Correction: The headline claim 'consumer lending is shrinking' was moved to the key points because it lacks quantitative data.

2026 growth forecast 2.0% (raised from 1.8% (July 2026)); 2027 1.9% (lowered from 2.0% (July 2026)); Southeast Asia 4.7%
Inflation forecast 2.5% for 2026 (revised down from 2.9%) and 1.3% for 2027
ADB says high credit risk is shrinking consumer lending and household debt is restraining consumption

Facts

Growth: in its Asian Development Outlook September 2026, published on 23 September 2026, the Asian Development Bank (ADB) raised its 2026 growth forecast for Thailand to 2.0% ¹ (raised from 1.8% (July 2026)) and cut its 2027 forecast to 1.9% (lowered from 2.0% (July 2026)). The forecast for Southeast Asia as a whole is 4.7% for 2026 (raised from 4.6% (July 2026)) and 4.9% for 2027 (raised from 4.8% (July 2026)).

Prices and rates: Thailand's inflation forecast is 2.5% for 2026 (revised down from 2.9%) and 1.3% for 2027. The policy rate was 1.00% as of August 2026. Source: as above.

Credit: ADB noted that consumer lending is contracting amid high credit risk, that banks are offering restructuring to vulnerable borrowers, and that high household debt and tight financial conditions are restraining consumption. Source: as above.

Analysis

By comparison, Thailand's 2.0% is well below Southeast Asia's 4.7% and Vietnam's 7.8%, and similar to Myanmar's 2.2%. ADB's description indicates that consumer credit is shrinking despite a low policy rate (1.00%), suggesting that the constraint lies in borrowers' repayment capacity rather than the price of money.

The BOT's Q2 data also show contracting SME and consumer lending and continued pre-emptive restructuring (2026-08-18), consistent with ADB's assessment.

Implications

ExecutivesLenders should not read a small upgrade to growth as a recovery in household credit, and should keep assessing repayment capacity borrower by borrower.

InvestorsThai household credit is unlikely to recover on lower rates alone; the debt resolution framework (bankruptcy reform) and restructured loan trends are the points to watch.

OperatorsWith demand for credit present but supply-side underwriting tight, methods that assess repayment capacity precisely will be a differentiator.

Counterpoints and uncertainties

The upgrade reflects first-half outturns, and 2027 was revised down. ADB's forecasts depend on external assumptions (Middle East, fuel prices), with substantial downside risk. The size of the 2026 revision (raised from 1.8% (July 2026)) is arguably within forecast error.
