The asset side of an investor's balance sheet gets all of the glory, while borrowing is often viewed primarily as a costly or risky solution, only to be used in emergencies. While it's true that leverage doesn't directly contribute to portfolio gains, it can enable them and also help to manage costs and risks. As we discuss in Why borrow if you're already wealthy? , we believe investors should consider liability management as a core component of their toolkit.
For an investor considering borrowing strategies, it's often challenging to know where to begin. In this blog, we outline some of the levers and tools in the borrowing toolkit, and give a quick overview of how to decide which is appropriate in a given situation. These decisions should not be made in a vacuum. It's vital that the asset and liability strategies are coordinated, working in concert to help meet your goals. Having the ability to borrow is a key flexibility for managing bear markets and unexpected expenses. Taking on too much debt can have the opposite effect, so always make sure your borrowing plan is resilient against uncertainties.
Broadly speaking, there are two core decisions involved with developing a borrowing strategy. First, an investor can either borrow at a fixed rate over a specific maturity (also called a "tenor") or they can choose to borrow at a variable or "floating" interest rate. A fixed-rate loan can be made over various tenors, ranging from just a few weeks to several years. Second, an investor considering a fixed-rate borrowing strategy must also evaluate the cost of rolling a short-tenor loan versus locking in a longer loan tenor.
When is it better to borrow at a fixed rate versus a floating rate?
Historically, the shape of the yield curve and the expectation of future interest rates are strong determinants of whether individuals should borrow at a fixed versus a floating rate. However, an individual's short-term liquidity needs and the benefit of matching future cash flows also play an important role over the long term.
Fixed interest rate means repayment of the loan is fixed with equal installments throughout the loan tenure. This is often an option for mortgages, securities-backed loans (SBLs), and other loans, but may not be available for all loans. The advantage of borrowing at a fixed rate is that irrespective of market conditions, the interest rate remains fixed thus providing stable funding costs until maturity. For borrowers looking to match their asset and liabilities, a fixed borrowing rate brings clarity and certainty to future loan obligations. The disadvantage, however, is that if interest rates decline, a fixed-rate loan will not benefit from reduced rates without incurring additional costs.
Floating interest rates imply that the rate of interest fluctuates with market conditions. These loans typically require a lower initial payment than fixed-rate loans, and are attractive to liquidity-constrained borrowers or those who may prefer greater monthly cash flows to reinvest elsewhere.1 However, for floating-rate loans, monthly installments are not even and may lead to variability within managing asset and liability cash flows. With floating-rate loans, only the initial interest rate is known, and therefore the borrower must form an expectation about the future direction of interest rates.
Interest rates, shape of the yield curve, and fixed versus floating
The shape of the yield curve—short-term rates versus long-term rates-influences the cost of borrowing at fixed versus floating rate. Short-end yields, which determine floating-rate borrowing costs, are influenced by near-term monetary policy, while longer-term yields—which more closely determines the level of fixed rates—are driven by growth and inflation expectations. Mortgages in most countries are often tied to short-term interest rates, and a change in the policy interest rate by the central banks can shift monthly payments fairly quickly (the US is a notable exception, where 30-year fixed rate mortgages are common).
As shown below, the spread between a floating versus fixed compresses as the shape of the curve compresses.

When interest rates are low, the borrower may anticipate rising rates going forward, and opt to lock in at a lower rate to minimize outgoing cash flows on a forward basis. However, for investors who prefer the initial lower cash flows to reinvest and can afford to take on higher monthly payments in the future (or have the capacity to pay down the loan earlier) floating rate loans may be preferable.
What about borrowing in other markets?
In some cases, investors may be able to borrow in another market at a lower borrowing cost, but the loan must be repaid in another currency. In these situations the lower interest rate environment may be a boon but the investor must be mindful of the risk of a currency mismatch between the portfolio and the loan. This risk must be incorporated into the risk-reward assessment.
Conclusion: Coordinate asset and liability strategies to mitigate risk and enhance returns
In summary, we recommend choosing a loan tenor that is in line with interest rate expectations and risk profile so that funding cost risks are under control. It's also helpful to align loan tenor with a planned asset sale or liquidity event (e.g. a bonus). When borrowing using an asset-backed lending facility, it is important to consider the correlation between the asset and interest rates. For example, a well-diversified portfolio of stocks and bonds will have little or positive correlation to rising interest rates, but fall in value during drastically falling interest rates (which tend to occur during growth soft patches).
In addition, consider the impact of interest rates on your assets' cash flow generation; for example, a portfolio allocated to floating-rate bonds (such as senior loans) can mitigate the funding cost risk of a floating-rate loan, since rising interest rates would increase these assets' income, all things being equal. Ultimately, the decision depends on an investor’s individual situation and preferences. It may also be worth considering a mix of different tenors to reduce the risk of a drastic and unexpected rate change.
1Please note, there can be restrictions on how a loan's balance is used. For example, "non-purpose loans" such as SBLs cannot be used to invest in securities.

Important Information about Sustainable Investing Strategies: Incorporating environmental, social and governance (ESG) factors or Sustainable Investing considerations may inhibit the portfolio manager’s ability to participate in certain investment opportunities that otherwise would be consistent with its investment objective and other principal investment strategies. The returns on a portfolio consisting primarily of ESG or sustainable investments may be lower than a portfolio where such factors are not considered by the portfolio manager. Because sustainability criteria can exclude some investments, investors may not be able to take advantage of the same opportunities or market trends as investors that do not use such criteria. Companies may not necessarily meet high performance standards on all aspects of ESG or sustainable investing issues; there is also no guarantee that any company will meet expectations in connection with corporate responsibility, sustainability, and/or impact performance.
