Best South Korea ETFs for UK Investors (2026)
South Korea’s stock market is dominated by three global companies: Samsung Electronics, SK Hynix, and Hyundai. Samsung is the largest company in Korea, SK Hynix is a world leader in semiconductors, and Hyundai is the third largest car manufacturer globally. Together, Samsung and SK Hynix produce the majority of the world’s high-bandwidth memory (HBM) — the chips that power AI data centres. As of 2026, tech companies are forecast to spend more than £500 billion on AI infrastructure globally, with a meaningful share flowing directly into Korean semiconductor factories.
For UK ISA and SIPP investors, five UCITS ETFs provide access to the Korean market in a single trade. All five are ISA-eligible and listed on the London Stock Exchange. They differ significantly on fees, fund size, and platform availability. The cheapest charges 0.09% per year. The most expensive charges 0.65%. On a £10,000 investment over ten years, that gap is worth approximately £560.
The largest Korea ETF by AUM at £2,424m, with the lowest fees of any South Korea UCITS ETF available to UK investors. Available on Hargreaves Lansdown, IG, Fidelity, Trading 212, and eToro. Accumulating (dividends reinvested automatically).

How South Korea ETF fees affect your long-term returns
Even small differences in ongoing charges compound significantly over time — a critical consideration for long-term ISA and SIPP investors. The comparison below uses a £10,000 starting investment at an assumed 8% annual return.
- Annual fee on £10,000: £9
- Value after 10 years: £21,389
- Total fees paid: £90
- Annual fee on £10,000: £65
- Value after 10 years: £20,829
- Total fees paid: £650
That is approximately £560 more in your portfolio from the lower-cost fund, on an identical £10,000 starting investment, before any difference in performance.
True cost of ownership: OCF plus dividend withholding tax
The OCF is not your only cost. South Korea levies a 22% withholding tax on dividends paid to foreign investors, including UCITS ETFs. This is deducted before dividends reach the fund, so it does not appear in the OCF figure.
With Korean stocks yielding approximately 1.5%, the additional drag is around 0.33% per year. This means FLXK’s true cost of ownership is closer to 0.42% rather than the headline 0.09% — still the cheapest option, but a meaningful gap worth understanding.
| ETF | OCF | KRW withholding tax drag (est.) | Estimated total drag | Type |
|---|---|---|---|---|
| FLXK | 0.09% | ~0.33% | ~0.42% | Acc |
| XKS2 | 0.45% | ~0.33% | ~0.78% | Acc |
| HKOR | 0.50% | ~0.33% | ~0.83% | Dist |
| IKOR | 0.65% | ~0.33% | ~0.98% | Dist |
| CSKR | 0.65% | ~0.33% | ~0.98% | Acc |
WHT drag estimated from 1.5% Korean dividend yield × 22% withholding tax rate = ~0.33% annual drag. This is an approximation — actual yield varies. OCF source: justETF, March 2026.
Each South Korea ETF reviewed
The cheapest and largest South Korea UCITS ETF available to UK investors. FLXK tracks the FTSE Korea 30/18 Capped index — a rules-based index of large and mid-cap Korean equities with a Samsung concentration cap of 30% at rebalance. Dividends are reinvested automatically (accumulating), making it well-suited to ISA investors who do not need income.
At £2,424m AUM, FLXK has significantly better liquidity than the smaller funds in this comparison, which typically translates to tighter bid/ask spreads when buying and selling on the LSE.
The longest-running South Korea UCITS ETF, launched in 2005. Tracks the MSCI Korea 20/35 index and pays dividends quarterly. At 0.65% OCF, it is the most expensive fund in this comparison. Its long track record is sometimes cited as a reason to prefer it, but past performance data on Korea ETFs is available on justETF for all funds — IKOR’s tenure does not offer a meaningful informational advantage.
The accumulating version of the iShares MSCI Korea ETF. Same 0.65% OCF and same holdings as IKOR, with dividends reinvested rather than distributed. For investors who want an accumulating Korea ETF, CSKR offers broadly the same exposure as FLXK — but at a 0.56% higher annual cost for no material benefit.
