"The war is hitting the global economy in cumulative waves: first through higher energy prices, then higher food prices, and finally, higher inflation," said World Bank chief economist Indermit Gill, as the organization releases its latest commodity markets outlook.

Energy costs have rocketed after US-Israeli strikes targeting Iran from February 28. Tehran retaliated by virtually blocking the Strait of Hormuz, a key waterway through which a fifth of global oil and liquefied natural gas normally transits.

Its near-total closure has hit global supplies of other important commodities, including fertilizers.

Energy costs are projected to make a 24-percent surge this year, hitting their highest level since Russia's 2022 invasion of Ukraine, the World Bank said Tuesday.

Meanwhile, fertilizer costs are set to jump by 31 percent this year due to a 60-percent surge in urea prices -- dragging fertilizer affordability to its worst since 2022 as well.

This bites into farmers' incomes and threatens crop yields, the World Bank said.

Commodity costs overall are expected to spike by 16 percent in 2026, driven by fallout from the war and metals prices.

The cost of base metals like aluminum, copper and tin are anticipated to hit all-time highs on the back of demand from industries like data centers and electric vehicles, the bank said.

Oil prices have come off recent peaks, but still remain significantly higher than before the Middle East war.

Brent oil prices are around 50 percent above pre-war costs, while US benchmark West Texas Intermediate is similarly more than 40 percent higher.

Even if the harshest disruptions end in May and shipping through the Strait of Hormuz recovers by late-2026, Brent oil is forecast to average $86 a barrel this year, up from $69 a barrel in 2025, the World Bank said.

Higher inflation is likely to push up interest rates, making debt more expensive, Gill added in a statement.

"The poorest people, who spend the highest share of their income on food and fuels, will be hit the hardest, as will developing economies already struggling under heavy debt burdens," he said.
