Heraldo de Madrid - Oil surges, stocks fall on Middle East fears as Israel strikes Iran

Investors ran for the hills on news of the attacks and a warning that retaliatory action from Tehran was possible, after US President Donald Trump said a "massive conflict" in the region was possible.

While Tel Aviv said it had struck military and nuclear targets Iran said residential buildings had been hit.

Israeli Prime Minister Benjamin Netanyahu said in a video statement: "This operation will continue for as many days as it takes to remove this threat.

"We struck at the heart of Iran's nuclear enrichment programme. We targeted Iran's main enrichment facility at Natanz. We also struck at the heart of Iran's ballistic missile programme," he added.

Iranian nuclear scientists "working on the Iranian bomb" had also been hit, he said.

Israeli Defence Minister Israel Katz cautioned that "a missile and drone attack against the State of Israel and its civilian population is expected in the immediate future".

Trump had previously warned that an attack could be on the cards, telling reporters at the White House: "I don't want to say imminent, but it looks like it's something that could very well happen."

The US leader said he believed a "pretty good" deal on Iran's nuclear programme was "fairly close", but that an Israeli strike on the country could wreck the chances of an agreement.

A US official said there had been no US involvement in the operation.

Still there are worries the United States could be sucked into the crisis after Iran threatened this week to target US military bases in the region if a regional conflict broke out.

Both main oil contracts, which had rallied earlier in the week on rising tensions, spiked more than eight percent amid fears about supplies of the commodity.

The rush from risk assets to safe havens saw equity markets across Asia tumble and bonds rally with gold. US and European equity futures were deep in the red.

"The Middle East powder keg just blew the lid off global markets," said Stephen Innes at SPI Asset Management.

"Equity futures are plummeting. Bond yields are sinking. Gold and oil are skyrocketing," he added.

"Brent crude futures are racing toward the mid-$70s range -- but if the Strait of Hormuz, which accounts for 20 percent of global oil flows, finds itself in the blast radius, you can add another $15 to the bid.

"If Iran holds back, we get a relief bounce. But if missiles start raining down on Tel Aviv or Tehran retaliates with real teeth, we're staring down a scenario that could redefine the macro narrative for the rest of 2025."

Banking giant JPMorgan Chase had warned just this week that prices could top $130 if the worst-case scenario developed.

Market sentiment had already been low after Trump sounded his trade war klaxon again by saying he would be sending letters within the next two weeks to other countries' governments to announce unilateral levies on their exports to the United States.

The "take it or leave it" deal spurred fears he would reimpose the eye-watering tolls announced on April 2 that tanked markets before he announced a 90-day pause.
