This was the week bunker-price risk returned to the front of the procurement conversation.
The quarterly global VLSFO outlook rose by about $100/mt after hopes of a quick recovery in Strait of Hormuz flows faded. In ARA, fuel-oil stocks improved but prompt availability still required planning, while gasoil inventories fell to a four-year low. Rotterdam biofuel prices moved in the opposite direction as feedstock costs dropped.
But the week was not only about price. Sulphur-related bunker claims rose sharply in China, Zhoushan reopened after an eight-day weather disruption, and new vessels and infrastructure showed the alternative-fuel supply chain continuing to develop.
Here are the ten developments worth carrying into next week.
1. The Q3 bunker-price outlook rose by about $100/mt
Ship & Bunker raised its third-quarter Global 20 Ports VLSFO forecast to $705/mt, from $604/mt in its July outlook. The change followed the US Energy Information Administration increasing its Q3 Brent forecast from $74.03/bbl to $85.21/bbl.
The important part is why the forecast moved. July's lower view assumed disruption around the Strait of Hormuz would ease. Instead, the EIA now expects severe transit constraints to persist through August, with large global inventory draws keeping prices elevated while flows recover.
A forecast is not a quote, and the market can move again. It is still a useful warning against treating last month's assumptions as today's buying plan.
The Bulugo lens: every comparison needs a timestamp, delivery window and clear validity period. When the underlying view changes by $100/mt in a month, quote history becomes decision evidence, not admin.
2. ARA fuel-oil stocks improved, but prompt supply stayed tight
ARA's independently held fuel-oil stocks averaged 5% higher in August so far than July, reaching 4.24 million barrels. Imports rose sharply to 381,000 b/d, while exports fell.
That does not mean prompt stems became easy. Fuel-oil inventories remained 34% below February levels, and buyers were still advised to allow roughly five to seven days to receive competitive offers from a broad supplier set.
The grade split also matters. Independent gasoil inventories fell 5% to 11.61 million barrels, their lowest level in just over four years.
The Bulugo lens: aggregate stock data and deliverable supply are not the same thing. Buyers should capture grade, quantity, delivery date and acceptable alternatives before asking the market to compete.
3. Rotterdam biofuel prices fell as feedstocks became cheaper
Rotterdam's B30-VLSFO price fell $14/mt over the week, while conventional VLSFO was broadly unchanged. B30-LSMGO also edged lower despite a $45/mt rise in conventional LSMGO.
The driver was feedstock. Assessed POMEME and UCOME barge prices each fell $92/mt, and Rotterdam's B100 bunker price dropped $31/mt.
Regulation is part of the effective price. Dutch RED III compliance tickets and FuelEU Maritime demand can change the economics after conventional price, carbon exposure and compliance value are considered. In some circumstances, lower-premium biofuel can approach cost parity once EU ETS costs are included.
The Bulugo lens: comparing only dollars per tonne can hide the useful answer. A bunker-price comparison increasingly needs fuel pathway, certificate, carbon intensity and compliance assumptions alongside the physical price.
4. ARA and Mediterranean lead times remained uneven
ENGINE's regional outlook advised around five to seven days for good supplier coverage in ARA. The Gibraltar Strait required roughly seven to ten days, Las Palmas ten to twelve days, and Port Louis ten to fourteen days for VLSFO and LSMGO.
Elsewhere, availability was less constrained. Hamburg could generally cover grades within five days, while Istanbul required about four days for VLSFO and one to three days for distillates.
This is why a port name and indicative price are not enough. The commercially sensible port can change when a vessel's route, notice period and grade flexibility are taken into account.
The Bulugo lens: procurement should expose delivery confidence next to price. A cheaper indication that cannot meet the vessel is not the cheaper option.
5. Sulphur-related bunker claims more than tripled
Marine insurer Gard said sulphur-related bunker claims more than tripled in the first half of 2026 compared with a year earlier. The total was already about 40% above all of 2025.
The rise came as Chinese authorities increased fuel sampling, onboard inspections and checks of bunker delivery notes, test reports and fuel-management records in major Bohai Sea ports.
In one case highlighted by Gard, fuel was measured at about 2.51% sulphur. The vessel was ordered to stop using it and prepare a disposal plan. Non-compliant ships can also face fines.
