Finding the right amount of leverage for your portfolio

How leverage can be the best option to enhance returns and achieve your goals

Share this page

Investors have been very fortunate in recent years. Especially in the US, stocks and bonds have both delivered solid returns, in part fueled by decades of falling interest rates and rising valuations. Going forward, the UBS Chief Investment Office (CIO) expects these tailwinds to fade, resulting in an environment of lower returns over the next few market cycles.

Fortunately, investors have options for improving returns while still managing risks. Click the speaker icons throughout this interactive experience to hear CIO analysts discuss how diversification—and the prudent use of borrowing strategies—can help to solve the quandary of lower returns.

Forward-looking returns are likely to be lower, but diversification can help

Why consider borrowing now?

Even before the global recession sparked by COVID-19, interest rates were already near record lows. Today, on the heels of unprecedented levels of monetary stimulus, investors have the opportunity to lock in some of the lowest borrowing costs in history.

With an equally unprecedented amount of fiscal stimulus also entering the economy—and COVID-19 vaccines allowing for life to begin returning to normal—we expect the current bull market to enjoy solid returns in the years to come.

Potential advantages of applying leverage

Diversification has been called "the only free lunch in investing" because it can allow investors to manage the portfolio's volatility, achieving a higher level of expected return per unit of expected risk.

Adding leverage to a diversified portfolio can allow investors to achieve similar (and in some cases potentially higher) expected returns as if they simply added to stocks and other risk assets, but with a higher expected risk-adjusted return than shifting to a higher allocation in stocks.

With superior risk-adjusted return potential, leveraged diversified portfolios can produce greater and more consistent portfolio growth potential than portfolios that seek to increase expected returns by sacrificing diversification to increase the allocation to stocks.

Beyond a point, adding to equities increases portfolio risk more than it increases portfolio return

Why keep an allocation to bonds?

When it comes to implementing portfolio leverage, our primary goal is to enhance after-tax portfolio growth while maintaining diversification.

Despite low interest rates and yields in today's market, bonds play a critical role as a portfolio diversifier. Because interest rates tend to fall (and bond prices rise) during bear markets and other bouts of market volatility, high-quality bonds have the potential to reduce portfolio volatility more than they reduce portfolio return. During bear market environments, interest rates tend to fall and bond prices rise; bonds can therefore provide a "safe haven" during these difficult periods that play an essential role in a portfolio.

With these factors in mind, keeping a healthy allocation to bonds in a well-diversified portfolio and then applying leverage can help an investor achieve several objectives:

More return potential

Adjusting portfolio leverage can often be done without the need to sell assets and realize capital gains taxes (a potential cost of changing an unleveraged portfolio's asset allocation).

Smoother returns

Keeping the assets invested in a well-diversified asset allocation can result in the smoother compounding of returns, and can mitigate the duration of drawdowns and recovery times.

Better risk-adjusted returns

When compared to simply adding to stocks and other risk assets, leveraged portfolios can provide the potential for higher returns and more return per unit of risk.

Expected impact

Prudent leverage may improve returns more than adding to risk assets

Expected risk and return after various borrowing costs and amounts of leverage
 

When compared to the unleveraged portfolios, leveraged portfolios can offer a superior expected return and risk-adjusted return as long as the future returns of the portfolio exceed the financing costs.

For example, a borrowing cost of 3.25% both significantly enhances expected returns and results in a more “efficient” (offering a higher return per unit of risk) portfolio than re-positioning an allocation to the next risk portfolio without leverage. As borrowing costs decrease, we would expect both the return enhancement and the “efficiency” opportunity of using leverage to be greater.

In our report, we determined a maximum recommended leverage for each risk profile. This threshold is calibrated to maintain a significant buffer from a margin call, based on our analysis of historical drawdowns and margin call thresholds in scenarios where investors employed leverage at the worst possible time, i.e. at a market peak right before a drawdown. For each risk profile, any portfolio leverage above the maximum recommended leverage ratio would have resulted in a margin call during the global financial crisis (the worst drawdown since the great depression). Investors should be very cautious about exceeding this threshold, only doing so when there is a dependable source of outside assets or financing that can be relied upon even in the worst market environments. Staying under the maximum recommended leverage threshold does not guarantee that any individual investor or strategy will avoid potential margin calls, especially if you plan to purchase less-liquid investments.

