Energy and Borrowing Costs Rise as Iran Conflict Escalates

In July 2026, a series of reports documented rising energy and borrowing costs in the United States tied to an escalating military conflict involving Iran. On July 8, oil prices surged and stocks fell after President Trump stated that an Iran ceasefire was 'over,' according to NBC News, reversing weeks of declining gas prices. By July 20, CBS News and The New York Times both reported that the U.S. national average gas price had crossed $4 a gallon for the first time in over a month, with CBS citing AAA data showing an average of $4.003. The New York Times noted this followed a brief period of relief after the U.S. and Iran had signed a deal intended to reopen the Strait of Hormuz. The conflict continued to intensify through late July. On July 23, BBC News reported that Brent crude oil prices reached $100 a barrel for the first time since May, rising more than 6% in a single day as war in the Middle East continued. By July 30, NPR reported that the 30-year fixed-rate mortgage in the U.S. climbed to an average of 6.66%, its highest level in a year, attributing the rise to a combination of war-related uncertainty and inflation concerns. The reports collectively describe a monthlong escalation from a ceasefire breakdown to compounding economic effects across oil markets, fuel prices, and consumer borrowing costs. It remains unresolved how directly the mortgage rate increase was tied to the Iran conflict versus broader inflation trends, as NPR cited both factors without specifying their relative weight. The precise status of the Strait of Hormuz agreement following the ceasefire's collapse and whether it remained partially in effect was not clarified across the available reports.
