Cheapest all-world ETF 2026: VWCE vs WEBN vs FWRA vs the rest

By Kestutis Balciunas·Reviewed August 24, 2026

The hunt for the cheapest all-world ETF in 2026 comes down to a handful of UCITS funds: Vanguard’s VWCE, Amundi’s WEBN, Invesco’s FWRA, SPDR’s SPYI and a few others fighting over the same job. That job is simple — own the whole global stock market in one fund, for as little as possible. The fee war of the past three years has been wonderful for European investors, but it has also made the choice more confusing than it used to be.

I have held all-world trackers for most of my eleven years of investing, and this page is the roundup I wish had existed when the price war started. Below you will find one big comparison table, an honest look at why the headline TER misleads, the index question in plain language, and a fund-by-fund verdict. Furthermore, I tell you exactly what I would buy today, with my reasoning on show.

The cheapest all-world ETF contenders at a glance

Six funds cover the realistic field for a European investor in 2026. Every TER below is illustrative — providers reprice, so check the current figure on the issuer factsheet or justETF before you buy.

How we compare: fund picks here follow our published ETF comparison methodology — TER, tracking difference, liquidity and domicile, in that order.

All figures approximate at the time of writing. Check current TER, AUM and index details on each issuer’s factsheet — these numbers change, and this fee war is not over.

Rates referenced here follow our country-by-country ETF tax table, checked against official sources.

On price alone, WEBN wins and it is not close. However, price alone is a poor way to choose, and the next two sections explain why.

Why the TER alone misleads

The TER is the number in the marketing material. It is not the number that lands in your account. What actually matters is the tracking difference — the gap between the fund’s real return and its index over a given period. That gap bundles together the TER, internal trading costs, withholding-tax efficiency and any revenue the fund earns from securities lending. I explain the mechanics fully in my guide to ETF tracking difference, but the short version is this: some funds beat their headline fee, and some quietly trail it.

All six funds above are Irish-domiciled UCITS vehicles. Consequently, they all enjoy the 15% US dividend withholding rate under the Ireland–US treaty, which matters enormously for portfolios that are majority US equities. On that front the playing field is level. Where they differ is in replication style, lending policy and sheer experience:

• Securities lending. WEBN, FWRA and VWCE all lend a portion of their holdings. The revenue offsets costs and can pull tracking difference below the TER. It also adds a small, collateralised counterparty exposure — a fair trade, in my view, but one you should know you own.
• Replication. FWRA samples roughly 2,300–2,400 of the FTSE All-World’s ~4,000 stocks; VWCE holds nearly everything; SPYI samples a vast 9,000-stock index. Sampling is normal and usually harmless, yet it adds a little room for the fund to drift from its benchmark.
• Track record. VWCE, SPYI and ISAC have a decade or more of published tracking history across bull and bear markets. WEBN has roughly two years; FWRA roughly three. Early numbers for both are genuinely encouraging — but early data is early data.

The practical consequence: a 0.07% fund tracking at 0.10% costs you more than a 0.15% fund tracking at 0.08%. The gaps here are small enough that realised tracking, not the sticker price, decides the true winner — and realised tracking is only knowable in arrears. That is the honest reason this article cannot simply crown one fund and go home.

The index question: FTSE vs Solactive vs MSCI

The second complication is that these funds do not all track the same index, so this is not a pure price comparison.

FTSE All-World (VWCE, FWRA) covers around 4,000 large and mid-cap stocks across developed and emerging markets. It is the benchmark most European investors know by heart. Notably, FTSE classifies South Korea as a developed market.

MSCI ACWI (ISAC) covers similar ground with slightly fewer stocks, and classifies South Korea as emerging. MSCI ACWI IMI (SPYI) extends the same universe down into small caps — roughly 9,000 stocks in total, making it the broadest one-fund portfolio on this list.

Solactive GBS Global Markets Large & Mid Cap (WEBN) is the newcomer’s choice. Solactive licenses its benchmarks far more cheaply than FTSE or MSCI, and Amundi passes that saving on through the ultra-low TER. The exposure is an all-country, cap-weighted world portfolio that behaves almost identically to the FTSE All-World — but the inclusion rules, rebalancing schedule and country classifications differ in small ways, so returns will drift apart by a few basis points either way over time.

