Oil prices surged and the odds of another Federal Reserve rate hike jumped after U.S. and Iranian forces traded heavy strikes over the Strait of Hormuz this weekend — and American families will foot the bill at the pump and on their mortgages.

Brent crude opened 3.5 percent higher at nearly $79 a barrel, up almost 9 percent from its prewar price, according to the New York Times. Reuters reports oil jumped about 4 percent on the session. The conflict over a waterway most Americans couldn't point to on a map is now directly threatening their paychecks: traders now price a 72 percent chance the Fed raises rates in September, up from 63 percent last week, per the CME FedWatch Tool cited by Reuters.

Ship traffic through the Strait of Hormuz — which once carried a fifth of the world's traded crude oil and natural gas — has collapsed from more than 130 vessels daily before the war to just 22 ships on Thursday, maritime data firm Kpler told the New York Times.

Over the weekend, the U.S. military struck roughly 140 targets inside Iran after Tehran attacked a container ship in the strait. Iran's Revolutionary Guard fired back at U.S. facilities across the Gulf, with missile alerts sounding in Bahrain — home to the Navy's 5th Fleet — and Kuwait intercepting hostile fire. Jordan's military said it shot down four Iranian missiles.

"We bombed the hell out of them last night," President Trump told NBC's "Meet the Press."

Iran's Revolutionary Guard claimed ownership of the strait: "The Strait of Hormuz is our territory, and we will not allow a rogue and child-killing army from the other side of the world to continue its illegal interference in it," per AP News. U.S. Central Command countered: "The Strait of Hormuz is a vital maritime corridor for global trade. Iran does not control it."

Both sides claim they control the waterway. Neither side is telling American families what this costs them.

AP framed the clash around unraveling diplomacy — the 60-day interim deal supposed to set up permanent peace talks has instead devolved into escalating strikes. Reuters focused on gold sliding and the Fed. The New York Times highlighted the shipping collapse and oil spike. What none put front and center: who authorized this escalation, what the exit strategy is, and why American taxpayers are bankrolling another Middle Eastern entanglement with no defined end.

Fed Chair Kevin Warsh delivers his first semiannual testimony to Congress this week, alongside June CPI and PPI data. Fed Vice Chair Michelle Bowman and Governor Christopher Waller also speak. Any hint of more rate hikes to fight oil-driven inflation lands on Main Street, not on the policymakers who greenlit the strikes.

UN Secretary-General António Guterres warned that "a return to full-scale hostilities would have catastrophic consequences." The catastrophe isn't abstract — it's the extra dollar at the gas station and the higher mortgage payment for families already stretched thin.

The Strait of Hormuz is 7,000 miles from the American heartland. The inflation it fuels is not. Until someone in Washington can name the U.S. interest, count the cost, and define the exit, every escalation is just another bill sent to the working class.
