The World Bank estimated the development needs of the Trans-Caspian route at $28 billion.
At the 1st Azerbaijan International Investment Forum, held in September 2025, a World Bank representative stated that approximately $28 billion would be required to develop the Trans-Caspian International Transport Route (TITR) over the next 15 years. Of this, $25 billion is planned for modernizing rail infrastructure and $1.8 billion for developing port capacity. The route’s main bottleneck remains the junction of sea and rail transport due to limited capacity and differences in infrastructure across participating countries.