How borrowing can help you achieve your goals

Many investors dislike taking on debt, but it can often be the best option available. To help make this assessment, we recommend that you consider borrowing strategies through the lens of the UBS Wealth Way, which can help you to determine the best solution for meeting your family's unique objectives.

We see four main reasons to consider portfolio leverage:

  1. To provide a "bridge loan" or secure liquidity
  2. To increase diversification
  3. To increase return potential
  4. To mitigate taxes

The UBS Wealth Way framework can help to judge whether a particular borrowing strategy's potential rewards outweigh its costs and risks to result in better outcomes or a higher likelihood of successfully meeting your goals. We recommend using the Liquidity. Longevity. Legacy. framework to build a purpose-built investment approach (including portfolio loans and other borrowing resources) across three strategies:

We often recommend that investors consider setting aside borrowing capacity to finance spending, either as an alternative to setting aside large cash holdings that offer limited interest income, or as an alternative to selling investment assets that have greater return potential.

In this table, we show a case study of how borrowing to fund spending can improve returns. In this example, Mark has USD 3,000,000 invested in a Moderately Aggressive portfolio (roughly 70% stocks and 30% bonds). He needs to make a USD 350,000 tax payment, and can choose to raise funds either by liquidating a part of his portfolio, or by tapping into his securities-backed credit line at an interest rate of 2.25%.

As shown in the table, Mark could have approximately USD 15,462 more in his account if he borrows to make the tax payment, and if markets provide an average return over the next year. This analysis doesn't include the impact of realizing capital gains taxes, which could further enhance the value of borrowing, especially if Mark has another source of income to pay down the loan balance. 

How to effectively manage leverage

Loan-to-value ratio

Like any loan, there is a maximum amount that you can borrow off of a securities-backed credit line, determined by the expected risk of the securities that you own in the accounts you've pledged as collateral. For example, you may be able to borrow 50% of the asset value of a stock, 70% of the value for a high-yield bond fund, and 90% for a US Treasury fund. These ratios are known as "release rates."

Your credit line approval amount will reflect the weighted average of the release rates and market value of each of the holdings in the accounts that you have pledged as collateral for the loan. If you have more invested in low-risk securities, your credit line approval amount will be higher than if you have a portfolio of high-risk investments, all things being equal.

When you take out a securities-backed loan, the bank will keep an eye on your loan-to-value (LTV) ratio to make sure that your loan doesn't exceed the LTV associated with your approved credit line balance. If your portfolio goes higher, your LTV ratio will fall and your approval amount will rise; if the portfolio falls, your LTV ratio will rise and your approval amount will fall.

If your portfolio's LTV rises above the level approved by the bank, you could be subject to a "margin call," which may require you to add assets to your account or sell investments to pay down the credit line balance. This means that it's important not to draw your entire approval amount from the loan unless you have other resources to pay down the balance.

Rebalancing your loan

One advantage of securities-backed credit lines—as opposed to some other types of debt—is that you can usually pay down the loan balance, or draw additional capital from the credit line, without incurring a transaction cost.

We expect that most investment portfolios will grow faster than the cost of borrowing, most of the time. As a result, it’s likely that your LTV ratio will gradually decline over time. If you wish to maintain a consistent LTV ratio, which may help you to boost your long-term expected returns, you can draw additional assets from your loan and add them to your investment account over time. It’s important that you do not rebalance your portfolio to an LTV that exceeds your portfolio’s maximum recommended leverage ratio, because this could result in a higher risk of margin calls.

Next steps

    1. Speak with your financial advisor about your borrowing capacity and the interest rate available for a securities-backed credit line tied to your portfolio.
    2. If you are planning to tap into your borrowing capacity, ask your financial advisor whether a fixed-rate loan makes sense for you.
    3. Speak with your tax advisor about whether you could deduct the interest on an investment loan from your taxable investment income.
    4. Consider whether borrowing might help you fund your spending without realizing capital gains taxes, keeping your portfolio generating growth and income.
    5. When seeking a higher return, consider portfolio leverage as an alternative to shifting your allocation from bonds to stocks and other risk assets.
