Thailand’s household debt problem is again moving to the centre of the economic debate as Bangkok prepares to host the IMF and World Bank annual meetings. Household debt stood at 85.2% of GDP at the end of June, while average household debt has reached its highest level in 18 years, constraining consumption and making it harder for the economy to return to its estimated potential growth rate.
Key points
- Household debt stood at 85.2% of GDP at the end of June, one of Asia’s highest ratios.
- Only about 5 million of Thailand’s 27 million borrowers are considered financially healthy enough to obtain additional credit.
- Buy-now-pay-later accounts increased from 620,000 in 2021 to 6.3 million in 2025, with outstanding loans rising to THB40.7 billion.
The headline debt-to-GDP ratio has fallen from higher levels, but policymakers caution that this does not necessarily mean household finances have improved. Tighter bank lending has limited new borrowing, while households continue to rely on consumption loans and alternative sources of credit. The result is what analysts describe as constraint-driven deleveraging rather than a healthy reduction in indebtedness.
The Bank of Thailand estimates that high household debt could prevent the economy from returning to its 2.7% potential growth rate. The problem is particularly important for Thailand because household consumption remains a relatively weak component of the recovery. When a large share of household income goes toward debt servicing, there is less capacity for discretionary spending, housing purchases and investment in education and skills.
The latest consumer-confidence data reinforce the concern. The University of the Thai Chamber of Commerce reported that confidence fell to 52.1 in September, the first decline in four months, as floods, higher living costs and diesel prices above THB40 per litre weighed on households. UTCC estimates that flooding has already caused THB22–30 billion in economic damage and maintains its 2026 growth forecast at 2.2–2.5%.
The government wants to lift growth toward 3% by attracting foreign investment into sectors such as semiconductors, but that strategy will not quickly solve the household balance-sheet problem. Sustainable improvement requires stronger income growth, better employment opportunities and restructuring of distressed debt. The IMF has also warned that excessive household debt can constrain investment in human capital and impede structural transformation.
Why it matters: Thailand’s debt problem is becoming a structural ceiling on domestic demand. Lower interest rates can provide some relief, but monetary policy alone cannot restore household purchasing power while incomes remain weak and access to productive credit is constrained.
