Oil Shock and Stagflation Risk Could Shrink Thailand’s Property Market — What Buyers Must Do Now

Thailand’s real estate market faces a new test: stagflation and rising input costs

The outlook for real estate Thailand moved from a steady-but-slow recovery to a far murkier picture after the recent escalation in the Middle East. The National Economic and Social Development Council (NESDC) has replaced a single 2026 forecast with four scenarios that range from manageable disruption to a deep economic contraction. For property buyers, investors and developers, the key question is simple: how do you preserve capital and liquidity when inflation rises at the same time economic growth stalls?

We’ve reviewed the NESDC assessment, comments from the Finance Ministry and private-sector analysis to map the implications for housing prices, construction margins, mortgage lending and foreign demand. My conclusion: the next 12–18 months will reward discipline, flexibility and a focus on completed inventory rather than speculative launches.

What the NESDC scenarios mean for the housing market

The NESDC updated its 2026 outlook after a prolonged conflict and a shutdown of the Strait of Hormuz for more than a month. The original baseline was 2% GDP growth for 2026 with average crude oil at US$58–68 per barrel and inflation around 0.2%. That baseline is gone. The council now outlines four scenarios:

• A supply shock that pushes energy prices up, disrupts supply chains and weakens the baht.
• A stagflation outcome with 0.9% GDP growth and 4.4% inflation in 2026.
• A protracted regional war lasting six to nine months with average crude at US$135–145 per barrel, cutting Thailand’s growth to 0.2% and pushing inflation to 5.8%.
• An even larger, worldwide conflict involving major powers, where standard forecasting becomes impossible.

Practical takeaway: stagflation is now a central risk for Thailand’s property market. If the economy is stuck on low or zero growth while consumer prices climb, local demand for housing—especially mortgaged purchases—will suffer.

Construction costs, developer margins and presales: the immediate shocks

Michael Kenner of FazWaz and LIFULL Connect has laid out the mechanics: higher oil prices feed through into the price of steel, cement, plastics and transportation. Developers are seeing input costs rise while buyers face weaker purchasing power and banks tighten loan standards. The result is a squeeze on developer margins and a higher chance that off-plan projects will be delayed or repriced.

Observed impacts and facts from the assessments:

• Construction input costs are rising sharply because fuel-related production and transport costs increase prices for steel, cement and plastic raw materials.
• Banks will tighten lending criteria, leading to higher mortgage rejection rates for domestic buyers.
• Air travel costs show the pass-through effect: AirAsia fares rose 40% as fuel prices jumped.

For developers this means:

• Selling completed, ready-to-move-in inventory reduces price-risk compared with long-duration off-plan projects.
• Presale volumes could shrink because domestic buyers face affordability stress and tighter mortgage underwriting.
• Cash-flow and credit management become the top priorities; projects that relied on steady presales to fund construction are the most vulnerable.

From an investor perspective, rising construction costs and uncertain pricing mean cap-rate compression may reverse. If rents do not keep pace with inflation, real yields will fall and vacancy risk can rise.

Demand-side shifts: domestic buyers, mortgages and the role of foreign purchasers

The NESDC and the Finance Ministry both warn that stagflation will reduce consumer demand. A few points to consider:

• When inflation rises while growth stalls, real incomes fall. That cuts into mortgage affordability and reduces buyer confidence.
• The Finance Ministry notes Thailand’s low baseline inflation gives the country some buffer, but the protection is limited if oil prices remain elevated.
• Banks are likely to tighten Loan-To-Value ratios and require stronger credit histories.

This is why Kenner recommends a strategic pivot to foreign buyers. From our reporting and market contacts, foreigners can play a stabilising role in several ways:

• Foreign buyers often pay larger deposits or buy in cash, reducing developers’ reliance on local mortgage markets.
• Long-stay expatriates and some regional investors view Thai property as a partial hedge against trouble at home, keeping demand for condos and resort properties.

But foreign demand is not a panacea. Travel restrictions, visa rules, currency volatility and international investor sentiment can swing quickly. Developers who chase foreigners without a realistic sales funnel risk overstretching marketing budgets.

What buyers and investors should do now: a practical checklist

If you are buying or investing in Thai property today, consider these steps based on the NESDC scenarios and expert advice:

• Prioritise completed units or projects with short completion timelines. Ready inventory avoids repricing risk from rising materials costs.
• Stress-test affordability: assume higher inflation and tighter mortgage terms when modelling cash flows and holding costs.
• Watch currency risk. A depreciating baht raises foreign-denominated returns for offshore buyers but increases costs for import-dependent construction and services.
• Demand transparent contracts. For off-plan purchases, insist on escalation clauses, escrow arrangements or other protections that define how cost increases are handled.
• Check developer balance sheets. Firms with strong liquidity and low leverage are better able to weather presale slowdowns.
• Use data and proptech. Sellers who reach global buyers efficiently will find pockets of demand even when local demand softens.

These actions are not novel.
