Key points

Implications for lenders

With the average indebted household already paying 26.3% of income in debt service, and 40.1% in the lowest income band, underwriting that checks actual cash flow rather than income alone may help avoid lending into deficit. Because about 23.8% of indebted households already run a negative cash margin, and a rise in cash spending could lift that to 36.0%, lenders may want to plan collections capacity and restructuring options for lower-income portfolios.

Implications

ExecutivesFalling debt-to-GDP does not mean deleveraging; lower-income borrowers remain stretched while unsecured credit contracts.
InvestorsThai consumer-lending growth is concentrated in secured and higher-income segments, which shapes where loan books can grow.
OperatorsCash-flow checks matter more than headline ratios: a small rise in household spending sharply raises the share of households in deficit.

Facts

Ratio and balance: KResearch, the research arm of Kasikornbank, reported on 12 October that Thai household debt stood at 85.2% 1 of GDP at the end of the second quarter of 2026, down from 86.0% in Q1 2026. Reuters reported the same end-June ratio on 8 October. The outstanding balance was about THB 16.4 trn 2; it grew 0.6% 3 from a year earlier, the latest reading, after the balance turned up again over the past three quarters. The Bank of Thailand first published the first-quarter ratio at 85.9% 4.

Where the growth is: KResearch says home loans (especially for second-hand houses and condominiums, mainly to the highest income band), loans secured on property or other assets, and borrowing from savings cooperatives and pawnshops grew, while hire-purchase, occupational, education and unsecured loans shrank year on year. It expects the ratio to fall to about 84.0% 5 by the end of 2026.

Repayment burden: using the National Statistical Office's 2025 Household Socio-Economic Survey, KResearch calculates an average debt service ratio of 26.3% 6 for indebted households and 40.1% 7 for those in the lowest income band. About about 23.8% 8 of indebted households have a negative cash margin, rising to 48.8% 9 in the lowest income band and falling to 7.1% 10 in the highest income band. In KResearch's stress test, where households' cash spending rises, the share would reach 36.0% 11, about 1.2 million more households than the baseline.

Analysis

Time series: the ratio fell from 85.9% at first release for the first quarter to 85.2% in the second, yet the debt balance grew 0.6%. The decline in the ratio therefore comes from nominal GDP growing faster than debt, not from households paying debt down. The BIS measure in the chart, which covers credit to households from all sectors on a different basis, has also trended down since 2024.

Mix: the growth sits in secured and higher-income lending (home loans, asset-backed loans, cooperatives, pawnshops), while unsecured, hire-purchase and occupational loans shrink. The shrinking loan types are ones lower-income borrowers often rely on, even as their repayment burden stays high.

Cross-country: Malaysia's household debt was 84.8% 12 of GDP at end-2025, a similar level, and Bank Negara Malaysia puts the median debt service ratio of household borrowers at 32.1% 13. The two burden figures are not like for like: Malaysia's is a median from BNM's micro-level data, Thailand's an average across indebted households from a survey.

Counterpoints and uncertainties

The quarterly ratio and balance may be revised, as the first-quarter ratio was. The repayment-burden figures come from a 2025 survey and do not reflect the September–October 2026 floods or this year's price changes. KResearch's end-2026 forecast depends on nominal GDP growth; slower growth would stop the ratio falling even if debt stays flat. Survey responses may also under-report informal borrowing.
