How a cornered Iran could wreak havoc on global oil trade
Article content
(Bloomberg) — US airstrikes on Iranian nuclear facilities are sharpening the focus on one option Iran has yet to really deploy in the conflict: disrupting regional oil trade, especially through the critical Strait of Hormuz.
Article content
Iran has over the years threatened multiple times to shut the strait — a narrow stretch of water through which a fifth of the world's oil supply flows each day. But in practice, Tehran has numerous less-drastic options at its disposal to calibrate a response that hurts its enemies while limiting the impact on allies like China, its biggest oil buyer.

A full closure of Hormuz for more than a few hours or days is a nightmare scenario that many observers think improbable. It would choke off flows and spike crude prices — JPMorgan & Co. analysts said by almost 70% — fueling global inflation and weighing heavily on growth.
Article content
Up to Friday, oil shipping from the region, and indeed through Hormuz, had been relatively unscathed by the conflict. Shipments from Iran itself have surged, and oil tanker activity through the Strait of Hormuz remained largely steady. Still, Greece's shipping ministry on Sunday advised the nation's vessel owners to review the use of the strait.
Article content
If it chooses to target oil in its retaliation against the US strikes, Iran's coastline onto Hormuz gives Tehran an array of options, from lower-impact harassing of ships in the region, to the more extreme alternatives: attacking tankers with drones, mines or bombs to the point that the strait becomes impassable for commercial trade.

'If Iran were to decide to begin to take action in the Straits of Hormuz, there's a wide range of things that can look like,' Daniel Sternoff, non-resident fellow at the Columbia University's Center on Global Energy Policy, said on the center's podcast before the US attack happened. 'We can kind of draw a huge set of scenarios and unknowns which have all sorts of consequences.'
Article content
Still, Iran may ultimately avoid actions that impede oil flows — recent history is littered with examples where supply threats came to nothing.
Article content
In whatever it does, Tehran will have to weigh the possibility of retaliation against its own energy infrastructure and the possibility that it could upset China if flows got disrupted. It will also have to consider the potential for retaliation against its own shipments, another important source of oil for China.

Shares dip in Asia, oil up as world awaits Iran response
Wall Street share futures slipped on Monday and oil prices briefly hit five-month highs as investors anxiously waited to see if Iran would retaliate to U.S. attacks on its nuclear sites, with resulting risks to global activity and inflation. Early moves were contained, with the U.S. dollar getting only a minor safe-haven bid and no sign of panic selling across markets. Oil prices were up around 2%, but already well off their initial peaks. Optimists were hoping Iran might back down now its nuclear ambitions had been curtailed, or even that regime change might bring a less hostile government to power there. Analysts at JPMorgan, however, cautioned that past episodes of regime change in the region typically resulted in oil prices spiking by as much as 76% and averaging a 30% rise over time. Key will be access through the Strait of Hormuz, which is only about 33 km (21 miles) wide at its narrowest point and sees around 20% of the world's daily oil consumption. 'With the U.S. becoming involved, the risk of Iran retaliating by disrupting the flows of oil from the Middle East has risen significantly,' warned analysts at ANZ. 'Prices in the $90–95/bbl range would be the likely outcome.' For now, Brent was up a relatively restrained 1.9% at $78.46 a barrel, while U.S. crude rose 2% to $75.30. Elsewhere in commodity markets, gold edged up 0.2% to $3,375 an ounce. Share markets were proving resilient so far, with S&P 500 futures off 0.3% and Nasdaq futures down 0.5%, having both started with losses near 1%. Nikkei futures were just a fraction lower at 38,380, pointing to a small opening fall for the cash index. The dollar edged up 0.2% on the Japanese yen to 146.36 yen , while the euro dipped 0.3% to $1.1485. The dollar index firmed 0.25% to 99.008. There was also no sign of a rush to the traditional safety of Treasuries, with futures up only 1 tick. Futures for Federal Reserve interest rates were a tick lower, likely reflecting concerns a sustained rise in oil prices would add to inflationary pressures at a time when tariffs were just being felt in U.S. prices. Markets are still pricing a slim chance the Fed will cut at its next meeting on July 30, even after Fed Governor Christopher Waller broke ranks and argued for a July easing. Most other Fed members, including Chair Jerome Powell, have been more cautious on policy leading markets to wager a cut is far more likely in September. At least 15 Fed officials are speaking this week, and Powell faces two days of questions from lawmakers, which is certain to cover the potential impact of President Donald Trump's tariffs and the attack on Iran. The Middle East will be high on the agenda at a NATO leaders meeting at the Hague this week, where most members have agreed to commit to a sharp rise in defense spending. Among the economic data due are figures on U.S. core inflation and weekly jobless claims, along with early readings on June factory activity from across the globe.

