Hello, this is Hui Jie writing to you from Singapore. Welcome to another edition of CNBC's Daily Open.
Tim Cook appeared emotional as he led his final Worldwide Developers Conference as Apple CEO. The tech giant, in a move signaling its embrace of the current industry trend, unveiled an 'AI' label for its long-standing virtual assistant, Siri. Meanwhile, geopolitical tensions continue to cast a shadow over global markets, with Israeli Prime Minister Benjamin Netanyahu stating that the conflict with Iran and its proxies "has not yet ended."
What You Need to Know Today
In a poignant moment, Tim Cook delivered his farewell remarks at his last WWDC as Apple CEO. The company also announced a significant rebranding of its virtual assistant and chatbot, now known as Siri AI, promising a "profoundly more capable assistant." Apple further addressed criticisms of its Liquid Glass interface by introducing enhanced customization options, allowing users to fine-tune settings such as transparency, text labels, and toolbars.
The technology sector is buzzing with IPO activity. OpenAI has confidentially filed for an IPO with the Securities and Exchange Commission, following a similar move by rival Anthropic last week. This surge in tech listings is further bolstered by the anticipated public debut of Elon Musk's SpaceX.
OpenAI, currently valued at over $850 billion, has reportedly been preparing for its public offering as early as the fourth quarter of this year. This wave of tech optimism has contributed to gains in the S&P 500 and Nasdaq Composite.
Despite the tech sector's buoyancy, geopolitical tensions continue to introduce uncertainty. Iran informed CNBC that it had ceased strikes against Israel but warned of resuming hostilities if Israeli forces continued to attack Lebanon. In response, Israeli Prime Minister Benjamin Netanyahu declared that the war against Iran and its proxy Hezbollah "has not yet ended."
These developments have influenced oil prices, with Brent crude rising 1.25% to $94.25 a barrel and U.S. West Texas Intermediate futures seeing a marginal increase in early Tuesday trade. Analysts point to China's reduced crude imports, falling from 11.7 million barrels per day in February to just under 9 million by late May, as a key factor keeping oil prices below $100 by easing demand and mitigating supply shocks from the Strait of Hormuz.
In Asia, U.S. scrutiny of Chinese companies is intensifying. Washington has expanded its list of firms believed to be aiding Beijing's military, adding tech giant Alibaba, automaker BYD, and internet search provider Baidu. Companies on this list will face restrictions on U.S. military contracts starting in 2027.
And Finally...
The International Air Transport Association (IATA) has issued a stark warning: global airline profits are projected to halve this year, primarily due to a staggering $100 billion increase in jet fuel costs. IATA's outgoing director general, Willie Walsh, cited the U.S.-Iran conflict, which began on February 28th, as a significant factor in the surge of oil and jet fuel prices, expecting them to be 70% higher year-on-year. This, combined with lingering pandemic and geopolitical challenges, places considerable strain on the airline industry.
