BREAKING · Iran re-closes Hormuz — IRGC gunboats fire on two Indian tankers — India summons ambassador — ceasefire expires Apr 21 · Apr 18, 2026
Global shipping crisis · Day 50

Hormuz is closed again.
IRGC opened fire on Indian ships.

Iran reversed its "completely open" declaration within 24 hours. On April 18, the IRGC said the strait has "returned to its previous state" — and sent gunboats to back it up, firing on two Indian-flagged tankers (Sanmar Herald and Jag Arnav) that had received prior Iranian clearance. India summoned Iran's ambassador. Brent is rebounding toward $96 after briefly falling on the short-lived "open" announcement. The ceasefire expires April 21 — three days away. Pakistan is pushing for a second round of talks.

Brent crude price
~$96↑
Rebounding toward $96 after Iran re-closed Hormuz and fired on Indian ships Apr 18. Had briefly fallen on Apr 17 "open" announcement before reversing sharply within 24 hours.
Cost to Iran · blockade
$435M
Per day in economic damage, per CENTCOM estimates. ~90% of Iran's economy moves by sea. Iran is now threatening to extend disruption to Red Sea shipping in retaliation.
Current Status
The strait is now closed from both sides
Apr 18, 2026
🚢
Iran demanding permission for each ship
Despite ceasefire terms, Iran is requiring individual ship clearance before transit. "Let's be clear: the Strait of Hormuz is not open. Access is being restricted, conditioned and controlled," said Sultan Al Jaber, ADNOC CEO, on April 9.
Critical
💰
$1M+ toll per transit, reportedly in crypto
Iran is charging over $1 million per ship to transit — a figure the US has explicitly rejected. Trump's White House says the strait must open "without limitation, including tolls." The toll demand is a direct ceasefire sticking point.
Critical
💣
Mine risk is now shaping military and commercial decisions
U.S. officials said on Apr 11 that military assets were searching for mines in and around the strait. Even without confirmed detonations, the threat has kept commercial traffic thin and reinforced shipowners' reluctance to re-enter normally.
Unconfirmed
📋
Insurance: war risk cover near-unavailable
War risk premiums surged from 0.125% to ~1% of ship value per transit — from roughly $125K to $1M+ for a $100M tanker. Many major insurers have exited the Gulf entirely. Without coverage, shipowners face liability exposure they cannot absorb.

IRGC fires on Indian tankers — India summons Iran's ambassador
April 18: IRGC gunboats opened fire on Indian-flagged tankers Sanmar Herald (2M bbl Iraqi crude) and Jag Arnav in the strait — both vessels had received prior Iranian clearance. Dramatic audio captured crew: "You gave me permission… You are firing now!" India's Foreign Secretary summoned Iran's Ambassador and conveyed "deep concern." This is the first confirmed attack on third-country vessels since the war began.

Ceasefire expires April 21 — 3 days left — no extension confirmed
Pakistan is pushing for a second round of US-Iran talks in Islamabad before the April 21 deadline. No date has been set. Iran reversed its "open" declaration within 24 hours of making it. A US official said Washington has not formally agreed to any extension. Key sticking points remain: enrichment duration (20 yr vs 5 yr), proxy funding, and who controls Hormuz and on what terms.

Iran reversed "open" within 24 hours — fired on Indian ships — deadline in 3 days
On April 17, Iran declared Hormuz "completely open" — oil fell 11%. Within 24 hours, Iran reversed: IRGC said the strait has "returned to its previous state." Gunboats fired on two Indian tankers that had prior clearance. The ceasefire now expires April 21. Pakistan is pushing for a second Islamabad round but no date has been set and no extension is confirmed. Iran's FM says the blockade is a "violation" of the ceasefire. The US has not formally agreed to any extension.
US position

Blockade stays until a peace deal — Hegseth: "as long as it takes." Washington says it has not formally agreed to any ceasefire extension. Three irreconcilable issues remain: enrichment (20-year halt demanded), proxy funding (Hezbollah/IRGC), and Hormuz control terms. The US calls Iran's IRGC-permission regime a non-starter.

Iran position

Iran's FM calls the US blockade a "violation" of the ceasefire. Iran reversed its "open" declaration and re-closed the strait after the US refused to lift the blockade. IRGC fired on Indian ships to enforce the closure. Iran studying "fresh US proposals" per Irish Times. Counter-offer: 5-year enrichment pause, enrichment rights "indisputable."

Traffic Collapse
Ships per day through Hormuz
From a baseline of ~100–138 vessels daily, traffic collapsed to near-zero when Operation Epic Fury began February 28. Forty-three days into the war, the corridor is still closed to the vast majority of commercial shipping.

Energy Markets
The price shock so far
Oil markets have been in crisis mode since Feb 28. Prices spiked to $126/bbl at peak, briefly fell on ceasefire news, then climbed again as the closure persisted. The collapse of Pakistan talks and the US naval blockade announcement are expected to drive another sharp leg higher. Goldman warns above $100 for all of 2026 if the closure holds another month.
Brent Crude
~$96↑
Rebounding after Iran re-closed strait

Oil fell 11% on Apr 17 "open" announcement — then reversed sharply as Iran re-closed Apr 18 and fired on Indian tankers. Brent rebounding toward $96. Extreme volatility from 24-hour policy flip.

WTI Crude
~$91↑
Recovering from brief Apr 17 dip

WTI whipsawed: dropped to ~$88 on Iran "open" claim, then recovered as strait re-closed. Supply reality unchanged — blockade and IRGC enforcement both active.

LNG Spot (Asia)
$38
+85% since Feb 28 (est.)

Qatar's LNG exports — ~25% of global supply — transiting through Hormuz are severely disrupted. Asian buyers scrambling for spot cargoes.

War risk insurance
~1%
Was 0.125% pre-war

As a % of ship value per voyage. For a $100M VLCC: cost went from ~$125K to ~$1M per trip. Many insurers have exited entirely.

Cape of Good Hope diversion
+14d
Extra transit time

Ships rerouting around southern Africa add 10–14 days and significant fuel cost. Many tankers have chosen this over the risk of Hormuz.

Goldman 2026 forecast
$100+
If closed another month

Goldman Sachs warns that one more full month of Hormuz closure would keep Brent above $100/bbl for the remainder of 2026.

Who Depends on Hormuz
Energy exposure by country
The strait carries roughly 20–21 million barrels of oil per day in normal times — about 20% of global oil trade and 25% of seaborne oil. These are the nations most exposed to the blockade.
🇨🇳
China
~50%
of oil imports via Hormuz
China is the world's largest crude importer and the biggest single buyer of Gulf oil. Strategic reserves buying time, but growing pressure.
🇮🇳
India
~60%
of oil imports via Hormuz
India's economy runs heavily on Gulf crude. Refinery intake has already dropped. Fuel prices rising at the pump.
🇯🇵
Japan
~90%
of oil imports via Hormuz
Japan sources nearly all its oil from the Middle East and it transits Hormuz. Also depends on Qatari LNG now blocked. Among the most exposed nations.
🇰🇷
South Korea
~80%
of oil imports via Hormuz
Korea relies heavily on Middle Eastern crude and Qatari LNG. Shipbuilders and refiners both squeezed simultaneously.
🇪🇺
European Union
~15%
of oil supply at risk
Less directly exposed than Asia but significant LNG reliance on Qatar. Global price surge is felt across all EU economies regardless of direct Hormuz exposure.
🇺🇸
United States
~5%
direct import exposure
US is net oil exporter and less directly exposed, but global price spike flows through. US SPR drawdowns ongoing. Military in the region driving crisis.
