Borrowing Against Your Investment Portfolio: Benefits, Risks, and Lombard Lending Strategies
Written by: Nicole Newman, MBA, CEPA
Summary: Borrowing against an investment portfolio can create liquidity without selling assets, but it introduces risks such as margin calls, leverage exposure, and rising borrowing costs that must be carefully managed.
When Does Borrowing Against an Investment Portfolio Make Sense?
Borrowing against an investment portfolio may make sense for high-net-worth investors who need liquidity for business opportunities, real estate purchases, or large financial commitments while keeping their assets invested. It is most appropriate when leverage remains conservative and the portfolio is diversified.
Key Takeaways: Borrowing Against Investable Assets
Borrowing against an investment portfolio (also called Lombard lending or securities-based lending) allows investors to access liquidity without selling assets or triggering capital gains taxes.
The primary risks include margin calls, forced asset sales, and losses during market volatility, which can occur if portfolio values decline significantly.
Leverage can amplify returns, but it also magnifies potential losses if borrowing levels are too high or markets decline.
Maintaining conservative loan-to-value ratios and diversified portfolios helps reduce the risk of margin calls and forced liquidation.
Securities-based borrowing is not appropriate for every investor, particularly those with concentrated portfolios or short investment horizons.
Real-world scenarios show both successful outcomes and serious financial consequences, depending on how leverage is managed.
Professional financial guidance is essential to ensure borrowing strategies align with long-term wealth preservation and family governance goals.
As an advisor, I often see families trying to balance their desire for continued growth with the need for immediate liquidity. When you have a complex financial situation, securing cash without disrupting a carefully constructed investment portfolio is a common objective.
Earlier in my career working in corporate strategy and mergers and acquisitions, these types of decisions were viewed through the lens of capital structure and strategic leverage. Companies routinely evaluate when to raise debt, preserve equity ownership, and maintain liquidity in order to pursue opportunities. Over time, I realized many of those same principles apply to managing a family’s balance sheet. Thoughtful wealth management often involves making strategic decisions about liquidity, leverage, and long-term capital allocation.
One method that frequently comes up in these discussions is leveraging credit against investable assets. This approach, sometimes called Lombard lending or securities-based borrowing, allows investors to use their portfolio as collateral for a loan. Instead of selling off equities or bonds to fund a major purchase, a business venture, or a philanthropic goal, investors can borrow against the value of those assets. The primary appeal is that it allows capital to remain fully invested while still providing access to liquidity when needed.
These strategies are often most effective when:
A family or individual has a diversified portfolio large enough to absorb market fluctuations
Liquidity is required for a large purchase or business opportunity without triggering capital gains taxes
Borrowing is limited to a conservative percentage of the portfolio’s value
There is a long investment time horizon and no immediate need to liquidate assets for living expenses
Cash flow from new investments or other sources can comfortably cover loan interest and repayments
Market conditions are relatively stable or experiencing moderate growth
However, these approaches may not be appropriate in certain situations, including:
Portfolios that are heavily concentrated in volatile or illiquid assets
Situations where borrowing is intended for speculative or short-term purposes
Circumstances where overall leverage (debt-to-equity ratio) is already high, increasing vulnerability to market corrections
When a family relies on their investment portfolio for essential living expenses
Periods of heightened market volatility or economic uncertainty
Environments where rising interest rates could make repayments difficult or erode the strategic advantage of borrowing
That said, as a fiduciary, I believe it is essential to approach this strategy with a high degree of caution. While strategic borrowing can be an effective tool for preserving and growing multigenerational wealth, it is not universally appropriate. When mismanaged or used in the wrong circumstances, leveraging investable assets can expose families to significant financial risk.
At Stone Creek Advisors, we further safeguard our clients by carefully measuring the amount of risk taken for each unit of return and managing portfolios on a risk-adjusted basis. By quantifying how much risk is taken relative to expected returns and adjusting our strategy accordingly, we aim to reduce exposure to severe market corrections.
This disciplined approach is particularly important in today’s evolving global environment. As our Chief Investment Officer, Kasey Wopperer, recently discussed in her analysis of deglobalization and the potential for more frequent market volatility, shifting geopolitical and economic dynamics may increase the importance of active, top-down portfolio management. In that type of environment, portfolios must be prepared to withstand volatility and avoid forced asset sales or margin calls that could otherwise result in substantial losses.
