On Monday, Asian stock markets slumped while oil prices hit five-month highs as investors watched closely to see if Iran would retaliate following US strikes on its nuclear facilities. The US dollar edged up slightly, signaling a mild flight to safety, while global equities remained pressured. The central worry? The possibility of Iran disrupting the crucial Strait of Hormuz—through which roughly 20% of global oil and gas flow—in retaliation.

The Strait of Hormuz: A Strategic Flashpoint

The Strait of Hormuz—a 33 km-wide but critically narrow maritime passage—connects the Gulf to the open ocean. An estimated 20 million barrels of oil and a fifth of worldwide LNG flow through it daily. The Iranian parliament even voted to approve a closure in response to the US actions, though such a move remains contingent on approval from the Supreme National Security Council. Experts caution this could serve as both a bargaining chip and a threat to global energy markets.

Oil Prices React Sharply

Brent crude surged nearly 3%, rising to around $78.85 per barrel—levels not seen since January. West Texas Intermediate also ticked upward to approximately $77.20. Goldman Sachs reported the inclusion of a $12-per-barrel geopolitical risk premium, and warned prices could exceed $90—and possibly reach $110—if Iran hits shipping lanes.

Broader Market Implications

Beyond energy, global equities in the US and Europe showed signs of vulnerability. Indian markets opened sharply lower, with the Sensex tumbling over 800 points as geopolitical uncertainty threatened inflation outlooks and disrupted supply chains. Economic models suggest such instability could shave 0.8% off global GDP if left unchecked.

The Risk of a Strait Shutdown

While Iran has historically threatened to close the Strait, analysts believe an actual shutdown is unlikely. The move risks punishing Iran’s own economy—its exports rely heavily on this route—as well as alienating major partners like China. Yet Iran retains several asymmetric capabilities—mining, anti-ship missiles, small boat swarms, submarine-deployed mines—that could disrupt traffic short of full closure. EIA data confirms there’s no viable shipping alternative, so even minor disruptions would ripple far beyond the region .

Investors Seek Sanctuary

Markets responded with increased demand for safe-haven assets. The dollar strengthened, and gold prices climbed as investors sought refuge from the risk of escalating conflict . Meanwhile, US federal fiscal data became secondary to geopolitical price risks, especially for inflation-sensitive central bank decisions .

What Lies Ahead

Key factors to monitor include:
1. Iran’s response. Will the Strait remain untouched, or will Iran escalate—perhaps through harassment of vessels, mines, or missile fire?
2. Market sensitivity. Oil could top $100 if real threats emerge, pushing global inflation upward.
3. Economic ripple effects. Slower growth, higher borrowing costs, and weakened emerging markets loom if tensions persist.

Bottom Line

While temperatures have cooled from Monday’s peak tension, the situation remains fragile. A single misstep—in Tehran or Washington—could significantly tighten oil markets and spook investors worldwide. For now, investors are caught in a geopolitical vise: evaluating whether Iran’s rhetoric is empty or a prelude to economic turmoil.

Stay alert—and buckle up: global markets are navigating a narrow and dangerous passage, much like the ships through the Strait of Hormuz.
