Brent crude surpassed $100 per barrel on Wednesday. This is the first time since early July that prices hit this level. West Texas Intermediate reached $95 per barrel. These are the highest levels since the interim peace deal in summer.

Brent crude surpassed $100 per barrel on Wednesday. This is the first time since early July that prices hit this level. West Texas Intermediate reached $95 per barrel. These are the highest levels since the interim peace deal in summer. The price spike followed US strikes on Iranian tankers. Iran-allied groups also attacked Saudi energy facilities.

The US destroyed several Iranian oil tankers over the weekend. This was a response to attempted attacks on American warships. Supply constraints are intensifying. Traffic through the Strait of Hormuz remains low. This cuts off a major portion of global oil and gas supply.

Strait of Hormuz remains a key bottleneck

Reopening the Strait of Hormuz is central to resolving the conflict. Before the war, 20% of the world's oil and gas passed through this route. The US demands pre-war norms for passage. Iran insists on collecting fees from ships. Negotiations have collapsed after several rounds of talks.

Russia has also cut back on fuel production. It restricted exports after attacks on its refineries. This adds to the pressure on global oil supplies. The combined effect of these actions is squeezing the market.

Fuel costs drive consumer inflation

US gasoline prices are well over $4 per gallon. This is more than $1 higher than a year ago. Diesel prices are nearing $6 per gallon. This surpasses all-time highs. Americans have spent an extra $101 billion on fuel since the war started.

Higher diesel prices affect the broader economy. Diesel powers trucks, ships, and factory machinery. Rising costs are passed on to consumers. This creates a ripple effect across production and shipping sectors.

Fed faces harder inflation fight

Sustained energy shocks challenge the Federal Reserve's 2% inflation target. Central banks usually ignore temporary energy spikes. Persistent pressure risks spreading to other sectors. Fed officials warn of potential rate hikes if inflation does not slow.

Two key inflation reports are due this week. The Producer Price Index is released on Thursday. The Consumer Price Index follows on Friday. These data points will inform the rate decision next week. The source GN markets/inflation (en-US) notes the heightened risk.
