Best MSCI World ETF in 2026 : TER, AUM, live comparison of UCITS funds
Which MSCI World ETF to pick between CW8, EWLD, WPEA, DCAM or IWDA ? Live comparison (TER, AUM, PEA eligibility), overlap matrix between funds, synthetic proxy mechanism for PEA, detailed FAQ.
The MSCI World index in brief
The MSCI World tracks about 1,400 companies listed across 23 developed countries. Its market capitalization covers roughly 85% of the free-float capitalization of developed markets globally, excluding emerging markets and small caps.
Weighting is by free-float market capitalization, which mechanically gives a dominant share to the United States (around 70% in 2026) and to mega-cap technology stocks. The top 10 holdings account for roughly 25% of the index : Apple, Microsoft, NVIDIA, Amazon, Alphabet (A and C), Meta, Broadcom, Tesla, JPMorgan.
For a European investor, the MSCI World is the most common base layer of an equity portfolio : a single ETF covers the main developed economies with automatic quarterly rebalancing.

The case of PEA-eligible synthetic MSCI World ETFs
The French PEA tax wrapper requires 75% of assets to be invested in European companies. MSCI World ETFs holding direct US, Japanese or UK securities do not meet this requirement.
Issuers have therefore built synthetic ETFs : the fund holds a basket of PEA-eligible European equities, and signs a swap (performance exchange) with a counterparty that delivers the MSCI World performance. The result : the fund is legally PEA-eligible while economically tracking the MSCI World.
Practical consequence : two PEA synthetic ETFs tracking the MSCI World (CW8, DCAM, WPEA…) will have nearly 100% overlap with each other, and almost identical overlap with a CTO physical ETF (EWLD, IWDA). Our simulator resolves each synthetic to its physical proxy to compute real economic exposure.
Overlap between ETFs tracking the MSCI World
When several ETFs track the same index, their overlap is mechanically very high. The matrix below computes the real overlap from current holdings (with physical proxy resolution for PEA-eligible synthetic ETFs).
Criteria to differentiate them
When overlap between two ETFs tracking the same index exceeds 95%, the following criteria become the actual differentiators.
Listed TER and compounded cost
Total Expense Ratio is deducted yearly from the fund's assets. Over 20 years, the gap between a 0.07% and 0.38% TER represents several thousand euros on a €50,000 investment, all else being equal.
Replication method
Physical replication directly holds the index securities. Synthetic replication uses a swap : a counterparty commits to deliver the index performance. Synthetics are required to make non-EU equity ETFs eligible for the French PEA.
PEA eligibility and proxy mechanism
A PEA-eligible synthetic ETF holds European equities (to satisfy the PEA quota) and receives the target index performance via swap. To compute real overlap, our tool resolves each synthetic to its reference physical ETF tracking the same index.
AUM and liquidity
High AUM (above €500M) typically ensures tight bid/ask spreads and a low fund closure probability. Very small ETFs (below €50M) carry a liquidation risk.
Listing currency and distribution policy
An ETF listed in USD with an EUR/USD hedge has an implicit hedging cost. A distributing (D) ETF pays dividends to the cash account ; an accumulating (C) ETF reinvests them automatically. Within the French PEA the taxation is unaffected ; in a standard brokerage account distribution triggers withholding tax.
Per tax wrapper
In PEA (French tax wrapper)
Several synthetic MSCI World ETFs are PEA-eligible. Key questions : the TER, the AUM (which determines liquidity and fund durability), and the quality of the swap mechanism (the counterparty is usually the issuer's parent bank).
All these ETFs rely on a basket of European equities plus a swap, so real economic exposure remains that of the MSCI World regardless of your selection. The differentiator is mostly cost.
In a standard brokerage account
In a standard brokerage account, you can access Irish physical ETFs (IWDA, EWLD) that directly hold the index securities. These ETFs have historically been cheaper (TER around 0.20%).
The downside : distributed dividends are taxed under the relevant capital income regime, unlike PEA. To optimize, accumulating versions (acc) automatically reinvest dividends in the fund.

Ranking methodology
Global score out of 100 computed from 7 weighted criteria, aggregated from the ETF Overlap live database. Synthetic and physical ETFs are scored on the same grid.
- TER (30%) : lower is better, normalized on the range observed for this index.
- AUM (25%) : assets under management, log scale to avoid crushing mid-sized ETFs.
- Track record (10%) : number of years since launch, normalized.
- Share price (10%) : lower is better. A low unit price (e.g. €5 for WPEA vs €640 for CW8) makes regular investments (DCA) easier and reduces order rounding friction.
- 1Y performance vs peers (10%) : 12-month gross performance ranked across all ETFs tracking the same index. Top performer scores 100, lowest scores 0. Computed from closing prices in our base.
- Replication vs index (10%) : distance to the pool median performance, used as a proxy for the index return. An ETF whose return drifts significantly above or below the median reflects looser replication (hedging, aggressive sampling, hidden costs). 100 = on median, 0 = maximum observed deviation.
- Accumulating vs distributing (5%) : 100 for accumulating ETFs (acc), 0 for distributing (dist). Accumulating reinvests dividends automatically and avoids annual dividend taxation in standard brokerage accounts.
This ranking is a multi-criteria synthesis, not a personalized recommendation. It depends on the freshness of AUM, TER, price and performance data in our base.
Frequently asked questions
Which is the best MSCI World ETF for a French PEA ?
There is no universal ranking : PEA-eligible MSCI World ETFs (CW8, DCAM, WPEA…) all share nearly 100% overlap since they track the same index via a synthetic swap. Comparison comes down to TER, AUM and distribution policy. The ETF Overlap simulator helps verify two candidate ETFs do not duplicate unnecessarily.
CW8, DCAM, WPEA : what is the practical difference ?
All three are PEA-eligible synthetic ETFs tracking the MSCI World. They differ by issuer (Amundi for CW8 and DCAM, Invesco for WPEA), TER, AUM and launch date. Their mutual overlap exceeds 99% since the swap-delivered performance is by construction that of the target index.
Why does an MSCI World ETF cost more than an S&P 500 ETF ?
The MSCI World contains roughly 1,400 lines versus 500 for the S&P 500. Replication costs (administrative management, component arbitrage, MSCI licensing fees) are mechanically higher. MSCI World ETFs typically charge a TER between 0.12% and 0.38%, versus 0.03% to 0.20% for S&P 500 ETFs.
Should I prefer physical or synthetic replication for the MSCI World ?
In a standard brokerage account, physical replication is more transparent since the fund directly holds the securities. In a PEA, only synthetic ETFs are available since PEA eligibility requires this mechanism. Swap counterparty risk exists in theory but is limited by UCITS regulation (collateralization, quality counterparty, 10% limit).
Is a single MSCI World ETF enough to diversify a portfolio ?
The MSCI World covers 23 developed countries but excludes emerging markets (China, India, Brazil…) and small caps. It is heavily concentrated on the US (around 70%) and on mega-cap tech. Many investors complement it with an MSCI Emerging Markets ETF and possibly a small caps ETF to broaden geographic and size diversification.
How to compute the real cost of an MSCI World ETF over 10 years ?
TER is applied as a percentage of assets under management each year. For €10,000 invested at 0.38% TER, the annual cost is €38 the first year and grows with capital appreciation. Over 10 years, at 8% gross annual performance, the gap between 0.12% and 0.38% TER represents around €280 to €320 of cumulative additional fees.
