The SET opened August 18 at 1,626.26, with an intraday high of 1,630.87 and a low of 1,617.37. Those numbers tell you exactly where the Thai market is: at the top of its recent range, not breaking through it. Resistance at 1,625–1,630 has held since early August. Support at 1,600–1,610 has held just as firmly. The market is compressing, and the catalyst for the next move has not shown up yet.
What Q2 Earnings Actually Showed
Most listed Thai companies reporting Q2 results surprised to the upside. The standout sectors: energy (benefiting from elevated oil prices tied to Middle East uncertainty), banking (net interest income held up despite BOT’s rate cut to 1%), and tourism-related consumer plays (visitor numbers recovering toward 2024 levels).
The weak spots: export-oriented manufacturers facing baht strength and soft global demand, and property developers navigating the aftermath of stricter mortgage qualification standards introduced in late 2025. Technology companies were mixed.
For the SET as a whole, the Q2 earnings season suggests that the 1,600 support level is genuinely supported by fundamentals — not just technical trading patterns. That matters for how you read any pullback to that level.
Foreign Investor Behavior in August
Foreign investors have been net sellers on the SET through much of 2026, with cumulative outflows exceeding 77 billion baht by mid-August. The selling pressure has moderated in August compared to June and July, but it has not reversed. Global risk-off from the Iran conflict has kept foreign money cautious toward all emerging market equities, not just Thailand.
Domestic institutions and retail investors have been absorbing the foreign selling, which is why the SET has held 1,600 rather than breaking below it. When domestic buyers are the marginal buyer, rallies tend to be slower but more durable — there is less hot money to reverse the move.
Sectors Worth Watching Now
Banking: KBank (KBANK), SCB, Krungsri, and Bangkok Bank all reported solid Q2 results. With BOT’s rate at 1%, net interest margins have been pressured but fee income and loan growth have compensated. Banking stocks are historically the first sector foreign investors return to when Thailand re-rates upward.
Energy: PTT and its listed subsidiaries (PTTEP, IRPC) have been the SET’s strongest performers in August, directly linked to elevated oil prices. If the Iran situation de-escalates, energy stocks will give back some of those gains fast.
Tourism: AOT (Airports of Thailand) is a useful proxy for the sector. August tourist numbers will be reported in September, and early data suggests continued improvement. A clean beat on visitor statistics could push AOT shares above their recent range.
The BOT Factor
The Bank of Thailand’s rate at 1% is the lowest since September 2022. Low rates help corporate earnings (lower financing costs) and make equities relatively more attractive than deposits. But the BOT has signaled it is not cutting further — so the stimulus from the rate cycle is largely priced in. The next meaningful BOT move could be a hike, not a cut, depending on what the Fed does in September-October.
Technical Levels and What They Mean
Resistance: 1,625–1,630. Three failed attempts to close above 1,630 since August 5. A daily close above 1,630 on high volume would be a genuine breakout signal.
Support: 1,600–1,610. Multiple tests, all held. A close below 1,600 would be the first since July and would likely trigger stop-loss selling from domestic retail positions.
Watch: 1,650. The level the SET needs to reclaim to suggest the market is returning to its pre-Iran-conflict range. At current pace, that is a late Q3 or Q4 story.
What Thai Investors Should Do
If you are underweight Thai equities, the current level offers an entry with a defined support floor at 1,600. The upside to 1,650 in the next two to three months is plausible if foreign selling moderates and the Fed does not hike in September. If the Fed does hike, the SET support at 1,600 will be tested seriously.
