Bank of Thailand aims for about THB 100 bn a year in new SME loans via a bank-funded guarantee

Implications for lenders

Lenders to Thai SMEs may be able to price new loans against a shared-risk guarantee instead of collateral, but with an SME NPL ratio of 9.5% underwriting discipline still matters. Free bureau checks can bring more borrower disputes over records, so data-quality and complaint-handling processes may need capacity before they start. Lenders joining the December portal may need to compete on decision speed for the same applicants.

Implications

Facts

Guarantee: speaking at the Thailand Economic Outlook 2027 forum in Bangkok on 8 October, Bank of Thailand (BOT) Governor Vitai Ratanakorn said the Credit Boost guarantee will become a permanent five-year framework by early 2027. It shares lending risk using funds redirected from commercial banks' contributions to the Financial Institutions Development Fund, so no state budget money is used. If the plan succeeds, he said, it aims to generate about THB 100 bn a year ¹ in new SME bank lending. Sources: The Nation (8 October), Fintech News Singapore (9 October).

Data and access: a rule letting individuals check their credit-bureau records free of charge twice a year is expected to take effect within two to three months. The SME credit portal, which connects businesses with several lenders, is scheduled to launch in December 2026 and to expand in the first quarter of 2027. An alternative-data exchange pooling government, utility and bank transaction records through the National Digital ID and the ITMX interbank network is due between mid- and late 2027; it is meant to help freelancers and online sellers without payslips show repayment capacity.

Credit quality: the Governor put the SME non-performing loan ratio at 9.5% ², vs about 2% for large corporates. SME lending has contracted for 16 consecutive quarters ³. He said credit is "not a universal panacea" and that some struggling firms need to change their business models.

Analysis

Over time, SME credit has lagged the rest of the loan book. Commercial bank loans grew 2.0% ⁴ year on year in the second quarter, after falling year on year in every quarter of 2025, while SME lending was still falling at −4.6% ⁵. The SME NPL ratio cited by the Governor is more than three times the commercial banking system's 2.82% ⁶, although the two figures may not share a definition or date. That loss rate is a main reason banks ration SME credit; a guarantee that absorbs part of the loss addresses it more directly than a lower policy rate.

Across the Mekong, Vietnam has taken the price route: borrowers had drawn only about 4.5% ⁷ of the State Bank of Vietnam's preferential SME programme by end-September. Thailand's design shares risk rather than cutting rates, and pairs it with data access (free bureau checks, alternative data), which targets the information gap behind rejections rather than the cost of credit.

Counterpoints and uncertainties

The lending target is conditional on the plan succeeding, and the guarantee's coverage ratio, fees and eligible lenders have not been published. The Governor gave no period or definition for the SME NPL ratio. The alternative-data exchange is more than a year away, so near-term underwriting still relies on existing bureau data.
