Russell 2000 Floating-Rate Debt Service Eats 38% of EBITDA as Large-Cap Cash Buffer Insulates

Small-cap floating-rate debt service now consumes 38.2% of EBITDA (median) vs 11.4% for S&P 500, as SOFR holds near 5.25% in October 2026. Russell 2000 interest coverage has fallen to 2.8x, testing the 2020 trough, while large-cap cash buffers and fixed-rate debt keep them insulated.

🎯 THE SIGNAL

Russell 2000 relative valuation at 12.8x forward P/E vs 22.1x for S&P 500 may persist as debt service burden caps earnings growth.

📈 BULLISH VECTORS

Large-cap quality (S&P 500) with fixed-rate debt and 4.8% cash yield remains the defensive beneficiary.

📉 BEARISH VECTORS

Russell 2000 earnings face a 6-8% headwind if SOFR stays above 5% through 2027, pressuring refinancing.

⚠️ PRIMARY RISK TRIGGER: A sudden 100bp drop in SOFR would relieve pressure, but a spike would trigger downgrades and defaults.
