Recent indications from Vitol Group signal that rising crude oil exports through the Strait of Hormuz will not alleviate the ongoing shortage of high-sulfur fuel oil (HSFO). Kieran Gallagher, the Asia head of Vitol, noted at a conference in Singapore that the supply tightness is exacerbated by conflicts in the Middle East and Ukraine.
Supply Shortages
The conflicts in the Middle East have curtailed HSFO supply from the Persian Gulf, with an estimated reduction of 800,000 tons per month. Concurrently, disruptions in Ukraine have led to a decrease of 1 million tons per month from Russian refineries. Industry experts had anticipated that higher crude exports would alleviate HSFO supply challenges; however, Gallagher emphasized that increased crude output does not necessarily convert into higher availability of HSFO.
Gallagher explained that refiners are prioritizing production of other petroleum products, such as diesel, due to exceptional refining margins. This shift is impacting the availability of HSFO for bunkering, as refiners maximize throughput to capture higher returns from value-added products.

Market Dynamics
The reduction in HSFO availability has resulted in significant price increases in Asia, where the cost of HSFO has reached levels not seen since April, according to data from ClearLynx LLC. As the world’s largest supplier of ship fuel, Singapore’s market dynamics reflect intense competition for refining components required to produce low-sulfur fuel oil (LSFO) grades, further complicating the supply issue.
In contrast, the LSFO market appears less strained, bolstered by ongoing exports from China and increased production rates from Nigeria’s Dangote refinery, which has been actively exporting up to three Suezmax cargoes per month. However, pressure in this segment persists, largely due to fierce competition for blending components that enhance fuel quality.
The Operational Read
The ongoing supply crunch in high-sulfur fuel oil presents a challenging operational environment for shipping operators. The constraints resulting from geopolitical tensions and refinery priorities necessitate strategic adjustments for fleet operators. As HSFO prices soar, companies may encounter increased operational expenses, compelling them to re-evaluate chartering terms and bunker strategies. Observers should monitor refinery trends, particularly regarding Saudi crude exports, as fluctuations may influence fuel availability and pricing dynamics in the months ahead. Furthermore, the balance between HSFO and LSFO will be critical for operators in maximizing efficiency while managing costs.
