Hormuz crisis is redrawing the map of global energy security |
For decades, the Strait of Hormuz has been described as the world’s most dangerous energy chokepoint. Stretching just 39 kilometers at its narrowest point and bordered by Iran to the north and Oman and the United Arab Emirates to the south, this narrow waterway has long carried an outsized strategic significance. Nearly one-fifth of the world’s oil supply and a substantial share of global liquefied natural gas (LNG) passes through this corridor every day. Yet the events of early 2026 demonstrated something even more consequential: the Strait of Hormuz is not merely a vulnerable passageway but a single point of failure capable of reshaping the entire global energy system.
The recent crisis surrounding the strait did more than disrupt shipping. It revealed how modern energy security can be upended not only by direct military blockades but also by financial and psychological pressure on global markets. In doing so, it has triggered a structural rethinking of how energy is transported, traded and secured across the world.
The turning point came when tensions between Iran, the United States and Israel escalated dramatically following strikes on Iranian nuclear facilities and the assassination of Iran’s Supreme Leader, Ayatollah Ali Khamenei. In response, Iran’s Islamic Revolutionary Guard Corps issued a warning that no vessels would be permitted to pass through the Strait of Hormuz. Although Iran did not deploy a massive naval blockade, a series of drone attacks on tankers near the waterway proved sufficient to trigger a cascading crisis.
Within days, tanker traffic through the strait collapsed by nearly 90 percent. Oil markets reacted immediately, pushing prices sharply upward, while thousands of vessels were left stranded across the region. Yet the most striking aspect of the disruption was that the strait did not need to be physically sealed. The real closure occurred in the insurance market.
War-risk premiums for ships transiting the strait had already been rising amid mounting tensions. Before the attacks, insurance rates had increased from around 0.125 percent of ship value to between 0.2 and 0.4 percent, adding roughly $250,000 to the cost of a single supertanker voyage. After the drone strikes, however, insurers withdrew protection and indemnity coverage entirely, making the route commercially unviable for many shipping companies.
