A prominent French finance YouTuber recently announced a radical portfolio shift: abandoning synthetic ETFs for physical replication, citing fears of permanent liquidation if geopolitical tensions escalate. The trigger? Russian ETFs frozen in 2022. The concern? That European regulators might block synthetic ETF assets during a crisis, leaving investors with nothing.
This move sparked heated debate across French investment communities. Many called it prudent risk management. Others dismissed it as fear-mongering that confuses Russian financial isolation with European regulatory reality. The discussion reveals a critical blind spot in how French investors understand their ETF structures, especially those held in PEA (Plan d’Épargne en Actions) accounts.
The Russia Precedent: What Actually Happened
When Western sanctions hit Russia in 2022, ETFs exposed to Russian assets faced immediate consequences. Funds couldn’t trade frozen securities. Some suspended redemptions. Others wrote down holdings to zero. The mechanics were brutal but straightforward: sanctions made the underlying assets untouchable.
But here’s where the comparison gets problematic. Russian ETFs represented a tiny, isolated market with negligible cross-border financial integration. European regulators had no incentive to protect Russian asset holders. The political calculus was simple: punish Moscow, protect Western financial systems.
European synthetic ETFs operate under entirely different constraints. These funds use swaps, derivative contracts with major banks, to replicate index performance while holding a separate basket of European securities. The swap counterparty (typically a systemic bank like BNP Paribas or Société Générale) promises to deliver the index return in exchange for the performance of the European stock basket.
Why French Investors Shouldn’t Panic, Yet
The argument that “if Russia happened, Europe could too” ignores several realities of the French investment landscape.

First, PEA eligibility rules create a built-in protection mechanism. To qualify for the tax-advantaged PEA, an ETF must hold at least 75% European assets. This means synthetic ETFs in French portfolios already contain substantial directly-owned securities. Even if a swap failed, investors would retain this underlying basket.
Second, European regulators have demonstrated no appetite for confiscating individual investor assets during crises. The 2008 financial collapse, the Greek debt crisis, and the COVID-19 market panic all tested European financial stability. In each case, regulators protected retail investors, often at taxpayer expense. The political cost of seizing ETF assets would be catastrophic.
Third, the scale difference matters. Russian ETFs represented a rounding error in global finance. European ETFs hold trillions in assets across millions of European households. Liquidating them would trigger a financial crisis far worse than the underlying geopolitical conflict.
The Counterparty Risk That Actually Matters
This doesn’t mean synthetic ETFs are risk-free. The real danger isn’t geopolitical liquidation, it’s counterparty failure during market stress.
If a swap provider (the bank guaranteeing the index return) collapses, the synthetic ETF loses its performance engine. The European stock basket remains, but its value may diverge sharply from the intended index. During the 2008 crisis, several synthetic ETFs faced exactly this scenario when Lehman Brothers failed as a swap counterparty.
French investors should examine their ETF documentation for:
– Swap enhancement terms (some issuers negotiate favorable conditions that improve performance)
– Collateral requirements (quality banks post collateral against swap exposure)
– Counterparty diversification (some ETFs use multiple banks)
The UCITS (Undertakings for Collective Investment in Transferable Securities) framework governing European ETFs mandates strict collateral rules. Swap providers must post high-quality collateral, typically government bonds, marked to market daily. If a counterparty defaults, the ETF can seize this collateral to offset losses.
Physical vs. Synthetic: The Performance Trade-Off
Physical ETFs seem safer, they own the actual stocks. But they carry their own risks, especially for French investors using PEA accounts.
To access non-European indices like the S&P 500 in a PEA, you must use synthetic ETFs. The 75% European asset rule makes physical replication impossible for global indices. If you want true international diversification within France’s flagship tax wrapper, synthetic is your only option.
Physical ETFs also face custody risk. The fund’s assets sit with a custodian bank. If that bank fails (think Lehman), recovery can take years. During the MF Global collapse in 2011, clients waited months to access supposedly “safe” segregated accounts.
Synthetic ETFs, conversely, often hold their European stock basket at multiple custodians, reducing single-point-of-failure risk.
The “We’ll Have Bigger Problems” Fallacy
Many French investors argue that if European synthetic ETFs face liquidation, society itself has collapsed, making financial concerns irrelevant. This reasoning appears frequently in online discussions, but it’s flawed.
Financial crises don’t require societal collapse. The 2008 crisis froze credit markets but grocery stores still functioned. The Greek crisis imposed capital controls but daily life continued. Investors who prepared for financial system stress, by diversifying custodians, asset classes, and jurisdictions, preserved capital while others panicked.
The question isn’t whether you’ll need your ETF money to buy bread during nuclear winter. It’s whether you can maintain portfolio value during a localized financial shock that leaves broader society intact.
Practical Steps for French ETF Investors
Rather than abandoning synthetic ETFs entirely, consider these targeted risk controls:
-
Split between synthetic and physical: Use synthetic for PEA-eligible global exposure, physical for European indices where both options exist. This diversifies your structural risk.
-
Check issuer strength: Amundi, BNP Paribas, and iShares (BlackRock) dominate French ETF markets. Their systemic importance makes government support likely during a crisis. Smaller issuers lack this implicit guarantee.
-
Read the KIID (Key Investor Information Document): French regulations require this document to clearly state counterparty risk. Look for collateral levels and swap provider identity.
-
Consider your wrapper: ETFs held in assurance-vie (life insurance) contracts benefit from additional French regulatory protections. PEA accounts offer tax advantages but fewer institutional safeguards.
-
Monitor swap spreads: If a synthetic ETF suddenly underperforms its index significantly, the swap may be stressed. This rarely happens but warrants attention when it does.
The Real Geopolitical Risk Hiding in Your Portfolio
The YouTuber’s fear wasn’t entirely misplaced, just misdirected. The bigger geopolitical risk for French ETF investors isn’t asset seizure, it’s tax rule changes.
France has already demonstrated willingness to alter investment tax treatment. The 2017 reform of wealth tax (ISF to IFI) shifted incentives dramatically. A future government could modify PEA rules, change dividend taxation, or restrict foreign asset holdings.
These policy shifts pose greater threat to long-term returns than hypothetical asset freezes. Unlike counterparty risk, you can’t hedge against legislative risk with collateral or diversification.
Bottom Line: Context Over Fear
Comparing Russian ETFs to European synthetic structures makes for dramatic YouTube content but poor financial planning. The legal, regulatory, and political contexts differ so profoundly that the parallel breaks down under scrutiny.
That said, the discussion highlights a valuable truth: most investors don’t understand their ETF mechanics. Whether synthetic or physical, you should know:
– What your fund actually owns
– Who guarantees its performance
– Where your assets are custodied
– What happens if key counterparties fail
For French investors navigating PEA constraints, synthetic ETFs remain essential tools. Rather than eliminating them based on geopolitical fears, use them strategically while monitoring the real risks: counterparty strength, collateral quality, and regulatory changes.
The market punishes ignorance more than it rewards excessive caution. Understanding your synthetic ETF’s structure beats abandoning it for a false sense of safety.
