Trump’s Hormuz blockade enters third week as oil holds above $110, neither side shows retreat

The U.S. Naval blockade of Iranian ports, now in its third week, has pushed Brent crude above $112 per barrel while failing to force Tehran’s capitulation, creating a dual maritime stranglehold where both Washington and Iran restrict passage through a chokepoint carrying 20% of global seaborne oil. President Trump’s 13 April order deployed over 10,000 personnel and more than a dozen warships to enforce what the administration frames as economic pressure, but the operation has evolved into an indefinite military commitment with no clear exit strategy and cascading effects across energy markets, supply chains, and the global economy.

Blockade enforcement gaps emerge as oil markets price in prolonged disruption

The U.S. Navy intercepted 23 vessels in the blockade’s first week, according to official statements reported 18 April. Yet by 20 April, Lloyd’s List documented at least 26 ships bypassing the blockade line in both directions. Trump claims the operation costs Iran $500 million daily, but enforcement gaps suggest the stranglehold is less airtight than White House rhetoric implies.

Brent crude rose to $106.80 per barrel on 24 April, per Al Jazeera, before topping $112 the following day. The strait normally carries 20-25% of global seaborne crude and 20% of LNG trade, according to the U.S. Energy Information Administration. Tanker traffic collapsed from 138 vessels daily pre-war to single digits on most days in April. Alternative pipelines — Saudi Arabia’s Red Sea route, UAE’s Fujairah terminal, Iraq’s Kirkuk-Ceyhan — offer combined capacity of ~9 million barrels per day, less than half the ~20 million bpd that normally transits Hormuz.

The physical constraint is driving structural price support. Gas prices in the U.S. surged $1.16 per gallon since the war began 28 February, reaching $4 per gallon by 31 March — a 30% jump reflected in Canadian markets as well, according to CBS News. Panama Canal traffic has surged from 34 ships daily in January to 50 ships as of 28 April as shippers reroute around the Hormuz bottleneck.

Iran earns billions despite blockade, currency collapse continues

Iran exported 55.22 million barrels between 15 March and 14 April at prices not falling below $90 per barrel, netting an estimated $4.97 billion at conservative pricing, according to Al Jazeera analysis. The country’s total exports in March reached 1.84 million barrels per day, up from a 1.68 million bpd average in 2025. Yet the IMF projects the Iranian economy will shrink 6.1% in 2026 with inflation hitting 68.9%, while the rial has collapsed to approximately 1.32 million per USD, per CNBC reporting.

The economic pain is real but asymmetric. Over 220,000 Indian nationals have been repatriated from the Gulf since the war outbreak, driving 14% real estate growth in secondary Indian cities as skilled professionals relocate. European manufacturers face 30% energy surcharges, and the European Central Bank warned that prolonged conflict will trigger stagflation, with Germany and Italy facing recession risk by year-end.

Diplomatic stalemate hardens as nuclear demand blocks exit ramp

Iran proposed reopening the Strait of Hormuz in exchange for lifting the U.S. blockade while postponing nuclear negotiations. The Trump administration signaled rejection within 24 hours. Secretary of State Marco Rubio dismissed the offer, stating: “What they mean by opening the straits is, ‘Yes, the straits are open, as long as you coordinate with Iran, get our permission, or we’ll blow you up and you pay us'”.

The talks in Islamabad on 11-12 April ended without agreement after Trump posted on Truth Social that “the meeting went well, most points were agreed to, but the only point that really mattered, NUCLEAR, was not”. Vice President JD Vance, who led the U.S. delegation, framed the issue bluntly: “The simple question is, do we see a fundamental commitment of will for the Iranians not to develop a nuclear weapon? We have not seen that yet.”

Trump extended the ceasefire indefinitely on 24 April after initially setting expiration for 22 April, but the blockade remains in force. The Council on Foreign Relations notes the U.S. has deployed three aircraft carrier strike groups to the Middle East for the first time in decades, alongside minesweepers conducting clearing operations. The naval commitment signals willingness to sustain operations for months, not weeks.

What to watch

Enforcement sustainability will determine whether the blockade achieves strategic goals or devolves into indefinite standoff. The U.S. Navy’s ability to maintain three carrier strike groups in theatre for an extended period has operational limits, while Iran’s revenue losses — genuine but not crippling given $4.97 billion earned in the month before full blockade enforcement — may allow Tehran to outlast Washington’s political timeline.

The nuclear demand remains the immovable obstacle. Until Washington lowers that bar or Tehran capitulates, the dual blockade appears set to continue — sustaining triple-digit oil, bleeding both economies, and testing which side’s political structure can endure economic pain longer. With Trump having extended the ceasefire indefinitely rather than resuming kinetic operations, the conflict has shifted from battlefield intensity to grinding economic attrition. Neither side has shown willingness to blink first.
