The SET closed at 1,615 on July 11, recovering from a 1,577 low hit on July 8 during the spike in Hormuz-related oil prices. The intraday range on July 11 was 1,612–1,621, suggesting the index has found some footing. But at 1,615, Thailand is still underperforming its ASEAN neighbours — Jakarta’s JCI and Vietnam’s VN-Index have both outpaced the SET year-to-date — and the reasons for that underperformance are not going away overnight.
Why Thailand Keeps Lagging
Three structural factors explain the SET’s persistent discount to regional peers. First, the Bank of Thailand’s 1.00% rate cap on returns from baht-denominated assets means foreign investors face a double headwind: low domestic yields and a weakening currency. The baht is down 4.9% against the dollar this year. Second, Thailand’s GDP growth of 2.3% forecast for 2026 — while respectable — trails Indonesia’s 5%+ and Vietnam’s near-6% pace. Investors chasing ASEAN growth have more obvious places to put capital. Third, the SET’s sectoral composition is heavier in energy and banks, which are facing different pressures: energy from OPEC+’s output increase pulling Brent from $76.56, banks from a rate environment that does not deliver the margin expansion seen in higher-rate markets.
What the Recovery from 1,577 Means
The bounce from 1,577 to 1,615 in three sessions is real and worth noting. It happened on improving foreign inflow data — overseas investors have turned net buyers of Thai equities in July after several quarters of selling. That is the most constructive development for the SET in months. But a 38-point bounce from a July panic low does not make the structural underperformance story go away. Watch whether foreign inflows continue into the week of July 14, or whether the buying was tactical profit-taking on short positions.
Sectors That Could Lead in H2
If the SET is going to narrow the gap with ASEAN peers in H2, it will likely come from two areas. Banking is the first: KBank, SCB, and Krungsri all report Q2 earnings in the coming weeks, and net interest margins have held up better than expected at 1.00% BoT rates. A modest earnings beat from even one major bank could spark broader buying. Technology and electronics is the second area — Thailand is benefiting from supply chain shifts tied to the US-China trade restructuring, and several Thai tech-exposed companies have quietly posted strong top-line numbers in H1.
What This Means for Thai Investors
For retail investors in SET-tracking ETFs or index funds, the current level of 1,615 is within striking distance of analyst consensus targets of 1,630–1,650 for end-of-July. That is a 1–2% move, not transformative but real. The risk to that call is the Fed’s July 29 meeting: a hawkish outcome would likely reverse the foreign inflow trend and send the SET back toward 1,577 or lower.
For stock-pickers, the upcoming Q2 earnings season is the catalyst to watch. Companies in banking and tech-adjacent sectors with conservative H1 guidance are the most likely sources of positive surprises. Energy sector results will be more mixed given oil price volatility.
The Level to Watch
1,600 is the tactical line. The SET has failed to sustain closes above 1,600 several times this year. A clean weekly close above it, backed by foreign buying, would signal something is actually changing. Below 1,580, the recovery thesis needs reassessment. At 1,615 heading into the week of July 14, the market is in a better place than it was on July 8 — but it has not yet proven anything lasting.
