The $1.4T IG Maturity Wall: Investment-Grade Credit Refinances Into a 5.4% Yield Trap

2026-11-01, FP360 — Investment-grade corporate bond investors face a $1.4 trillion refinancing cliff over the next 18 months, with 42% of maturing debt locked in at pre-2022 coupons averaging 3.1% now rolling into 5.4% yields. The gap will compress issuer interest-coverage ratios by an estimated 210 basis points, forcing a structural repricing of IG spreads that has already widened the Bloomberg US Corporate Index OAS to 118 bps from 92 bps in September.

The Signal: IG credit spreads will grind wider through Q1 2027 as the maturity wall collides with a still-inverted 2s10s curve, squeezing issuers that waited for a rate cut that never came.
