The Middle Corridor's Next Test Is Capacity, Not Geography

Georgia’s ambitions to become a major transport gateway between Europe and Asia are gathering momentum. At the Georgia International Maritime Forum in Batumi earlier this month, Prime Minister Irakli Kobakhidze outlined plans to mobilise approximately $7 billion for transport and logistics infrastructure by 2032. The programme includes modernising the country’s railway network, expanding port capacity, developing the Anaklia Deep Sea Port and improving critical highway connections. The government aims to double railway and port capacity while halving cargo transit times.

The announcement comes as the Middle Corridor, also known as the Trans-Caspian International Transport Route, attracts renewed investment from governments, multilateral lenders and logistics operators seeking to diversify Eurasian trade. Running through Central Asia, across the Caspian Sea and into the South Caucasus, the route offers an alternative to traditional northern connections through Russia. Its commercial importance has grown since the invasion of Ukraine in 2022, although its infrastructure remains substantially less developed than that of the established northern route.

Yet the geography of the Middle Corridor is increasingly well understood. The more consequential question is whether its railway networks, Caspian shipping services, border crossings and Black Sea terminals can operate as a coordinated logistics system rather than a collection of national infrastructure projects.

Georgia’s investment ambitions meet a wider infrastructure challenge

Georgia has placed transport connectivity at the centre of its economic development strategy. Its proposed investment programme aims to double rail and port capacity while reducing cargo transit times. The Anaklia project is intended to expand deep-water access on the Black Sea, complementing existing facilities at Poti and Batumi and improving the country’s connections to European markets.

The investment case is supported by growing freight demand. According to research published by PMCG on 8 September, total transit cargo through Georgia more than doubled between 2018 and 2025, reaching 13.7 million tonnes. Of that, approximately 4.6 million tonnes travelled along the Middle Corridor. However, the study also found that most Middle Corridor traffic through Georgia was associated with regional trade rather than long-distance shipments between China and Europe.

This distinction matters commercially. A route capable of moving regional bulk commodities is not automatically equipped to handle regular, time-sensitive container services between Chinese manufacturing centres and European distribution networks. The latter require predictable sailing schedules, reliable railway connections, integrated customs procedures and dependable end-to-end pricing. For freight forwarders, manufacturers and retailers, consistency can be as important as headline transit times.

Recent financing is beginning to address some of these constraints. In June, the World Bank approved $372 million for Georgia’s Trans-Caspian Transport Corridor project, part of a wider investment programme exceeding $750 million. The financing includes new energy-efficient electric locomotives for Georgian Railway, road improvements and institutional reforms intended to increase freight capacity and improve operational reliability.

But Georgia cannot resolve the corridor’s capacity constraints independently. A faster railway west of the Caspian provides limited commercial advantage if cargo remains delayed at its eastern ports or cannot secure a scheduled vessel crossing. The investment challenge extends across the entire transport chain, where the performance of one country’s infrastructure is increasingly dependent on developments in its neighbours.

The Caspian remains the critical connection

Investment on the eastern side of the Caspian is equally important. The European Bank for Reconstruction and Development and the European Union announced financing of up to €45 million for Kazakhstan’s Aktau port in 2025. The programme includes extending two berths and acquiring weather-resilient ship-to-shore cranes, with the objective of doubling the port’s container-handling capacity and improving its ability to accommodate growing transit traffic.

These improvements address a longstanding weakness of the Middle Corridor: cargo must transfer between different transport modes several times before reaching its destination. Each transfer introduces additional handling costs, scheduling dependencies and potential delays. Limited ferry capacity, irregular maritime services and insufficient coordination between railways and ports can undermine investment elsewhere along the route. The OECD’s assessment of Middle Corridor infrastructure identified precisely these problems, highlighting deficiencies in vessel capacity, terminal equipment and multimodal connections as obstacles to predictable transit times.

The issue is not simply constructing larger terminals. Additional container capacity at Aktau must be matched by reliable shipping connections to Azerbaijan, sufficient onward rail capacity and efficient access to Georgian ports or Türkiye. Without coordinated improvements, expanding one terminal risks transferring congestion to the next.

This makes maritime capacity on the Caspian a particularly important indicator of the corridor’s development. Rail investment in Kazakhstan and Georgia can increase the volume of cargo arriving at the coast, but that cargo must still cross the sea before continuing west. Shipping capacity, port productivity and railway timetables therefore need to develop together if the corridor is to offer a credible service to international customers.

A corridor attracting competing interests

The commercial opportunity is attracting interest well beyond the countries through which the corridor passes. On 23 September, Georgia’s economy minister met China’s transport minister to discuss cooperation covering railways, maritime infrastructure, roads and civil aviation. The Anaklia Deep Sea Port featured prominently in the discussions, reflecting its potential role in strengthening connections between Asian production centres and European markets.

Europe has its own reasons to support alternative Eurasian transport links. The OECD’s February 2026 study on measuring Trans-Caspian connectivity underlines the importance of evaluating corridors through measurable operational performance rather than infrastructure investment alone. For businesses considering alternative supply chains, this means assessing actual transit times, reliability, costs and the performance of individual connections.

For Georgia, the immediate opportunity is to translate international interest into functioning transport infrastructure and sustained freight demand. Its investment programme could strengthen the country’s position within Eurasian trade, but the commercial outcome will depend on investment and operational coordination across the entire corridor.

Financing commitments and construction announcements are important indicators of progress, but neither guarantees higher throughput, lower logistics costs or greater reliability. The critical question is whether the new infrastructure will operate as a connected system capable of attracting regular commercial services.

What businesses should monitor

The next phase of the Middle Corridor’s development will require closer attention to operational performance rather than investment announcements alone. Georgian Railway’s locomotive procurement, network modernisation and freight performance should be monitored alongside construction milestones at Anaklia and handling capacity at Poti. These developments will indicate whether Georgia’s investment programme is translating into additional capacity.

Across the Caspian, vessel availability, sailing frequency, berth productivity and container dwell times at Aktau, Kuryk and Baku will provide a more immediate measure of the corridor’s ability to handle increasing traffic. Additional terminal capacity will have limited commercial value without corresponding maritime capacity and coordinated onward rail services.

Transit times and costs will remain equally important. Businesses should compare end-to-end delivery performance, tariff structures and border clearance times against established northern and maritime routes. Published transit-time targets must be distinguished from actual performance across different cargo categories and origins. A service offering occasional rapid deliveries is not necessarily suitable for supply chains requiring consistent weekly departures and predictable arrival windows.

Investment delivery will also warrant attention. Financing commitments, construction contracts and operating arrangements should be assessed together, particularly where announced projects depend on cooperation across several jurisdictions. Delays at one node can diminish the benefits of capacity improvements elsewhere.

The Middle Corridor’s development is increasingly a question of execution rather than ambition. Georgia’s investment plans, Caspian port expansion and growing international interest demonstrate the scale of the opportunity. But the corridor’s commercial success will ultimately be measured not by the number of projects announced or the capacity of individual terminals, but by its ability to move freight consistently from origin to destination.

For shippers and investors, that is the distinction that matters: a geographically attractive alternative is not necessarily a commercially dependable one.
