Third Quarter 2026: The Spectre of Higher Bond Yields
The third quarter of 2026 was marked by a growing disconnect between stock and bond investors. While U.S. equities continued their advance, Treasury bonds endured their most challenging quarter since 2022 as yields rose sharply. By late September, the benchmark 10-year Treasury yield climbed above 5%, reflecting concerns about persistent inflation, elevated energy prices, strong economic growth, expanding federal deficits, and the significant amount of new government debt being issued.
Ordinarily, such a rise in interest rates would create meaningful headwinds for stock indices. Higher rates increase borrowing costs and reduce the value investors place on future earnings. Yet stocks largely shrugged off those concerns.
The reason was simple: earnings. Corporate America continued to deliver exceptional results. Resilient consumers and continued investment in artificial intelligence infrastructure helped fuel another quarter of robust earnings growth. For now, profits are keeping stocks near all-time highs, despite higher bond yields.
Despite another positive quarter in the stock market, there are signs of turbulence beneath the surface. Consumer discretionary, utilities, and industrials stocks lagged as investors reassessed the implications of higher interest rates and persistent inflation. Meanwhile, Treasury bonds now offer income levels not seen in years, providing competition for stocks in investors’ allocation decisions.
As we enter the final quarter of the year, investors are navigating an environment that looks very different from the one many expected in January. Rather than falling interest rates and slowing growth, markets have been forced to adapt to a stronger economy, higher bond yields, and robust corporate earnings. Analysts expect earnings growth to remain strong in 2027, with earnings forecasts exceeding 15% growth for the S&P 500. Whether corporate America can deliver on those lofty expectations remains to be seen.