The best option for UK investors who want income distributions from their South Korea ETF. HKOR pays dividends semi-annually and carries a Morningstar Silver rating. At 0.50% OCF it is cheaper than both iShares options, and it has good liquidity with £404m in assets.
Mid-priced and accumulating, but the smallest fund in this comparison at just £60m. Smaller funds typically carry wider bid/ask spreads on the LSE, which adds to your effective cost when trading. Available on HL, IG, and Fidelity, but not on Trading 212 or eToro.
Samsung, SK Hynix, and the AI memory chip supercycle
South Korea ETFs offer concentrated, low-cost access to the two companies that produce the memory chips AI data centres cannot function without. Samsung Electronics typically accounts for around 25–30% of Korea-focused ETF indices and dominates production of DRAM, NAND flash, and high-bandwidth memory (HBM). SK Hynix, at roughly 15–20% of Korean indices, was the first to mass-produce HBM3E and an early supplier of this technology to Nvidia.
The KOSPI’s strong 2025–2026 performance reflects this AI infrastructure build-out directly: when hyperscalers like Microsoft, Google, and Amazon commit to expanded data centre spending, a meaningful portion of that spend flows into Korean memory factories.
Korea ETF vs global semiconductor ETF: what’s the difference?
For investors targeting AI infrastructure exposure, a South Korea ETF and a global semiconductor ETF serve different purposes and are often complementary rather than interchangeable.
- Memory-focused: DRAM, NAND, HBM
- Samsung ~25–30% of portfolio
- SK Hynix ~15–20% of portfolio
- Also includes Hyundai, financials
- Single-country concentration risk
- Logic chips: Nvidia, TSMC, Broadcom
- Equipment makers: ASML, Applied Materials
- Memory is a smaller component
- Broader geographic diversification
- Less concentrated in any one country
A Korea ETF gives you a higher-conviction bet on memory specifically. A global semiconductor ETF spreads exposure across the full chip supply chain. Neither is a substitute for the other if your view is specifically on HBM demand.
How to buy a South Korea ETF in your UK ISA or SIPP
All five South Korea UCITS ETFs in this guide are eligible for a Stocks and Shares ISA and a Self-Invested Personal Pension (SIPP). The steps below apply to both wrappers.
Is South Korea already in your global ETF?
Whether South Korea appears in your existing portfolio depends on which index family your global ETF tracks. This is one of the most common sources of confusion for UK investors comparing FTSE and MSCI-based funds.
- Vanguard FTSE All-World (VWRP/VWRL)
- Vanguard FTSE Developed World
- Korea weight: ~1.5%
- FTSE classifies Korea as developed
- iShares Core MSCI World (SWDA/IWDA)
- Xtrackers MSCI World
- Korea weight: 0%
- MSCI classifies Korea as emerging
If you hold VWRP, you already have approximately 1.5% exposure to South Korea. If you hold SWDA, you have zero Korea exposure. Adding a Korea ETF alongside SWDA increases your allocation; adding it alongside VWRP adds a top-up above your existing 1.5%.
FTSE vs MSCI Korea: the key index differences
| Feature | FTSE Korea 30/18 | MSCI Korea 20/35 |
|---|---|---|
| Samsung concentration cap | 30% at rebalance | 35% ongoing |
| Market classification | Developed | Emerging |
| Approx. constituents | ~110 | ~90 |
| Included in FTSE All-World? | ✓ Yes | — No |
| Included in MSCI World? | — No | — No (EM index) |
| ETF tracking it (LSE) | FLXK | IKOR, CSKR, HKOR, XKS2 |
South Korea ETF performance, volatility and risks
The one-year returns shown in this guide (approximately 130–147%) reflect an unusually strong period driven by AI-related semiconductor demand. This level of performance is not typical and should not be used to set expectations for future returns.

