Red Sea Shipping Tensions Add 60% to Tanker Freight Costs and Reroute Global Flows, Guyana Logistics Impact

Tanker freight costs on key benchmark routes have climbed by close to 60 per cent compared with pre-crisis levels, driven by the persistent rerouting of vessels away from the Red Sea and Bab el-Mandeb chokepoint. The Baltic Exchange's Dirty Tanker Index has been trading at multi-year highs, with Very Large Crude Carrier (VLCC) rates on the Middle East-to-China route averaging Worldscale 75, up from Worldscale 45 a year earlier. Suezmax vessels on the West Africa-to-Europe route are also commanding sharply higher rates.

The root cause is well known. Houthi forces in Yemen have continued to target commercial shipping transiting the southern Red Sea, despite the presence of the United States led Combined Task Force and the European Union's Operation Aspides. Maersk, Hapag-Lloyd, Frontline, Euronav and several other major carriers have rerouted vessels around the Cape of Good Hope, adding between 10 and 14 days to voyage times and increasing bunker fuel consumption by roughly 35 per cent.

For Guyana, the impact is mixed. On the positive side, Guyanese crude grades shipped from the Stabroek block FPSOs travel on Suezmax tankers westward to North America and eastward across the Atlantic to Europe, avoiding the Red Sea entirely. This means Guyanese cargoes have become relatively more attractive to European refiners who previously relied on Middle Eastern barrels arriving via Suez. Refineries in Italy, Spain and the Netherlands have all increased their take of Liza, Unity Gold and Payara crudes over the last year.

On the negative side, the higher freight environment also pushes up the cost of importing refined products. Guyana, lacking a domestic refinery, still imports nearly all of its diesel, gasoline and jet fuel. The Guyana Energy Agency has confirmed that retail fuel prices at Guyoil and Rubis stations would be at least US$0.08 per litre higher than they otherwise might be, were it not for the temporary excise tax adjustments approved by the Ministry of Finance to cushion consumers.

The disruption has also revived discussions about energy security and strategic petroleum reserves. Cabinet has been weighing whether to mandate a 30-day strategic stockpile of refined products, modelled on similar reserves held by Caribbean neighbours like Barbados. The cost would not be trivial, estimated at over US$140 million for initial set-up, but the buffer would provide critical insulation against future shipping shocks.

On the upstream side, the offshore vessels supplying the Stabroek block, including the Saipem Constellation and the Stena DrillMAX, are not directly affected, since their voyages from European and Asian shipyards have largely already been completed. However, spare parts, subsea trees and umbilicals being shipped from Norwegian, Dutch and Singaporean suppliers are facing both higher freight and longer lead times. ExxonMobil's procurement team has reportedly increased buffer inventory at the Guyana Shore Base by close to 20 per cent to mitigate any operational disruption to ongoing drilling and completion campaigns.
