs £750,000 for a property purchase. A private bank may be willing to provide the liquidity, but only within a wider relationship that involves transferring some or all of the investment portfolio to the bank.

That can be perfectly acceptable where the client already wants a new banking or investment relationship. It is considerably less attractive where they are satisfied with the existing investment manager and the only requirement is temporary liquidity.

The ability to add portfolio-backed credit while leaving custody intact removes much of that friction. The wealth manager can potentially retain the investment relationship while the client accesses debt against eligible securities.

This Makes Lending Part of the Wealth-Management Service

W1M's chief operating officer, Michael Allen, described borrowing requirements as something that can arise alongside clients' investment and wealth-management needs.

That is an important conceptual shift.

A HNW client's balance sheet contains both assets and liabilities. Yet wealth management has historically concentrated primarily on investments, planning and preservation of assets, while property mortgages and other borrowing can sit elsewhere with little coordination.

Embedding lending into the wealth-management process starts to close that gap.

A client may want liquidity to buy property, invest in a business, meet a tax liability, support family members or bridge the timing between two major financial events. Selling investments is one solution. Borrowing against them can be another.

A £3m Portfolio Can Now Support Liquidity Without Necessarily Moving

Consider a client with a £3m diversified investment portfolio already managed by a wealth firm. They need £750,000 to complete on a property before another asset is sold six months later.

Historically, the obvious routes might include selling investments, arranging a mortgage or bridge, or establishing a private-bank relationship capable of providing securities-backed credit.

The W1M model demonstrates another route: keep the investment portfolio within the existing custody and management arrangement while introducing a specialist credit provider alongside it.

For the client, that can preserve the underlying investment strategy. For the wealth manager, it reduces the risk that a liquidity requirement causes assets to move to another institution purely because that institution controls the credit capability.

But Easier Access Does Not Mean Lombard Lending Is Always the Right Answer

The growth of embedded lending creates an important second question.

If Lombard facilities become easier for wealth managers to provide, there is a risk that every client liquidity requirement starts to look like a portfolio-backed lending problem.

It is not.

A client buying a £2m property might be able to borrow against investments, against the property itself or against another property already owned. They may also qualify for a private-bank mortgage, a conventional large residential mortgage or, for a short-duration requirement, bridging finance.

The appropriate capital source depends on cost, duration, collateral, flexibility and risk rather than simply which facility can be produced most conveniently.

Property-Backed and Portfolio-Backed Debt Behave Differently

Portfolio-Backed Lending Property-Backed Lending
Secured against eligible investment assets. Secured principally against property.
Borrowing capacity can change if portfolio values or asset eligibility change. Property values typically move less frequently, although valuations and LTV still matter.
Can provide liquidity without selling investments. Can preserve the investment portfolio as unencumbered financial capital.
May be highly flexible for short or medium-term liquidity. Can be more appropriate for long-duration property borrowing.
Margin-call and collateral-maintenance risk can apply. Mortgage covenants and repayment obligations apply, but daily investment-market volatility does not normally alter collateral requirements.
Suitable collateral composition is fundamental. Property type, value, borrower affordability and repayment strategy are fundamental.

Margin Risk Is the Key Difference Borrowers Need to Understand

The convenience of a Lombard facility should not obscure the risk attached to its collateral.

Firenze states that borrowing may be available up to 50% loan-to-value against eligible investment portfolios. The amount available in a real case depends on what the client owns because different securities can attract different lending values and concentration limits.

If investment markets fall sharply, the value supporting the facility can decline. Depending on the loan agreement, the borrower may then need to provide additional collateral, reduce the borrowing or face assets being sold to restore the required margin.

That makes a Lombard facility fundamentally different from a normal residential mortgage, even where both are being used to provide the same £500,000 or £1m of cash.

The right comparison therefore cannot stop at interest cost.

A Concentrated Portfolio Can Produce a Very Different Result

A client with £5m spread across diversified liquid securities can present very differently from a founder whose £5m portfolio is dominated by one listed company.

Both clients may describe themselves as having £5m of investments. They may not have anything close to the same portfolio-backed borrowing capacity.

