Geopolitical escalation in the Middle East is triggering immediate waves of risk-off trading across global financial markets. As passive funds now constitute the majority of US fund assets, capital flows have become a primary driver of market volatility during crises. Diversified index-tracking portfolios face direct exposure to sensitive sectors including energy, defense contractors, and airlines. The structural shift toward passive investing means that geopolitical shocks now trigger broad market movements regardless of individual stock fundamentals. While energy and defense sectors often see gains during such conflicts, airlines and broader equities typically face significant bearish pressure. Investors are increasingly challenged by the speed of market reactions, which often occur before traditional portfolio adjustments can be implemented.
