Suez and Panama are man-made canals that charge tolls for built infrastructure; Hormuz is a natural strait where UNCLOS permits only service fees, not passage tolls. There is no post-1945 precedent for a coastal state charging mandatory tolls on a natural strait. If Hormuz sets one, every chokepoint — Bab-el-Mandeb, Malacca, the South China Sea — becomes vulnerable. This post reads the precedent problem and why the service-fee distinction is the firewall.

The Strait of Hormuz has two shores. The southern bank is Oman’s Musandam Peninsula, and at 21 nautical miles wide with two 12-mile territorial seas, there is no neutral corridor — every transit passes through Iranian or Omani waters. Oman’s UNCLOS free-transit position is the single most important lever for converting the unilateral Iranian arrangement into an equal-access institutional one. This post reads the other shore and the Malacca-style cooperative model it points toward.
