Why invest through a PEA?

The PEA (Plan d'Épargne en Actions) is France's most advantageous tax wrapper for equity ETF investing. After 5 years, capital gains are exempt from income tax and only subject to social contributions (17.2%) instead of the 30% flat tax.

On €30,000 invested for 20 years at 7% annually, the tax saving exceeds €8,000. The PEA is capped at €150,000 in contributions (€225,000 with the PEA-PME).

Which ETFs are PEA-eligible?

PEA regulations require that at least 75% of the fund's assets be in EU/EEA-based companies. This naturally excludes major global indices like the MSCI World (70% US-dominated) or the S&P 500.

The solution for accessing the MSCI World or S&P 500 through a PEA: synthetic replication ETFs.

How can an MSCI World ETF be PEA-eligible?

The technique is the performance swap (synthetic replication). The fund holds EU-eligible equities in its portfolio (giving it regulatory eligibility), while simultaneously entering into a swap agreement with a bank counterparty that commits to delivering the MSCI World's performance.

The three main issuers offering this: Amundi (CW8), Invesco (WPEA), and BNP Paribas Easy (EWLD). Counterparty risk is capped at 10% of net assets by UCITS regulation.

CW8 vs WPEA: which to choose?

CW8 — Amundi MSCI World UCITS ETF

The oldest and most well-known PEA MSCI World ETF in France. Over €4 billion in AUM, available on virtually all French brokers. TER: 0.38% — the highest of the three main options.

WPEA — Invesco MSCI World UCITS ETF (Acc)

With a TER of 0.19% (cut in 2026), WPEA is now the cheapest PEA-eligible MSCI World ETF. Its Tracking Difference has historically been negative (the ETF outperforms its benchmark thanks to securities lending income), making it the most cost-efficient choice.

EWLD — BNP Paribas Easy MSCI World SRI

The ESG-screened version. Excludes lowest-rated companies on ESG criteria. TER: 0.25%. Suitable for ESG-conscious investors.

Should you combine multiple PEA ETFs?

For a simple, efficient portfolio, a single MSCI World ETF is sufficient. It covers 1,400 companies across 23 developed countries.

The CW8 + S&P 500 PEA combination is a common trap: the overlap between these two ETFs exceeds 65%. You pay fees on two products for near-identical diversification.

In summary

For a French investor wanting MSCI World exposure through a PEA, WPEA is today the best choice thanks to its 0.19% TER and historically negative Tracking Difference. CW8 remains an excellent, more widely available alternative. Avoid combining a MSCI World PEA ETF with an S&P 500 PEA ETF — the 65%+ overlap dramatically reduces your actual diversification.