The Bulugo lens: the quote is only the beginning of the evidence chain. Specification, delivery note, representative sample, test result and supplier communication should remain connected to the stem.
6. Zhoushan resumed full bunkering after eight days
Bunkering at Zhoushan's Tiaozhoumen and Xiazhimen outer anchorages resumed on Friday after an eight-day suspension caused by Typhoon Dolphin. More sheltered anchorages had reopened earlier in the week.
Weather disruption is familiar, but the operational lesson is easily lost. A market can be competitively priced and well supplied while being temporarily inaccessible at the exact location or time a vessel needs it.
The Bulugo lens: buyers need live operational context and a fallback plan. Alternative anchorage, delivery window and port options should be agreed before disruption turns into a last-minute procurement exercise.
7. Singapore bunker sales reached a four-month high
Singapore's conventional and biofuel bunker sales rose to 4.67 million mt in July, the highest since March and the third consecutive monthly increase. VLSFO volumes rose 5.9% month on month to 2.33 million mt.
The alternative-fuel picture was mixed. Biofuel blends rose 5.3% from June but remained 67% below July 2025. LNG sales reached 58,690 mt, up 41.5% year on year. No methanol or ammonia sales were recorded during the month.
Singapore also recorded 3,675 bunker calls, while average stem size fell to 1,271.6 mt.
The Bulugo lens: headline hub volume can conceal very different product markets. Buyers and suppliers need grade-level activity, not a single number labelled “bunker demand”.
8. A methanol-capable boxship entered Northern European service
MPC Container Ships christened the 1,250 TEU DP World Southampton, which will operate in Northern Europe under a seven-year time charter with DP World.
The ship combines a methanol-capable dual-fuel engine with shore-power connectivity. That gives the operator more than one route to reducing emissions, depending on fuel availability, berth infrastructure and voyage requirements.
Capability is not the same as regular low-carbon operation. The commercial test will be whether suitable methanol can be sourced with the required sustainability evidence, at the required ports, on workable terms.
The Bulugo lens: “methanol capable” creates a procurement requirement. Supplier discovery needs to show location, volume, pathway, certification and delivery method before capability becomes usable.
9. The methanol-capable bunker fleet kept expanding
Fratelli Cosulich launched Carlotta Cosulich, an IMO type II bunker tanker with coated cargo tanks and provision for future methanol propulsion. It is part of a wider fleet investment that includes methanol-capable and LNG bunker tankers.
The group expects two remaining vessels in the programme to arrive by May 2027 and is also assessing LNG, methanol and ammonia opportunities with IINO Lines.
The distinction matters: a vessel being methanol-ready does not mean it is already operating on methanol. It does show that physical-delivery capability is being designed with future products in mind.
The Bulugo lens: alternative fuels need alternative-fuel logistics. A credible supplier profile should describe delivery assets and conversion status precisely, without turning “ready” into “available”.
10. Shore power moved into a new region
DP World Callao became the first port in Latin America to offer shore power. Compatible vessels at the South Pier Container Terminal can use electricity instead of auxiliary engines while alongside.
The operator expects the installation to avoid more than 6,300 tonnes of CO2 emissions per year. The actual climate benefit will still depend on the electricity mix and vessel use.
Germany also opened a €70 million programme supporting low- and zero-emission inland vessels and the charging, hydrogen, ammonia and methanol infrastructure needed to operate them.
The Bulugo lens: marine-energy procurement is expanding beyond the bunker stem. Vessel compatibility, port infrastructure and the evidence behind the energy source increasingly belong in the same operating picture.
What this week means for buyers and suppliers
The market sent three different signals at once:
- geopolitical disruption lifted the forward price view;
- physical availability still varied sharply by grade, port and notice period; and
- lower biofuel feedstock costs improved some alternative-fuel economics.
That makes static price comparison less useful, not more. Buyers need an auditable way to compare what can actually be delivered, when, to specification and with the required compliance evidence. Suppliers need a structured way to show that capability without relying on another round of inbox archaeology.
That is the procurement gap Bulugo is built to close: turning price, availability, supplier capability and evidence into one usable decision.
