What Is the iShares MSCI Thailand ETF (THD)?
The iShares MSCI Thailand ETF (THD) tracks the MSCI Thailand IMI 25/50 Index, providing US-listed exposure to Thai large- and mid-cap equities listed on the Stock Exchange of Thailand (SET). Managed by BlackRock, THD is the primary vehicle for international investors seeking Thailand equity exposure, with $265.3 million in assets under management as of June 2026. The fund holds 86 securities.
Thailand's 2026 equity rally is one of the most overlooked stories in global markets: a country that lagged regional peers through 2023-2025 — weighed down by high household debt, weak domestic consumption and political instability — has surged to become the 4th best-performing country ETF in the world year-to-date. The story begins and ends with one company: Delta Electronics Thailand.

THD Performance Snapshot
| Period | THD Return |
|---|---|
| YTD (Jan 1 → June 3, 2026) | +25.10% |
| 1-Year (June 2025 → June 2026) | +38.19% |

THD's +25.10% YTD places Thailand 4th globally, behind only South Korea (EWY +120.7%), Taiwan (EWT +68.6%) and Norway (ENOR +28.9%). The 1-year return of +38.19% significantly outpaces the MSCI ACWI's +28.42% over the same period. The 3-year return of just +4.27% underscores how recent this recovery is — Thailand has compressed years of underperformance into a single strong cycle.
The Iran war period produces a near-flat result (-0.53%) — Thailand was directly impacted as an energy importer but offset that headwind through Delta Electronics' AI demand-driven outperformance.

Top Holdings and Portfolio Structure
THD's defining structural feature is the extraordinary concentration in Delta Electronics Thailand (DELTA-R.BK) — at 20.67% of fund weight, Delta alone is the most heavily-weighted single holding of any country ETF in the Southeast Asia universe.
| Holding | Ticker | Weight | Sector |
|---|---|---|---|
| Delta Electronics Thailand | DELTA-R.BK | 20.67% | Electronics / Power supply |
| Advanced Info Service | ADVANC-R.BK | 6.86% | Telecommunications |
| PTT (royalty trust) | PUTRF | 6.64% | Energy |
| CP ALL (royalty trust) | CVPUF | 4.32% | Consumer staples / retail |
| Gulf Energy | GULF-R.BK | 4.27% | Energy / power generation |
| Advanced Info Infrastructure | AIPUF | 4.14% | Telecom infrastructure |
| PTT Exploration & Production | PTTEP-R.BK | 3.56% | Oil & gas exploration |
| Bangkok Dusit Medical | BDUUF | 3.52% | Healthcare |
| SCG Packaging | SCVUF | 3.21% | Industrials |
Delta Electronics Thailand at 20.67% is the fund's entire thesis. Delta manufactures power supplies, UPS systems, industrial automation components and thermal management systems for data centres. As AI data centre build-out has accelerated — Microsoft, Google, Amazon and Meta collectively committing $720 billion in AI capex in 2026 — Delta's data centre power and cooling products have experienced demand conditions unlike anything in the company's history. Delta Electronics Thailand is a subsidiary of Delta Electronics (Taiwan), one of the world's largest power electronics manufacturers, and benefits directly from the same AI infrastructure spending wave that is driving TSMC and SK Hynix.
Market Drivers
Delta Electronics: The AI Power Play. Every hyperscaler AI data centre consumes enormous amounts of power — and that power must be converted, conditioned, distributed and regulated within the facility. Delta's server power supplies, rack PDUs (power distribution units), UPS systems and precision cooling units are essential components in every major data centre globally. The company's order backlog has expanded dramatically as data centre construction accelerated. Q1 2026 earnings showed Delta's data centre segment growing at a rate that has driven the stock to all-time highs.
Thailand's energy transition investments. Gulf Energy Development (4.27% of THD) and GULF's infrastructure pipeline are benefitting from Thailand's energy transition programme and the country's expanding power generation capacity — itself partly driven by the need to power new data centres. The energy sector's 10%+ weight in THD provides a complementary driver to Delta's electronics story.
Tourism and domestic recovery. Thailand received approximately 35 million international visitors in 2025, approaching but not yet restoring pre-pandemic levels (39.8 million in 2019). Reuters noted (April 2026) that the Iran war initially caused a foreign investor pullback, but SET Q1 2026 earnings — reported in late May — "fuel hopes of a revival" according to Bangkok Post. The domestic consumption component of the Thai equity market — CP ALL convenience stores, Bangkok Dusit healthcare — is recovering as real wages improve and tourism flows return.
Political stabilisation. After years of political instability (coup in 2014, prolonged military-influenced governance, contested elections), Thailand's political environment under Prime Minister Anutin Charnvirakul has stabilised sufficiently to allow institutional capital to return. This normalisation — not yet celebrated, but present — removes a discount that had weighed on Thai equity valuations for years.
Valuation
Thailand at 18.25x forward P/E trades essentially at parity with the MSCI ACWI (18.23x) — a remarkable position for a market that was historically discounted as a frontier/lower-tier emerging market.
| Market | ETF | Fwd P/E | vs ACWI |
|---|---|---|---|
| Taiwan | EWT | 22.71x | +24.6% |
| Thailand | THD | 18.25x | +0.1% |
| MSCI ACWI | ACWI | 18.23x | — |
| Japan | EWJ | 17.50x | -4.0% |
| South Korea | EWY | 8.35x | -54.2% |
| India | INDA | 20.06x | +10.1% |
Thailand's near-parity valuation with the global benchmark is a function of Delta Electronics' AI premium multiple dragging the national index upward. Without Delta, Thailand's market would trade at a significant discount to ACWI — consistent with its development status and economic fundamentals. This creates a structural similarity to EWN: the country's valuation is carried by one AI-adjacent holding.
Seasonality Patterns
THD's seasonality data reveals two important signals for H2 2026:
| Month | Avg Return | Win Rate | 2026 Actual |
|---|---|---|---|
| January | +1.02% | 61% | +5.85% |
| February | +1.35% | 67% | +18.83% ← Delta surge |
| March | +0.77% | 58% | -8.19% ← Iran war |
| April | +1.81% | 53% | +2.92% |
| May | -0.35% | 32% | +1.32% |
| June | -1.95% | 37% | — |
| July | +1.62% | 67% | — |
| August | +0.34% | 44% | — |
Two structural warnings: May averages -0.35% with only 32% win rate — THD's weakest month by win rate — and June averages -1.95% with just 37% win rate. The fund is entering its seasonally worst two-month window. February 2026's extraordinary +18.83% — more than 17 percentage points above its 20-year average — reflects the timing of Delta's most recent earnings catalyst landing in that month.
July marks the seasonal turn: +1.62% average with 67% win rate — THD's best month by win rate.
Comparable ETFs
iShares MSCI Malaysia ETF (EWM): The nearest Southeast Asian peer. Malaysia trades at a deeper discount (14.09x forward P/E vs THD's 18.25x) and has returned +4.9% YTD. Both are ASEAN markets with energy and financial exposure, but Malaysia lacks Thailand's AI electronics anchor stock. EWM-THD correlation: not directly available but structural similarity is high.
iShares MSCI Indonesia ETF (EIDO): The contrasting ASEAN case — EIDO is down -31.4% YTD, driven by political risk and rupiah collapse. The ASEAN region is internally highly divergent in 2026: Thailand surging on AI electronics, Indonesia collapsing on political and fiscal risk. The THD-EIDO divergence (-56 percentage points YTD) is one of the largest intra-regional performance gaps in any geographic bloc.
iShares MSCI India ETF (INDA): The most striking contrast in emerging Asia. INDA is down -11.1% YTD while THD is up +25.1% — a 36-percentage-point divergence within the same broad geographic universe, explored in depth in the THD vs INDA comparison article.
Key Risks
Delta Electronics concentration. At 20.67% of the fund, a single guidance miss from Delta would produce an immediate 4-6% decline in THD. The company's AI data centre order book, while strong, depends on sustained hyperscaler capex commitments. Any deceleration in data centre construction spending would affect Delta before it reaches TSMC or SK Hynix in the supply chain.
Energy import vulnerability. Thailand imports approximately 60-70% of its energy. The Iran war demonstrated the direct channel: THD fell -8.19% in March 2026 as Hormuz blockade drove oil prices higher. Any renewed energy shock would replay this dynamic.
June-July seasonality. June averages -1.95% with only 37% win rate — the fund is entering its most consistently negative seasonal window. The combination of Delta's post-earnings consolidation risk and the seasonal headwind creates a near-term risk period before the July (+1.62%, 67% win rate) recovery pattern historically reasserts.
Thai baht exposure. THD holds baht-denominated assets. USD strengthening against the baht would reduce USD-denominated returns independent of underlying equity performance.
Bottom Line
The iShares MSCI Thailand ETF (THD) is the surprise outperformer of 2026 — a market that spent three years in the bottom tier of global equity performance before Delta Electronics' AI electronics exposure launched it into the global top five. At 18.25x forward P/E, Thailand is no longer cheap — the Delta premium has compressed the value discount entirely.
The investment case going forward is binary: if Delta continues to deliver AI data centre electronics demand through H2 2026, THD sustains its elevated valuation and potentially re-rates higher. If Delta's order book shows any deceleration, the concentration risk means the fund has limited diversification buffer. July's historically strong seasonality provides the next positive window after the June headwind passes.

