San Francisco Frontiers - Oil rises, stocks mixed on US-Iran deadlock

Wall Street's three main indices moved in mixed directions as trading got underway, with the Dow edging higher while the broader S&P 500 and tech-heavy Nasdaq Composite both dipped.

In Europe, London rose while Paris and Frankfurt fell in afternoon trading after a mixed session in Asia, where Tokyo declined and Chinese indices advanced.

The stalemate between the United States and Iran dashed investors' hopes of an imminent peace deal and heightened concerns over further violence and disruptions to oil supplies through the Strait of Hormuz.

Trump described Tehran's response to the latest US outline for peace talks as "TOTALLY UNACCEPTABLE" in a social media post.

Iran said it had demanded the release of its frozen assets and the end of a US blockade of its ports.

Oil prices spiked more than four percent following the exchange, before easing to gains of under two percent as trading opened in New York.

"The price of oil remains highly reactive to news around the reopening of the Strait of Hormuz, both positive and negative," said Kathleen Brooks, research director at trading group XTB.

"Signs that tankers are getting through the Strait, even if it is a trickle, could weigh on the oil price in the coming days," she added.

But Briefing.com analyst Patrick O'Hare said Monday's gains were a "token response" compared to the 10 percent drop when the peace proposal was announced.

"There is a dose of concern, then, that the Iran situation could take a turn for the worse, but frankly there isn't any real fear that it will," he said.

O'Hare also noted that traders see Trump as unlikely to aggravate the oil supply situation ahead of his summit meeting with his Chinese counterpart Xi Jinping this week.

Beijing has said it is ready to work with Washington in pursuit of "more stability" as the two countries remain at odds over key issues including trade tariffs, the Middle East war and Taiwan.

In Asia, Tokyo stocks fell, Hong Kong was little changed and Shanghai jumped more than one percent, while Seoul climbed around four percent, supported by a rally in tech stocks.

A tech-led surge driven by strong quarterly earnings and optimism about artificial intelligence has pushed several markets to record highs despite the Mideast crisis.

In Tokyo, Nintendo shares plunged almost 10 percent after the Japanese gaming giant warned Friday of lower profits this year and said it would raise the price of its Switch 2 console.

UK government bond yields rose only slightly after Prime Minister Keir Starmer vowed to prove his "doubters" wrong in a speech seeking to quell a growing threat to his leadership following disastrous local election results.

"The relatively mild reaction in the bond market... suggests that traders do not believe that the threat to Keir Starmer will materialise," Brooks said.
