Red Sea Tensions Lift Tanker Freight 60 Per Cent and Redraw Global Crude Routes

Tanker freight rates on key Atlantic and Indian Ocean routes have surged by 60 per cent over the past twelve months as Red Sea security risks force operators to take the long way round the Cape of Good Hope. Baltic Exchange data show the Worldscale rate for a Suezmax cargo from West Africa to Northwest Europe has risen to WS 145, compared with WS 90 a year earlier, while VLCC time charter equivalents have averaged above 55,000 US dollars per day.

For the City of London, where the world's largest concentration of maritime insurers, brokers and shipping financiers is based, the disruption has produced an unusual mixture of opportunity and anxiety. Lloyd's of London has revised its Joint War Committee listed areas to include broader portions of the southern Red Sea, and war risk premiums for transits have climbed to between 0.5 and 0.7 per cent of hull value, occasionally spiking higher after specific incidents involving Houthi attacks on commercial shipping.

The rerouting around the Cape adds roughly 3,500 nautical miles and 10 to 14 days to a voyage between the Arabian Gulf and Rotterdam. The additional bunker consumption, at very low sulphur fuel oil prices around 575 US dollars per tonne in Singapore, equates to an extra 600,000 US dollars per voyage. Charterers including BP Shipping, Shell Trading and Trafigura have been forced to lock in tonnage further forward, supporting period rates and squeezing spot availability.

The flow consequences are striking. Russian Urals heading to Asia, Iraqi Basrah Medium bound for Europe and US Gulf cargoes destined for India have all had their voyage economics reshuffled. Vortexa estimates that crude tonne-miles globally are up around 7 per cent year on year despite essentially flat traded volumes, an apparent paradox explained almost entirely by Red Sea avoidance.

For UK importers, the impact on landed crude costs has been material but manageable. With diversified supply from the North Sea, the United States, West Africa and Latin America, British refiners have substituted away from Middle Eastern grades during the tightest periods. Phillips 66 Humber reported on an investor call that its Middle East crude intake fell to 8 per cent of slate during the second quarter, the lowest level on record.

The Royal Navy continues to participate in coalition efforts under Operation Prosperity Guardian, with the Type 45 destroyer HMS Diamond having concluded a deployment in 2024 and further frigate deployments planned. Whitehall officials acknowledge, however, that military escort cannot eliminate the risk, and insurance markets reflect that reality.

Looking ahead, structural change appears likely. Even if a ceasefire reduces Houthi activity, many charterers and oil majors have indicated that they will return to the Suez route only gradually, conscious of reputational and crew welfare considerations. Tanker owners, particularly Greek and Norwegian operators with strong London relationships, have ordered around 90 new Suezmaxes for delivery during 2026 and 2027, a wager that the freight upcycle has further to run.
