South America Inland Waterway Transport Market Trends and Insights

Agricultural Export Volumes Shifting Toward River Corridors

River corridors are taking a larger role in agricultural export movements across the South America inland waterway transport market. The main driver is the cost difference between barges and trucks on long-distance commodity routes. Argentina’s river grain cabotage reached 805,805 tons in 2025, which was 18% above 2024 and the strongest result in 5 years. Total domestic cargo on the Paraguay-Paraná Waterway reached 8.49 million tons in 2025, increasing 5.8% from the prior year. On the Tapajós River, soybeans and corn accounted for 88.4% of 2025 throughput, and a 36-barge convoy demonstrated 110,000-ton carrying capacity per movement. These flows reduce dependence on trucking where navigable river access is available, while areas without it continue to face heavier pressure on road networks.

Inland-Port and Multimodal Integration Investments

Investment in inland ports and multimodal links is expanding the operating base for the South America inland waterway transport market. Brazil’s Merchant Marine Fund approved more than USD 706 million for maritime and river logistics projects in March 2026, including USD 80 million for 41 inland navigation projects in Amazonas State. The ministry also advanced an integrated concession covering port-access channels and inland waterway stretches at Rio Grande, Pelotas, and Porto Alegre. These developments support dredging, terminal capacity, and more coordinated access between river routes and seaports. They can also lower transfer friction for shippers that depend on multiple transport modes. Investment decisions remain tied to the clarity of concession terms and the timing of channel improvements.

Seasonal Draft Variability and Drought Exposure

Seasonal changes in water depth are a direct operating constraint for the South America inland waterway transport market. Brazil’s Geological Service projected in September 2026 that the Rio Negro at Manaus could fall to 12.31 meters during the dry season. This level approaches conditions that disrupted regional supply chains in 2023. CMA CGM raised its Amazon Low Water Surcharge to USD 2,315 per TEU for shipments to and from Manaus, effective October 2, 2026, because of falling river levels and the related cost of draft restrictions, floating piers, pilotage, and barge logistics. Low water can force operators to reduce cargo loads, alter convoy arrangements, or delay sailings. These actions can erode the cost advantage that river transport normally offers on high-volume freight movements.

The impact extends beyond vessel operators because exporters and importers also need to manage less predictable transit conditions. The Tapajos River could shift 3-5 million tons of soybeans from barges to trucks if channel dredging does not proceed, adding USD 29-48 per ton in freight costs and up to USD 164 million in supply-chain losses during the October through February dry season. Lower-draft vessels can extend operating windows and can reduce the severity of load restrictions. They cannot fully eliminate disruption during extreme drought. The South America inland waterway transport market therefore requires contingency capacity in roads, storage, terminals, and schedules. Navigation forecasts and more responsive dredging plans have become central to protecting cargo flows during dry months.

Other drivers and restraints analyzed in the detailed report include:

• Lower Fuel Intensity and Decarbonization Pressure Versus Road Freight
• Expansion of Paraguay-Parana Cross-Border Trade
• Fragmented Cross-Border Customs and Regulatory Procedures

Segment Analysis

Bulk cargo accounted for 91.15% of the South America inland waterway transport market share in 2025. The category is supported by the large volumes of soybeans, corn, iron ore, petroleum products, and other commodities that move efficiently in barge convoys. Dry bulk transportation is closely linked to grain harvests and export cycles. Liquid bulk transportation supports fuel distribution across the Amazon and Parana systems. Fertilizer movements on the Tapajós River increased 46.8% in 2025, while liquid bulk volumes on the same corridor rose 40% year over year. The figures show that bulk traffic includes a broader set of flows than grain cargo alone. Bulk operations remain dependent on terminal capacity, river depth, and access to export ports. Large convoys can create strong unit-cost advantages when channel conditions permit full loads. This structure helps explain the leading position of bulk cargo in the South America inland waterway transport market. The category also benefits from the region’s agricultural and extractive production base. Its concentration in high-volume commodities leaves it exposed to drought, harvest timing, and disruptions at key river access points. Operators are therefore investing in fleet availability and loading infrastructure that can maintain high cargo movement during favorable navigation periods.

Container Cargo is forecast to grow at a 5.81% CAGR through 2031 within the South America inland waterway transport market. Its growth reflects increased use of containers for industrial goods and consumer products moving between inland locations and coastal ports. Container services can provide a structured alternative to truck-only distribution where river terminals have suitable handling equipment. They can also improve connections between interior production zones and Atlantic deepwater terminals. The limited number of purpose-built container terminals along interior waterways remains a constraint. This limits faster adoption even where shippers could benefit from barge-based distribution. The first inland waterway concession auctions expected to close in 2026 were intended to support private investment in terminals and related river infrastructure. Better handling capacity can reduce the transfer burden between barges, trucks, and ocean services. Documentation standards and cargo classifications also shape planning decisions for container operators. The South America inland waterway transport market may see container growth accelerate where terminal investment is paired with reliable channel access. General cargo shippers will still compare river services with direct trucking on transit time and schedule certainty. Containerization therefore adds strategic value, but it does not displace the present bulk-led cargo structure.