My goal is to provide the comprehensive education needed to evaluate this complex financial strategy. By understanding the mechanics, potential benefits, and serious risks involved, families can make informed decisions that align with their long-term legacy and financial goals.
Understanding Lombard Lending and Strategic Leverage
Lombard lending is a specialized financial service where a lender provides a loan secured by a borrower's liquid assets, such as stocks, bonds, or mutual funds. The loan amount is typically a percentage of the portfolio's total value, known as the loan-to-value (LTV) ratio. Because the loan is fully collateralized by liquid investments, the interest rates are often more favorable than unsecured borrowing options.
For individuals with significant assets, this type of credit facility can act as a bridge. It provides capital for immediate needs, such as a real estate acquisition or a capital call for a private equity investment, without triggering the consequences of liquidating public market positions.
What Is Lombard Lending?
Lombard lending is a loan secured by liquid investment assets such as stocks, bonds, or mutual funds. Instead of selling investments to generate cash, investors borrow against their portfolio value, allowing assets to remain invested while providing liquidity.
Strategic Benefits of Borrowing Against Your Investment Portfolio
When applied correctly and conservatively, leveraging investable assets can provide distinct advantages for wealth management and estate planning.
Enhancing Liquidity Without Selling Assets
The most immediate benefit of securities-based borrowing is the creation of liquidity. Selling assets to generate cash disrupts your strategic asset allocation. It removes those funds from the market, meaning you miss out on potential future growth, dividend payments, and compounding interest. By borrowing against the portfolio instead, your investments remain intact and continue to work toward your long-term goals.
Capitalizing on Tax Advantages
Selling appreciated assets generally triggers capital gains taxes. Depending on the size of the liquidation and your tax bracket, this can result in a substantial tax liability, effectively reducing the total amount of capital you have available. Borrowing against your assets does not trigger a taxable event. The loan proceeds are tax-free, and in some specific business or investment scenarios, the interest paid on the loan may even be tax-deductible. Always consult with a tax professional to understand how this applies to your bespoke financial situation.
The Potential for Amplified Returns
In certain scenarios, families use leveraged credit to invest in additional opportunities. If the return on the new investment exceeds the cost of borrowing, the overall wealth of the family increases. This arbitrage strategy can amplify returns, but it fundamentally requires a sophisticated understanding of both the new investment's viability and the carrying costs of the loan.
The Underlying Risks of Borrowing Against Your Portfolio
The benefits of strategic borrowing are compelling, but they are accompanied by serious risks. As advisors dedicated to your family's financial security, we emphasize that these risks must never be underestimated.
Navigating Margin Call Risk
The most significant risk associated with Lombard lending is the possibility of a margin call. Because your loan is secured by the fluctuating value of your investment portfolio, a market downturn can cause the value of your collateral to drop. If the portfolio value falls below the lender's required minimum threshold, the lender may require you to:
Deposit additional cash or securities
Repay a portion of the loan
Allow the lender to liquidate assets
Forced liquidation during a market downturn can lock in losses and create unexpected tax consequences.
If you cannot meet this demand quickly, the lender has the right to forcefully liquidate your assets at currently depressed market prices. This locks in market losses, creates unexpected tax liabilities, and can severely impair your family's wealth.
Market Volatility Risk
Investment portfolios fluctuate in value. When borrowing against assets, these fluctuations directly affect the stability of the loan. A significant market decline can rapidly increase the loan-to-value ratio and trigger margin calls.
Portfolios that are highly concentrated or heavily exposed to volatile sectors are particularly vulnerable to this risk.
Interest Rates Risk
Securities-based loans typically have variable interest rates. If interest rates rise, the cost of borrowing increases. Higher borrowing costs can:
Reduce the financial benefit of the strategy
Create cash-flow pressure
Make refinancing or repayment more difficult
Over-Leverage and Excess Borrowing Risk
Borrowing too much against a portfolio significantly increases financial vulnerability. Excessive leverage leaves little room for market fluctuations before a margin call occurs.
Many prudent wealth managers recommend borrowing well below the maximum loan-to-value allowed by lenders, often keeping leverage below 20–30% of portfolio value.
Liquidity Risk
If the portfolio is required to support loan repayments during a market downturn, investors may be forced to sell assets at unfavorable prices. This can disrupt long-term investment strategies and permanently impair capital.
