Oil Hits $100+: How the Iran War
Is Reshaping Global Energy

The conflict began on February 28, 2026, when the United States and Israel launched joint strikes on Iran, codenamed "Operation Epic Fury." The operation targeted Iranian military infrastructure, nuclear facilities, and leadership — including a decapitation strike that killed Supreme Leader Ali Khamenei. Iran retaliated with missile and drone strikes against US and Israeli targets, Gulf states hosting US forces, and critically, commercial shipping in the Strait of Hormuz.

The Strait of Hormuz is a narrow maritime corridor connecting the Persian Gulf to the Gulf of Oman. Before the war, approximately 20 percent of global petroleum consumption and 19 percent of global liquefied natural gas moved through this single chokepoint daily. Iran's Revolutionary Guard declared the strait closed and attacked several tankers, and insurance costs for passage skyrocketed overnight. Shipowners refused to risk vessels and crew.

The consequences cascaded rapidly. Iraq, the second-largest OPEC producer, saw output from its three main southern oilfields collapse 70 percent to 1.3 million barrels per day — down from 4.3 million before the war. The UAE began carefully managing offshore production, and Kuwait started shutting in production. Saudi Arabia, the world's largest oil exporter, faced the same storage capacity crisis as tankers with nowhere to go piled up crude.

Simultaneously, refineries and LNG facilities across Bahrain, Kuwait, Qatar, Saudi Arabia, and the UAE were targeted in attacks largely attributed to Iran. Qatar halted all gas production after Iranian drones attacked Qatari gas facilities on March 2, causing European natural gas prices to nearly double.

The price action since February 28 has been staggering. Oil futures recorded their biggest weekly gain in trading history dating back to 1983, surging 35 percent in a single week. Here is how prices evolved:

The most immediate way consumers feel the Iran war oil prices 2026 crisis is at the pump. US gasoline prices have surged approximately 20 percent since the war began, and the knock-on effects are spreading across the entire economy.

The PBS News reported that if oil stays near $100 per barrel, gas could approach $4 per gallon nationally by next week. Mark Zandi, chief economist at Moody's Analytics, warned that sustained $100 oil would cause inflation to accelerate, cutting into consumer spending and threatening GDP and employment.

Beyond the Pump: The Cascading Cost Chain

Gas prices are only the beginning. As CNN reported, every sector reliant on fuel transport faces cost pressure. Fuel accounts for 50–60 percent of total shipping operating costs. When fuel prices surge, shipping slows, surcharges rise, and goods become more expensive across the board.

Fertilizer prices are particularly vulnerable. About one-third of the global fertilizer trade passes through the Strait of Hormuz, and the Gulf countries supply 45 percent of global sulfur. This disruption arrives just ahead of the Northern Hemisphere spring planting season, threatening agricultural input costs for months to come.

According to EY-Parthenon economist Gregory Daco, the fuel price shock could push monthly US inflation to 1 percent in March — the highest monthly increase in four years. On an annual basis, this would push inflation toward 3 percent, well above the Federal Reserve's 2 percent target.

On March 11, the International Energy Agency agreed to release 400 million barrels from emergency stockpiles — the largest such action in the IEA's 52-year history. The 32 member countries collectively hold 1.2 billion barrels in reserve.

However, the math is concerning. The IEA's own monthly report estimated that the Strait of Hormuz closure is removing approximately 15 million barrels of crude oil and 5 million barrels of other petroleum products from global markets daily. At that rate of disruption, the entire 400 million barrel reserve would be consumed in roughly 26 days.

Energy Secretary Chris Wright acknowledged that the US portion of the release would take 120 days to complete. Industry analysts noted it could be 60–90 days before the oil meaningfully reaches the market. This is not the immediate relief traders were hoping for.

Goldman Sachs (March 12, Reuters)

Goldman Sachs raised its Q4 2026 Brent forecast to $71 per barrel (from $66), assuming 21 days of Strait of Hormuz flows at 10 percent of normal levels followed by a 30-day gradual recovery. The bank expects Brent to average $98 in March and April before moderating. In an upside risk scenario where disruptions persist longer, the bank warned Brent could reach $135.

US Energy Information Administration (March 10)

The EIA raised its 2026 Brent average forecast to $79 per barrel — a dramatic increase from the $58 forecast issued just one month earlier. The agency expects US crude production to average 13.6 million barrels per day in 2026, about half a million higher than previously expected, as higher prices incentivize domestic drilling.

Rapidan Energy Group

Bob McNally, president of Rapidan Energy, called this the biggest supply disruption in the history of the oil industry. His firm warned that if current conditions persist for two months, Brent could test $120 on a sustained basis — levels not seen since the Russia-Ukraine conflict peak.

For small and mid-sized enterprises, the Iran war oil crisis creates compounding cost pressures that larger corporations can absorb more easily. As CNBC's analysis noted, businesses are already absorbing tariff costs from the previous year and have limited margin to pass along additional transportation cost increases.

Direct Fuel Costs

Any business running a delivery fleet, service vehicles, or equipment is seeing immediate cost increases. The 20 percent surge in fuel prices translates directly to higher operating costs. Use the calculator above to model your fleet exposure.

Supply Chain and Shipping Surcharges

Fuel accounts for 50–60 percent of maritime shipping operating costs. Shipping companies will pass these increases to customers through fuel surcharges. If you import goods — especially from Asia (75 percent of Gulf oil exports go to China, India, Japan, and South Korea) — expect cost increases in the pipeline.

Inflation and Consumer Spending

The National Retail Federation expects higher gas prices to affect consumer spending, particularly among lower-income shoppers. Discretionary spending categories — restaurants, entertainment, travel — are the first to get cut when fuel costs rise. Service businesses in these sectors should prepare for reduced foot traffic.

Interest Rate Uncertainty

The Federal Reserve faces a difficult position. Higher oil prices are an inflationary shock, but they also slow economic growth. The Center for American Progress analysis noted that this "puts the Fed in a no-win situation" — with rate decisions likely frozen until the geopolitical picture clarifies. Mortgage rates have already ticked up, with 30-year fixed rates rising to 6.14 percent from 5.99 percent.

The critical variable remains whether the Strait of Hormuz reopens. As energy analyst Sasha Foss of Marex noted, the IEA stockpile release buys a few days, but the fundamental resolution depends entirely on the end of active conflict and the resumption of tanker traffic.

For consumers: monitor gas prices weekly, consider consolidating trips, and budget for 10–20 percent higher fuel costs through at least Q2. For businesses: model fuel surcharge exposure now, review contracts with fuel escalation clauses, and assess supply chain alternatives for Asia-sourced goods.

For investors: the EIA now forecasts US crude production averaging 13.6 million barrels per day in 2026, with higher prices incentivizing domestic drilling. Renewable energy stocks have also seen renewed interest, as the crisis highlights the vulnerability of fossil fuel supply chains to geopolitical disruption.
