  • There are growing fears that the war in Israel will escalate and the US and Iran get more involved.

  • The impact on oil prices would be enormous with one prediction of $150 per barrel.

  • A surge in oil prices could undo the fight against inflation and cause prices to soar again.

While the most pressing concern in Israel is the immediate human toll as thousands have died in the conflict with Hamas, the war also has a chance of disrupting the global economy.

In the latest estimates, more than 4,100 people have died since Hamas' terrorist attacks earlier this month and Israel's subsequent war against the militant group.

As the war in Israel rages on, there are growing fears it will escalate into something much bigger, and the ripple effect could undo any hopes for the US economy to avoid a recession.

International Monetary Fund managing director Kristalina Georgieva expressed concern on Thursday over how global oil markets would be impacted by the war. Specifically, if the US and Iran were to get more directly involved, there would be significant disruptions to oil supply.

This was echoed by Bloomberg Economics, who said the big fear for the global economy is if Israel ends up in direct conflict with Iran, which could pull the US more directly into the conflict. If that were to happen, they predict that oil prices would skyrocket more than 70% to $150 per barrel from just under $90 we have now.

An estimated 20-30% of global oil supply passes through the Strait of Hormuz, which is controlled by Iran. If Iran were to get directly involved in the war, there would be increased pressure for the US and other Western nations to increase sanctions on Iran, which could then turn around and close the strait, disrupting global oil supplies and elevating prices.

Bloomberg does not think the impact on oil prices would be as severe as the quadrupling seen during the "Oil Shock" in 1973 when Arab states imposed an embargo in retaliation for US support of Israel during the Yom Kippur War. However, they believe it could be in line with the surge seen after Iraq invaded Kuwait in 1990, but with a much higher starting point this time around.

The impact would be enormous

A price of $150 per barrel would be the highest in over a decade.

Bloomberg's economists surmise that such a surge in oil prices alone could cause global GDP growth to fall from the 3.0% predicted for 2023 to 1.7%, a drop in about $1 trillion of world output.

If oil prices do surge, inflation could spike again in the US, as they directly impact gas prices for the American consumer to fill their cars and travel on planes. It would also raise the cost of shipping goods, affecting supply chains and causing prices to soar.
