If you’re a European investor holding international ETFs unhedged, a rising euro in 2026 could quietly erase a chunk of your hard-earned returns. This isn’t hypothetical. We’ve seen this movie before—investors who ignore currency impact on ETF returns in Europe often get blindsided. Let’s get real: if you’re still treating FX risk as some background noise, prepare for a nasty wake-up call.
Here’s my thesis: Unless you’ve actively positioned your portfolio, a strengthening EUR will sap performance from your global ETFs, especially the beloved IWDA and VWCE. I’ll show you exactly how, with numbers, examples, and a clear call to action—because 2026 isn’t the year to be complacent about currency risk.
How Currency Impact Eats Your Global ETF Returns
Unhedged international ETFs are a double-edged sword. You get global diversification, but you’re also making a hidden FX bet. Let’s break this down:
From 2017 to 2020, the USD/EUR exchange rate fell from 0.95 to 0.82—a 13% swing. Over that period, European investors in US equity ETFs saw their returns slashed by the stronger euro, regardless of how the S&P 500 performed in USD terms.
With the euro poised to rebound as the ECB hints at fewer rate cuts than the Fed (see Bloomberg May 2024), this scenario is back on the table. Here’s a concrete example:
- You hold €100,000 in VWCE (Vanguard FTSE All-World UCITS ETF), which is 60% exposed to USD assets.
- VWCE posts a 7% USD return in 2026, but the EUR/USD jumps from 1.07 to 1.15 (+7.5%).
- Your ETF’s EUR return? Near zero. The FX impact wipes out your dollar gains.
Let’s not pretend this is rare. In 2017, the MSCI World Index returned 22% in USD—but for EUR investors, the return was just 7% after a 14% currency drag (MSCI 2017 Factsheet).
VWCE, IWDA, and the Hidden Cost of a Stronger Euro
Let’s get specific—because if you’re still buying into “international diversification always works,” you’re not paying attention. Two of Europe’s most popular UCITS ETFs—VWCE and IWDA—are both unhedged and heavily exposed to USD:
- VWCE: ~60% US equities
- IWDA: ~67% US equities (see our detailed comparison)
Last time the euro surged (2017), IWDA returned just 7% in EUR, lagging its 23% USD return. In 2022, the shoe was on the other foot: the euro dropped from 1.14 to 1.06 versus the dollar (-7%), and IWDA’s EUR returns outpaced USD, juiced by the weaker euro.
So if market consensus is right and the euro strengthens to 1.15 or higher in 2026, expect your US-heavy global ETFs to underwhelm. As for emerging market allocations in VWCE, a strong euro will eat into those returns too—currencies like CNY and BRL tend to weaken versus EUR when Europe outperforms.
The Bottom Line
If you’re betting on global growth with VWCE or IWDA and ignoring currency impact, you’re not diversified—you’re just gambling on a weak euro.
To Hedge or Not to Hedge: When Does EUR Hedging Make Sense?
Hedging isn’t just for institutional quants. Any European investor with a sizable global allocation should be thinking about it. Here’s when EUR-hedged ETFs make sense:
- You need predictability. Planning a large EUR-denominated purchase—house, tuition, retirement? Why risk a 10% swing based on FX?
- The euro is undervalued. If you believe the euro will bounce back (as many do in 2026), hedging cushions those gains.
- Your time horizon is short. In 1–3 years, currency moves can swamp stock returns. Hedging protects short-term goals.
But let’s not sugar-coat the costs: EUR-hedged ETFs typically carry higher TERs (by 0.10–0.20%) and may lag in yield if the euro weakens.

The Case Against Hedging: Why Some Investors Still Roll the Dice
Let’s steelman the purists. There are times when currency risk is a feature, not a bug:
- Long-term investors (10+ years) can afford to ride out FX volatility. Over decades, major currencies often mean-revert, and the cost of hedging compounds.
- Hedging isn’t perfect. Tracking errors, extra fees, and imperfectly matched hedges all nibble at returns.
- If the euro weakens, unhedged wins. From 2021–2022, EUR fell 7%—unhedged ETF holders got a higher return than their USD-based counterparts.
If your goal is maximum diversification, or you want FX tailwinds when the euro underperforms, unhedged ETFs can (sometimes) deliver. But let’s not pretend you have no currency view. You’re still making a bet—just passively.
How to Limit Currency Risk in Your 2026 ETF Portfolio
If you want to avoid being a casualty of currency impact on ETF returns in Europe, you need a plan. Here’s how to future-proof your returns:
- Mix hedged and unhedged ETFs strategically. Use VWCE/IWDA for long-term global exposure, but add a ~30% hedged allocation if you see euro strength ahead.
- Stress test your portfolio regularly. Model a 10% EUR/USD move and see how much it hits your returns. Use tools like ETF Portfolio Stress Testing: How to Prepare for Market Volatility in 2026 for realistic scenarios.
- Keep large near-term EUR spending in cash or short-term EUR bonds. Don’t gamble with tuition or house down payments on FX swings.
Bottom line: don’t sleepwalk into FX risk. If your portfolio is 70%+ in unhedged global equities, you’re exposed—and if the euro jumps in 2026, your net returns could be flat even if global stocks soar.
Conclusion: Ignore Currency Impact at Your Own Peril
Most European ETF investors are one currency swing away from disappointment. The data is clear: a rising euro can wipe out years of index gains overnight.
My prediction? In 2026, the ECB–Fed rate gap and a rebound in European exports will push EUR/USD to at least 1.15. If you’re all-in on unhedged VWCE and IWDA, expect your “world beating” ETF returns to fizzle when translated into euros.
Don’t just diversify across stocks—diversify your currency risk. Add hedged positions, model scenarios, and act like your money’s on the line. Because it is. If you do nothing, you’re not diversified—you’re just hoping the euro stays weak. Hope is not a strategy.