Lenders can apply different advance rates to different securities and may reduce the lending value of concentrated or more volatile positions. Assets that appear significant on a personal balance sheet may therefore contribute less collateral value than expected.

This is one reason why a wider lending comparison can remain valuable even as access to Lombard credit becomes easier. A property mortgage could potentially provide more stable or larger borrowing where the investment portfolio itself is unsuitable security.

Multiple Custodians Create Another Layer of Complexity

Ultra-high-net-worth families frequently hold investments across more than one bank, wealth manager or custody platform.

A client may therefore have £2m managed by one DFM, £3m at a private bank and another £2m in separately managed securities.

No single portfolio may provide the desired borrowing capacity even though the overall balance sheet is substantial.

Cross-custody lending models are strategically interesting because they create the possibility of separating the credit provider from the institution physically holding or managing the investments. The detail of what a particular lender can accept remains case-specific, but the direction of travel is clear: custody and lending do not necessarily have to sit inside the same institution.

What Should Be Compared Before Using the Portfolio?

Effective Cost Interest margin, reference rate, arrangement costs and the likely duration of borrowing need to be compared with alternative debt.
Eligible Collateral The headline portfolio value is less important than the lending value assigned to the actual assets within it.
Concentration Single-stock positions and more volatile securities can materially reduce lending capacity.
Custody Requirements Establish whether investments must move or whether the lender can work with the client's existing custody structure.
Margin Exposure The borrower needs to understand what happens if the portfolio falls sufficiently to breach agreed collateral thresholds.
Repayment Strategy The source and expected timing of repayment should fit the facility rather than relying indefinitely on investment values remaining favourable.

The Property Itself May Be the Cheaper Source of Capital

A client requiring cash for a property transaction can sometimes become overly focused on avoiding a mortgage.

There may be good reasons to use the investment portfolio, particularly where borrowing is short term and the client does not want to sell securities. But if the property can support conventional debt at a lower overall cost and over a more suitable term, there is little value in using a Lombard facility simply because it is available.

The reverse is also true. A client who intends to repay within six months may find a long-term property mortgage cumbersome compared with a flexible portfolio-backed facility, particularly once valuation, legal work and mortgage early repayment charges are considered.

The important question is which asset should carry the borrowing for the period the capital is actually required.

The Liquidity Requirement Comes First. The Product Comes Second.

A client needs £1m. That does not automatically mean they need a £1m Lombard facility, a £1m mortgage or a £1m bridge.

The finance decision should begin with the duration, repayment source, available collateral and wider balance sheet before deciding which asset should be used to create the liquidity.

This Is Why Embedded Credit Changes the Role of the Wealth Manager

As lending becomes easier to integrate, wealth managers increasingly have to consider client liabilities alongside investment objectives.

That can improve client service materially. An adviser who knows that the client is about to liquidate £750,000 of a long-term portfolio for a temporary property requirement can raise the possibility of borrowing before the sale changes the investment strategy.

Equally, the existence of an embedded credit facility should not create an assumption that maintaining the portfolio at all costs is always preferable. Borrowing carries a cost and creates risk, while selling assets can have investment and tax consequences that should be assessed by the relevant advisers.

The objective is to identify the capital structure that best supports what the client is actually trying to achieve.

The Private Bank Still Has Important Advantages

The emergence of embedded Lombard platforms does not make private banks redundant.

A private bank may be able to consider a client's entire financial relationship, provide larger facilities, lend in several currencies, combine property and securities-backed credit, accommodate international structures or provide credit against assets that a more standardised platform will not accept.

For a family requiring £10m or £20m of complex credit rather than £500,000 of straightforward portfolio liquidity, that bespoke underwriting capability can be extremely valuable.

The point is not that embedded lending replaces private banking. It creates another route that needs to be compared with it.

Simple Access to One Provider Is Becoming Less Differentiated

This development has an important implication for the wider advisory market.

If a major wealth manager can embed a provider such as Firenze directly, access to that lender alone becomes less of a specialist proposition.

The same is likely to happen elsewhere as technology and custody connectivity allow more wealth firms and platforms to add credit without building an internal lending business.

The value of independent finance advice therefore moves away from simply knowing one lender that will advance money against a portfolio.

