VWCE is Vanguard's FTSE All-World UCITS ETF. As an Ireland-domiciled, accumulating fund with about $62 billion in its accumulating share class (as of November 2026), it is a highly efficient core equity holding tracking the FTSE All-World Index to provide broad exposure across both developed and emerging markets.
IWDA is BlackRock's iShares Core MSCI World UCITS ETF. Tracking the MSCI World Index, it offers a similar accumulating, Ireland-domiciled structure with a 0.20% Total Expense Ratio. Launched in 2009, it provides market-cap-weighted exposure strictly to developed markets and has grown to about $151 billion in assets (as of October 2026).
Indian investors are often confused between these two because both serve as single-ticker global equity foundations that are heavily driven by US mega-caps and technology stocks. Here is exactly how and where they differ under the hood, and which one makes the most sense for your portfolio.

What VWCE and IWDA have in common
- Both are heavily driven by US mega-caps and the technology sector, sharing top holdings like Apple, Microsoft, NVIDIA, Amazon, and Meta.
- Both are Ireland-domiciled Public Limited Companies (PLCs), which legally shields Indian investors from the 40% US estate tax.
- Both are accumulating funds, meaning corporate dividends are automatically reinvested internally. This deferral maximizes compound growth without creating an annual taxable event.
- Both benefit from the US-Ireland tax treaty, effectively reducing the withholding tax on US dividends from 30% to 15%.
- Both share the exact same Indian tax treatment: Short-Term Capital Gains (STCG) at your applicable slab rate if held for 24 months or less, and Long-Term Capital Gains (LTCG) at 12.5% if held for more than 24 months.
- Both are readily available on global platforms like Interactive Brokers and Paasa.
Where they differ
Index strategy and market exposure
VWCE tracks the FTSE All-World Index, capturing roughly 90% to 95% of the global investable market. It holds about 3,821 stocks (as at 30 September 2026) spanning more than 40 developed and emerging market countries.
IWDA tracks the MSCI World Index, which covers about 85% of the free-float market value in each of 23 developed countries. The fund holds about 1,250 stocks (as of October 2026). If you want emerging markets exposure alongside IWDA, you must purchase a separate fund and manually rebalance your portfolio.
Fund size and track record
IWDA was launched a full decade before VWCE. Because it has been trading since 2009, it has amassed about $151 billion in assets (as of October 2026), making it one of the most liquid ETFs available globally. VWCE is newer, launched in 2019, but its accumulating share class has scaled to about $62 billion, cementing its own status as a highly liquid core holding.
Tracking difference and tax optimization
VWCE now charges a Total Expense Ratio (TER) of 0.14% after Vanguard's July 2026 fee cut, against 0.20% for IWDA, so VWCE is the cheaper fund on paper. In 2025 IWDA returned 21.2% against 21.1% for the MSCI World net index, a tracking difference of +0.1%.
IWDA's outperformance is largely mathematical. Standard net total return indices assume a maximum 30% dividend withholding tax, but Irish-domiciled funds pay only 15% on US dividends. Combined with BlackRock's securities lending revenue, this more than offset IWDA's management fee in 2025.
Provider philosophy
BlackRock is a listed company, while Vanguard is owned by its US-domiciled funds and has a long record of cutting fees, as its July 2026 cut on VWCE shows. For this pair, index coverage and cost matter more than ownership structure.
Which should Indian investors buy?
For investors seeking a pure, set-and-forget global portfolio, VWCE is the superior structural vehicle. By naturally including emerging markets, it completely removes geographical selection bias and eliminates the transaction costs and behavioral risks of manual rebalancing. It is also now the cheaper fund, at 0.14% against 0.20%.
You should pick IWDA if you want strict, targeted exposure to developed markets only. It also offers the deep liquidity of a fund of about $151 billion.
Ultimately, do not overthink it. Because both indices are market-cap-weighted, their performance is currently dominated by the same forces. VWCE, for example, currently has about 62% in the United States (as at 30 September 2026). Picking either ETF provides a deeply diversified, tax-efficient foundation for multi-decade wealth building.
Already holding one? Should you switch?
If you already hold IWDA, do not sell it just to switch to VWCE for emerging market exposure. Selling your shares triggers a direct capital gains event in India. If you have held the ETF for 24 months or less, you will pay STCG at your slab rate. If held for more than 24 months, you will pay LTCG at 12.5%.
The theoretical benefit of switching indices will be completely wiped out by the taxes you pay on the sale and the brokerage fees required to execute the trade. If you want to transition your strategy, simply leave your existing shares alone and direct all future monthly investments into your new preferred ETF.
