Key takeaways
- Track each grade on a consistent specification and commercial basis.
- Distinguish a product-price spread from a usable procurement alternative.
- Keep supplier quote dispersion separate from market movement.
- Refresh the complete delivered proposition before acting on a signal.
Local context for a delivered-price monitor
Fujairah's port describes a bunker network linking storage, loading facilities and anchorage deliveries. Port of Fujairah oil activities
For monitoring, this means the point in the supply chain matters. A storage-related product indication and a delivered vessel quote can move differently because their included scope differs. Label each observation instead of placing them in one undifferentiated price series.
For a current transaction, the comparable grade-spread observation is not provided; obtain current verified information. Record the observation time, grades, specification basis, delivery period and source status. If comparable authorised observations are unavailable, report that limitation rather than creating a spread from unlike figures.
Define the two prices before subtracting them
A useful spread compares specified observations on compatible terms. Identify the grade, location, quantity basis, currency, delivery period and included service scope for each. Explain any difference that cannot be normalised reliably.
For example, an MGO indication for a small prompt purchase and a VLSFO quote for a larger later delivery are not a clean grade-only comparison. Their difference may include quantity and timing effects as well as the product distinction.
The desk may still report both observations, but it should avoid assigning the whole difference to one cause. A transparent qualified comparison is more useful than a precise number with an ambiguous meaning.
Separate market movement from changing supplier terms
A supplier can revise its offer because the requested quantity or window changes. That revision is not automatically evidence that the wider market moved by the same amount.
Keep a comparable observation series where possible, then explain the transaction-specific adjustment separately. If the supplier adds a service charge, show its effect on complete delivered cost rather than relabelling it as a higher fuel price.
Likewise, different suppliers may quote different terms at the same time. The range among those offers describes the observed propositions, not necessarily a market trend. Review their inclusions and conditions before interpreting the dispersion.
A grade-spread monitoring matrix
| Observation difference | What to check | Appropriate conclusion |
|---|---|---|
| Different fuel grades | Accepted specification and comparable terms | A defined product spread, subject to stated differences |
| Different quantities | Minimums, tiers and fixed service costs | A purchase-size effect may be present |
| Different delivery periods | Validity and window basis | The comparison includes timing as well as product |
| Different supply-chain points | Product-only versus delivered scope | Missing services must be identified before ranking |
| Different credit terms | Payment basis and approved conditions | Cash requirements differ alongside the quoted price |
| Same-grade supplier range | Scope, firmness and availability | The range concerns the actual observed offers |
The matrix helps the desk explain why a headline signal may differ from the saving available on its own call.
Do not turn a spread into a substitution instruction
A larger price difference may justify asking whether an already acceptable procurement option has become more attractive. It does not establish that the vessel can substitute one fuel for another.
Use the responsible team's confirmed requirement and acceptance conditions. Do not infer the vessel's equipment, fuel capability or permitted arrangements from market prices. A cheaper unaccepted grade is context, not an executable saving.
If the requirement changes through the appropriate assessment, obtain a fresh complete offer for that requirement. The earlier spread can explain why the desk investigated, but the purchase should rest on the actual accepted proposition.
Fictional case: the spread widens because the basis changed
A fictional buyer's Fujairah dashboard shows a larger gap between its MGO and VLSFO observations. The team initially attributes the movement to a change in relative product prices.
Review shows that the latest MGO figure concerns a smaller, more urgent delivery than the previous observation, while the VLSFO series retains its original quantity and period. A separate fixed service amount is also included only in the new MGO total.
The buyer labels the comparison as non-comparable, obtains matching observations where available and preserves the original transaction-specific quote for the actual enquiry. The corrected report explains the evidence limitation without inventing a market narrative.
Connect monitoring to a concrete procurement action
A useful note might recommend refreshing an expiring offer, requesting a comparable grade quotation or checking a changed delivery inclusion. State the action and the unresolved question rather than recommending a purchase simply because a spread looks unusual.
Keep the source date visible. A recent discussion of an older quote does not make the observation current. If a private supplier response supplies the latest information, describe it as an authorised quotation rather than public market data.
The final decision should combine the accepted requirement, complete cost and usable window. Market monitoring supports that decision; it does not replace the confirmations needed to execute it.
Common mistakes
Do not calculate a grade spread from incompatible quantity or timing bases without qualification. Other errors include mixing upstream and delivered prices, interpreting one supplier's service adjustment as a market move and treating a lower-priced grade as an automatic substitute. A monitoring chart should expose its assumptions rather than hide them.

Frequently asked questions
Does a wider spread mean the vessel should switch fuel?
No. Suitability and the accepted requirement must be assessed by the responsible parties.
Can private quotes be used in monitoring?
Yes, with appropriate authorisation and clear source status. Do not describe them as public market assessments.
What if comparable observations are unavailable?
Report the limitation and seek a better-matched enquiry rather than manufacture a precise comparison.
Is supplier quote dispersion a market trend?
Not by itself. First compare scope, timing, quantity and the firmness of the offers.
