Key Points:

Surging oil prices driven by the war with Iran are causing widespread economic ripple effects, with analysts warning that the worst impacts may still be ahead if the conflict continues for months.
The Strait of Hormuz, a critical chokepoint for 20% of global oil and LNG transit, has seen vessel traffic plummet from over 100 ships daily to fewer than five, severely disrupting supply chains and raising concerns about prolonged shortages.
U.S. gasoline prices have surged to nearly $4 per gallon, costing motorists an estimated additional $10 billion since the war began, while higher oil prices are also increasing costs across transportation, manufacturing, and raw materials sectors.
Despite ample domestic energy production insulating the U.S. somewhat, the broader economy faces a growth scare due to global inflation pressures and potential slowdowns in consumption and investment abroad triggered by rising energy costs.
Analysts warn that even if the conflict ends soon, damage to energy infrastructure and ongoing geopolitical risks in the Middle East will likely keep oil prices elevated for an extended period, with some scenarios projecting prices could spike to $200 a barrel if tensions escalate further.
