T&E: Overreliance on traditional bunker fuels costs shipping USD 395 million a day due to Iran conflict

The European Federation for Transport and Environment (T&E) on 27 March highlighted the adoption of green marine fuels would reduce the shipping industry’s exposure to fuel price shocks in future.
It noted shipping companies are spending an extra €340 million (USD 394.74 million) a day in additional fuel costs as a result of the latest conflict in the Gulf.
As 99% of the global fleet runs on fossil fuels, the industry is directly exposed to fuel price volatility and supply disruptions. Efficiency measures, electrification and e-fuels would reduce the industry’s exposure to price fluctuations.
According to T&E, marine fuel prices have escalated rapidly, with VLSFO reaching €941 per tonne in Singapore, up 223% since the start of 2026. At the same time, LNG prices have risen by 72% since early March. Since February 28, shipping companies have incurred more than €4.6 billion in additional fuel costs.
The development has made alternative fuels increasingly more competitive. As fossil fuel prices reach record highs again, the cost gap with e-fuels is narrowing.
T&E’s research shows that the cost gap between marine gas oil – one of the more expensive fossil fuels – and e-fuels has shrunk to near parity (+5%) in some ports.

While the trend may be temporary, it shows that the volatility of fossil fuel markets offsets much of the structural cost disadvantage of clean fuels.
“Chaos in the Strait of Hormuz is putting global maritime trade under the spotlight. But it’s on the oil markets where its impact will be felt the most. The war is costing the industry millions every day,” said Eloi Nordé, shipping policy officer at T&E.
“Some governments and parts of the industry have spent the last year bashing green maritime measures as being too expensive, yet those costs pale in comparison to this super-disruption.
“If anything, this crisis should be the catalyst for more investment in European e-fuels and greater uptake of energy efficiency measures to avoid fossil fuel shocks in the future.”
