Naphtha Arbitrage Squeezed by Tanker Freight

The Middle East war has upended Asia's naphtha market, with the March halt at Hormuz forcing a shift in trade flows. According to shipbroker Gibson, the Gulf normally supplies over half of Asia's imports, but the disruption has squeezed the naphtha arbitrage as freight costs rise (Hellenic Shipping News). For maritime service providers, this means changing tanker port calls and new outreach priorities.

What happened to Asia's naphtha supply?

The war in the Middle East has upended Asia's naphtha market. With the Gulf normally supplying over half of Asia's imports, the March halt at Hormuz forced buyers to look elsewhere (Hellenic Shipping News). The result is a longer-haul trade that ties up tanker capacity and lifts freight rates.

Why freight costs are squeezing the arbitrage

Naphtha arbitrage depends on the price gap between regions covering the cost of freight. When freight rises, that gap narrows or closes. According to Gibson, the shift has squeezed the naphtha arbitrage as freight costs rise (Hellenic Shipping News). Tanker rates were mostly higher this week, adding pressure on traders' margins (Hellenic Shipping News).

What this means for tanker port calls

Longer voyages and rerouted cargoes change the pattern of tanker port calls at Asian discharge ports. Vessels that would have loaded in the Gulf now load in other regions, altering ETA (Estimated Time of Arrival) schedules and creating new opportunities for port agents, bunker suppliers and chandlers to serve these ships.

At the same time, the broader tanker market remains volatile. A 2023 study in the International Journal of Finance & Economics found that oil price uncertainty and the future correlation of oil and dirty-tanker returns are negatively associated, with the effect more pronounced in highly volatile periods (Wiley). That volatility makes planning harder for suppliers who rely on steady port traffic.

Other market signals for service providers

Container rates from Asia to the US were mixed this week as capacity tightens and import demand slows, with West Coast rates at $7,515-8,365 per FEU (Hellenic Shipping News). In dry bulk, the Capesize market gathered momentum through the week, with stronger fixing activity across both basins (Hellenic Shipping News). Drewry's Intra-Asia Container Index increased $46 to $1,504 per 40ft container, holding steady as congestion eases (Hellenic Shipping News). These moves affect vessel schedules and port call volumes across regions.

Regulatory and trade policy shifts

The US Trade Representative is suspending port fees for Chinese vessels by two months and will accept public comment, delaying implementation that was set for 10 November (Hellenic Shipping News). For port agents and suppliers, this creates uncertainty around vessel routing and fee structures. Meanwhile, Russia is advancing a new LNG supply pivot to Africa, targeting rising energy demand on the continent (The Maritime Executive). New LNG trade routes could bring additional gas carrier port calls to African and other ports.

How should maritime service providers respond?

Chandlers, bunker suppliers, port agents and repair yards should monitor tanker movements closely, especially at ports affected by changing naphtha flows. Key actions:

• Track vessel arrivals and ETAs at your target ports to identify new tanker calls.
• Reach out to ship managers and technical superintendents before vessels arrive, offering services tailored to longer voyages.
• Adjust stock and staffing for potential shifts in vessel types and volumes.
• Use digital tools to automate vessel monitoring and outreach, reducing manual research.

How VesselReach helps

VesselReach turns vessel movements at your target ports into conversations with decision-makers. It detects vessels near your ports and scheduled arrivals, so you can reach ship managers and procurement teams before the vessel docks. Its AI identifies the right company behind each vessel and finds decision-makers by role, while multichannel outreach by email, WhatsApp and phone keeps your pipeline moving. Automated follow-ups and AI enquiry handling ensure no lead is missed.