Oil spikes as Trump's attack on Iran ramps up risks to supplies
(Bloomberg) — Oil surged after the US struck Iran's three main nuclear sites and threatened further attacks, exacerbating a crisis in the Middle East and stoking concerns that energy supplies from the region could be disrupted. Article content Global benchmark Brent rallied as much as 5.7% to $81.40 a barrel, before paring some of that gain in heavy trading. Timespreads widened. US President Donald Trump said air attacks had 'obliterated' the trio of targets, and threatened more military action if Iran didn't make peace. In its initial reply, Tehran warned the strikes would trigger 'everlasting consequences.' Article content Article content Article content Brent's prompt spread — the difference between its two nearest contracts, and a closely followed metric — widened to as much as $1.99 a barrel in backwardation, from $1.53 on Friday. That's a bullish pattern indicating concern about tight prompt supplies. Article content Article content The US assault — which targeted sites at Fordow, Natanz, and Isfahan — dramatically raises the stakes in the confrontation and increases the premium that traders are pricing into the global energy market. Still, the extent of the gains will depend on how Tehran opts to respond to the US moves. Article content The oil market has been gripped by the crisis since Israel attacked Iran more than a week ago, with futures pushing higher, options volumes spiking along with freight rates, and the futures curve shifting to reflect tensions about tighter near-term supplies. The Middle East accounts for about a third of global crude output, and a sustained increase in prices would boost inflationary pressures worldwide. Article content Article content 'The market will closely watch Iran's response — particularly whether it will move to disrupt Middle Eastern oil flows, directly or indirectly through its regional proxies,' said Muyu Xu, a senior crude analyst at Kpler Ltd. 'If Iran blocks the Strait of Hormuz, even for one day, oil can temporarily hit $120 or even $150.' Article content There are multiple, overlapping risks for physical crude flows. The biggest centers on the Strait of Hormuz, should Tehran seek to retaliate by attempting to close the chokepoint. About a fifth of the world's crude output passes through the waterway at the entrance to the Persian Gulf. Article content Iran's parliament has called for the closure of the strait, according to state-run TV. Such a move, however, could not proceed without the explicit approval of Supreme Leader Ayatollah Ali Khamenei.

Iranian Canadians and others watch and worry after U.S. strikes on nuclear sites
Iranian Canadians and Jewish groups turned worried eyes to the Middle East on Sunday, as U.S. strikes against three Iranian nuclear sites raised fears of escalating violence. Nimâ Machouf, a member of a Montreal Iranian women's association, said family members in Iran are living 'from one bomb to another.' 'I'm very worried because this will only accelerate the violence in the region,' she said in a phone interview. 'It will further aggravate the problem and take us further away from peace.' Machouf, who is also an epidemiologist and former NDP candidate, believes the strikes will only hurt the people who are fighting to free themselves from Iran's repressive regime. Attacks from other countries means that Iran's people 'are not protected by their government, nor protected by others, by the international community,' she said. 'So people feel abandoned by everyone, everywhere.'

Police in Toronto and Vancouver have published messages on social media platform X, confirming an increase in police presence in both cities while authorities monitor the situation in the Middle East. The Toronto police post said that more police presence 'can be expected wherever necessary,' while Vancouver police said more officers and resources will be deployed to 'certain places of worships, cultural and community centres, and diplomatic buildings.'

Story continues below advertisement 'We're listening to local faith leaders and community representatives from countries impacted by the conflicts … Our priority is your safety.' Prime Minister Mark Carney wrote on social media that U.S. military action was designed to alleviate the 'grave threat' Iran's nuclear program represents to international security. 'Canada has been consistently clear that Iran can never be allowed to develop a nuclear weapon,' he wrote. 1:42 Israel says world should 'thank' U.S. after strikes on Iranian nuclear sites But Carney said the situation in the Middle East was 'highly volatile,' and urged the parties to return to the negotiating table and reach a diplomatic solution. The interim president of the Centre for Israel and Jewish Affairs described Iran's nuclear program on Sunday as a 'grave danger to global peace and security.' 'Eliminating this threat is an essential step toward achieving a safer Middle East and a more secure and peaceful world,' wrote Noah Shack, who urged the federal government to 'stand strong against the Iranian threat.' Story continues below advertisement Kaveh Shahrooz, a lawyer and a senior fellow at the Macdonald-Laurier Institute, said many Iranians are worried about the impact the U.S. decision will have on civilians. 'I think there's quite a bit of (concern) simply because there's a lot of unknowns,' he said. Shahrooz said Iran's regime offers virtually no protection to its own citizens in the form of air raid sirens or shelters, and internet has been cut off. 'So there's a lot of fear about what we will find out once internet connection is restored and we're able to talk to our families again,' he said. Shahrooz said feelings among Canada's Iranian diaspora vary, from anger at the strikes to support for U.S. actions. 'Among the people who are not supportive of Iran's regime, I think there are some who are cheering and who are saying this was long overdue,' he said. 'And they're happy to see the Iranian regime's nuclear program effectively dismantled and to see that regime humiliated.' On the other hand, Machouf called any suggestion that Israel will 'liberate' Iran's people a 'masquerade' and said regime change must come from within. Gur Tsabar, a spokesperson with Jews Say No to Genocide, said a rally called 'Hands Off Iran' was organized for Sunday afternoon in Toronto to demand sanctions on Israel and a two-way arms embargo. He described recent Israeli and American actions in Iran as 'beyond disturbing.'
