Brent Crude Hit $126 at Its Peak — Here Is the Full Economic Damage Map

Brent crude peaked at $126 per barrel during the Iran war — the largest energy supply disruption since the 1970s. Here is the complete map of economic damage by sector and country.

The 2026 Strait of Hormuz crisis Wikipedia article confirms that Brent crude surpassed $100 per barrel on March 8, 2026 for the first time in four years, rising to $126 per barrel at its peak — described as 'the largest disruption to the energy supply since the 1970s energy crisis, as well as the largest in the history of the global oil market.' Understanding the specific economic geography of this disruption requires mapping its particular effects by commodity, sector, and geography.

For the oil price trajectory: from approximately $75 pre-war to $126 at peak represents a 68 percent increase — the specific magnitude that translates to approximately $0.80 additional cost per gallon of gasoline in the US retail market, elevated airline ticket prices, increased heating costs, and the particular industrial energy cost increases that manufacturing-intensive economies absorb most severely.

For the fertiliser dimension: the Wikipedia crisis article confirms that 'up to 30% of internationally traded fertilizers normally transit the Strait of Hormuz' and that 'unlike oil, the fertilizer sector does not have internationally coordinated strategic reserves, making supply disruptions more difficult to manage.' Early March saw Middle East granular urea prices rise nearly 20% from late February levels.

For the aluminium dimension: aluminium was specifically listed as one of the commodity markets suffering price increases — the particular industrial metal whose specific energy intensity in production makes it acutely sensitive to energy price increases, and whose specific Gulf state production (Bahrain and UAE's Aluminium operations were specifically struck by Iranian attacks) creates both supply and energy cost pressure simultaneously.

For the helium dimension: the crisis article's specific mention of helium as a commodity affected is the particular surprising inclusion that reflects the specific Gulf state helium production infrastructure whose disruption affects specific industrial and medical applications that the broader public doesn't typically associate with oil price shocks.