Frequently Asked Questions
Why is Thailand's THD ETF up +25% year-to-date in 2026?
THD's rally is overwhelmingly driven by Delta Electronics Thailand (DELTA-R.BK) at 20.67% of fund weight. Delta manufactures server power supplies, UPS systems and data centre cooling products — all of which are experiencing extraordinary demand as hyperscalers accelerate AI data centre construction globally. Delta's data centre segment benefited from the same $720 billion in AI infrastructure capex driving TSMC and SK Hynix, making it Thailand's primary connection to the AI hardware supercycle. February 2026 alone delivered +18.83% for THD, driven by Delta's earnings release.
What is Delta Electronics Thailand and why does it matter?
Delta Electronics Thailand is a subsidiary of Delta Electronics (Taiwan), one of the world's largest power electronics manufacturers. It produces the power conversion, UPS and thermal management systems that are essential components in every major AI data centre. As AI compute facilities have grown from megawatts to gigawatts of power consumption, Delta's addressable market has expanded proportionally. The company's dominance in server power supplies and rack PDUs for hyperscalers has made it a direct beneficiary of the global AI infrastructure buildout — and at 20.67% of THD, its performance drives the entire fund.
What is the biggest near-term risk for THD?
June is THD's statistically worst month — averaging -1.95% with only 37% win rate over 18 years of data. Combined with the concentration risk from Delta Electronics (a single earnings guidance miss would move the fund 4-6%), the near-term window is the fund's most vulnerable seasonal period. The structural recovery signal historically arrives in July, which averages +1.62% with 67% win rate. For medium-term holders, the June headwind is a tactical risk rather than a structural concern.
