Petrobras has emerged as one of the biggest gainers in the crude tanker market during the first half of 2026, as disruption in the Middle East shifted tanker demand towards Atlantic Basin crude flows, according to Poten & Partners’ Tanker Midterms report.
Charterer Ranking Shifts
Poten & Partners reported that Unipec retained its position as the largest reported dirty spot charterer, booking 244 fixtures. However, its dominance in the VLCC segment eased significantly: its VLCC fixture count fell from 317 in the first half of 2025 to 217 in the same period of 2026 — a drop of over 30%.
Petrobras, meanwhile, moved in the opposite direction. The Brazilian state-controlled oil company increased its VLCC fixture count from 52 to 73, a 40% rise, climbing from sixth to second place in Poten’s overall dirty tanker charterer ranking. By cargo volume, Petrobras placed ahead of TotalEnergies, Chevron, and ExxonMobil, and was only beaten by Unipec.
Market Context
Poten attributed the broader slowdown in tanker activity to the Middle East conflict, which effectively removed the Arabian Gulf from the spot market for around four months. The consultancy also pointed to lower Chinese crude imports following the disruption, weighing on demand for Middle East cargoes. This rebalancing of crude flows toward the Atlantic Basin has directly benefited Petrobras as a major exporter from Brazil.

Operational Implications for Shippers and Logistics Managers
The shift in tanker demand has direct implications for crude oil logistics. With Unipec scaling back VLCC spot fixtures, capacity availability on the Middle East-to-Asia route may tighten, while Atlantic Basin routes — particularly from Brazil to China and other Asian destinations — could see increased competition for tonnage. This may influence freight rates, as Petrobras' higher fixture count suggests sustained demand for vessels on the Brazil-Asia lane.
For freight forwarders and logistics managers handling crude oil shipments, the changing charterer landscape means adjusting procurement strategies. Those relying on Middle East crude may face longer lead times or higher costs if VLCC supply tightens, while Brazil-origin cargoes may benefit from more frequent sailings and potentially more competitive rates.
Watch List
- Middle East geopolitical situation: The duration and intensity of the conflict will continue to affect Arabian Gulf spot market participation and global crude tanker demand.
- Chinese crude import levels: Lower Chinese imports have weighed on Middle East cargo demand; any recovery could shift the balance back toward Unipec and other Asian charterers.
- Petrobras’ chartering strategy: If Petrobras sustains its increased fixture activity, it could cement its position as a top-tier charterer, further reshaping freight dynamics on Atlantic vs. Pacific routes.
