The Trunk Navigable Way (VNT), spanning from the confluence of the Paraná and Paraguay rivers to its outlet to the Atlantic Ocean, constitutes Argentina’s main logistical infrastructure. Through this system flows the majority of the country’s foreign trade, so its performance directly conditions the competitiveness of the nation’s productive and export framework. In this context, the current debate goes beyond a specific tender and relates to how Argentina organizes its strategic logistical system in the long term.
The Waterway must be analyzed as an integrated system of transport and services whose planning, execution, and control impact logistical costs, territorial articulation, and the international insertion capacity of Argentine production. Its efficient operation helps improve operational conditions for various productive sectors and consolidates a more predictable and competitive logistical structure.
The new tender process emerges after a previous experience that did not conclude with an award. Compared to the previous scheme, the current process incorporates greater technical precision in defining works and target depths, execution schedules by stages, greater weighting of technical evaluation, reinforced mechanisms of transparency and control, along with increased participation from public and private actors. The schedule provides for the opening of bidding documents on February 27, 2026, at 1:00 p.m., which will initiate the formal evaluation of technical and economic offers. In general terms, the redesign seeks to orient the process toward verifiable operational results and greater predictability in execution.
One of the central criteria of the scheme is to favor navigation that brings the vessel closer to the cargo, optimizing the use of the fluvial and maritime system. This approach contributes to improving multimodal transport efficiency, reducing aggregate logistical costs, and strengthening systemic competitiveness. In this context, a single tariff system is maintained with the aim of preserving operational neutrality and predictability for users.
The bidding documents establish a staged tariff scheme linked to defined technical scopes. For the so-called Stage 0—which replicates current operational conditions—a tariff band between USD 3.8 and USD 4.2 per NRT (Net Register Tonnage) is foreseen, compared to the current tariff close to USD 4.3 per NRT. Updating the 2019 reference value (USD 3.06 per NRT) for U.S. inflation yields an approximate equivalent of USD 3.86, consistent with the lower limit set for this stage. For Stage 1, the band is between USD 4.65 and USD 5.05 per NRT, while for Stage 2 it is set between USD 5.78 and USD 6.18 per NRT.
Each stage defines specific technical scopes, including target depths and differentiated channel widths by section, linking tariff progression to concrete operational improvements. The band-based tariff scheme—aligned with international practices—seeks to reduce risks associated with economically unviable offers, improve coherence between investments and costs, and minimize the need for subsequent tariff renegotiations. Thus, tariff evolution is tied to technical results actually achieved. The documents also contemplate reviews in the event of significant tax changes, such as potential modifications to VAT treatment.
Its efficient operation contributes to improving operational conditions for various productive sectors.
The Waterway has economic and territorial impacts that extend beyond a single sector, reinforcing the need for institutional monitoring mechanisms. In this sense, the establishment of a Council for the Control of the Trunk Navigable Way represents progress aimed at strengthening technical supervision, improving contractual transparency, and facilitating the monitoring of investments and service levels. Recent experience indicates that the absence of stable control instances can limit the ability to anticipate operational deviations during execution.
The institutionalized participation of users in monitoring spaces should be understood as a contribution linked to system operation, where the availability of information about what is happening, combined with the incorporation of their perspectives, contributes to improving the quality of the process and system performance.
Navigable draft is a relevant variable in the efficiency of the fluvial logistical system. Operationally, greater depth allows increasing effective cargo per vessel and reducing the need for topping off at deep-water ports, with potential impact on unit logistical costs. However, the magnitude of this effect depends on specific operational conditions, the configuration of the port system, and market variables, so its evaluation requires defined technical scenarios and explicit assumptions.
The new scheme must be evaluated for its ability to generate concrete improvements over current operations. The greater technical definition of works, the staged tariff scheme, and the incorporation of control mechanisms represent significant advances in terms of operational predictability. However, the final results will depend on the quality of the offers, the effective execution of committed investments, and the actual functioning of the planned institutional mechanisms. Consequently, the value of the scheme lies not exclusively in the design of the bidding documents, but in the ability to translate it into verifiable operational improvements.
In a scenario where logistical competitiveness is increasingly relevant for international trade, the technical evolution and improved governance of the system are essential conditions to avoid relative cost increases for the economy. The central evaluation point will not be the award itself, but the ability to consolidate an efficient, technically controlled, and stable operational scheme over time.
The Paraguay–Paraná Waterway constitutes strategic infrastructure for Argentine productive development. Its evolution must be oriented toward improving logistical efficiency, strengthening operational predictability, and supporting an international insertion strategy based on production and foreign trade.
