Oil prices surged sharply and U.S. equities declined on Monday following fresh attacks in the Strait of Hormuz that struck vessels and a UAE oil facility, reigniting concerns about global energy supply. Brent crude climbed 5.8% to close at $114.44 per barrel, while West Texas Intermediate rose 4.4% to $106.42, according to Reuters. The violence, attributed to increased Iranian attacks on Gulf shipping, pushed energy risk to the forefront of market attention.
The S&P 500 slipped 0.41% to pull back from its recent record highs, with the Nasdaq Composite edging down 0.19%. The Dow Jones Industrial Average fell more sharply, losing 1.13%. Among the 11 S&P 500 sectors, only energy managed to gain, rising 0.85%, as investors rotated into oil-related stocks. The Cboe Volatility Index (VIX), Wall Street's fear gauge, jumped 7.65% to settle at 18.29, reflecting heightened anxiety.
UBS Flags Underappreciated Risks
UBS strategists, led by Artour Danilov, warned that global equities are not fully pricing in the economic fallout from the oil supply disruption. They likened the shock to the largest oil supply disruptions on record and cautioned that markets appear to be dismissing the second-round effects—the ripple damage to economic growth, corporate earnings, and central bank policy flexibility. In their base scenario, UBS expects global oil supply not to return to January levels until late 2026, with real oil prices remaining 30% to 40% above pre-disruption levels for roughly six months before gradually declining.
In a more adverse scenario where production only recovers halfway over a year, Europe would bear the brunt, with higher energy costs acting as a de facto tax on households and businesses. The timing is particularly concerning, as investors had been betting on solid earnings, subdued volatility, and continued AI investment heading into late April. The unexpected oil spike now reignites inflation fears, compresses corporate margins, and complicates central bank decisions, just as equities hover near their peaks.
Market Context and Sector Rotation
Ross Mayfield, investment strategist at Baird Private Wealth Management, commented that there is “not a lot of room for error,” underscoring the fragility of the current market environment. The VIX also saw a sharper intraday rise of 10% in early trading, according to MarketScreener, as traders cited fears of a potential Iranian response to U.S. efforts to steer vessels away from the Strait of Hormuz. Prior to the Feb. 28 U.S. and Israeli strikes on Iran, the strait accounted for roughly 20% of global oil and LNG traffic.
The energy sector’s outperformance comes as Morningstar highlighted that energy stocks have led the latest rally, driven by the Iran war stalemate and another jump in oil prices. However, the appetite for AI-linked “picks and shovels” remains robust, with companies like Microsoft (MSFT), Meta (META), Corning (GLW), Texas Instruments (TXN), and NextEra Energy (NEE) all benefiting from data-center demand.
OpenAI IPO Timeline Shifts, Competition Heats Up
In a separate development, OpenAI’s path to an initial public offering appears to have lengthened. Morningstar Canada, citing PitchBook analysis by Harrison Rolfes, reported that the probability of an OpenAI debut now looks more like mid-to-late 2027 than late 2026. Reasons include missed revenue targets, inflexible infrastructure costs, and rising pressure from competitors like Anthropic and Databricks. The Wall Street Journal reported that OpenAI has missed its latest user and revenue targets after ceding market share to Anthropic in both coding and enterprise segments.
Despite the pressures, OpenAI CEO Sam Altman and CFO Sarah Friar pushed back on talk of internal discord, insisting they are “totally aligned” on plans to ramp up compute purchasing. In a Bloomberg interview, Friar countered that OpenAI is hitting its targets and facing a “vertical wall of demand,” with compute capacity, not demand, usually being the bottleneck. Competition continues to intensify, as Anthropic is close to sealing a roughly $1.5 billion joint venture with Blackstone, Goldman Sachs, and other Wall Street players to sell AI products to private-equity-backed firms, according to the Wall Street Journal.
Outlook and Risks
If the Strait of Hormuz reopens sooner, or if OPEC+ brings more barrels online, or geopolitical tensions ease, crude could face a ceiling and energy stocks might lose momentum. Without those breaks, the risk morphs from market jitters into a longer-term drag on earnings, with pricier fuel, stubborn inflation, and tighter space for rate cuts. Investors are now closely watching for any signs of de-escalation or additional supply measures that could ease the pressure on global markets.
