Geopolitical tensions in the Gulf returned to the foreground on Wednesday, prompting a market reaction that was most visible in energy and fixed income even as equity investors largely focused on the technology-driven rally.
U.S. forces intercepted Iranian missile attacks in the Gulf and launched strikes in response, a sequence of events that lifted Brent crude by more than 2 percent to around $98 per barrel. The rise in crude coincided with a move higher in bond yields, reflecting investors' reappraisal of risk and inflation upside in the near term.
Yet stock markets showed few signs of broad panic. The chip-heavy SOX index jumped more than 5 percent on Tuesday, and the wider S&P 500 notched another record closing high, extending its winning streak to nine straight sessions. Deutsche Bank has noted that a 10th consecutive gain for the S&P 500, if it materializes, would be the longest such run in over three decades.
That divergence - stronger oil and bond moves on one hand, calm and record-setting equity behavior on the other - shaped market narratives through the Asian session, where technology-focused indexes followed Wall Street's lead to new highs driven by investor enthusiasm for artificial intelligence.
U.S. equity futures were modestly lower ahead of the opening bell and European stocks slipped in early trading, suggesting that risk appetites may be tempering after the Asian advance.
Currency markets reflected the geopolitical flare-up as well. The yen again tested the psychologically important 160 per dollar mark, pressured by a stronger U.S. dollar in the wake of the Gulf exchanges. Japanese authorities have intervened in the currency market in recent weeks, spending roughly $73 billion on yen-buying operations to stem the currency's decline after it moved past that level.
The corporate calendar and technology developments added to the backdrop. Broadcom is due to report quarterly results after the market close and remains a central player in the AI infrastructure buildout, now valued at about $2 trillion. Marvell Technology also enjoyed a sharp gain, rising 25 percent on Tuesday to a record high after a public endorsement from Nvidia's chief executive, who described Marvell as the next "trillion-dollar company".
IPO speculation persisted in the market, with details emerging that SpaceX intends to set an initial public offering price at $135 per share, a level that would raise as much as $75 billion if the plan holds. The size and pricing of the proposed deal have been prominent items of investor attention.
On the innovation front, Microsoft announced what it described as a significant advance in quantum computing: an AI-redesigned quantum chip that the company says could make commercially viable quantum machines possible within three years. The announcement added to the sense of transformational technological change underpinning investor optimism in AI-related equities.
Macro data this week kept policy debates alive. Tuesday opened a heavy week for U.S. labor market indicators with a larger-than-expected rise in April job openings, a reading that calls into question views that the labor market is softening and that will keep hawkish Federal Reserve voices attentive. Investors await ADP's private payrolls report for May due later in the day, before the headline May employment report on Friday. Additional scheduled releases include the ISM services PMI and the Fed's Beige Book, and speeches from Federal Reserve officials Michael Barr and Lorie Logan.
Market participants will be watching whether incoming data reinforce the view of resilient labor demand and what that implies for interest rate expectations. For now, markets exhibit a split personality: elevated energy prices and rising yields alongside frothy equity valuations concentrated in a narrow set of technology and AI-exposed names.
Chart of the day
Since 2025, shares of certain chip designers, including Broadcom and Marvell, have appreciated sharply as demand for custom AI chips from hyperscale cloud customers has grown and those customers seek to diversify away from exclusive reliance on a single supplier's processors. Broadcom's upcoming quarterly report will be closely watched for signs of demand and margin trends tied to that dynamic.
Events to watch today
- U.S. ADP private payrolls for May (8:15 a.m. EDT)
- ISM May services PMI (10:00 a.m. EDT)
- Release of the Federal Reserve's Beige Book
- Speeches by Fed officials Michael Barr and Lorie Logan
Investors and policymakers will parse these data points for signals on labor market momentum and the interest rate outlook amid ongoing geopolitical uncertainty and concentrated equity market leadership.
