Portfolio Line of Credit vs Margin Power: Borrowing to Spend vs Borrowing to Invest

If you have an investment portfolio, you might have more borrowing options than you think. A portfolio line of credit is a type of loan that allows eligible investors to borrow money using their investments as collateral without having to sell them.

This means you might be able to access cash while keeping your investments in the market. It could be an option if you need short-term funds or do not want to sell investments you plan to hold long term. However, how much you borrow could change as the value of your investments rises or falls.

In this article, understand what a portfolio line of credit is, how borrowing against investments works, and how it compares to other options like personal lines of credit or home equity loans. We also explore the key risks to understand before borrowing and how Questrade’s Margin Power might fit into these decisions, depending on eligibility and your comfort with risk.

What is a portfolio line of credit?

A portfolio line of credit (investment line of credit) is a way to borrow money using your investments as security. Instead of selling your investments when you need cash, you might be able to borrow against their value.

Your investments stay in your account and continue to grow or change with the market. The amount you could borrow depends on things like the total value of your portfolio, the types of investments you hold, and whether they meet eligibility rules.

You pay interest on the money you borrow, not on your full credit limit. This makes it a flexible option if you do not need all the funds at once.

Understand that investment values could increase or decrease. Your borrowing limit could change as your portfolio fluctuates. If your investments drop in value, the amount you could borrow might go down as well.

How does borrowing against investments work?

Borrowing against investments means using your investment portfolio as security to access credit. In simple terms, your investments act as collateral, which is something the lender could rely on if the loan is not repaid.

Here is how it usually works:

• You hold eligible investments in your account, such as stocks, ETFs, or mutual funds

• The provider reviews your portfolio and determines which investments could be used as collateral

• You are given a credit limit, which is the maximum amount you might be able to borrow

• If you choose to borrow, you could take out funds up to your available limit

• You only pay interest on the amount you actually borrow

Your borrowing power could change over time because investment values move up and down:

• If your portfolio value increases, your borrowing limit might increase

• If your portfolio value decreases, your borrowing limit might decrease

It is important to understand the risks of using your investments as collateral for borrowing. Because borrowing is linked to market performance, your access to credit is not fixed and might change as your portfolio value moves up or down. Depending on the product terms, you might need to repay part of what you have borrowed or take other steps to stay within required limits.

Portfolio line of credit vs. margin account: are they the same?

A portfolio line of credit and a margin account are similar, but they are not the same.

A margin account is mainly used for investing. It lets you borrow money to buy more investments in your brokerage account. This is called investing on margin, and it increases your exposure to the market, which could increase both gains and losses.

A portfolio line of credit is usually more flexible. It might let you borrow against your investments for broader needs, not just for investing. The exact use depends on the product rules.

There are also other differences:

• Eligibility rules could be different

• Interest rates might not be the same

• Borrowing limits could vary

• Risk rules and requirements are not identical

Both products are affected by market changes. If your investments go up or down in value, your borrowing power might also change.

Different providers might treat these products differently. For example, Questrade’s Margin Power has its own rules, so check the official details before using it.

Portfolio line of credit vs. HELOC vs. personal line of credit

A portfolio line of credit, a HELOC, and a personal line of credit use different types of security to borrow money.

A portfolio line of credit is backed by your investments, such as stocks or ETFs. It might let you borrow money without selling your investments. However, your borrowing limit could change as investment values change.

A HELOC (home equity line of credit) is backed by your home. It uses the value of your property as security. It is usually available to homeowners and is often used for larger expenses like renovations or debt consolidation. You need to have enough home equity to qualify.

A personal line of credit is based on your credit score and income. Since there is no collateral, borrowing limits might be lower, and interest rates might be higher than for secured options.

You could also choose to sell your investments instead of borrowing. This avoids taking on debt, but it might trigger taxes or fees and could change your long-term investment plan.

Which option might fit different situations:

• A HELOC might work for homeowners who have enough equity in their home

• A personal line of credit might work if you want borrowing flexibility without using assets as collateral

• A portfolio line of credit might work for investors who want to borrow against their investments and are comfortable with the risks

Potential benefits of a portfolio line of credit

A portfolio line of credit could offer useful benefits, especially if you want to access money without selling your investments. However, each benefit still comes with risks.

