Brent Crude Tops $100 as Supply Risks Lift Inflation Concerns

Brent crude rose back above $100 a barrel and West Texas Intermediate traded near $90 amid Middle East disruptions and a Gulf Coast storm. Higher crude, refining, and transport costs are pushing up gasoline and diesel prices, adding to inflation worries. Long-term Treasury yields have reached multi-decade highs as investors reassess the rate outlook.
Brent's return above $100 and WTI near $90 stem from overlapping supply threats. Attacks near the Strait of Hormuz—at least nine reported by UK officials in October—plus Middle East fighting and strikes on energy infrastructure in the Russia-Ukraine war have unsettled markets. A strengthening Gulf storm also threatens U.S. offshore oil and gas sites, prompting Chevron to remove nonessential workers.
Fuel costs are climbing: U.S. gasoline averaged $4.36 a gallon, versus $3.12 a year earlier, and diesel reached $6.30. Refining limits, costlier tanker insurance, and rerouted shipping are adding to expenses. The IEA has discussed releasing oil and diesel reserves, while the 30-year Treasury yield hit 5.72%, its highest since 2002.
Higher fuel bills could squeeze households, commuters, truckers, and small businesses, especially those already stretching budgets. Costlier diesel and shipping may feed into prices for goods and services, while elevated Treasury yields could raise borrowing costs for mortgages and corporate investment. If supply disruptions persist, consumers may face a longer period of inflation pressure and slower growth, though reserve releases or tax relief could soften near-term effects. Policymakers and investors may remain focused on energy routes and refinery capacity.
