A significant portfolio adjustment is taking effect for the Vanguard FTSE All-World UCITS ETF (USD Accumulation). As of the market close on March 20, 2026, the fund will implement all changes stemming from the latest FTSE Russell quarterly index review. This particular review carries added importance, as it coincides with the semiannual reassessment, which involves a comprehensive recalibration of all index constituents based on their current market capitalizations.
Spotlight on Non-US Equities
The rebalancing occurs during a period where international stock markets are notably outperforming their US counterparts. In 2025, the Morningstar US Market Index posted a 17% gain. In stark contrast, the global ex-US index surged by 32% in US dollar terms, marking the largest performance gap since 2005. Vanguard’s own 2026 outlook projects annualized returns of 4.9% to 6.9% for non-US stocks over the next decade, compared to a 4% to 5% range for US equities.
In its March 2026 assessment, Morningstar awarded the fund a Silver rating, indicating it possesses above-average potential relative to its category. With total assets under management of approximately $56.8 billion and an ongoing charge of 0.19%, this ETF remains one of the largest and most cost-efficient vehicles of its kind.
Vietnam’s Promotional Path
A structurally pivotal element of this review concerns Vietnam’s market classification. FTSE Russell has previously announced its intention to promote the country from “Frontier” to “Secondary Emerging Market” status, with a planned effective date of September 21, 2026. The current review includes an interim assessment to determine whether Vietnamese markets offer sufficient accessibility to international brokers.
Should Vietnam ultimately be included in the FTSE Emerging Index, its constituents would subsequently be phased into the broader FTSE All-World Index, thereby entering the ETF’s portfolio.
Shifts in the UK Blue-Chip Index
Changes within the UK’s flagship FTSE 100 index will also ripple through to the global benchmark. IG Group Holdings and Lion Finance Group are set for promotion to the FTSE 100. Conversely, EasyJet and Hikma Pharmaceuticals will be relegated to the FTSE 250 index. These moves will directly influence their respective weightings within the global index tracked by the Vanguard ETF.
Investors in the fund will see these updated weightings reflected when markets reopen following the implementation date.
