Oil Surges Past $112 as Iran Tightens Hormuz Blockade
Brent crude settled at its highest level since 2022 after Iran declared a security zone across the Strait, choking 20% of global seaborne oil.
Brent crude settled at $112.57 per barrel Friday, up 4.2% on the session and the highest close since June 2022. West Texas Intermediate followed, finishing at $96.43.
The catalyst was Iran's Islamic Revolutionary Guard Corps declaring an expanded "security zone" across the Strait of Hormuz. The zone effectively blocks vessels bound for or departing from U.S.-allied nations, removing roughly 20% of the world's daily seaborne oil supply from normal transit routes.
This isn't posturing. Tanker tracking data shows commercial shipping through Hormuz has dropped 74% compared to pre-conflict levels. The ships that are transiting are mostly Chinese, Indian, and Russian-flagged vessels carrying oil to countries that haven't joined the U.S.-led coalition.
The $35 Swing
Oil has traded in a $35 range since the conflict began on February 28:
| Date | Brent Price | Event |
|---|---|---|
| Feb 27 | $78 | Day before strikes |
| Mar 4 | $99 | Hormuz first restricted |
| Mar 8 | $113 | Initial peak |
| Mar 23 | $89 | Trump "productive talks" |
| Mar 25 | $98 | 15-point plan submitted |
| Mar 26 | $92 | Iran rejects plan |
| Mar 27 | $112 | Security zone declared |
Every diplomatic hint pushes prices down. Every escalation spikes them back up. Traders have stopped trying to pick a direction and are simply trading the volatility.
What Changed Friday
Tehran's move went beyond the existing restrictions. The new security zone extends further into international waters and explicitly prohibits passage by any vessel that has called at a U.S., Israeli, or allied Gulf state port in the prior 30 days.
That's a de facto blockade for Western-bound oil. Saudi and UAE crude that would normally transit Hormuz must now route around the Cape of Good Hope—adding 10-14 days and roughly $5 million per voyage in shipping costs.
Insurance rates for Gulf shipping have quadrupled since February. Lloyd's of London raised its war risk premium for Hormuz transit to 3% of hull value, up from 0.5% pre-conflict. That cost gets passed through to refiners and eventually consumers.
Gasoline at the Pump
U.S. retail gasoline prices have climbed to $4.89 per gallon nationally, up from $3.12 in late February. Some West Coast markets are above $6.
The timing couldn't be worse. Spring break travel season is underway, and summer driving season starts in eight weeks. If Hormuz remains restricted through June, Goldman Sachs analysts project gasoline could hit $5.50 nationwide—levels last seen during the 2022 spike.
Fed Implications
The oil shock is rewriting the monetary policy outlook. Higher energy costs feed into headline inflation immediately and core inflation with a lag as businesses adjust prices.
The Fed held rates steady at its March meeting, citing uncertainty around the conflict. But futures markets have shifted dramatically since then. Traders now price a 52% probability of a rate hike by December—the first time that probability has crossed 50%.
"The Fed is trapped," said one rates strategist at a major bank. "Hike into a geopolitical crisis and risk recession. Hold steady and watch inflation expectations de-anchor. There's no good option."
Demand Destruction
At current prices, demand destruction becomes a factor. Airlines have already raised guidance on revenue but face margin pressure if jet fuel stays elevated. Trucking and logistics costs are rising. Consumers are driving less and spending more on necessities.
The IEA estimates global oil demand growth slows by 400,000 barrels per day for every sustained $10 increase in prices. At $112 Brent, that implies demand is already moderating versus pre-crisis forecasts.
The wild card is SPR releases. The Biden administration tapped the Strategic Petroleum Reserve aggressively in 2022. The current reserve sits at 380 million barrels, down from 638 million at its peak. There's capacity to release, but Trump has been reluctant to tap reserves while trying to negotiate from a position of strength.
Trading the Crisis
Energy stocks are the obvious beneficiaries. The XLE has gained 18% month-to-date while the S&P 500 has fallen 7%. Chevron, Exxon, and ConocoPhillips are all trading near 52-week highs.
Refiners are mixed. Marathon Petroleum and Valero benefit from elevated crack spreads but face feedstock cost pressures. Pipeline and midstream names like Enterprise Products and Kinder Morgan offer steadier exposure with less volatility.
The risk for energy longs is a sudden ceasefire. Oil could drop $30 in a week if the Strait reopens. That kind of binary outcome makes position sizing critical.
What to Watch
The April 6 deadline Trump set for "significant progress" on negotiations is the next major catalyst. Tehran's counter-proposal is reportedly in Washington's hands, but the gap between positions remains wide.
If talks collapse, $120+ oil is on the table. If they succeed, sub-$90 is possible by mid-April. There's no middle ground worth betting on right now.
