Somayeh Rafiei, a member of parliament from Tehran, said countries using the strait for shipping, energy transit and food supplies could be required to pay charges to Iran if it provides security.
“We are pursuing a plan under which countries using the Strait of Hormuz… would be obliged to pay tolls and taxes to the Islamic Republic of Iran,” she said.
She added that Iran provides regional security and that countries “must pay a security tax” in return.
The proposal comes as shipping through the strait has dropped sharply and in some cases halted following attacks on vessels and threats from Iran, disrupting a route that carries about a fifth of global oil and gas supplies.
Adviser signals stronger role after war
Separately, senior adviser Mohammad Mokhber said the conflict could allow Iran to expand its influence over the strait.
“After the imposed war… by defining a new regime for the Strait of Hormuz, Iran will move from being under sanctions to a powerful position in the region and the world,” he said.
