Thai bank lending grew again in the second quarter of 2026, but the growth came mainly from large companies borrowing for working capital rather than from household credit. The Bank of Thailand’s quarterly banking sector brief, published 18 August 2026, put overall loan growth at 2.0% year on year, up from 0.2% in the first quarter. SME lending and the consumer loan total kept contracting, and within consumer loans the drag is the auto book: mortgage loans grew about 1.0% year on year.
For a Thai buyer counting on a bank mortgage, or a developer counting on presale buyers who need one, that split in where the credit is going is the story.
What happened
The Bank of Thailand releases a banking sector quarterly brief a few weeks after each quarter closes. The second-quarter 2026 edition, dated 18 August 2026, reports that licensed banks and their subsidiaries grew total lending 2.0% year on year, up from 0.2% in the first quarter. The central bank attributes the pickup to large corporates borrowing for working capital to absorb higher energy and raw material costs. “SMEs and consumer loans continued to contract, reflecting persistently high credit risks,” the brief states, a line it repeats in its summary, its bullet points and its section on the commercial banking system.
Consumer loans, in the Bank of Thailand’s own breakdown, are 46% mortgage loans, 31% personal loans, 15% auto loans and 8% credit card loans. In the brief’s chart of consumer loan growth by portfolio, mortgage loans grew about 1.0% year on year in the first quarter and about 1.0% again in the second. The contraction sits in the auto book, at -7.5% and then -7.0%. The panel headline above that chart reads: “Consumer loans slightly improved, particularly in auto loans and credit card loans.” The consumer total was still slightly negative in both quarters.
Confirmed figures and source dates
From the Bank of Thailand’s Banking Sector Quarterly Brief (Q2 2026), published 18 August 2026:
- Overall bank loan growth: 2.0% year on year, up from 0.2% in the first quarter of 2026
- SME lending and the consumer loan total: continued to contract, unchanged in direction from the first quarter, with auto loans the drag inside consumer credit
- Mortgage loan growth: about 1.0% year on year in the first quarter and about 1.0% again in the second, in the brief’s chart of consumer loan growth by portfolio; auto loans over the same two quarters ran at -7.5% and -7.0%
- Mortgage non-performing loan ratio (Stage 3): 3.79% in the first quarter and 3.73% in the second, the highest of the four consumer portfolios, in the brief’s chart of Stage 3 loans by portfolio
- Non-performing loans (Stage 3): ฿534.8 billion, a ratio of 2.82% of total credit, down from 2.85% at the end of the first quarter
- Stage 2 loans (loans with a significant increase in credit risk): declined to 6.78% of total loans, partly from migration into non-performing status and partly from borrowers whose credit quality improved after restructuring
- Household debt to GDP: 85.9% as of the first quarter of 2026, the latest figure the brief carries; the ratio declined, which the central bank attributes to subdued household debt growth and a higher nominal GDP base
- Household debt growth: 0.5% year on year as of the first quarter of 2026
- Mortgage35%
- Personal28%
- Business18%
- Auto8%
- Others8%
- Credit card3%
The central bank’s own note on where that debt is growing matters as much as the totals: household debt “increased slightly, driven by personal loans extended by savings cooperatives and housing loans from SFIs” — specialized financial institutions, the state-backed lenders that operate under a government mandate. The brief names no individual lender among them. Commercial banks, the brief’s charts show, are not the source of the growth.
Who is affected
Thai buyers applying for a mortgage from a commercial bank, and developers whose presale contracts depend on those buyers securing one. What household debt growth there was came from personal loans at savings cooperatives and housing loans from specialized financial institutions. On the brief’s household debt chart, commercial banks contribute negatively to total household debt growth. That chart carries no housing split, so it does not show what commercial banks did on mortgages by themselves.
Developers and contractors who rely on SME working-capital loans are affected too, though less directly for a buyer: the brief groups SME and consumer lending together as the segment that keeps contracting, against corporate loan growth of the kind large builders and hotel groups draw on.
What it may mean for Phuket property
The Bank of Thailand publishes no provincial breakdown, so what follows is inference from the national figures rather than a Phuket-specific measurement.
Phuket’s higher-value listings draw heavily on foreign buyers, most of whom do not use a Thai mortgage at all: non-resident lending from Thai banks is limited, expensive by comparison with buyers’ home markets, and rarely covers a large share of the purchase price, so most of that segment pays cash. The middle-market and off-plan segments are the ones where a purchase contract is written on the assumption that a bank mortgage clears at completion, and there the mortgage book is close to flat rather than shrinking: about 1.0% growth in both quarters, while the consumer total was pulled down by car loans. A developer selling into that segment is selling into a mortgage market that is holding its size, not expanding.
Flat is not the same as comfortable. Mortgages carry the highest non-performing loan ratio of the four consumer portfolios, 3.73% in the second quarter. Specialized financial institutions and savings cooperatives supplying the household debt growth is a signal worth watching rather than a reassurance.
What remains unknown
The mortgage figures here are read off charts. The brief labels the end points of each line but publishes no table behind them, so mortgage growth reads as about 1.0% rather than to a second decimal. Mortgage credit quality is shown: the Stage 3 non-performing loan ratio for mortgage loans was 3.73% in the second quarter, down from 3.79% in the first, and the highest of the four consumer portfolios. The brief’s own headline on that panel is that overall consumer NPLs remained stable, while personal loan and auto loan NPLs increased slightly.
Nothing in the release measures Phuket, or any province, separately from the national aggregate. How much of the contraction in SME and consumer credit reflects buyers and developers on this island specifically is not something this source can answer.
The housing loan growth at specialized financial institutions is not split by lender, so which of them is doing the lending is not stated. Whether the shift toward those institutions and savings cooperatives is a temporary gap-filling role or a lasting change in who finances Thai home purchases is also open; the brief describes the current quarter without projecting the trend forward.
