Here is a true breakdown of what's going on in the strait of Hormuz.
Data includes a tanker traffic summary and details about their flags.
Iran’s Foreign Minister announced on April 17 that the strait is “completely open” for all commercial vessels during the current Lebanon ceasefire, with ships required to follow Iran-coordinated routes (e.g., near Iranian islands like Larak and Hormuz).
President Trump welcomed this, but the U.S. naval blockade on Iranian ports/ships continues, war-risk insurance is still extremely high (and reviewed frequently), and shipping companies remain cautious.
As a result, it is not fully open or risk-free for normal international traffic!
Tanker Traffic Summary (as of April 18, 2026)
Normal pre-crisis levels (2025/early 2026): ~60–140 ships per day total (~95–138 average), with 50–60% being tankers/oil-product carriers. This meant dozens of tankers daily, transporting ~20 million barrels of oil and LNG daily (about 20–21% of global supply).
Since the conflict began (Feb 28, 2026–April 12): Only 279 ships total transited the strait (a >95% drop). Of these, tanker traffic was a small fraction; 22 ships (including some tankers) were attacked. Only ~45 ships passed after the April 8 ceasfire.
Recent/post-ceasefire (April 8–17): Extremely low — often 3–11 ships per 24 hours total (4–10% of normal). Very few tankers. On April 17 (the day Iran declared it open), only a handful crossed: no major oil tankers exited the Persian Gulf; one bitumen/asphalt tanker and five cargo ships headed out; a cruise ship also transited. Some groups of ~20 vessels (including VLCCs and tankers) were seen approaching but actual completed transits stayed minimal.
Last 24 hours (as of April 18): Around 6 ships total (~4–5% of normal), with very few (if any) full oil tankers. Live trackers show ~500K DWT throughput vs. normal ~10M DWT daily.
Traffic is expected to take weeks (or longer) to normalize due to insurance, scheduling, and geopolitical risks.
What Did the Tankers Contain? (Recent Examples)
Most recent transits involved crude oil (often Iraqi Basra, Saudi, UAE, or Iranian origin), petroleum products, chemicals, fuel oil, or LPG. Very Large Crude Carriers (VLCCs) can carry ~2 million barrels each.
Examples of recent/reported tankers:
VLCCs like RHN (also called Hong Lu/Dimitra II), Alicia, Agios Fanourios I — heading to/in Gulf, often to load crude (e.g., Iraq) or carrying crude/products.
Race — exited to India (crude/products).
Rich Starry, Elpis, Peace Gulf — oil/chemical tankers or medium-range, some sanctioned/Iran-linked.
Others (e.g., Serifos, Cospearl Lake, He Rong Hai) — Saudi/UAE/Iraqi crude to Asia (Malaysia, China, Myanmar).
Some were Iran-linked/sanctioned vessels carrying Iranian crude despite restrictions.
What Flags Were They Flying?
A mix of flags of convenience (common for tankers) and some national/sanctioned flags. Recent examples include:
Panama (e.g., Peace Gulf)
Liberia (e.g., Serifos VLCC)
Malta (e.g., Agios Fanourios I)
Curacao (e.g., RHN — Chinese-owned)
Pakistan, Russian, Chinese (or China-linked/owned)
Iran-linked or U.S.-sanctioned vessels (sometimes re-flagged or ghost fleet)
Many were not “standard” international commercial tankers but limited/sanctioned ones operating under special Iranian permissions or evading full blockade.
Bottom line: The strait is “open” on paper since yesterday, but real-world tanker traffic is still tiny and risky. Normal volumes (dozens of tankers daily carrying crude oil under international flags) have not resumed and likely won’t for weeks. Data comes from trackers like Kpler, LSEG, MarineTraffic, and Reuters reports.
