U.S. Blockade of the Strait of Hormuz Drives Oil Market Turmoil

Since the U.S.–Israeli strikes on 28 February 2026, Iran sealed the Strait of Hormuz, cutting off roughly 20 % of global oil and gas flows. A U.S. naval blockade maintains the closure. Brent crude peaked above $126 a barrel in early May, then settled near $113 a barrel; U.S. gasoline averaged $4.30 per gallon, up 27 cents in a week. Domestic rigs fell below pre-war levels; the Energy Department warned of a possible 2026 production dip.

Iranian on-shore storage holds about 20 days of oil; Kpler estimates 26 days before tanks fill, while Rapidan Energy adds floating storage for up to 48 days total. Tehran’s revenue loss is estimated at $170-$500 million per day. U.S. gasoline averages $4.30 per gallon and Brent peaked at $126 a barrel.

White House economic adviser Kevin Hassett said the administration is “in constant communication with oil companies” and is reviewing regulations to speed output. Treasury Secretary Scott Bessent warned Iran is “days away from running out of storage capacity.” Donald Trump called the blockade “incredible” and said it deprives Iran of oil revenue.

Senators such as Kirsten Gillibrand warned the war’s $25 billion cost is hitting U.S. drivers. Energy analyst Robin Mills (Qamar Energy) said Iran’s oil infrastructure can survive pressure, citing past shut-ins. Analyst Homayoun Falakshahi warned revenue losses of up to $250 million per day won’t appear for months, limiting the blockade’s leverage.

Storage-capacity figures differ: Kpler cites 20 days, Rapidan Energy adds floating storage for a total of 48 days. Daily revenue loss estimates range from $170 million to $500 million, with no independent verification of actual production cuts.

• “If you look at the economic stress that the Iranian people are under right now, it should be unacceptable to any civilized leader,” — Kevin Hassett, White House economic adviser.

• “The blockade is incredible. The power of the blockade is incredible. They’re not getting any money from oil, and hopefully it can be worked out very soon.” — President Donald Trump.

Higher gasoline prices strain U.S. consumers and fuel political backlash, while prolonged strait closure risks global inflation spikes and a possible recession.

The Guardian

The White House is drafting a “Maritime Freedom Construct” coalition to reopen the strait, and military planners are weighing “short and powerful” strikes. Iran’s storage runway suggests the blockade could last another 3-4 weeks before forced cuts, shaping diplomatic and market moves.
