Sources indicated on 18 October 2026 that shipbroker Gibson has warned a sudden boost of tanker supply could follow if the United States adopts a waiver permitting sanctioned tankers to re-enter mainstream trade.
The report noted that the waiver under consideration would allow vessels previously sanctioned for links to Russia, Iran or Venezuela either to carry non‑sanctioned oil or to be sold to conventional owners. Gibson described the measure as under active consideration by US authorities in its latest weekly note, a development the Hellenic item framed as potentially reshaping available tonnage.
If implemented the measure would be conditional and limited in scope, according to the reporting; the suggestion in the Hellenic item was that a sizeable tranche of the tanker fleet might be affected. That possibility is the subject of the headline question which asks whether as much as 15 per cent of the tanker fleet could effectively receive a "clean slate".
What the waiver would change
Permitting previously sanctioned vessels to carry non‑sanctioned crude or to be transferred into mainstream ownership would alter the pool of commercially available tankers. The Hellenic summary of Gibson's note presented this as a shift from exclusion towards conditional re‑entry, rather than an unconditional removal of restrictions.
Any change of status for sanctioned tonnage would be focused on the vessels themselves and their permitted trading pattern rather than on the underlying political disputes that led to sanctions. The Hellenic report made clear that the waiver under discussion is specifically about operational permissions and transfers of ownership, as described by Gibson.
Market and supply implications
A rapid increase in available tankers would, in market terms, represent additional supply in the freight market and could relieve strains caused by tight tonnage. Hellenic's coverage portrayed Gibson's assessment as indicating that an immediate and noticeable effect on the tanker pool is possible if the waiver proceeds.
The report gave no definitive estimate for timing or the precise number of ships that would be covered, and Gibson's public comment as summarised by Hellenic was presented as a conditional scenario rather than a forecast. The piece underlined that the measure remains a matter for US policy decision, not an already enacted rule.
Next steps and points of caution
Any waiver would require formal adoption and clear implementing guidance before market participants could act on it, the Hellenic summary suggested. Until such guidance appears, owners, brokers and charterers would be expected to treat the matter as a potential future change rather than settled policy.
The reports item identified the prospect as newsworthy because of the implications for vessels once subject to sanctions for links to Russia, Iran or Venezuela. Gibson's weekly report was the source of the assessment reproduced in the coverage.
The wider commercial and legal context that surrounds sanctioned tonnage was not expanded on in the Hellenic synopsis beyond the description of the waiver under consideration. Readers seeking the full text of Gibson's note or the Hellenic item should consult those original publications for detail and any subsequent developments.
In summary, reports's 18 October 2026 report, citing Gibson, set out a single proposition: a United States waiver under deliberation could permit a group of tankers currently under sanctions to carry non‑sanctioned oil or be transferred into mainstream ownership, an outcome that might amount to a substantive increase in available tanker supply and that has been framed in the coverage as potentially affecting roughly 15 per cent of the fleet.