It moves towards identifying whether the portfolio should be used as collateral at all, which lender provides the appropriate advance against the actual assets involved, and whether a mortgage, private-bank facility, bridge or blended structure produces a better outcome.

For Wealth Managers, the Question Becomes Broader Than Lombard Lending

A wealth manager may encounter a client who needs £1.5m for a London property purchase, £500,000 for a business requirement or temporary liquidity while another asset is sold.

The investment portfolio is one possible source of collateral. It may not be the only one.

The same client may own substantial unencumbered property, qualify for a conventional mortgage, have another property that can support a second charge or be able to access a private-bank facility using the wider relationship.

A wealth manager does not necessarily need an internal specialist capable of comparing every one of those lending markets. It does need a process for recognising that the liability problem extends beyond the product embedded in its platform.

Property Purchases Are a Natural Test Case

Property transactions demonstrate the distinction particularly clearly because the client often has several plausible ways to create the required liquidity.

Consider a HNW investor buying a £2.5m property with £1.5m available in cash and investments but wanting to preserve most of their portfolio.

One option is to borrow £1m against the investments. Another is to arrange a £1m mortgage on the new property. The client could also use short-term portfolio-backed credit to complete quickly and subsequently replace it with longer-term property finance.

Each structure produces a different balance between transaction speed, collateral risk, long-term interest cost and investment liquidity.

No single product category can answer that question in isolation.

Tax and Estate Liquidity Can Produce the Same Choice

The same comparison arises where a family needs liquidity around tax, estate administration or succession.

An eligible investment portfolio may provide rapid borrowing capacity. Property could also support finance, while the family may have other cash resources or assets that can be realised.

Tax and estate strategy belong with the client's professional advisers. The financing role is to establish what forms of liquidity are actually available once those advisers have determined the amount required and the intended repayment strategy.

Using a Lombard facility purely because the wealth manager can access one would be no more appropriate than automatically using a bridge simply because the family owns property.

A Wealth-Manager Liquidity Review Should Start With the Balance Sheet

Question Why It Matters
How much liquidity is actually required? Avoids unnecessarily encumbering more investments or property than the transaction requires.
For how long? A six-month funding requirement can justify a very different structure from ten-year borrowing.
What is the repayment source? Property sale, business proceeds, bonus, investment maturity or long-term income can each point towards different debt.
Which assets are available as security? Investment portfolios and property can carry very different borrowing costs and risks.
How concentrated is the portfolio? Concentration can reduce lending value and increase collateral volatility.
Does custody need to move? Moving assets may alter investment arrangements and the economics of the wider relationship.
What alternatives exist? Lombard, mortgage, private-bank, bridging and blended structures should be considered where relevant.

W1M's Scale Makes the Partnership More Significant

W1M is not a niche investment boutique adding an experimental lending service. The firm reports £28.7bn of assets under management, five global offices and approximately 440 employees.

It serves high-net-worth and ultra-high-net-worth individuals and families as well as charities, institutions and financial advisers. Its capabilities also include cross-border planning and investment management for internationally complex clients.

Embedding portfolio-backed credit into a business of that scale is therefore a useful indicator of where the wealth-management market is heading.

The client increasingly expects the wealth relationship to recognise that investments are only one part of their financial life. Credit, liquidity and property requirements sit alongside them.

SEI's Role Shows Why This Is Also a Technology Story

One reason this type of model is becoming possible is the infrastructure linking lender, adviser and custodian.

Firenze says SEI's custody and wealth-platform capabilities provide the data connectivity and operational controls supporting the W1M solution.

That matters because a lender advancing money against a portfolio needs reliable information about the collateral and controls around the assets supporting the facility.

Historically, keeping custody and credit within the same private bank solved that problem structurally. Technology is increasingly allowing the lending relationship to sit alongside third-party custody instead.

That is the deeper development behind the W1M announcement: the operational connection between wealth manager, custodian and lender is becoming infrastructure rather than requiring all three roles to be performed by one bank.

How Willow Private Finance Can Help

Willow Private Finance works with HNW clients, wealth managers and family offices where a liquidity requirement can potentially be solved through more than one source of capital.

