SMB Credit Defaults: What the 2026 Vintage Is Telling Us

Twelve-month default rates on 2026 originations are tracking 80 bps below the 2023 vintage at the same seasoning point, with the largest improvement in services and B2B.

By Summit Underwriting DeskNew York · London

Default behavior on small-business credit originated in the first half of 2026 has been materially better than the 2023 vintage at the same seasoning point. Across the portfolio we monitor, twelve-month early-default rates are running at roughly 4.6%, compared to 5.4% for the 2023 cohort.

The improvement is not evenly distributed. Services and B2B verticals are leading the recovery, with default rates inside historical norms. Restaurants, brick-and-mortar retail, and long-haul trucking continue to print elevated default behavior — though even those segments are stabilizing relative to mid-2024.

Underwriting implications

Stronger early-default performance is encouraging more aggressive box expansion among the funders we work with. We are seeing renewed appetite for slightly thinner files — for example, 10-month time-in-business minimums where the prior standard was 12.

Funders are not loosening on cash flow. Daily debit ratio thresholds, NSF tolerance, and stacking detection remain tight. The recovery is in time-in-business and credit tolerance, not in revenue quality.
