Oil and Gas

The world is reckoning with the biggest oil supply disruption in history, one that has sent energy prices soaring, rattled stock markets and exposed the deep vulnerabilities of economies still hooked on fossil fuels. While millions face higher fuel and energy bills, top oil and gas companies are reportedly profiting about $30m per hour since the war began.

This week on UpFront, Redi Tlhabi speaks with renowned economist Mariana Mazzucato about what a genuine green industrial strategy looks like, why the World Bank has fallen short, and how her concept of the “common good economy” offers a new compass for governments navigating crises.

Reports of Iranian gunboats opening fire on a tanker in strait, after Tehran said it is closing the waterway until the US lifts the blockade of its ports.

Iran says it has closed the Strait of Hormuz again, calling the decision a response to a continued blockade of its ports by the United States.

The Iranian military on Saturday said control of the strategic waterway, through which 20 percent of the global oil flows, has “returned to its previous state”, with reports saying Iranian gunboats fired at a merchant vessel as it attempted to ‌cross.

The closure of the strait came hours after it was reopened, with more than a dozen commercial ships passing through the waterway, after a US-mediated 10-day ceasefire deal was reached between Israel and Lebanon.

The Islamic Revolutionary Guard Corps (IRGC) on Saturday said in a statement, cited by the Iranian media, that the ongoing US blockade of Iranian ports represented “acts of piracy and maritime theft”, adding that the control over Hormuz is “under the strict management and control of the armed forces”.

“Until the US restores full freedom of navigation for vessels travelling from Iran to their destinations and back, the status of the Strait of Hormuz will remain tightly controlled and in its previous condition,” it said.

By 10:30 GMT on Saturday, no fewer than eight oil and gas tankers had crossed the strait, but at least as many ships appeared to have turned back, having begun to exit the Gulf, the AFP news agency reported.

The toing and froing over the strait cast doubt on US President Donald Trump’s optimism the day before, that a peace deal to end the US-Israel war on Iran was “very close”.

Trump had celebrated the reopening of the strait on Friday, but warned the US attacks would resume until Iran agreed to a deal, which included its nuclear programme.

“Maybe I won’t extend it,” Trump told reporters on board Air Force One about the temporary ceasefire agreement in place. “So you’ll have a blockade, and unfortunately we’ll have to start dropping bombs again.”

Asked whether a potential deal could be made in this short timeframe, Trump said: “I think it’s going to happen.”

But Iran says no date has been agreed for another round of peace talks, accusing the US of “betraying” diplomacy in all negotiations.

The conflicting and changing reports about the strait and how much freedom ships have to transit through it have deterred many vessels from crossing, according to John-Paul Rodrigue, a maritime shipping specialist at Texas A&M University.

“Ships have been attempting transit since the announcement, but it looks like many of them are heading back because the situation is unclear,” Rodrigue told Al Jazeera. “There is contradictory information being issued by all parties.”

Reporting from Tehran, Al Jazeera’s Tohid Asadi said “uncertainty is the name of the game” as far as the Strait of Hormuz is concerned.

“Iran is looking for a comprehensive end to the war across the region, security assurances, sanctions relief, the unfreezing of frozen assets, regional relations – and on top of all of that – the nuclear dossier and Iran’s stockpile of highly enriched uranium,” he said.

“But right now, uncertainty is the name of the game. The fragile situation makes it hard to talk about the possibility of successful negotiations down the road.”

Brent crude falls more than 9 percent after Iran said it will reopen the strategic waterway, only to shut it down again over US blockade of its ports.

Oil prices have plummeted to their lowest point in weeks after Iran said the Strait of Hormuz was open for passage during a ceasefire in Lebanon, and United States President Donald Trump said he expected to ⁠reach a deal to end the war soon.

Brent crude, the international benchmark, fell more than 9 percent to $90.38 a barrel on Friday, taking it below $91 for the first time since March 10.

The plunge came after Iranian Foreign Minister Abbas Araghchi said the strait was “completely open” and would remain so for the duration of the 10-day ceasefire between Israel and Lebanon, which took effect on Friday.

Hailing Tehran’s announcement, Trump declared the waterway “ready for business and full passage,” but said the US Navy’s blockade of Iranian ports would remain in “full force” until the sides reached a peace deal.

On Saturday, however, Iran rowed back on its decision to reopen the Strait of Hormuz, warning that it would continue to block transit through the key waterway as long as the US blockade of Iranian ports remained in effect.

The announcement came after Trump said the blockade “will remain in full force” until Tehran reaches a deal with the US, including on its nuclear programme.

Roughly one-fifth of the world’s oil passes through Hormuz and further limits would squeeze already constrained supply, driving prices higher once again.

Amid the escalation, Pakistani officials say they are trying for more talks between the US and Iran ahead of the April 22 ceasefire deadline.

Meanwhile, ship tracking data displayed by MarineTraffic earlier on Saturday showed a significant uptick in vessels crossing the strait, which is located between Iran, the United Arab Emirates and Oman.

“It’s busy out there, the busiest I’ve seen it since the Strait of Hormuz was effectively closed at the beginning of the war,” Michelle Wiese Bockmann, an analyst at maritime intelligence firm Windward, said in a post on X.

“Last night there were few ships taking the risk but overnight there seems to have been a change.”

While Iran allowed a limited number of vetted ships to transit the waterway since the start of the war, traffic has remained at a trickle compared with pre-conflict levels.

The near-total closure of the strait has triggered one of the worst energy shocks in history, driving up fuel prices and prompting governments to roll out emergency measures.

Oil prices have swung wildly since the US and Israel launched strikes on Iran on February 28, hitting a post-conflict peak of $119 a barrel on March 19.
