Oil above $85 as markets confront energy shock

Global markets retreated on Tuesday as the expanding Middle East conflict unsettled investors and revived concerns over energy supply. The S&P 500 fell 1.4% and the Nasdaq 1.5% percent, while Europe experienced sharper declines. The Stoxx 600 dropped 3.1% and Germany’s Dax 3.4%, reflecting a shift from viewing the conflict as a contained episode to pricing in the risk of a more sustained disruption.

Brent crude rose as much as 9% to above $85 a barrel before moderating, while European natural gas prices surged amid mounting strain on Gulf infrastructure and shipping routes. The Strait of Hormuz, a critical artery for global energy flows, has again become central to market calculations. When such corridors face uncertainty, ripple effects extend well beyond commodity markets, influencing inflation expectations, corporate margins and consumer sentiment.

Government bond yields climbed as traders reduced expectations of further rate cuts. Germany’s two year yield rose to 2.19%, with similar moves in the UK and the US. Markets that had grown comfortable with a steady disinflation narrative are reassessing the possibility that elevated energy prices could complicate monetary policy.

Beyond the immediate volatility, the episode highlights how deeply integrated the global economy remains. Energy shocks in one region rapidly transmit through financial markets, trade networks and supply chains. Economies with flexible capital markets, diversified energy strategies and strong institutional frameworks tend to adjust more smoothly to such shocks.

Investors now face a period defined less by abundant liquidity and more by geopolitical risk management. The path forward will depend on the duration of the conflict, the resilience of energy infrastructure and the capacity of markets to reprice risk without undermining longer term growth prospects.
