The Core Problem
The Bank of Thailand cut its policy rate to a historic low of 1.00% in February 2026 — and SME credit contracted further.
Cheap money was never the constraint.
Every baht of SME lending costs Thai banks 9.5–13.5% to extend against a portfolio yield of 8–10% —
a mid-point cost of 11.5% against a mid-point yield of 9%.
The implied loss is structural, embedded in four cost layers no rate cut can dissolve.
Cost Decomposition

Small-ticket loans carry the same fixed cost as large ones — per-baht cost is highest for SMEs.

The Scale
Asia-Pacific holds 46% of the global $5.7 trillion MSME financing gap — against 46% of global GDP.
In ASEAN, SMEs account for 97–99% of all registered enterprises, contribute 45% of regional GDP, and employ 85% of the labor force.
They are the most productive cohort in these economies — and they are locked out of formal capital, market by market.

The Paradox
Across every ASEAN market, SME credit share has stagnated or contracted while total bank lending grew.
In Indonesia, MSME credit fell −0.06% YoY in February 2026 while total credit expanded 9.37% — the sharpest divergence in recent history.
Banks have capital. They lack the data infrastructure to deploy it to SMEs at a positive spread.

The Root Cause
Without audited financial statements, no bank can underwrite — and no SME can access formal capital at any price.
The CPA-to-SME ratio is the single most underreported indicator of structural credit inaccessibility.
Every country in ASEAN sits in the critical zone. Developed-market benchmark is 8–12 CPAs per 1,000 SMEs.
Technology-enabled accounting infrastructure is not optional. It is the prerequisite.
