Level 1 - Absolute Beginner
The Strait of Hormuz is a narrow sea road. Many oil ships use it.
The United States says it helped about 400 ships pass in one week. It says it cleared mines from the water.
Iran says the road is still closed. It says two big oil ships hit mines on October 18 and caught fire.
President Trump says the US will not attack Iran before the November 3 election. Oil is a big worry for the world.

Level 2 - Elementary
The United States military says it helped about 400 merchant ships cross the Strait of Hormuz in the past week. US Central Command also says it has cleared mines from the waterway.
Iran tells a different story. The Revolutionary Guard says two loaded oil tankers hit mines on October 18 and caught fire. Iran also says the strait stays closed to ships it has not approved.
The numbers show the trouble. Data firm Kpler says about 8.5 million barrels of oil a day left the Gulf in the week ending October 12. That is nearly 40 percent less than before the war.
President Trump has said the US will not attack Iran before the midterm elections on November 3. Reports say he has told the military to be ready for bigger attacks afterwards.

Level 3 - Intermediate
Washington and Tehran are telling opposite stories about the same stretch of water. US Central Command says it has helped about 400 merchant vessels transit the Strait of Hormuz over the past week and that it has cleared the area of naval mines. Iran insists the strait remains closed to anyone without its permission.
The Revolutionary Guard, speaking through state media, says two supertankers, each carrying roughly two million barrels of crude, struck mines on October 18 and caught fire. It claims they used an unauthorised route. These claims come from Iranian state-linked sources and have not been independently confirmed. The US has previously said that ships have been hit by projectiles rather than mines.
The commercial impact is clear. Kpler data show Gulf exports averaged 8.5 million barrels a day in the week to October 12, nearly 40 percent below the level before the war. Shipping firms and insurers must weigh whether an American escort is worth the risk of an Iranian response.
On the political side, President Trump said the US will not attack Iran before the November 3 midterms, although reports say he has asked the military to prepare larger operations afterwards. Until then, the strait looks set to stay a contested, dangerous bottleneck.

Level 4 - Advanced
Washington and Tehran are asserting rival control over the same strip of water, and the competing accounts leave shipowners to guess which one will hold. US Central Command says it has shepherded roughly 400 merchant vessels through the Strait of Hormuz in a week and swept the channel of mines, while Iran maintains that the passage stays shut to any vessel it has not cleared.
The Revolutionary Guard, via state media, says two laden supertankers of about two million barrels each struck mines on October 18 and burned, adding that they took an unauthorised route. That account is Iranian and unverified, and American officials have attributed other recent hits to projectiles, not mines. The discrepancy matters because insurance pricing and charter decisions turn on what is actually killing ships.
The macro picture is unambiguous even if the tactical one is not. Kpler estimates Gulf exports averaged 8.5 million barrels a day in the week to October 12, nearly 40 percent beneath prewar norms, a shortfall that keeps a persistent risk premium in crude benchmarks and feeds into inflation worldwide.
Politics overlays the calculus. President Trump has said no attack will come before the November 3 midterms, yet reporting indicates he has told commanders to prepare larger strikes once voters have spoken. The strait therefore sits in an uneasy interlude: contested, partly passable and subject to abrupt escalation.
