Why Banks Now Treat Small Businesses as Structured Credit

Executive Summary

The era of relationship banking for SMEs is structurally over. Driven by the full implementation of Basel 3.1 in 2025–2026, global banks have reclassified SMEs from "clients" to "portfolio buckets" to facilitate securitisation. Our analysis indicates that regulatory pressure to minimize Risk-Weighted Assets (RWA) has forced banks to adopt an "originate-to-distribute" model. SMEs that cannot be algorithmically standardized for sale to credit investors now face a binary outcome: automated rejection or punitive pricing.

SME Risk Weight
85% – 100%
Up from ~57% pre-Basel 3.1 in UK/EU, drastically increasing capital cost.
Capital Charge Gap
3.5x
A bank holds ~3.5x more capital for an SME loan than a mortgage.
Auto-Decline Rate
>40%
For SMEs lacking API-ready accounting data (Est. 2026).

Diagnostic Analysis

The "Computer Says No" phenomenon is a regulatory compliance success. Mechanisms like the RWA Trap and Securitisation Exits mean that if your business cannot be digitized into a standardized data row, it is no longer profitable for a Tier 1 bank to hold you.