A portfolio-backed facility may be highly appropriate, particularly where a client needs short-term liquidity and wants to avoid selling investments. In other cases, borrowing against property, using another securities-backed provider, arranging private-bank credit or combining more than one source of debt can produce a different outcome.

Our role is to compare those routes rather than assume the investment portfolio should automatically carry the borrowing because a Lombard facility is readily available.

For a wealth manager, that allows the investment relationship to remain focused on managing the client's assets while Willow examines the liability side: facility size, collateral, duration, repayment strategy, property alternatives and the wider lender market.

Need Liquidity Without Automatically Selling or Moving the Portfolio?

The W1M and Firenze partnership shows how quickly portfolio-backed lending is becoming integrated into modern wealth management. But access to a Lombard facility is only the first question.

Willow Private Finance can compare investment-backed lending with private-bank and property-secured alternatives, helping establish which asset should support the borrowing and whether the proposed facility remains competitive against the wider market.

Frequently Asked Questions

Key questions following W1M's integration of Firenze portfolio-backed lending into its wealth-management proposition.

What has W1M added for its wealth-management clients?

W1M has partnered with Firenze to provide eligible clients with access to portfolio-backed lending secured against investment portfolios. The arrangement is integrated into W1M's operating processes and allows existing custody arrangements to remain in place.

Do W1M clients have to move their investments to Firenze to obtain the lending?

The partnership announcement states that eligible clients can maintain their existing custody arrangements. Firenze's wider proposition is specifically designed to provide investment-backed lending without requiring clients to move custody to a traditional private bank.

Is Lombard lending always better than borrowing against property?

No. Lombard lending and property-backed borrowing use different collateral and carry different risks. Portfolio-backed credit can provide flexible liquidity without selling investments, while property-secured lending may offer different pricing, terms and collateral characteristics. The appropriate structure depends on the client's circumstances.

What risks should be considered with portfolio-backed lending?

Investment values can fall, which may reduce borrowing headroom or trigger requirements for additional collateral or repayment depending on the facility. Portfolio concentration, eligible securities, advance rates, currency and the intended repayment source should all be considered before proceeding.

Why might a wealth-management client still compare several lending routes?

An embedded Lombard facility can be convenient, but the client may also have access to other securities-backed lenders, private banks, large-loan mortgages, bridging or other property-secured finance. Comparing the available capital sources can establish which collateral, cost and structure best fit the requirement.

Your Client Needs Liquidity. Which Asset Should Provide It?

Easier access to portfolio-backed credit is valuable, but the investment portfolio is not automatically the best place to put every borrowing requirement.

Willow Private Finance can compare Lombard and securities-backed facilities with private-bank, large-loan mortgage, bridging and other property-secured options, while leaving the client's investment-management relationship intact.

For wealth managers and family offices, this creates an independent debt route for liquidity requirements that do not fit neatly into a single embedded lending product.

The objective is not simply to find a lender willing to advance against the portfolio. It is to establish which capital source produces the right combination of cost, collateral, duration and risk.

Important Notice

This article is provided for general information only and does not constitute mortgage, investment, tax, legal or personalised financial advice.

Firenze announced its partnership with W1M on 8 September 2026. The arrangement provides eligible W1M clients with access to portfolio-backed lending and allows existing custody arrangements to remain in place. All lending remains subject to eligibility, underwriting and credit approval.

References to maximum loan-to-value levels reflect Firenze's currently published general proposition and should not be interpreted as a guaranteed borrowing level for any individual client. Actual lending capacity depends on the composition, concentration, liquidity and eligibility of the investment portfolio and the lender's underwriting.

Lombard and securities-backed lending involves risks materially different from conventional property-secured borrowing. Investment-market movements may affect the value of collateral and can result in requirements for additional collateral, repayment or asset sales depending on facility terms.

Investment management and decisions to retain or sell investments should be considered with appropriately qualified investment and tax advisers. Willow Private Finance's role is limited to relevant lending and property-finance requirements and does not include investment management or investment advice.

Property and securities-backed lending products, criteria, pricing and availability can change. Borrowers should obtain advice based on their individual circumstances before entering into a credit agreement.
