The global investment landscape is undergoing a rapid and disorderly reset as the ongoing Iran conflict disrupts one of the most crowded market narratives of the past year. What began as a geopolitical escalation has now evolved into a full-blown macro shock, forcing investors to unwind positions built around falling interest rates, artificial intelligence-led equity expansion, and diversification away from US assets.

According to a Bloomberg report, global equity markets have shed nearly $14 trillion in value since the conflict intensified, marking one of the sharpest drawdowns in recent years. The correction comes after a sustained rally driven by optimism around monetary easing and technology-led earnings growth, particularly in developed markets.

At the heart of the disruption lies the oil market. The near-closure of the Strait of Hormuz a critical chokepoint that carries roughly 20% of global oil supply has triggered a sharp spike in crude prices. Energy consultancy estimates suggest oil could surge to $150–$200 per barrel if disruptions persist for several weeks. This has fundamentally altered inflation expectations and forced bond markets to reprice the interest rate trajectory.

The shift marks a stark contrast to market behavior following US President Donald Trump’s tariff measures last year, which had weakened the US dollar and encouraged capital flows into emerging markets and non-US equities. That “Sell America” trade is now reversing. The dollar has strengthened significantly, rising 2.4% in March alone, supported by its safe-haven appeal and the United States’ position as a net energy exporter.

US equities have also shown relative resilience. While the S&P 500 declined over 5% in March, the fall has been less severe compared to broader global indices, particularly in Europe and Asia, where economies remain more sensitive to energy imports and interest rate volatility. Energy-linked stocks in the US have provided a partial buffer against broader market declines.

Emerging markets, however, have borne the brunt of the adjustment. Equity indices tracking developing economies have dropped sharply, registering their worst monthly performance in six years. Currency markets have also weakened, reflecting capital outflows and vulnerability to rising import bills. The combination of higher oil prices and a stronger dollar has tightened financial conditions across these economies, undermining growth expectations.

Investor sentiment is now highly contingent on the trajectory of the conflict. Signals from Washington and Tehran suggesting a possible de-escalation have offered some near-term relief. However, even if a resolution materializes within weeks, market participants expect supply chains and energy flows to take time to normalize, prolonging volatility.
