Strait of Hormuz Threat Pushes Crude Past $100, Brent to $122
Iran tensions have driven WTI crude from $89 to $105 in one week and Brent to $122. Gas prices hit $3.99, up 36% from $2.94 five weeks ago. The Strait of Hormuz carries 20% of global oil supply.
Escalating U.S.-Iran tensions over the Strait of Hormuz have driven a sharp rally in global crude oil markets. West Texas Intermediate surged from $89.33 to $104.69 between March 23 and March 30 -- a 17.2% weekly gain. Brent crude, the global benchmark, rose even faster, climbing from $103.79 to $121.88 over the same period.
The Strait of Hormuz, a 21-mile-wide waterway between Iran and Oman, carries approximately 20% of global petroleum supply. Any disruption to traffic through the strait would immediately constrain supply to global markets.
Crude Oil Prices (March 23-30, 2026)
| Date | WTI Crude | Brent Crude | WTI Daily Change |
|---|---|---|---|
| March 30 | $104.69 | $121.88 | +3.4% |
| March 27 | $101.26 | $121.47 | +5.3% |
| March 26 | $96.18 | $113.39 | +5.1% |
| March 25 | $91.51 | $109.14 | -1.8% |
| March 24 | $93.18 | $108.42 | +4.3% |
| March 23 | $89.33 | $103.79 | -- |
The WTI-Brent spread widened to $17.19 per barrel, up from $14.46 a week earlier. A widening spread typically indicates global supply risk concentrated outside the U.S., consistent with a Hormuz-related disruption scenario.
Gas Prices at the Pump
The crude rally is flowing directly to consumers. The national average for regular gasoline hit $3.99 per gallon for the week ending March 30, up from $2.937 just five weeks earlier -- a 35.9% increase.
| Week Ending | Regular Gas | Weekly Change |
|---|---|---|
| March 30 | $3.990 | +0.7% |
| March 23 | $3.961 | +6.5% |
| March 16 | $3.720 | +6.2% |
| March 9 | $3.502 | +16.2% |
| March 2 | $3.015 | +2.7% |
| February 23 | $2.937 | -- |
What Outlets Are Covering
Multiple outlets are covering the U.S.-Iran confrontation from a political and diplomatic angle:
- Financial Times: "Donald Trump says US could destroy Iran 'in one night' as he demands opening of Strait of Hormuz"
- CNN: "Trump says 'entire country' of Iran could be taken out if no deal is reached by tomorrow"
- Reuters: "Iran rejects ceasefire in response to proposals"
- PBS: "Iran rejects latest ceasefire proposal as Trump deadline approaches"
The primary-source data tells the energy story beneath the headlines: crude has already priced in significant disruption risk, and consumers are paying for it at the pump.
Context
The last time WTI sustained prices above $100/barrel was during the 2022 Russia-Ukraine energy crisis. The current Brent price of $121.88 exceeds those 2022 peaks.
The Strait of Hormuz disruption scenario is the most significant oil supply risk in global markets. Saudi Arabia, Iraq, Kuwait, the UAE, and Qatar all export through the strait. An actual closure -- even temporarily -- would likely push Brent above $150 and trigger gasoline rationing in import-dependent economies.