When the Strategy Becomes Dangerous
Borrowing against investments becomes particularly risky when:
Portfolios are concentrated in a single asset or sector
Loan-to-value ratios exceed conservative levels
Borrowed funds are used for speculative investments
The investor relies on the portfolio for essential living expenses
Markets experience sustained volatility or decline
Is This Strategy Appropriate for Your Family?
Determining whether to use credit against investable assets is a collaborative process. We guide our clients through a rigorous evaluation to ensure any borrowing aligns perfectly with their family governance structure and long-term legacy goals.
Evaluating Debt-to-Equity Ratios
A thorough assessment begins with your current debt-to-equity ratio. Taking on additional leverage makes sense only if your overall balance sheet remains exceptionally strong. We analyze all existing liabilities, including mortgages, business loans, and other credit facilities, to ensure that a new securities-based loan does not push your total leverage into a dangerous territory.
Time Horizons and Personal Risk Tolerance
Leverage is generally unsuitable for short-term, speculative maneuvers or for families who rely on their portfolio for immediate, necessary living expenses. We evaluate your investment time horizon carefully. Furthermore, personal risk tolerance is paramount. If the thought of a market downturn and a potential margin call causes significant distress, this strategy is likely not the right fit, regardless of the mathematical benefits.
Case Studies: The Duality of Leverage
To illustrate the practical applications and dangers of this strategy, we can examine hypothetical scenarios based on common wealth management situations.
Successful Strategic Leverage
Consider a family business owner who needs $2 million to acquire a competitor. The family's $15 million investment portfolio is highly diversified and performing well. Selling $2 million in stock would trigger over $400,000 in capital gains taxes. Instead, they secure a Lombard loan at a favorable interest rate, borrowing against the portfolio. The acquired business generates immediate cash flow that easily covers the interest payments on the loan. The family retains their full market exposure, avoids a massive tax bill, and successfully expands their enterprise.
The Consequences of Over-Leveraging
Conversely, consider an individual with a $6 million portfolio heavily concentrated in technology stocks. They take out a $3 million loan to purchase luxury real estate, pushing their loan-to-value ratio to 50%. A sudden correction in the tech sector causes the portfolio value to plummet by 40%, dropping the collateral value to $3.6 million. The lender issues a margin call, demanding immediate capital. Unable to produce cash quickly, the individual watches as the lender force-sells assets at the bottom of the market. The portfolio is decimated, and the remaining assets are insufficient to maintain the family's lifestyle and philanthropic commitments.
Best Practices for Preserving Wealth
If you and your advisors determine that leveraging credit is appropriate for your specific needs, strict adherence to best practices is vital to protect your financial foundation.
The potential benefits of leveraged investing can still be achieved while minimizing risk by following these strategies:
Conservative Leverage: Borrowing at lower loan-to-value ratios reduces the likelihood of a margin call and provides greater cushion against market volatility.
Diversification: Spreading leverage across multiple asset classes can mitigate concentration risk and reduce overall portfolio volatility.
Asset Quality: Investing in high-quality assets, such as blue-chip stocks or investment-grade bonds, can reduce the risk of default in case of market downturns.
Regular Monitoring: Regularly reviewing and adjusting leverage levels based on market conditions can help manage potential risks.
Setting Conservative Collateral Limits
We strongly advise against borrowing the maximum amount a lender allows. If a bank permits borrowing up to 70% of a portfolio's value, we typically recommend limiting the loan to 15% or 20%. Maintaining a massive buffer ensures that even in the event of a severe, 2008-style market crash, your portfolio value will remain comfortably above the margin call threshold.
Maintaining Diverse Portfolios for Risk Mitigation
Lenders look favorably upon highly diversified portfolios. Borrowing against a portfolio concentrated in a single stock or sector is exceptionally dangerous due to the risk of localized volatility. A bespoke, globally diversified portfolio containing a mix of equities, high-quality fixed income, and alternative investments provides a much more stable collateral base.
Balancing Opportunity With Financial Security
Using investment portfolios as collateral for credit can be a powerful wealth-management tool when applied with discipline. It offers families the flexibility to seize opportunities, fund philanthropic endeavors, and manage tax liabilities with remarkable efficiency. However, the use of leverage magnifies outcomes, multiplying both gains and losses.