• Access to cash without selling investments: You might be able to borrow while keeping your investments invested. This could help avoid selling at an unwanted time, but your portfolio value could still change.

• Flexible borrowing: You could borrow what you need, when you need it. However, your limit might change based on investment performance.

• Interest on what you use: You only pay interest on what you borrow, but costs could build over time.

• Might help you keep your investment plan: It could help you stay invested without changing your strategy, but borrowing risks still apply.

• Helpful for short-term needs: It might help with short-term cash flow, but repayment is still required, and limits could change with the market.

Risks and considerations before borrowing against investments

Borrowing against investments could give you access to credit, but it also has important risks to understand.

Your investment value might change

The value of your investments could go up or down. Because your investments are used as collateral, a drop might reduce how much you could borrow. In some cases, you might need to repay part of what you borrowed or meet certain requirements.

Borrowing costs matter

You pay interest on the money you borrow. These costs could add up over time, even if you only borrow a small amount. It is important to consider whether the cost fits your budget.

You need a repayment plan

Have a clear plan for how you will repay what you borrow. Without a plan, it could become harder to manage if your financial situation or the market changes.

This is not risk-free access to cash

Borrowing against investments is not the same as using savings. Your borrowing limit could change if markets move, and your repayment responsibilities still apply even if your investments fall.

Losses can exceed your initial investment: Unlike cash accounts, borrowing against investments can result in losing more money than you deposited, requiring you to pay back a cash deficit out-of-pocket. 

Not all investments are eligible, and rules vary by provider. This option might not be suitable for every investor, especially if you are not comfortable with market fluctuations or borrowing risk.

Common use cases for a  portfolio line of credit?

A portfolio line of credit allows investors to borrow against eligible non-registered investments held as collateral, without selling those holdings. It is typically compared against other borrowing options, such as a HELOC or a personal line of credit, when evaluating access to liquidity.

Some characteristics of this borrowing option may include:

• Borrowing is secured against eligible non-registered investments rather than requiring the sale of those holdings

• Access to funds can address short-term liquidity needs without disrupting an existing investment position

• The borrowing limit is tied to the value of the pledged investments and can change as that value changes

• Approval and terms depend on eligibility criteria set by the lender

• Repayment terms and costs vary and are typically structured around interest charges on the amount borrowed

Key limitations

A portfolio line of credit has structural characteristics that distinguish it from other forms of borrowing:

• Borrowing limits are tied to portfolio value, so market volatility can directly affect how much credit remains available

• Funds are not guaranteed to remain accessible under all market conditions, since eligibility and limits depend on the value of the underlying collateral

• Because loan balances exist independent of investment performance, repayment obligations continue regardless of how the pledged investments perform

• Using investments as collateral introduces mechanics — such as the potential for a margin-call-like shortfall — that differ from unsecured borrowing options

• Interest and other borrowing costs apply to the amount drawn, in addition to the risks associated with the underlying investments themselves

Comparing this option against other borrowing products, and understanding the associated costs, terms, and risks, can help clarify whether the product's structure aligns with an individual's broader financial circumstances.

Questions to ask before using a portfolio line of credit

Before borrowing against your investments, ask yourself these questions:

• Why do I need the money? Is it for a short-term need or a larger financial goal?

• How much do I need to borrow? Borrow only what you need and could afford to repay.

• How will I repay it? Ensure you have a clear repayment plan.

• What if my investments lose value? Understand how a drop in your portfolio could affect your borrowing limit.

• What interest rate will I pay? Know how much borrowing will cost over time.

• Are there any fees or account requirements? Check the product details before you apply.

• Which investments are eligible? Not all investments could be used as collateral.

• Have I compared other options? Consider alternatives like a personal line of credit, a HELOC, or selling investments.

• Am I comfortable using my investments as collateral? Make sure you understand the risks before you borrow.

Is a portfolio line of credit right for you?

A portfolio line of credit might be worth exploring if you want access to cash without selling your investments. It could offer flexibility, but it also comes with risks. Your borrowing limit could change if your investments fluctuate, you pay interest on what you borrow, and you need a plan to repay it.

Before deciding, compare it with other options, such as a HELOC, a personal line of credit, or selling your investments. The best choice depends on your financial goals, your assets, your eligibility, and your comfort with risk.
