US markets tumble as oil surge reignites inflation fears
Brent crude hits $100-$120 range after Strait of Hormuz closure sparks largest supply shock in history
US stocks extended losses on Tuesday as oil prices surged to their highest levels in two years, reigniting inflation concerns and threatening to derail the economic recovery. Brent crude climbed into the $100-$120 per barrel range following a disruption to the Strait of Hormuz, a critical maritime chokepoint that handles approximately 20% of global oil transit, amid escalating tensions between the US and Iran.
The supply disruption represents the largest supply shock in the history of the global crude market, according to Goldman Sachs analysts. The bank raised its 2026 Brent crude forecast to $85 per barrel from a previous estimate of $77, with prices expected to average $110 during March and April as the disruption persists. West Texas Intermediate forecasts were similarly increased to $79 from $72.
Shaikh Nawaf Al-Sabah, CEO of Kuwait Petroleum Corporation, warned that the closure would be "beyond catastrophic" and would "trigger domino effect across global economy." Goldman Sachs' analysis assumes oil flows through the Strait will operate at roughly 5% of normal capacity for six weeks, followed by an additional month for recovery operations.
The sudden spike in energy costs has sent shockwaves through financial markets, with investors repricing risk across multiple asset classes. The S&P 500 and Dow Jones Industrial Average both fell more than 2% in morning trading, while energy stocks rallied on the price surge. Transportation, industrial, and consumer discretionary sectors led the decline as higher fuel costs threaten corporate margins and consumer spending power.
Inflation expectations, which had been moderating in recent months, have spiked sharply. The surge in oil prices raises the prospect of the Federal Reserve maintaining higher interest rates for longer, as central bankers grapple with the second major energy price shock in less than four years. Treasury yields rose, with the 10-year note climbing above 4.5% for the first time since late 2025.
Analysts warn that the duration of the disruption will determine the economic impact. If the Strait remains closed beyond Goldman Sachs' six-week projection, Brent prices could average $95-100 through much of the second quarter, potentially pushing global GDP growth down by 0.5-1.0 percentage points. Strategic petroleum reserves in the US and other consuming nations are being deployed to mitigate immediate supply shortages.
The situation underscores the ongoing vulnerability of global energy markets to geopolitical tensions, despite efforts to diversify supply chains and expand alternative energy sources. The Strait of Hormuz, a narrow waterway between Iran and Oman, has been a flashpoint for decades, but the current conflict marks the most severe disruption since the 1980s Tanker War.
