A Global Anchor: How a Major ETF Withstood Market Turbulence

The first quarter of 2026 presented global equity markets with mounting geopolitical tensions and a significant shift in capital allocation. Amidst this volatility, the iShares Core MSCI World UCITS ETF USD (Acc) demonstrated notable resilience. This multi-billion dollar fund has increasingly been utilized by investors as a core holding to achieve broad market exposure in an uncertain climate.

Defensive Positioning Amid Uncertainty

Despite the challenging backdrop, the fund’s underlying benchmark, the MSCI World Index, posted a positive return of 2.51% through the end of March. The iShares ETF, which tracks this index with a total expense ratio of 0.20%, provides exposure to over 1,300 companies across 23 developed nations. Its performance was bolstered by both its extensive diversification and its continued heavy weighting in the technology and financial sectors.

However, the broader market environment remained demanding. An escalating conflict in the Middle East and concerns over potential supply disruptions in the Strait of Hormuz pushed crude oil prices above USD 100 per barrel in early April. In response to these inflationary pressures and related interest rate worries, many participants adopted a more defensive stance. This was evidenced by increased capital flows into short-term government bond ETFs during March.

The Rotation in Investor Preferences

A clear change in investor behavior became apparent during the quarter. The initial euphoria in global stock markets cooled considerably by March, primarily due to heightened risks from the ongoing Middle East conflict, which amplified volatility across asset classes. Consequently, inflows into worldwide equity ETFs slowed as the period drew to a close.

Simultaneously, a remarkable rotation was underway. For the first time since early 2023, investments into international equities surpassed the volume of flows into U.S. stocks at the start of the year. European markets, in particular, saw investors rebalancing portfolios. Exposure to U.S. holdings was reduced over concerns regarding AI funding and political changes. The capital freed up by this shift was deliberately redirected into global strategies, emerging markets, and dividend-focused titles.

With approximately USD 124 billion in assets under management, the iShares Core MSCI World ETF maintains its position as a fundamental component for diversified portfolios. In the face of persistent geopolitical strains and a pronounced rotation away from U.S.-centric strategies, this vehicle continues to offer investors sought-after access to developed markets worldwide.
