$100 Oil? How Middle East Conflict Impacts Global Economy

Recent tensions in the Middle East have once again put global energy markets—and the broader economy—on edge. As the chart shows, geopolitical shocks continue to trigger sharp, immediate spikes in oil and gas prices, even if those surges don’t always last. The latest escalation involving US and Israeli strikes on Iran in early 2026 is no exception, with oil prices jumping quickly amid fears of supply disruption.

The Strait of Hormuz: The Market’s Critical Chokepoint

At the center of the concern is the Strait of Hormuz, a critical chokepoint for global oil flows. Any disruption here could send prices significantly higher and keep them elevated. That said, the base case among economists remains relatively contained: the conflict is expected to be short-lived, lasting weeks rather than months, with energy prices gradually settling back near pre-crisis levels, albeit with a lingering risk premium.

A Delicate Balancing Act and Inflation Risks

Still, the uncertainty is real. Iran faces a delicate balancing act between retaliating strongly enough to deter future attacks and preserving its vital oil revenues. This makes the situation difficult to predict and raises the risk of unintended escalation. If disruptions to shipping or production persist, higher energy prices could stick around longer, feeding into global inflation and slowing economic growth.

Why the Global Economy is More Resilient Today

Even in a downside scenario, however, the global economy appears more resilient than in past crises. Oil markets are better cushioned today, with OPEC holding enough spare capacity to offset potential supply losses. Meanwhile, the US and its allies are expected to act quickly to keep key shipping routes open, limiting prolonged damage.

The Macroeconomic Impact and the Bottom Line

The macroeconomic impact, while negative, is likely to be moderate. Sustained oil prices around US$100 per barrel could shave about 0.5 percentage points off global growth and push inflation up by roughly one point. That’s meaningful, yes, but not enough, on its own, to trigger a global recession.

In short, while geopolitical tensions continue to test the system, the global economy is proving more adaptable. The real risk lies not in the initial shock, but in how long it lasts.
