Brent crude breaks $100 as Iran conflict escalates

Brent crude exceeded $100 per barrel on Wednesday for the first time since early July. The spike follows renewed military actions in the Gulf and attacks on energy infrastructure.

Brent crude surpassed the $100 mark on Wednesday. This is the highest level since an interim peace deal was reached in early July. West Texas Intermediate prices jumped to $95 per barrel. Both benchmarks hit their peak since the summer ceasefire attempt.

The price surge followed US strikes on Iranian oil tankers. Tehran retaliated against American warships in the region. Militant groups aligned with Iran attacked energy facilities in Saudi Arabia. These events raised fears of constrained global oil supplies.

Strait of Hormuz remains a chokepoint

Traffic through the Strait of Hormuz is well below pre-war levels. The strait previously handled 20 percent of global oil and natural gas trade. Negotiations to reopen the route have stalled. The US demands pre-war passage norms. Iran insists on collecting fees from passing ships.

Russia has also cut fuel production and restricted exports. This follows repeated attacks on its refineries in Ukraine. These supply-side constraints compound the pressure from the Iran conflict. Global inventories are tightening across multiple regions simultaneously.

Consumer fuel costs rise sharply

US gasoline averages over $4 per gallon. This is more than $1 higher than a year ago. Diesel prices are nearing $6 per gallon. Diesel has already surpassed its all-time high. Americans have spent an extra $101 billion on fuel since the war began.

Higher diesel costs impact the broader economy. Trucks, ships, and factory machinery rely on diesel. Persistent fuel inflation raises the cost of transporting goods. These costs are increasingly passed on to consumers. Household budgets face significant strain from these direct and indirect increases.

Inflation risks challenge Fed policy

The Federal Reserve targets 2 percent inflation. Sustained energy shocks make this target harder to reach. Central banks usually ignore temporary price spikes. The current duration of the energy crisis is changing that calculus. Several Fed officials warned they are prepared to raise rates.

The Producer Price Index releases on Thursday. The Consumer Price Index follows on Friday. These reports precede the Fed’s rate decision next week. GN markets/inflation (en-US) notes that major banks are reevaluating their oil price forecasts. The persistence of the shock threatens to spread inflation deeper into the economy.
