The SET index closed at 1,579 on June 22, 2026—up 48% over the past twelve months. The SET50 hit its highest point since early 2022 around mid-June, and foreign fund inflows have been a consistent tailwind all year. Thailand drew more than 14 million international visitors in the first five months of 2026, and that tourist money has filtered through the economy in ways that show up in bank earnings, retail consumption, and property demand.
But the backdrop is shifting. The Fed’s hawkish dot plot is now in the market, October hike expectations are building, and USD/THB is at 33.17. These factors do not kill the SET rally—but they change which sectors make sense to hold going into H2 and which ones carry hidden risks that the headline index number obscures.
Why the SET Has Outperformed
Three compounding factors have driven the twelve-month gain. First, Thailand’s tourism recovery has been better than most economists projected eighteen months ago. The combination of Chinese tourists returning and strong Western European and Middle Eastern visitor numbers created a demand surge that benefited hospitality, transport, and retail. Second, S&P’s reaffirmation of Thailand’s BBB+ rating in June created a signal for foreign institutional funds to increase Thailand allocation. Third, global capital has been rotating away from some of the highest-multiple US tech positions into emerging market value, and Thailand’s relatively low P/E ratio made it an obvious destination.
Sectors That Win Under Fed Hike Risk
Exporters: A weaker baht is a direct revenue boost for companies that bill in dollars but report in baht. Auto parts manufacturers, electronics assemblers, and agribusiness exporters see margin improvements without any operational change. This is the most mechanical SET play in the current environment.
Banking: The link between Thai bank stocks and global rate expectations is indirect but real. If the BoT eventually follows the Fed with even a single hike—not the base case, but possible by Q4—Thai banks’ net interest margins would improve. Even without a domestic hike, banks with strong dollar-revenue streams from trade finance benefit from currency moves. KBank, SCB, and Krungsri are the large-cap names to watch.
Tourism infrastructure: Airport, hotel, and aviation plays have driven much of the SET’s 48% gain and retain earnings momentum as visitor numbers continue to rise through Q3, which is typically strong for European and Middle Eastern tourists.
Sectors That Face Headwinds
Consumer discretionary and retail: Higher imported costs from baht weakness, combined with domestic consumer caution around any potential rate adjustment, weigh on discretionary spending companies with thin margins and no export revenue to offset.
Property developers with dollar debt: Companies that issued bonds in USD face a direct cost increase when the baht weakens. Any developer with significant offshore debt exposure needs to be stress-tested against a 34.00 baht scenario.
Utilities with import costs: Energy utilities that import LNG or fuel oil pay more in baht for every unit when the currency weakens. Margins compress unless they have pricing power to pass through costs.
What This Means for Thai Investors Holding SET
The 48% twelve-month gain means the SET has already priced in a lot of the recovery story. The forward P/E is no longer as cheap as it was a year ago, and global rate headwinds create a ceiling on how far multiple expansion can carry the market.
The SET is unlikely to give back all of its gains—the underlying earnings story in tourism, banking, and exports is real. But a Fed hike in October could trigger a 5–8% correction in the headline index as foreign funds reassess emerging market allocations. That kind of dip, if it comes, would historically have been a buying opportunity rather than a signal to exit.
For existing SET holders, reviewing sector weights now makes sense. Trimming consumer-facing positions that benefited from post-COVID recovery enthusiasm and tilting toward exporters and banks sets up better for the rate-hike environment that is coming.
