Thailand Lowers 2026 Growth Outlook, Warns of Open-Ended Downside if Iran Conflict Persists

Thailand's economy is slowing amid spillovers from the U.S.-Israeli war with Iran, the Bank of Thailand said. Assistant Governor Chayawadee Chai-anant warned of deep and open-ended downside risks if the conflict continues, citing near-zero Gulf tourism in March, rising import costs due to energy dependence, and a downgraded 2026 baseline GDP forecast of 1.3% if the war ends in the second half of the year.

Key Points

  • Thailand's 2026 baseline GDP forecast was revised down to 1.3% assuming the war ends in the second half of the year; this is lower than the December forecast of 1.9% and different from the government’s February range of 1.5% to 2.5%.
  • Tourism has been hit hard by the conflict: arrivals from Gulf countries dropped to close to zero in March and Gulf tourists typically account for about 7% of Thailand's tourism spending; Malaysian arrivals are also down due to higher fuel costs.
  • Rising import costs tied to Thailand’s reliance on imported energy are squeezing the economy; policymakers had expected a positive current account of about $12 billion but this outlook is likely to be revised downward and could turn negative.

WASHINGTON, April 16 - A senior official at Thailand's central bank told Reuters that the country's economic expansion is weakening and that continued conflict linked to the U.S.-Israeli war with Iran could produce virtually unlimited downside scenarios for growth.

Assistant Governor Chayawadee Chai-anant said Thailand's high dependence on imported energy has left it particularly exposed to the fallout from the regional fighting. She described a broad downward shift across several economic indicators and highlighted tourism and import costs as primary transmission channels.

"It’s going to be the downward trend for a lot of things," Chai-anant said on the sidelines of the IMF-World Bank spring meetings in Washington. She noted that attacks from Iran had prompted the closure of regional airports and that tourism from Gulf countries fell to close to zero in March. Those visitor numbers have not fully recovered, she added, and wealthy travelers from the Gulf normally represent about 7% of total tourism spending in Thailand.

Beyond the Gulf, Thailand has also seen declines in arrivals from Malaysia. Chai-anant attributed that decrease to higher fuel costs that are deterring cross-border car travel, an effect that is easing an important growth source for the tourism sector.

Given these developments, the central bank has lowered its baseline forecast for gross domestic product growth in 2026 to 1.3% on the assumption that the war ends in the second half of this year. That projection is a reduction from the 1.9% outlook issued in December. Chai-anant also referenced a February government projection that had raised its own growth expectations into a 1.5% to 2.5% range. In the bank's baseline scenario, inflation is projected to reach 3.5%.

Chai-anant said Thailand entered the crisis in a relatively strong position, which is helping to absorb some of the shock, but she was clear that the economy remains under severe pressure. "In terms of the worst-case scenarios, there’s no limits to it. It’s that bad," she said, emphasizing the scale of possible downside if hostilities continue.

Policymakers had been expecting a positive current account of roughly $12 billion for the year, Chai-anant said, but that figure would need to be revised downward in light of the recent shocks. She did not rule out the possibility that the current account could turn negative.

On monetary policy, the bank is unlikely to move to raise interest rates unless inflation persists for longer than a year, and even then a hike would not be automatic. The bank's governor has said that increasing rates would do little to address supply-driven inflation, a constraint that shapes the central bank's response options.

Chai-anant also discussed capital flows, noting that sharp outflows from Thai equities and debt in February and March were manageable and had returned to net inflows so far in April.

Looking ahead, she said the IMF-World Bank autumn meetings, which Bangkok will host in October, will offer an opportunity to spotlight countries that have been severely impacted by the conflicts. She expressed confidence that by then the Thai economy would have established a path forward. "We can actually showcase that Asian countries are having very strong fundamentals, and are agile in terms of adaptation," she said.

Risks

  • Prolonged conflict could produce open-ended downside scenarios for Thailand's economy, with severe impacts on tourism and trade - sectors directly linked to external demand and transport costs.
  • Supply-driven inflation could persist, limiting the central bank's ability to respond with interest-rate increases and complicating monetary policy - this affects consumer prices and real incomes across the economy.
  • A downgrade of the current account from an expected $12 billion surplus to a lower figure or a deficit would increase pressure on the external balance and could affect financial markets and capital flows.
