Türkiye is raising the transit fee charged on international vessels passing through the Turkish straits by almost 15% as of July, a top official said on Friday.

The fee, calculated under the 1936 Montreux Convention in "gold francs" and based on vessels' net registered tonnage, is updated annually.

"We will update the fee charged per net ton from ships, which was $5.83 in 2025, to $6.70 as of July 1," Transport and Infrastructure Minister Abdulkadir Uraloğlu said.

Türkiye had charged $0.80 per net ton from 1983 until Oct. 7, 2022, Uraloğlu told Anadolu Agency (AA).

The fee was revised to $4.08 per net ton in 2022. It was later raised to $4.42 from July 2023, $5.07 from July 2024, before being hiked to $5.83 last year.
