NATO is now considering a formal mission to protect shipping in the Strait of Hormuz, setting a clear political deadline for early July.
This development is a big deal for global energy markets and inflation. The Strait of Hormuz, a critical chokepoint for oil, has been effectively closed since late February 2026 due to regional conflict. This disruption has sent oil prices soaring by over 40%, embedding what analysts call a 'Hormuz premium' of roughly $34 per barrel into the price of Brent crude.
So, how did we get here? The causal chain is quite clear.
First, the crisis began in late February when Iran's actions throttled maritime traffic, creating an immediate and severe energy supply shock. This was the root cause of the market turmoil we're seeing today.
Second, in response, the International Energy Agency (IEA) authorized a record release of 400 million barrels from emergency stockpiles in March. While this was a significant move, it was only a temporary fix. Releasing stored oil can't replace the constant flow of tankers through a major waterway, so it only bought policymakers some time.
Third, as the closure dragged on, diplomatic efforts ramped up. Throughout March and April, countries led by the UK and France began assembling a multinational defensive coalition to escort ships. However, these efforts lacked the full weight of a formal military alliance, and the risk premium in oil prices remained stubbornly high.
This brings us to today. With diplomatic talks stalling and ad-hoc coalitions struggling to provide enough security to reassure markets and insurers, NATO's potential involvement marks a significant escalation. By signaling a July deadline, the alliance is trying to force a diplomatic resolution while preparing a more robust military alternative. This single move directly targets the security risk that has kept oil prices elevated for months.
