Strait of Hormuz reopens with expected improvement for fuel supply
The reopening of the Strait of Hormuz, announced on Friday, April 17, 2026 by the Iran Ministry of Foreign Affairs, brought immediate relief to stock exchanges and global aviation markets. However, the recovery for air transport is proving far from instantaneous.
Oil prices reacted quickly to the news. On Friday afternoon, crude prices dropped by around 10% to roughly US$90 a barrel. After weeks of volatility, if stability holds, this will give airlines a much-needed financial breather.
Lower fuel costs typically translate into improved margins and, eventually, more stable fares. For an industry heavily exposed to jet fuel price swings, the reopening is a clear positive signal.
However, the operational reality is more complex. Asian and European aviation in particular remain vulnerable, as a significant share of jet fuel supply is sourced from the Gulf. During the disruption, supply chains were stretched, inventories depleted, and airlines were forced to cut capacity, delay flights, or in some cases cancel services altogether.
These effects do not disappear overnight. Even with maritime traffic resuming through Hormuz, it will take time for tankers to reach refineries, for fuel to be processed, and for stocks to be replenished at major airport hubs. Industry observers suggest the supply chain could take several weeks, if not months, to fully normalize.
In the meantime, airlines are expected to continue operating cautiously. Capacity is likely to remain constrained on some long-haul routes, while carriers prioritize high-demand and higher-yield services. Fuel surcharges introduced during the crisis may also linger in the short term despite easing oil prices.
There is some good news for passengers. Following Iran’s acceptance of a ceasefire and the reopening of Hormuz, major Gulf carriers feel more confident to gradually restore capacity as flights resume.
The reopening reduces the risk of widespread disruption during the peak summer season and should help stabilize fares over time. In the near term, however, travelers may still face higher ticket prices—though not as elevated as in late March—alongside limited availability on some routes. A gradual return to normality is now underway.
