Il Nuovo Postiglione - Oil prices jump, stocks drop as traders track Israel-Iran crisis

Investors' optimism the previous day that the conflict would not spread throughout the Middle East gave way to fears of further escalation as the conflict entered its fifth day.

"Middle East tensions are showing no signs of easing back, putting investors on high alert," said Russ Mould, investment director at AJ Bell.

Trump said he was aiming for a "real end" to the conflict, not just a ceasefire after he departed the G7 summit in Canada.

Trump may decide that "further action" is needed to stop Iran's nuclear programme, Vice President JD Vance said later Tuesday, responding to speculation that the United States could intervene in the conflict.

Wall Street's main indices were all lower in late morning trading, with a larger-than-expected 0.9 percent drop in May US retail sales also dampening sentiment.

Worries about tariffs hurting consumer spending and uncertainty over Iran "has buyers holding back their own firepower at the moment", said Briefing.com analyst Patrick O'Hare said.

European equities ended the day lower, while Asia turned in a mixed performance: Hong Kong fell, while Shanghai was flat and Tokyo advanced.

Despite mounting calls to de-escalate, neither side has backed off from the missile blitz that began Friday, when Israel targeted Iranian nuclear and military facilities.

Oil prices climbed 2.9 percent on Tuesday after swinging between gains and losses since Friday's initial surge.

But gains were tempered after the International Energy Agency said in its 2025 report that global demand would fall slightly in 2030 for the first time since the start of the Covid pandemic in 2020.

"We don't expect high oil prices to be with us for a very long time," said IEA executive director Fatih Birol.

He added that the IEA is "monitoring the situation" and is "ready to act" in the case of a supply disruption.

"There are a lot of eyes on the oil markets -- not just for geopolitical reasons but for their broader economic impact," said Matt Britzman, senior equity analyst at Hargreaves Lansdown.

"Energy prices remain a crucial piece of the inflation puzzle, and falling oil had been a cornerstone of the US President’s pressure campaign to nudge the Fed toward rate cuts," he added.

Investors are looking ahead to the US Federal Reserve's decision on Wednesday, with policymakers expected to hold interest rates.

Dealers also kept tabs on the G7 summit, where world leaders pushed back against Trump's trade war, arguing it posed a risk to global economic stability.

Britain, Canada, Italy, Japan, Germany and France called on Trump to reverse course on his plans to impose even steeper tariffs on countries across the globe next month.

"Trump leaving the summit early means the prospects of any more deals look slim in the days ahead," said City Index and FOREX.com analyst Fawad Razaqzada.

Trump managed to sign documents with UK Prime Minister Keir Starmer to confirm an agreement over trade with Britain.

On currency markets, the yen briefly edged up against the dollar after the Bank of Japan stood pat on interest rates and said it would slow the tapering of its bond purchases, but later gave up its gains.
