The China Mail - Asia stocks mixed over hopes of US-Iran deal, tech gains

Negotiations between Washington and Tehran to end the Middle East war have kept investors guessing with reports a deal was close undermined by fresh US strikes on Iran on Monday.

Tehran accused Washington of breaching their ceasefire, in place since April 8, and warned that it was ready to retaliate against US targets across the Gulf.

The strikes pushed up the price of Brent North Sea crude, the international benchmark, by almost 4.5 percent on Tuesday, reaching back above $100 a barrel.

But Brent and US West Texas Intermediate futures contracts were down around one percent Wednesday morning on renewed hopes a deal to reopen the blockaded Strait of Hormuz was on track.

"There remains an air of cautious optimism in markets that an MoU between the US and Iran will be signed and detailed throughout the week, although the central expectation and broad positive sentiment has been dented by the recent US defence strikes and Iran stating these measures breach the agreement," said Chris Weston, Head of Research at Pepperstone.

Asian stocks were mixed on Wednesday, with Seoul leading the climbers, jumping around five percent, mostly driven by chipmaker stocks.

Shares of South Korean chip giant SK hynix, which furnishes Nvidia with high-bandwidth memory, climbed more than 10 percent on Wednesday to reach $1 trillion in market capitalisation.

Its main rival, Samsung Electronics, also posted strong gains helped by its union approving a deal with management that secured huge annual bonuses and averted a major strike.

Tokyo rose around 1.3 percent, with Taipei, Sydney, Wellington and Bangkok also up.

Hong Kong was flat, while Shanghai, Kuala Lumpur, Jakarta, Singapore and Manila were down.

It comes after Wall Street stocks mostly rose, lifting the S&P 500 and Nasdaq to fresh records, with chip company Micron piling on nearly 20 percent to also hit a $1 trillion market capitalisation.

"In practical terms, the market heard one thing loud and clear. AI demand is no longer just about chips powering large language models. It is now about the memory systems required to feed those models at industrial scale," said SPI Asset Management analyst Stephen Innes.

The Middle East war, which began in late February, has disrupted the Hormuz strait, a vital oil and gas trading corridor, driving up energy prices and stoking global inflation.

"The latest rally across global equities feels less like a vote of confidence in permanent peace and more like traders front-running the possibility that Washington and Tehran eventually find a way to step back from the ledge," Innes said.
