Two Supertankers Ablaze in Hormuz as Oil Anxiety Grows

Supertankers Ablaze in Hormuz as Oil

Iran's Revolutionary Guards say two supertankers carrying more than two million barrels of crude each caught fire in the Strait of Hormuz after hitting mines on Saturday, 17 October 2026. The claims, reported by AFP, have not been independently confirmed. They add to a run of attacks on ships in the waterway at the centre of the Middle East war.

The strait normally carries about a fifth of the world's oil. It matters well beyond the Gulf, because oil moves global fuel prices, including the petrol and diesel South Africans pay.

Key facts

The Guards said a first supertanker, carrying over two million barrels, hit a mine and caught fire. Later they said a second one met the same fate.
The statements did not give the exact location, the tankers' flags or where their cargoes came from.
Iran has controlled the strait since the war began in late February and requires ships to seek its approval before passing.
The United States has imposed a naval counter-blockade on Iranian oil exports.
On Sunday, 11 October, six vessels were attacked in or near the strait, the most in a single day since the conflict began, according to maritime security data.

What happened

According to AFP, the Guards said the first supertanker was attempting to pass "illegally" through the strait when it struck a mine, triggering an explosion and a fierce fire. Later on Saturday, they said a second supertanker was engulfed in a blaze after hitting a naval mine, also carrying over two million barrels. The Guards said the first tanker had tried to cross with US support by switching off its tracking systems, and published a video of a vessel burning at night.

The statements did not identify the ships or say whether anyone was hurt. Because the claims come from one side in the conflict, they should be treated as unconfirmed until shipping or maritime authorities verify them.

Background and context

The conflict began on 28 February 2026, when the United States and Israel struck Iran. Tehran responded by targeting shipping and taking control of the Strait of Hormuz, a channel about 30 kilometres wide at its narrowest. Iran has told ships to use channels close to its own coast and to steer clear of southern routes near Oman, which it says are mined.

Attacks have escalated. On Thursday and Friday, Iran's army said two tankers had caught fire in what it calls a prohibited zone in the Gulf of Oman. Also on Friday, maritime monitoring agencies reported two tankers struck in Gulf waters off Saudi Arabia. The surge on 11 October, with six vessels attacked, was recorded by security firm Vanguard, the International Maritime Organization and the UK maritime agency UKMTO.

Iran's naval commander, Admiral Ali Ozmaei, warned this week that any vessel switching off its navigation systems would be treated as hostile. Washington's counter-blockade targets Iran's own oil exports.

What this means for you

Fuel prices. South Africa's petrol and diesel prices are adjusted monthly, based largely on international oil prices and the rand exchange rate. Sustained disruption in Hormuz tends to push oil prices up, which can feed into pump prices in later adjustments. No change has been announced as a result of this incident.

Everyday costs. Higher fuel costs ripple into transport, food and electricity-related costs. Keeping an eye on the monthly fuel announcement is the best early signal.

Shipping. The more dangerous the strait becomes, the more insurers and shipping companies hesitate to use it, which can tighten oil supply even without a full closure.

What happens next

Watch for confirmation or denial of the tanker incidents from maritime monitors and the US military.
Oil price movements when markets reopen will show how worried traders are.
The next monthly South African fuel price announcement will show whether any effect has reached local pumps.

Frequently asked questions

What is the Strait of Hormuz?

A narrow waterway between Iran and Oman, about 30 kilometres wide at its narrowest. About a fifth of global oil consumption normally passes through it.

Has it been confirmed that two supertankers caught fire?

Not independently. The claim comes from Iran's Revolutionary Guards, and the ships' names and flags were not disclosed.

Why is Iran controlling the strait?

Iran took control after US and Israeli strikes began in late February, and demands that ships obtain its authorisation before passing.

Will petrol get more expensive in South Africa?

Oil price rises can push fuel prices up in later monthly adjustments, but no change has been announced because of this incident.

Editor's note

The tanker claims come from Iran's Revolutionary Guards and had not been independently verified at the time of writing. This is a fast-moving situation.
