Oil at $100+, Mortgages at 6.58%: The Iran War Tax You're Paying Every Month in 2026

# Oil at $100+, Mortgages at 6.58%: The Iran War Tax You're Paying Every Month in 2026

> **Quick answer:** Since the U.S.-Israel war on Iran began on February 28, 2026, the average American family is paying an estimated $400 to $500 more per month due to higher gas prices, elevated mortgage rates, rising food costs, and indirect insurance and shipping surcharges — a financial burden economists are calling a regressive "war tax" that falls hardest on those who can least afford it.

Nobody sent you a bill. There was no vote on it in Congress. But since February 28, 2026 — the day U.S. and Israeli forces launched strikes on Iran — your household has been paying a tax you never agreed to. It shows up at the pump. It shows up on your mortgage statement. It shows up in the grocery aisle and in your utility bill. Add the pieces together and the Iran war tax on the average American family is running somewhere between $400 and $500 per month. This article builds that number from the ground up, category by category.

## What the Iran War Did to Oil — and Why Everything Else Followed

The Strait of Hormuz is a 21-mile-wide chokepoint through which roughly one-fifth of the world's oil passes every single day. When U.S. and Israeli strikes on Iran began on February 28, 2026, traffic through the strait effectively halted. Brent crude, which had been trading around $65 per barrel in early February, surged to a peak of $119.48 per barrel in March before settling near $100 to $105 as of mid-May.

That 54% price spike in crude is the root cause of almost every other number in this article. Oil is not just what goes in your gas tank — it is the feedstock for plastics, the fuel for every truck that delivers every product you buy, the input for fertilizers that grow the food on your plate, and a key driver of the inflation expectations that set mortgage rates.
