London-listed fund Tufton Assets has chartered out its MR product tanker Mia Grace for 12-14 months at US$ 39,000 per day, 81% above its current charter of US$ 21,500. One ship, but it fits a tight product tanker market that could make diesel supply into the ARA region more expensive. For Dutch buyers the issue is mainly fuel surcharges: before Q4 renewals, check how the surcharge formulas in your transport contracts work, and request Q1 2027 quotes with different fuel pricing models.
What is actually happening
Tufton Assets published a Charter Update via RNS on 29 September 2026. According to Splash247 and QuotedData, the Mia Grace, a chemical and oil products tanker, has been chartered for 12-14 months at US$ 39,000 per day. The charter starts around 30 September; the current rate is US$ 21,500 per day. Tufton attributes the tightness to sanctions and disruption around the Strait of Hormuz: fewer sanctions-compliant vessels are available, and that effect has spilled over from crude tankers into product tankers.
Scope: one time charter from one shipowner — not a spot freight rate and not a market index.
Who is directly affected
Directly affected are charterers of MR tankers: oil traders, oil majors and distributors moving diesel by sea. In mid-September the ARA region imported around 157,000 barrels of gasoil per day, 41% of it from the US.
Probably not directly affected: container shippers (a different freight market) and companies buying diesel with a fixed price and a volume guarantee. Even a fixed price does not fully protect: surcharges, limited price validity or revision clauses can still move with the market, especially on renewal.
The second-order effect
Orbecta analysis. Possible chain: more expensive MR tankers make transatlantic diesel supply more expensive, which could push up the ARA wholesale price and feed through the diesel index into carriers' fuel surcharges. This only happens if the tightness persists and the ARA region remains dependent on imports.
On magnitude: assume a round voyage of 30 days and a vessel carrying about 37,000 tonnes of cargo. The difference of US$ 17,500 per day then comes to roughly US$ 525,000 per cargo, or about US$ 14 per tonne, roughly 1.2 US cents per litre of diesel. This is indicative, calculated before conversion into euros, and a time charter is not the same as a voyage cost. Freight contributes, but the diesel price itself probably moves more.
Dutch procurement impact
- Directly possible: transport contracts with a fuel surcharge linked to a diesel index, for road haulage, inland shipping and your own fleet.
- Indirect: chemicals and agrifood buying liquid bulk CIF via Rotterdam or Antwerp. Suppliers may pass higher freight costs into their quotes.
- Possible: fuel-related claims from logistics providers at Q4 renewals.
According to Insights Global, ARA gasoil and diesel stocks stood at 1.68 million tonnes on 10 September 2026, 4% higher than a week earlier, due to more imports from the US. The September average up to 28 September was around 255,000 barrels above August, at 12.33 million barrels. So no shortage signal; the risk lies mainly in price.
Company exposure: not yet calculated — link spend and supplier data.
What is certain and what remains uncertain
What is certain: the Mia Grace charter at US$ 39,000 per day (+81%) and the causes Tufton cites. In mid-September 41% of ARA gasoil imports came from the US.
What remains uncertain: whether this rate is representative of the spot market, and how much feeds through into the ARA diesel price. The scan signal reports, citing OilPrice.com, record diesel prices in the US. Orbecta has not verified this itself.
What to watch: weekly ARA gasoil stocks (Insights Global), the share of imports from the US, the level of the diesel index in your surcharge formulas and surcharge announcements from your carriers.
What you can do now
- Logistics procurement, before 15 October: ask every carrier whose contract renews in Q4 to state in writing which index, base price, reference date, revision frequency and threshold the surcharge formula uses. Then decide whether to accept the formula or renegotiate.
- Fleet management, within 3 weeks: ask your fuel supplier or fuel card provider for Q1 2027 quotes in three variants: a fixed price for part of the volume, phased fixing, and an index with a cap. Request price validity and surcharges. Choose only after comparison; the market may be at a peak.
- Chemicals/agrifood category managers, at the next tender round: ask your CIF suppliers to state the freight component separately and confirm whether freight revision clauses apply. Then compare CIF with FOB.
- Contract management, within 30 days: identify which contracts allow interim surcharges outside the formula. Have legal review hardship and indexation clauses.
