## Summary

The [Middle Corridor](/en/entity/middle-corridor) (Trans-Caspian International Transport Route), [China](/en/entity/china) →
[Kazakhstan](/en/entity/kazakhstan) → Caspian → [Azerbaijan](/en/entity/azerbaijan)/[Georgia](/en/entity/georgia) → Turkey/Europe, recorded a 2025
volume dip to ~4.12m tons, down from a ~4.48m-ton peak in 2024, even as cargo has grown
roughly fivefold over seven years. The route carried ~77,000 TEU in 2025 against a 300,000-TEU
target for 2029. The dip exposes the structural ceiling: multiple borders, transshipments
and a Caspian-ferry bottleneck cap throughput. To break it, the World Bank approved an
$846m guarantee in early 2026 backing $1.4bn of financing for Kazakhstan's national railway,
and the $542m Darbaza-Maktaaral line is due in 2026. Capacity is projected toward ~10m
tons/year by 2027, if the bottlenecks clear.

## By the numbers

- ~4.12m tons, 2025 cargo (down from ~4.48m tons in 2024).
- ~5x, seven-year volume growth (~0.8m → ~4.5m tons).
- ~77,000 TEU, 2025 container volume; target 300,000 TEU by 2029.
- $846m, World Bank guarantee (early 2026) backing $1.4bn for KTZ rail.
- ~10m tons/yr, projected 2027 capacity if bottlenecks clear.

## Why it matters

The Middle Corridor is the only east-west route that bypasses both Russia and the
Red Sea/Suez, making it strategically prized by the EU and China alike. But the 2025 dip
shows demand-pull from elsewhere is not enough, without the financed rail and ferry
upgrades, the corridor risks staying a niche hedge rather than a trunk route.

## What to watch

- 2026 full-year volumes: a rebound or a confirmed plateau.
- Completion of the Darbaza-Maktaaral line and Caspian-ferry capacity adds.
- Whether the World Bank-backed KTZ financing converts into throughput.

### Kazakh state-aligned English daily
- **The Astana Times** (Kazakhstan, en) — Optimistic official-aligned framing: stresses the fivefold seven-year rise (0.8m to ~4.5m tons) and infrastructure wins, downplaying the 2025 dip, the corridor as a Kazakh strategic success story and Russia-bypass.

### critical Russia-Eurasia analysis
- **Carnegie Endowment (Politika)** (United States / Russia-Eurasia, en) — The sceptical counter-take: the much-touted corridor could prove a 'dead end', too many borders, transshipments and Caspian-ferry chokepoints to rival the northern route or Suez at scale; political hype outruns physical capacity.

### emerging-markets business
- **Oxford Business Group** (United Kingdom, en) — Frames the corridor as a disruption hedge: with Suez/Red Sea and northern Russia routes compromised, the Trans-Caspian gains strategic value despite its capacity limits, demand-pull from elsewhere, not its own efficiency.
