Government borrowing costs reached their highest level since 2007 as long-term Treasury yields surged to 5.32%, while U.S. officials announced plans to increase domestic fuel refinery output amid ongoing disruptions to global oil supplies.
The 30-year Treasury yield climbed to its peak in nearly two decades before slightly easing, reflecting investor concerns over persistent inflation and the prolonged conflict in Iran. The surge in borrowing costs threatens to elevate mortgage and credit card interest rates, as long-term bond yields influence consumer loan pricing. Major stock indexes responded with declines: the Dow Jones Industrial Average fell 0.03%, the S&P 500 dropped 0.4%, and the Nasdaq declined 1%.
Global oil prices exceeded $91 per barrel on August 17, a 30% increase since late February when military operations between the U.S. and Israel against Iran disrupted shipping through the Strait of Hormuz. The average price of gasoline reached $4.06 per gallon, up from $2.98 before the conflict, according to AAA data. The Strait of Hormuz, a critical route for 20% of global oil supply, remains partially closed due to ongoing tensions and failed negotiations to restore safe passage.
U.S. Announces Measures to Increase Fuel Production
Energy Secretary Chris Wright stated the U.S. government will unveil steps to help refiners boost fuel production as gasoline prices remain elevated. Speaking in Midland, Texas, Wright noted that while U.S. refineries are operating at record-high levels, production in the Middle East has declined. He emphasized the administration’s goal to further ramp up refinery output and engage with industry leaders to identify additional measures.
Gasoline prices have stabilized below the $5.02 peak recorded in June 2022 following Russia’s invasion of Ukraine but remain significantly higher than the $2.98 average on February 28, the day military operations against Iran began. The national average for regular gasoline was $4.06 per gallon on August 17, up from $3.98 a month prior.
Political Responses to Rising Fuel Costs
President Donald Trump framed the increase in gasoline prices as a necessary trade-off to prevent Iran from acquiring nuclear weapons. During an August 14 rally in Garden City, New York, he stated, “For you to pay a tiny little bit more for your gasoline, just remember you’re doing it so that a very evil country cannot have… a nuclear weapon.” Trump added, “So remember that when you have to pay a little bit more, you’re at $4, it’s okay. ... I’ll never apologize, I did the right thing.”
Negotiations between the U.S. and Iran to fully reopen the Strait of Hormuz have stalled, with no immediate resolution in sight. The closure of the strait, a vital oil transit route, continues to strain global energy markets and contribute to elevated fuel prices worldwide.
