BlackRock's Global ETF Defies Headwinds with Strong Investor Support

Despite new tariffs, a fierce fee war, and an upcoming index overhaul, the iShares MSCI World ETF (URTH) attracted nearly $0.5B in 5 days, showing resilience.

The iShares MSCI World ETF (URTH) continues to attract significant capital, pulling in nearly half a billion US dollars over just five trading days. This steady inflow has pushed its assets under management to approximately $7.5 billion, a notable show of resilience given the array of challenges currently facing the fund. From new trade tariffs to a fierce fee war and an impending index overhaul, the environment is far from calm.

A major source of pressure stems from recent US trade policy. On April 2, President Trump signed an executive order imposing a 100% tariff on imported patented pharmaceuticals, with a reduced 15% rate for products from the EU, Japan, South Korea, Switzerland, and Liechtenstein. Leveraging Section 232 of the Trade Expansion Act of 1962, these measures are considered more legally robust than previous tariffs largely overturned by the Supreme Court in February 2026. Analysts estimate the pharmaceutical tariffs could dampen global growth and add roughly 0.5 percentage points to inflation, directly squeezing profit margins for major index constituents.

This trade friction hits the fund's largest allocations hard. The technology sector, representing 26.5% of the portfolio, is particularly exposed. Nvidia, Apple, and Microsoft—which together account for about 13.6% of the fund—rely heavily on Asian supply chains now under increasing strain. Nvidia has been the fund's single largest holding since mid-January 2026. The heightened uncertainty was reflected in trading activity, with volume spiking to 654,315 shares on April 1, a 26% increase from the previous day.

Simultaneously, competitive pressure on costs is intensifying. On April 1, Invesco slashed the annual management fee for its $6.6 billion MSCI World UCITS ETF from 0.19% to 0.05%. This move creates a 19-basis-point gap compared to URTH's total expense ratio of 0.24%. Invesco is not alone; UBS cut its fee to 0.06% in May 2025, and BNP Paribas followed in September 2025 with its own MSCI World ETF priced at 0.05%. In its March 31, 2026 assessment, Morningstar awarded URTH a Bronze medal but noted the fund could be more competitively priced.

Despite the growing fee disadvantage, major institutional investors have shown steadfastness. The Royal Bank of Canada increased its position by 17.5% in the fourth quarter of 2025, acquiring roughly two million shares. This suggests the fund's deep liquidity and strong brand recognition continue to hold value for some allocators.

Looking ahead, a significant structural change is on the horizon for May 2026. MSCI will implement a fundamental revision to its free-float calculation methodology, introducing a new framework that categorizes a company's freely tradable share portion into three tiers. Because the March rebalancing was intentionally minimal, market observers anticipate a substantially higher portfolio turnover than usual in May. Early signs of realignment were visible in Q1, with US equities being reduced on a net basis for the first time in years and new positions like AST SpaceMobile and FTAI Aviation being added.

One potential source of selling pressure has been averted, however. MSCI has withdrawn its proposal to exclude companies with high crypto exposure from its major indices. The current treatment of firms where crypto assets represent 50% or more of total assets remains unchanged for now.

Income-focused investors have another date to watch: June 15, 2026, is the next ex-dividend date. This follows a period where the fund's dividend growth year-over-year surpassed the 20% mark. Whether institutional loyalty persists in the face of cheaper alternatives and the coming index reshuffle will be revealed in the capital flows of the coming weeks.
