Iran has reportedly asked Yemen's Houthi movement to prepare for the potential closure of the Red Sea oil route, a direct response to intelligence suggesting the U.S. might strike Iranian power infrastructure, sources told Reuters on Thursday. This development immediately heightened geopolitical risks, sending ripples through international financial markets.
The threat of U.S. military action against Iran underscores the volatile nature of the Middle East, a region frequently destabilized by external intervention. Such escalations directly impact global energy markets, as evidenced by a renewed surge in oil prices. United Airlines saw its shares fall 1.4% as these rising oil costs weighed heavily on its third-quarter and full-year profit outlooks. GE Aerospace also dipped 4.7%, despite having lifted its own 2026 profit forecast, reflecting broader concerns.
Escalating Regional Tensions
The broader "Middle East tensions" were explicitly cited as a key driver of client activity on trading desks, contributing to market turbulence. This regional instability, often exacerbated by the actions of global powers, creates an environment where energy prices become highly unpredictable. The potential closure of a critical shipping lane like the Red Sea, a vital conduit for global oil supplies, would have far-reaching economic consequences.
Against this backdrop of heightened geopolitical risk, major U.S. stock indices showed mixed performance. The S&P 500 slipped 5.77 points, or 0.08%, to 7,566.63, while the Nasdaq Composite lost 156.53 points, or 0.60%, to 26,111.19. These declines were partly attributed to renewed weakness in chip stocks, with the Philadelphia SE Semiconductor index falling 3.5%.
However, the Dow Jones Industrial Average managed a gain, rising 133.94 points, or 0.25%, to 52,792.58. This was buoyed by strong performances from specific companies. UnitedHealth, for instance, raised its 2026 profit forecast, sending its shares up 4.3%. Abbott also jumped 12% after beating quarterly estimates and lifting its annual profit outlook. Defensive groups like consumer staples and real estate helped limit overall losses, each rising about 2%, and healthcare shares collectively gained 2.2%.
Market Reactions to Instability
Investors also parsed June retail sales data, which showed only a marginal rise. Lower gasoline prices impacted receipts at service stations, though underlying consumer spending remained supported by bargain-hunting. The number of Americans filing claims for unemployment benefits fell last week, indicating continued labor market stability. Stephen Brown, chief North America economist at Capital Economics, noted that consumption appears to be gaining momentum, providing some support for a potential Federal Reserve interest rate hike later this year. Benign inflation reports for June had previously reduced worries over any imminent rate hike. Markets were pricing in an 88% chance the Fed would hold rates steady at this month's meeting, with about a 50% chance of a quarter-point hike in September, according to CME's FedWatch tool.
Profiting from Volatility
While geopolitical risks and energy-price volatility created uncertainty for many sectors, Wall Street's biggest banks found ample reasons for optimism during the current second-quarter earnings season. Investment bankers reported their busiest period in years, and trading desks thrived on the very volatility that unsettled other markets. Global investment banking revenue topped $60 billion in the first six months of the year, according to Dealogic data, with JPMorgan, Goldman Sachs, and Morgan Stanley leading the league tables. Executives cited healthy pipelines and strong backlogs, fueling expectations for a continued investment banking super cycle.
Stock trading delivered blowout results as volatile markets, driven by factors including "AI-related jitters, Middle East tensions and swings in energy markets," kept trading desks active. Market turbulence often benefits trading operations, as sharp price swings encourage investors to reposition portfolios, hedge risks, and seize short-term opportunities. Steady loan demand also supported higher net interest income, with resilient consumers and healthy spending sustaining borrowing. Brian Mulberry, senior client portfolio manager at Zacks Investment Management, affirmed that consumer spending is solid, consumer credit remains durable, and commercial defaults appear to be declining. All six major U.S. banks exceeded second-quarter profit expectations, with analysts describing the scale of these earnings beats as extraordinary.