Volatility and drawdown risk
Korean equities are inherently volatile. The KOSPI — South Korea’s main stock index — fell more than 35% in 2022 as rising interest rates hit growth stocks and global semiconductor demand contracted. In 2020, the KOSPI also fell approximately 35% during the initial Covid shock before recovering sharply. Single-country ETFs of this type can experience drawdowns that a global fund would substantially cushion.
Key risks to understand before investing
Concentration risk: Two companies — Samsung and SK Hynix — account for roughly 40–50% of most Korea ETF indices. If either underperforms significantly, the ETF follows.
Geopolitical risk: South Korea shares a border with North Korea. While markets have historically proven resilient to Korean Peninsula tensions, geopolitical escalation is a tail risk specific to this country ETF.
Currency risk: Korean ETFs are priced and traded in GBP on the LSE, but the underlying assets are denominated in Korean Won (KRW) and, for some fund operations, US dollars. GBP/KRW and GBP/USD movements affect your sterling return independently of the ETF’s local performance.
Sector concentration: The technology sector — primarily semiconductors — dominates Korean indices. A downturn in the global chip cycle, a pullback in AI infrastructure spending, or oversupply of memory chips would disproportionately affect Korea ETF holders compared to a broader global fund.
Frequently asked questions
Franklin FTSE Korea (FLXK) at 0.09% per year — the cheapest South Korea UCITS ETF available to UK investors. On a £10,000 investment that is £9 per year. The most expensive option, iShares MSCI Korea at 0.65%, costs £65 per year for a broadly similar portfolio.
Yes. Franklin FTSE Korea (FLXK) and HSBC MSCI Korea Capped (HKOR) are available on Trading 212 with no trading commission. Fractional shares are supported on both. Xtrackers MSCI Korea (XKS2) is not available on Trading 212.
Yes. All five ETFs in this comparison are UCITS-compliant and eligible for UK Stocks and Shares ISAs and SIPPs. Returns generated inside an ISA are free from UK capital gains tax and dividend tax. Note that Korean withholding tax on dividends (22%) is still deducted at source before the ETF receives income — this applies regardless of your UK wrapper.
You can purchase Samsung GDRs on the London Stock Exchange under the ticker SMSN. However, buying individual Samsung shares gives you no diversification — these Korea ETFs hold 80–100+ Korean companies across technology, industrials, financials, and consumer sectors. A single-stock position also concentrates your risk in one company’s management decisions, accounting, and competitive position.
Both index families cover large and mid-cap Korean equities with similar top holdings. The key differences: FTSE uses a Samsung concentration cap of 30% at rebalance (MSCI uses 35%); FTSE classifies Korea as a developed market (MSCI classifies it as emerging); and FTSE indices contain slightly more constituents (~110 vs ~90). In practice, the fee difference between FLXK (0.09%) and MSCI trackers (0.45–0.65%) is more meaningful to long-term returns than the index methodology difference.
High-bandwidth memory is a type of computer memory designed for very high data transfer speeds. It is a critical component in AI accelerator chips, including Nvidia’s H100 and H200 GPUs. Samsung and SK Hynix are the two largest HBM producers globally — together they supply the majority of the world’s HBM output. Strong AI infrastructure spending has been a major driver of Korean equity performance in 2025 and 2026. A slowdown in AI capex or increased competition from non-Korean memory producers would be a material risk to the thesis.
It depends on the index provider. FTSE classifies South Korea as a developed market — it is included in FTSE World and FTSE All-World indices (Vanguard funds). MSCI still classifies South Korea as an emerging market — it is excluded from the MSCI World index (iShares SWDA) but included in the MSCI Emerging Markets index. This classification difference is why VWRP holders already own Korea and SWDA holders do not.
Yes. The underlying Korean companies earn and hold Korean Won (KRW). Although LSE-listed Korea ETFs are priced in GBP, your sterling return depends on both the ETF’s local performance and GBP/KRW exchange rate movements. If the pound strengthens, your gain in sterling will be reduced even if the Korean market has risen. Some ETFs offer currency-hedged share classes, but these typically add a small extra cost.
