Hormuz Strait closure through September threatens global oil supply chains and could push prices higher
Executive summary: Professor Nicolazzi of Torino University and Isab board chairman warned in an interview that keeping the Strait of Hormuz closed until September would create serious problems for fuel transport, despite ample oil and gas supplies. The Hormuz corridor carries about a fifth of global oil shipments; a prolonged shutdown would disrupt supplies to refineries, raise freight costs and potentially lift benchmark crude prices.
Who is involved: Key actors include the expert Nicolazzi, Isab (Italian refining group), oil traders, shipping companies, and governments monitoring Gulf security.
Likely next: If the closure persists, market participants may anticipate releases from strategic reserves and increased freight premiums, while diplomatic efforts continue to reopen the waterway.
Professor Nicolazzi of Torino University and Isab board chairman warned in an interview that keeping the Strait of Hormuz closed until September would create serious problems for fuel transport, despite ample oil and gas supplies. He noted that the paradox of abundant crude becomes meaningless if it cannot be moved, highlighting the vulnerability of global energy logistics to Gulf security disruptions. The warning underscores potential upstream and downstream impacts on refiners, shippers and consumers if the waterway remains blocked.

Analysis — what this means
Likely next events
- If Hormuz remains closed through 30 September 2026, Brent crude futures could rise above $90 per barrel, based on prior 3‑5% price jumps during similar threats.
- Isab may activate contingency freight contracts and consider alternative routing via the Cape of Good Hope, increasing voyage length by ~14 days.
Sectors affected
- Oil and gas shipping
- Refining
- Aviation jet fuel
- Petrochemicals
Regulatory implications
- EU’s Oil Stockpiling Directive (2009/119/EC) could trigger mandatory releases of strategic reserves if the Hormuz disruption exceeds 30 days.
- US Department of Energy may authorize drawdowns from the Strategic Petroleum Reserve under the Energy Policy and Conservation Act if sustained supply shortages are declared.
Historical parallels
- In May 2019, tanker attacks in the Strait of Hormuz preceded a ~3% rise in Brent crude prices.
- The March 2021 Suez Canal blockage caused a temporary ~4% increase in global oil freight rates.
