Asian equities faced a challenging start to the trading week as major AI leaders called for a more cautious approach to frontier model development, while a spike in oil prices reignited concerns about inflation pressures. The combination of these factors weighed heavily on investor sentiment, with technology shares bearing the brunt of the selloff.

South Korea's KOSPI index tumbled more than 3%, with SK hynix dropping over 5% and Samsung Electronics falling more than 3%. The chipmakers, often described as the "picks and shovels" of the AI boom, led the decline alongside Japanese semiconductor stocks. Japan's Nikkei 225 opened 0.6% lower before extending losses to 2%, with SoftBank shares plunging 11%.

Meanwhile, Brent crude surged over 3% to $107.99 per barrel after Saudi Arabia shut a critical oil pipeline and Oman postponed a scheduled meeting with Iran and other nations. The energy market disruption intensified concerns about the inflation outlook, compounding the pressure on global markets. Nasdaq 100 futures fell more than 1%, while S&P 500 futures declined 0.6%.

Where the pressure originates

On Saturday, Anthropic CEO Dario Amodei announced the company would introduce additional safety measures, including independent third-party assessments, and urged the industry to voluntarily slow the pace of frontier model development. OpenAI CEO Sam Altman quickly voiced his support, and xAI's Elon Musk also weighed in, saying "Dario is right."

The rare alignment among three leading AI institutions cast doubt on the sector that has driven this year's equity rally. Nick Twidale, chief market analyst at AT Global Markets in Sydney, noted that the week could open with significant turbulence as investors assess the valuation implications of the strategic shift by top AI companies. He expects major Asian tech firms supplying these large AI companies to feel the impact first.

However, some market participants believe the selloff may be more emotional than fundamental. Kerry Craig, global market strategist at J.P. Morgan Asset Management, suggested that until the development slowdown translates into actual cuts in capital expenditure guidance or delays in model releases, it is likely sentiment-driven rather than valuation or earnings-driven.

On the corporate front, sources indicate Anthropic has selected Nasdaq as the venue for its potential record-breaking IPO. Meanwhile, Sam Altman stated that OpenAI will not pursue an IPO this year, citing the company's focus on addressing AI safety-related issues.

Oil price surge stokes inflation worries and rate hike bets

The energy market's sudden shift added further strain to an already fragile market environment. After Saudi Arabia shut a key oil pipeline following a drone attack and a scheduled meeting between Iran and Gulf states was postponed, Brent crude climbed 2.8% to $107.55 per barrel, while U.S. West Texas Intermediate rose 2.5% to $102.51, pushing oil back above the $100 mark.

The oil price rally coincided with U.S. inflation data released last Friday. According to the Bureau of Labor Statistics, core CPI, excluding food and energy, rose 0.3% month-over-month and 2.4% year-over-year in August. Headline CPI increased 0.4% monthly and 3.4% annually, both exceeding expectations.

The inflation figures drove Treasury yields higher, with the two-year yield climbing 4 basis points on Friday and the 10-year yield approaching the critical 5% level, currently trading at 4.95%. Swap market pricing now indicates a greater than 90% probability of a Federal Reserve rate hike this Wednesday.

Martin Whetton, head of financial markets strategy at Westpac Banking Corp, noted that expectations for a September FOMC rate hike are already well-established, with pricing probabilities at 90%. Following Friday's CPI data, Treasury yields moved broadly higher, and Asian fixed income markets will continue to be influenced by this dynamic today.

Analysts point out that oil prices returning above $100, combined with escalating tensions in the Middle East, make it increasingly difficult to ease global inflation pressures. The breathing room policymakers had hoped for is rapidly shrinking, suggesting borrowing costs will likely remain elevated for an extended period.
