The planned IPO of Kazakhstan’s national railway operator, Kazakhstan Temir Zholy (KTZ), once presented by the authorities as one of the largest public offerings in Central Asia, is increasingly being viewed as an attempt to stabilize the company’s balance sheet amid rapidly rising debt. The share sale, expected in late 2026, may turn out to be less a growth story than a mechanism for refinancing the obligations of the state-owned carrier.
During parliamentary hearings on April 24, company executives acknowledged that one of the key objectives of the IPO is to raise funds to service KTZ’s growing debt burden.
According to official company and government data, KTZ’s nominal debt has risen sharply. It stood at about $5.7 billion in early 2024, and roughly $8 billion by 2025. By April 2026, it had reached 4.7 trillion tenge, or about $10.4 billion. The increase reflects heavy borrowing for rolling stock, infrastructure modernization, and the expansion of Kazakhstan’s transit capacity, including projects linked to the Middle Corridor. It also reflects the cost of maintaining below-market tariffs for socially important domestic freight.
Kazakhstan’s Supreme Audit Chamber warned as early as 2024 about risks related to the company’s financial sustainability. However, the authorities and KTZ management argue that large-scale borrowing was necessary to prevent an infrastructure crisis.
According to official estimates, borrowed funds include about $4.9 billion for renewing rolling stock, including locomotives and railcars, and about $2.3 billion for modernizing railway infrastructure.
The currency structure of the debt represents an additional vulnerability. More than half of the company’s obligations are denominated in foreign currencies, making KTZ highly sensitive to fluctuations in the tenge. Any weakening of the national currency automatically increases debt servicing costs and reduces the operator’s profitability.
Potential investors face another challenge: historically, KTZ has served not only as a commercial company but also as an instrument of state social policy. A substantial share of revenues from China-Europe transit freight is used to subsidize unprofitable domestic passenger transport and the transportation of socially important goods within Kazakhstan.
This cross-subsidization mechanism limits the company’s ability to generate free cash flow. Grain transportation under regulated tariffs alone generated losses of approximately $95 million (44 billion tenge) for KTZ in 2024.
In an effort to improve the company’s attractiveness ahead of the IPO, KTZ has initiated large-scale tariff increases for mainline railway services. Beginning in April 2026, transportation tariffs for coal, grain, and iron ore were doubled.
However, the move risks adding to costs in Kazakhstan, where railway tariffs directly affect the cost of food, electricity, and industrial goods. Annual inflation stood at 12.2% in January 2026, adding to concerns that higher railway tariffs could feed into wider price pressures.
Additional inflationary pressure may come from the expiration of the government’s moratorium on utility tariff increases, after which household utility bills in some regions could rise by 10-20%.
Against this backdrop, analysts do not rule out a return to tighter state regulation of tariffs, a development that could once again limit the ability of natural monopolies to generate returns on investment.
The planned KTZ listing is therefore increasingly perceived as an attempt to spread financial risk beyond the state rather than as a classic growth-oriented IPO. In practice, the burden could fall on investors, freight customers facing higher tariffs, consumers exposed to price increases, and the state, which remains responsible for politically sensitive transport services.
The involvement of minority shareholders could provide the sovereign wealth fund Samruk-Kazyna with additional political justification for unpopular reforms, including further tariff liberalization and efforts to improve the company’s commercial efficiency.
The main investment thesis will likely center on KTZ’s role in the Trans-Caspian International Transport Route, the so-called Middle Corridor. The route links China and Europe through Kazakhstan, the Caspian Sea, Azerbaijan, Georgia, and onward routes through Turkey or the Black Sea. Interest has increased since Russia invaded Ukraine, as shippers and governments look for alternatives to northern routes through Russia.
That gives KTZ a credible growth story. Middle Corridor freight volumes have risen, and international lenders have identified Kazakhstan as one of the countries that could benefit from better rail, port, and logistics links. But the same corridor also requires heavy spending on infrastructure, equipment, coordination, and bottleneck removal. In other words, the Middle Corridor is both the main reason investors may look at KTZ and one reason the company still needs capital.
Nevertheless, KTZ’s high debt levels, ongoing capital expenditure needs, and continued state control may limit investor appetite. As long as the government remains the majority shareholder, the company will have to balance commercial profitability against its social obligations.
For investors, KTZ offers exposure to one of Eurasia’s most important transit networks. But unless Kazakhstan separates the company’s commercial operations from its social obligations and creates clearer compensation mechanisms for regulated transport, the IPO may look less like a straightforward bet on the Middle Corridor than an invitation to help refinance a state company’s problems.
