Thailand’s household debt crisis threatens to keep growth below potential despite lower debt ratios

Thailand's household debt crisis is resurfacing as a critical issue in the ongoing discussions at the IMF and World Bank annual meetings. Currently, household debt stands at 85.2% of GDP, marking one of the highest ratios in Asia and signaling a significant constraint on the country's potential growth. Only around 5 million out of Thailand's 27 million borrowers are deemed financially stable enough to secure more credit, indicating a substantial portion of the population remains vulnerable to rising debt burdens.

The emergence of buy-now-pay-later services has surged from 620,000 accounts in 2021 to 6.3 million in 2025, with outstanding loans ballooning to THB40.7 billion. Despite a decline in the headline debt-to-GDP ratio, policymakers remain wary, emphasizing that this reduction does not necessarily reflect an improvement in household finances.

Tighter lending practices by banks have limited new borrowing, while households continue to depend on consumption loans and alternative credit sources, leading to what experts call "constraint-driven deleveraging" rather than a genuine reduction in indebtedness.

The Bank of Thailand predicts that high household debt could hinder the economy from reaching its estimated growth potential of 2.7%. This issue is particularly salient for Thailand because consumer spending, which relies heavily on debt servicing, is a weak link in the recovery process. When a significant portion of household income is allocated to debt, there is less disposable income available for discretionary spending, housing purchases, and investments in education and skill development.

Recent consumer-confidence data support these concerns, with the University of the Thai Chamber of Commerce reporting a decline to 52.1 in September, marking the first decrease in four months, due to floods, rising living costs, and diesel prices exceeding THB40 per liter.

The University of the Thai Chamber of Commerce estimates that flooding has already inflicted THB22–30 billion in economic damage and maintains its 2026 growth forecast at 2.2–2.5%, underscoring the long-term ramifications of the debt crisis. The government aims to boost growth toward 3% by attracting foreign investment in sectors like semiconductors, yet this strategy alone is unlikely to swiftly resolve the household balance-sheet challenges.

Sustainable improvement necessitates stronger income growth, improved employment opportunities, and the restructuring of distressed debt. The International Monetary Fund has also cautioned that excessive household debt can stifle investment in human capital and hinder structural transformation, making it clear that Thailand's debt problem is emerging as a structural ceiling on domestic demand.
