What Is a Securities-Backed Line of Credit—and When Does It Make Sense?

Accessing liquidity doesn’t always mean selling investments. For many investors—especially those with sizable taxable portfolios—selling assets can trigger capital gains, disrupt long-term strategy or force decisions at the wrong time. A securities-backed line of credit offers an alternative way to access cash while keeping your portfolio intact. This form of credit is also often called an SBLOC or pledged asset line, as well.

Used thoughtfully, this tool can provide flexibility without undermining your broader financial plan.

How a Securities-Backed Line of Credit Works

An SBLOC allows you to borrow against eligible investment assets held in a brokerage account. Instead of liquidating positions, those assets are pledged as collateral for a revolving line of credit. The credit line can be used for a wide range of purposes, from short-term cash needs to planned expenses.

Key characteristics typically include:

• No required liquidation of investments, allowing your portfolio to remain invested
• Flexible access to funds, similar to a home equity line of credit
• Variable interest rates, often tied to short-term benchmarks
• No fixed repayment schedule, though interest accrues while balances are outstanding

Because the loan is collateralized by marketable securities, underwriting is usually streamlined compared to traditional lending.

When an SBLOC Can Be a Smart Planning Tool

A securities-backed line of credit isn’t a replacement for cash reserves or long-term financing, but it can be highly effective in specific situations. It’s most appropriate when liquidity needs are temporary, strategic or tied to timing considerations rather than ongoing spending.

Common planning scenarios include:

• Covering short-term cash needs without triggering capital gains taxes
• Bridging timing gaps, such as tax payments, real estate purchases or business investments
• Managing irregular income, especially for business owners or equity-compensated professionals
• Providing flexibility during market volatility, avoiding forced selling in down markets

In these cases, the ability to borrow against appreciated assets can preserve both tax efficiency and long-term investment discipline.

Risks and Considerations to Keep in Mind

While SBLOCs offer flexibility, they’re not without risk. Because the loan is tied to market values, a significant market decline can reduce available credit or require additional collateral. Interest rates can rise, increasing borrowing costs. Relying too heavily on leverage can also introduce unnecessary stress into a financial plan.

That’s why an SBLOC works best when integrated into a broader strategy that accounts for cash flow, taxes, risk tolerance and long-term goals.

Liquidity Without Disruption—When Used Correctly

A securities-backed line of credit can be a powerful planning tool when used intentionally and conservatively. It provides access to liquidity while allowing investments to stay aligned with long-term objectives.