Does the index choice matter? Less than most investors fear, more than zero. All four benchmarks deliver the same core outcome: the United States at well over half the portfolio, the usual mega-cap names on top, emerging markets around a tenth. Over decades, I expect the differences to wash out to rounding error. Nevertheless, if you specifically want the FTSE All-World, FWRA and VWCE are your only two candidates — which narrows the decision usefully.

Fund-by-fund mini-verdicts

WEBN — the price-setter. At ~0.07%, the Amundi Prime All Country World fund redefined what “cheap” means in Europe. Physical, Irish-domiciled, ~3,400 stocks, and early tracking that has stayed close to the fee. The caveats are youth and the less familiar Solactive index. Full details in my WEBN factsheet. Verdict: the default for cost-focused new money.

FWRA — the same index for less. Invesco’s fund tracks exactly the index VWCE tracks, at roughly a third off the fee. It trades as FWRA, FWIA or FWRG depending on the exchange — one fund, three tickers. Sampling and a 2023 launch date are the honest asterisks. My FWRA factsheet covers the share-class maze. Verdict: the pick if the FTSE index matters to you and the price matters too.

SPYI — the completeness play. SPDR’s ACWI IMI fund is the only one here that includes small caps, at ~0.17% with a history stretching back to 2011. You pay a little more than WEBN and get several thousand more companies plus a long record. Verdict: for investors who want truly everything in one line and value maturity.

ISAC — the established MSCI option. iShares’ ACWI fund offers the MSCI flavour of the world at ~0.20% with big assets and a long history. It is a fine fund; the difficulty is that it is neither the cheapest, the broadest, nor the biggest. Verdict: sensible if your broker or plan favours iShares, rarely the outright winner otherwise.

VWCE — the incumbent. Vanguard’s flagship remains the reference point: massive, liquid, near-fully replicated, with the longest FTSE All-World record in the accumulating format. At ~0.14% after its 2025–26 fee cuts it has rejoined the price fight — only WEBN still undercuts it meaningfully. My VWCE factsheet has the full picture. Verdict: still an excellent hold; harder to justify for brand-new money on price alone.

V3AA — the ESG variant. Vanguard’s ESG Global All Cap applies exclusion screens to a global all-cap universe at ~0.24%. Be clear-eyed: the screens mean it is not the market — sector and country weights shift, and returns will deviate from the plain trackers in both directions. Verdict: only for investors whose priority is the ESG screen itself, not the lowest cost.

Cheapest all-world ETF: who should pick which

If the big table answers “what exists”, this one answers “which is for me”.

Two practical notes cut across every row. First, broker availability decides more of this than any spreadsheet: WEBN’s listings centre on Xetra, gettex and Borsa Italiana, while VWCE trades essentially everywhere — and a fund you cannot buy cheaply in a monthly savings plan is not cheap for you. Secondly, switching an existing holding with large unrealised gains can trigger a tax bill that decades of fee savings never recoup. New money is where the fee war pays off.

My take: the cheapest all-world ETF I would buy today

Here is my honest position, and I will show my reasoning rather than hedge. If I were starting a portfolio from zero this morning, I would buy WEBN. The structure is conventional — physical replication, Irish domicile, a mainstream all-country universe — and the ~0.07% fee is a durable advantage, not a teaser. Two years of tight tracking do not prove the next twenty, but every structural ingredient points the right way, and I weigh the head-to-head in VWCE vs WEBN.

If the Solactive index bothered me — and for some investors the comfort of the FTSE name has genuine value — I would buy FWRA and consider it a rounding error away. The decision between those two is closer than the fee gap suggests, which is why I wrote up WEBN vs FWRA separately.

And what about my own money? I hold established positions with embedded gains, so I do the boring, tax-aware thing: I keep what I own and direct new contributions to the cheaper funds. Selling a decade of VWCE gains to save 0.15 percentage points would hand my tax office a cheque that no fee saving repays in my lifetime. Boring is usually right in investing, and I would rather tell you that than pretend I churned my whole portfolio the day a cheaper ticker listed.

