THE NEW GEOPOLITICAL RISK PREMIUM

When Iran closed the Strait of Hormuz in February, many expected the global oil market to enter another prolonged period of turmoil. Nearly one-fifth of the world's seaborne oil trade passes through this narrow waterway, making it one of the most strategically important energy chokepoints on the planet. Oil prices rose as the conflict escalated, yet the market reaction proved far more measured than many analysts had anticipated. Following the ceasefire, investors quickly shifted towards pricing in de-escalation rather than prolonged disruption. Markets assumed that, despite the military confrontation, the principal actors would ultimately avoid disrupting one of the world's most important energy corridors.

Over the past decade, global energy markets have become significantly more resilient. The US shale revolution, larger strategic petroleum reserves and increasingly diversified supply chains have all reduced the immediate impact of supply disruptions. More importantly, the economic interests of the region's key players imposed natural limits on escalation. Iran continues to depend heavily on oil export revenues, with China remaining its largest customer, while Gulf producers such as Saudi Arabia and Qatar rely on uninterrupted maritime trade to finance their long-term economic transformation programmes. Rather than pricing the worst-case scenario, markets initially priced in the rational behaviour of the principal actors.

The renewed escalation involving the Iran-backed Houthis fundamentally changed the market's perception of risk. By threatening commercial shipping through the Bab el-Mandeb Strait, the conflict expanded beyond Hormuz and introduced a second strategic maritime chokepoint into the equation. Investors suddenly had to reassess the risk that disruptions could spread across multiple interconnected routes linking the Middle East to global energy markets.

Markets responded accordingly. As traders rebuilt the geopolitical risk premium, Brent crude climbed to an intraday high of $95.47 per barrel before surging above $100 following the escalation in the Red Sea.

More important than the price increase itself was what it revealed about the market's changing assessment of geopolitical risk. The initial response to the Hormuz crisis reflected confidence that economic rationality would ultimately outweigh military escalation. The Houthi attacks overturned that assumption by introducing a second strategic variable into the market's risk calculation.

WHY THIS MATTERS

The latest increase in oil prices was driven not simply by renewed fighting, but by a reassessment of geopolitical risk. Following the Hormuz ceasefire, markets believed the conflict had become more predictable. The Houthi attacks changed that calculation by introducing a second threatened maritime chokepoint, forcing investors to rebuild the geopolitical risk premium. Today's energy markets are increasingly pricing not isolated geopolitical events, but the interaction of multiple strategic risks across the global energy system.
