4 ways the war with Iran is doing damage to the global economy

The Strait of Hormuz, a key global shipping route, is closed off causing energy and fertilizer prices to go up.

The war with Iran is doing collateral damage to the world economy.

The conflict is driving up energy and fertilizer prices; threatening food shortages in poor countries; destabilizing fragile states such as Pakistan; and complicating options for the inflation fighters at central banks like the Federal Reserve.

Causing much of the pain: the Strait of Hormuz — through which a fifth of world’s oil passes — was effectively shut down after the U.S. and Israel launched missile strikes Feb. 28 that killed Iranian leader Ayatollah Ali Khamenei.

“For a long time, the nightmare scenario that deterred the U.S. from even thinking about an attack on Iran and which got them to urge restraint on Israel was that the Iranians would close the Strait of Hormuz,” said Maurice Obstfeld, a senior fellow at the Peterson Institute for International Economics and former chief economist at the International Monetary Fund. “Now we’re in the nightmare scenario.”

With a key shipping route cut off, oil prices have surged — from less than $70 a barrel on Feb. 27 to a peak of nearly $120 early Monday before settling closer to $90. They’ve taken gasoline prices with them.

According to AAA, the average price of U.S. gasoline has shot up to $3.48 a gallon from just under $3 a week ago. Prices could be felt even more significantly in Asia and Europe, which are more dependent on Middle Eastern oil and gas than the United States.
