After U.S. and Israeli strikes on Iran, Iran’s closure of the Strait of Hormuz pushed crude above $100 and sent U.S. gasoline from $2.98 to $3.94 within three weeks. The article argues the immediate question is not geopolitics but incidence: a fuel shock functions like a regressive tax that bites hardest where gasoline is a large share of income.

Using estimates from Pantheon and Oxford Economics, it notes the bottom decile spends about 4% of income on gas versus 1.5% for the top, and a year at roughly $3.70 could add about $70B to household fuel outlays. Survey splits show sentiment holding up for equity holders while stagnating for everyone else, and state price gaps amplify the hit. The piece concludes the shock is already tightening budgets and complicating the Fed’s inflation trade-off.