Common mistakes

• Choosing on TER alone. Tracking difference is the real cost. A cheap fund that tracks loosely can lose to a dearer fund that tracks tightly — check realised numbers, not just the sticker.
• Selling a winner to switch. Realising large gains to save a few basis points is usually a net loss after tax. Direct new money to the cheaper fund instead.
• Confusing share classes. WEBN vs WEBG, FWRA vs FTWD, VWCE vs VWRL — one letter separates accumulating from distributing, and the tax outcome differs meaningfully. Verify the ISIN.
• Ignoring broker costs. A 0.07% TER means little if your broker charges high dealing fees on that exchange line. Total cost includes the buying.
• Assuming all “world” indices are identical. FTSE, MSCI and Solactive make different country and size cut-offs; small caps are only in SPYI and V3AA’s universes. Similar is not the same.
• Treating today’s fee table as permanent. The price war is live and providers reprice — check before every purchase, and do not churn on every headline.

Key takeaways

• WEBN (~0.07%) is the cheapest all-world ETF for European investors in 2026 on headline fee; VWCE (~0.14%), FWRA (~0.15%), SPYI (~0.17%) and ISAC (~0.20%) complete the realistic field — always confirm live figures on the issuer factsheet.
• TER is not total cost: tracking difference, which folds in trading costs, withholding tax and lending revenue, decides the real winner — and only shows up in arrears.
• The index matters: VWCE and FWRA share the FTSE All-World; ISAC and SPYI use MSCI benchmarks (SPYI adds small caps); WEBN uses a cheaper-to-license Solactive index that behaves almost identically.
• Fund age is the honest trade-off — WEBN and FWRA are young with short records; VWCE, SPYI and ISAC bring a decade or more of published tracking history.
• New money favours the cheap challengers; switching an existing position with large gains rarely survives the tax maths. My full head-to-head grid lives in the all-world comparison hub.

FAQ

Q: What is the cheapest all-world ETF in 2026?
A: By headline TER, Amundi’s WEBN at roughly 0.07%. VWCE (~0.14%), FWRA (~0.15%), SPYI (~0.17%) and ISAC (~0.20%) follow. Fees change, so verify current figures on the issuer factsheet before buying.

Q: Is WEBN better than VWCE?
A: WEBN is roughly half of VWCE’s fee for near-identical exposure, but it is far younger and tracks a Solactive rather than FTSE index. For new money the cost case is strong; for existing VWCE holders with gains, switching often fails the tax maths.

Q: Why is the TER not the whole story?
A: Because the real cost is the tracking difference — the gap between fund and index returns after trading costs, withholding tax and securities-lending income. Some funds run tighter than their TER, others looser.

Q: Does the index — FTSE, MSCI or Solactive — really matter?
A: Less than the marketing suggests. All are cap-weighted, all-country benchmarks with the US dominant. Differences in country classification and inclusion rules produce small return gaps in either direction, not a systematic winner.

Q: Which cheap all-world ETF includes small caps?
A: SPDR’s SPYI (MSCI ACWI IMI) is the only mainstream low-cost option covering small caps, with roughly 9,000 stocks in its universe. The others hold large and mid caps only.

Q: Are the new cheap funds like WEBN and FWRA safe?
A: They are conventional Irish UCITS funds with segregated assets, so the regulatory protection matches any established ETF. The genuine “youth” risks are shorter tracking records and thinner liquidity on some lines — not the safety of your capital.

Q: Should I sell VWCE and buy WEBN or FWRA?
A: Usually not if you hold meaningful unrealised gains in a taxable account — the tax bill typically outweighs decades of fee savings. Directing new contributions to the cheaper fund is the cleaner move.

Q: What is the difference between WEBN and WEBG?
A: Same Amundi fund, different share classes: WEBN accumulates dividends internally, WEBG pays them out. Most accumulation-phase investors prefer WEBN for compounding and tax deferral.

Q: Why does FWRA have three tickers?
A: FWRA, FWIA and FWRG are one accumulating fund listed on different exchanges — Borsa Italiana and the LSE, Xetra and gettex, and the LSE in pence respectively. Check the ISIN (IE000716YHJ7), not just the ticker.

Q: Is V3AA a fair comparison to the others?
A: Only partly. Its ESG screens exclude whole categories of companies, so it is not a neutral market tracker and its returns will deviate from the plain funds. Choose it for the screening, not the price.

Q: Could an even cheaper all-world ETF appear?
A: Quite possibly — 0.07% may not be the floor. All the more reason to avoid tax-costly switching on every launch; new contributions can simply go to the current leader.
