Small-Cap Stocks Shed Their Lead as Borrowing Costs Climb
The Russell 2000 index, which tracks two thousand of the smaller publicly traded companies in the United States, has fallen 8.3% behind the S&P 500 over the trailing twelve months ending August 2026, erasing what had been a brief period of outperformance in late 2024. The reversal happened quietly, with no major news events. Here is what caused it: smaller companies borrow more money at floating rates, meaning their interest payments change when central banks adjust rates. When those rates rise, smaller companies have less money left for hiring, expansion, or paying what they owe.
Why debt structure decides the outcome
A typical company in the Russell 2000 carries between 40% and 50% of its total debt as short-term or floating-rate obligations, meaning the interest payment adjusts within months of a central bank move. A typical S&P 500 company carries less than 10%. When the Bank of Canada held its overnight rate above 4% through the first half of 2026, and the U.S. Federal Reserve kept its own policy rate in similar territory, the gap in debt service costs between small and large firms widened to levels not seen since the 2008 cycle. For a mid-sized oilfield service company in Nisku with $12 million in floating-rate debt, a two-percentage-point rate increase translates to an extra $240,000 in annual interest expense. That is three mid-level hires, or the margin on a small contract, or the difference between profit and loss in a quarter where utilization runs below 80%.
The S&P 500, by contrast, is anchored by companies that refinanced into fixed-rate debt during the 2020-2021 window, when borrowing was nearly free, and that hold cash reserves large enough to weather multiple years of elevated rates without adjusting operations. The result is a performance divergence that tracks the debt maturity calendar more closely than it tracks sector exposure or revenue growth.
The profitability problem underneath
Roughly one-third of the companies in the Russell 2000 reported negative earnings over the trailing twelve months as of mid-2026, a figure that has held stubbornly high even as the broader economy avoided recession. These are regional industrials, small banks, and service firms that generate revenue but whose operating margins cannot absorb higher debt service and still turn a profit. Analysts use the term "zombie firm" to describe a company that earns enough to pay interest on its debt but not pay back the principal amount borrowed, and whose survival depends on lenders agreeing to extend the loan terms rather than force a sale or liquidation.
When rates were near zero, extending those terms cost lenders nothing. At 4% to 5%, the opportunity cost of capital changes the conversation. A wave of maturities is scheduled for 2027 and 2028, and the companies facing those refinancing walls will be negotiating under conditions far less favourable than the ones that prevailed when the debt was originally issued.
What a rate-cut cycle changes
The Bank of Canada lowered its policy rate to 4.25% in September 2024 and has signalled further cuts through 2025 and into 2026, aiming for a neutral level somewhere between 2.5% and 3%. If that trajectory holds, smaller firms will see debt service costs stabilize and then decline, which historically precedes a recovery in small-cap relative performance by twelve to eighteen months. The lag exists because companies do not immediately reinvest savings from lower rates. They pay down debt, rebuild cash reserves, and only then resume the kind of capital spending that shows up in revenue growth.
For an investor in Edmonton holding a position in junior energy or small industrials, the timing will determine the outcome: small-caps will recover, but whether the recovery arrives before the next round of economic uncertainty does remains uncertain.
