Lead Story#

Global energy markets are on edge after Iran abruptly reimposed the closure of the Strait of Hormuz, scuttling a fragile ceasefire and fueling fears of a massive supply disruption. The geopolitical whiplash has rattled policymakers, with global central bankers at the IMF meetings warning that a drawn-out conflict could trigger historic energy shortages and global stagflation.

Markets & Economics#

Despite mounting geopolitical fears, the S&P 500 surged to its first close above 7,100, booking a 9% gain for the month on hopes of a war resolution. However, the reality of $4-a-gallon gas and prolonged Middle East tensions has driven U.S. consumer sentiment down to a record low of 47.6, triggering a sharp pullback in discretionary spending at entertainment venues like Dave & Buster’s. To artificially suppress energy prices ahead of the midterms, the U.S. Treasury extended a sanctions waiver allowing countries to purchase Russian oil, a move that drew swift bipartisan criticism. The U.K. has also felt the economic sting, refusing to join U.S. military operations against Iran—a rift that prompted President Trump to single out London and threaten the U.K.’s 10% baseline import tariff ahead of a royal state visit.

Business & Earnings#

In the aviation sector, American Airlines shot down rumors of a potential merger with United Airlines, citing antitrust concerns over combining the world’s two largest carriers by capacity. Consolidation battles also hit the media landscape, with Nexstar announcing its appeal of a federal judge’s order halting its $3.54 billion acquisition of Tegna. Meanwhile, Nvidia is alienating its core gaming audience by reallocating limited memory supplies toward highly profitable AI systems like Blackwell and Vera Rubin, resulting in production cuts for GeForce GPUs. On the earnings front, India’s ICICI Bank reported a robust fourth-quarter standalone net profit of 137.02 billion rupees, beating analyst estimates on the back of strong retail loan growth.

Investing & Commentary#

While the broader market celebrates record highs, Berkshire Hathaway shares have uncharacteristically stalled, lagging the S&P 500 by 9.7 percentage points and falling 12% since Warren Buffett announced his upcoming retirement. For investors monitoring labor trends, young adults are increasingly treating graduate school as a career “insurance policy”, driven by fears that artificial intelligence is rapidly restructuring the workforce and eliminating entry-level jobs despite low headline unemployment.
