How WealthOptic helps Private Bankers compare funding options for HNW clients

A private banker was working with a 45-year-old senior technology executive whose financial affairs had become increasingly complex.

The client was working towards an early retirement in the sun. His compensation package had included substantial equity awards over more than a decade, resulting in a significant concentration of wealth in his employer’s stock.

His balance sheet looked roughly as follows:

Employer stock: £3.5 million
Discretionary managed portfolio: £4.5 million
A UK home worth £1.5 million
Existing mortgage debt: £0
Annual compensation: £550,000+

The client and his family had identified a luxury property in Portugal worth approximately £2.5 million. After accounting for available cash reserves, he needed access to around £2.25 million in liquidity.

At first glance, the solution appeared simple: sell a portion of the concentrated stock holding and use the proceeds to purchase the property.

However, his private banker recognised that the decision was far more complex.

The Challenge

The executive’s employer shares had appreciated significantly over the years.

Selling enough stock to generate £2.25 million after tax would trigger a substantial capital gains tax liability. Furthermore, the client was considering future relocation, meaning his tax position could change materially over the coming years.

Several competing objectives needed to be balanced:

Generate £2.25 million of liquidity.
Minimise unnecessary tax leakage.
Reduce concentration risk over time.
Preserve flexibility around future tax residency changes.
Maintain long-term wealth accumulation.

The client’s instinct was to focus on the immediate transaction.

His private banker wanted to help him understand the broader implications of today’s decision on the next twenty years of his financial future.

Why Traditional Planning Approaches Fell Short

Historically, discussions like these often revolve around spreadsheets, isolated tax calculations, and investment projections. The challenge is that each analysis tends to answer only one question at a time.

The private banker needed a way to demonstrate:

The impact of selling stock today.
The impact of borrowing against investments.
Future tax consequences.
Loan servicing costs.
Long-term wealth outcomes.
Potential effects of future international relocation.

Without a comprehensive cashflow model, it would be difficult for the client to visualise the alternatives confidently.

The conversation risked becoming centred on a single transaction rather than a holistic wealth planning strategy.

How the Banker Approached the Problem

Rather than starting with products, the private banker began with the client’s long-term objectives.

The discussion focused on questions such as:

What role would this property play in the family’s future?
Was relocation likely?
How important was maintaining flexibility?
What level of concentration risk was acceptable?
What legacy objectives existed for the next generation?

The banker then built a long-term financial forecasting model covering:

Current assets and liabilities.
Existing income streams.
Equity compensation.
Future spending assumptions.
Property acquisition costs.
Potential relocation scenarios.
Retirement planning objectives.

This shifted the conversation away from a single transaction and towards a comprehensive cross-border planning exercise.

Using WealthOptic

Using WealthOptic, the banker created a multi-decade cashflow modelling projection that allowed the client to visualise different paths side by side.

The platform made it possible to compare:

Scenario A: Sell Shares

Under this scenario:

£2.25 million of stock would be sold.
£270,000 capital gains tax would be payable immediately.
Net proceeds would fund the property purchase.

Scenario B: Lombard Loan

Under this scenario:

A £2.25 million Lombard loan would be secured against the investment portfolio.
No shares would be sold immediately, and capital gains tax would be deferred.
Loan interest costs would be incorporated into annual cashflows.
The shares could be sold over a number of years after retirement, when the client was a lower rate tax-payer.
Inflation, eating away at the debt in real terms, means the clients is £1,000,000 better off over their lifetime.

Rather than discussing abstract financial concepts, the client could see the consequences of each decision unfold over time.

The Real Impact

After reviewing the scenarios, the client agreed that a lombard loan was the best way forwards.

The decision was not driven solely by tax savings. Instead, it reflected a broader understanding of how each option affected his overall financial future.

The client could clearly see:

The cost of crystallising gains immediately.
The impact of loan servicing.
The effect of retaining invested capital.
The consequences for future retirement planning.
The flexibility provided by delaying major tax decisions.

For the first time, the discussion moved beyond “Should I sell shares?” and became “Which strategy best supports my long-term goals?”

That shift fundamentally changed the quality of the decision-making process.

Commercial Outcome for the Banker

The exercise created substantial value for the private banker. Rather than being viewed as someone arranging a loan or facilitating an investment transaction, the banker became a strategic adviser.

The modelling process strengthened trust and deepened the relationship. Additional benefits included:

Retained AUM and increased lending.
Greater client retention.
Additional family planning opportunities.
Referrals to other internationally mobile executives.

The client later introduced two colleagues facing similar equity concentration challenges.

The private banker also found that the visual planning process accelerated decision-making and reduced the number of follow-up meetings required to reach agreement.

Key Takeaways

For private bankers serving internationally mobile high-net-worth clients, decisions rarely exist in isolation.

Tax considerations, investment strategy, retirement planning, and future residency plans are often deeply interconnected.

This case demonstrates how cashflow modelling and financial forecasting can help advisers compare complex alternatives within a single framework.

By using WealthOptic to model selling securities, borrowing against investments, and phased diversification strategies, the private banker was able to demonstrate the long-term implications of each choice rather than focusing solely on the immediate transaction.

The result was a more informed client decision, stronger adviser-client engagement, and a planning process that aligned short-term liquidity needs with long-term wealth objectives.

For advisers working in cross-border planning and international financial planning, the ability to visualise these trade-offs can be the difference between providing a recommendation and delivering genuinely strategic advice.
