Thai household debt is at its highest in 18 years, at 85.2% of GDP at end-June, and the Bank of Thailand says growth may stay around 2.3% this year against 2.7% potential. Household strain means weaker consumer spending and tighter lending. The BoT is now supervising buy-now-pay-later, whose accounts rose from 0.62 million in 2021 to 6.3 million in 2025. For a small business, plan for slower customer demand, and check your own cash flow and any personal guarantees before taking on new debt.
