Ce qu’a été cette campagne
A declared blockade of Mali's fuel-import corridors, prosecuted by burning tanker convoys rather than by taking ground. Declared in September 2025, eased in early 2026 and reimposed on 28 April. Neither broken nor decisive: convoys still move, escorted and costlier.
This campaign changed what the war is about. For a decade the question was who holds which towns; the blockade made the question whether the state can keep its economy running. It reaches every household in Mali, it is cheap to sustain, and it cannot be answered by the drone-and-column approach that retook Kidal in 2023 — there is no position to seize. It is also the reason the economic, humanitarian and military pictures in this module converge on one set of roads.

Synthèse
In September 2025 JNIM declared a blockade of fuel imports into Mali and began systematically burning tanker convoys on the routes from Senegal, Côte d'Ivoire and Guinea — the first two reportedly carrying close to 95% of the country's petroleum imports. Over 300 tankers were reported destroyed. Bamako's fuel and power supply degraded visibly through late 2025 — satellite imagery showed the capital darker — and by 2026 convoys moved under escort, at cost and intermittently. The campaign built on an existing westward expansion that had already reached Kayes and the gold belt. It has not run at constant intensity: pressure eased in early 2026, reportedly under a combination of negotiation and heightened military activity, and a full blockade of Bamako was reimposed on 28 April, three days into the northern offensive. In July 2026 it was accompanied by sabotage affecting the capital's water and power. It is the clearest demonstration in this module that attack reach, applied to the right target, produces national effects without territorial gain — and, in the escorted convoys that keep arriving, that such a campaign degrades and taxes a supply line rather than severing it.
Objectifs déclarés
Ce que disent les participants. Chaque entrée cite où la position a été exprimée ; Vigil consigne qu’elle a été exprimée, non qu’elle est vraie.
JNIM publicly declared a blockade on fuel imports, framing it as pressure on the transitional authorities rather than on the population.
Recorded as the organisation's stated position. Vigil does not treat an armed group's characterisation of whom its campaign harms as established.
Objectifs évalués
La lecture de Vigil, assortie d’un degré de confiance. Tenue structurellement à l’écart des positions déclarées, afin qu’une évaluation ne puisse jamais être publiée comme l’objectif déclaré de quelqu’un.
Coerce the transitional authorities by degrading the economy the state's legitimacy rests on, at a cost the organisation can sustain indefinitely.
Demonstrate reach into the west and south — the gold belt and the capital's approaches — establishing that no part of the country is structurally out of range.
Extract revenue and leverage from the movement of goods where the organisation dominates rural areas, of which interdiction is the coercive end.
Taxation of trade is reported by UN panel work; its scale and its relationship to the blockade specifically are not well established.

Forces adverses
- Forces de défense et de sécurité maliennes (FDS) Force adverse · Confiance : élevée · au 2026-07
Convoy escort and corridor security are the state's principal response; both commit forces that are simultaneously needed in the north and centre.
Soutiens et acteurs extérieurs
- Africa Corps — rôle au Mali Force d’appui · Confiance : modérée · au 2026-07
Documented in joint operations with the FDS through the 2026 fighting. Its specific role in corridor security is less well reported than its role in the northern and central hubs.
Westward expansion
JNIM activity extended into western and southern Mali, reaching Kayes and the gold belt, and establishing the presence along the Dakar corridor that the blockade would later exploit. The campaign against the corridors did not begin from nothing: the geography was prepared first.
The Kayes–Nioro blockade
A blockade of the Kayes–Nioro axis in the far west, running through the summer of 2025 and producing acute fuel shortages, a slowdown in the gold sector, school closures and embassy evacuations. It is recorded as its own phase because it is a DIFFERENT EVENT from the national blockade declared that September: a regional interdiction with local effects, on one axis, months earlier. Conflating the two would date the national campaign three months too early and would lose what the earlier episode actually demonstrated — that the corridor instrument worked at regional scale before it was turned on the country.
Declared national blockade
A declared blockade of fuel imports and the systematic burning of tanker convoys, announced on 3 September 2025 after the authorities banned jerrycan fuel sales in several localities. Over 300 tankers reported destroyed across the campaign; Bamako visibly darker by late 2025; convoys shifted to escorted movement from late October.
Easing
Pressure on the corridors eased, reported as the product of negotiation and heightened military activity. The phase matters because it is the only evidence in the record that the blockade is negotiable at all — and because it establishes that intensity, not the existence of a declaration, is what this campaign varies. What was agreed, by whom, and what was given in exchange is not established.
Reimposition and compounded pressure
JNIM reimposed a full blockade of Bamako on 28 April 2026, three days into the northern offensive, and the economic and military campaigns then ran together rather than sequentially: reported checkpoints on Bamako's approaches, attacks reaching Kéniéroba and Kati, and July sabotage affecting the capital's water and power. Reporting indicates the campaign also extended to the eastern supply route from Niger.
Issue et situation actuelle
Ongoing and unresolved. The state has neither broken the blockade nor collapsed under it: convoys still move, at higher cost and lower frequency, under escort arrangements that commit forces needed elsewhere. Fuel and power in the capital remain degraded relative to 2024, and the campaign has not been reversed by any military action. Whether it tightens or eases is one of the module's standing watch items.
Adaptations observées
A shift from attacking military targets to attacking the movement of commercial goods — an economic-warfare approach that requires no territorial holding and cannot be answered by recapturing ground.
Interdiction along the length of the corridors rather than only at their ends: attacks in the Kita cercle during the 2025 western offensive indicated the campaign targets corridor infrastructure wherever it is thinnest.
State adaptation to escorted convoy movement, which sustains supply at materially higher cost and commits forces to route security. The army is reported to have escorted more than a thousand tankers into Bamako since late October 2025 — the measure of the adaptation's partial success, and the reason this campaign is better described as taxing the corridor than as closing it.
Variable intensity rather than continuous interdiction: the campaign eased in early 2026 and was reimposed in full on 28 April, timed to the northern offensive. Whether that reflects a deliberate tempo, a negotiated pause or a period of degraded capability is not established.
Implications politiques
Shortage in the capital is the pressure point nearest the transitional authorities' own political base, and the one least answerable by a battlefield success.
Implications militaires
Route security competes for forces with the northern and central fronts, and the army's own logistics burn the same imported fuel.
Implications économiques
Transport-cost inflation transmits to food prices, trade volumes and customs revenue simultaneously; the gold sector's exposure is the state's fiscal concern.
Implications humanitaires
Market supply and relief movement depend on the same corridors, so price rises and access constraints compound rather than merely coincide.

Ce qui reste inconnu
- Reported tanker destruction totals rest on official statements, armed-group claims and media reporting with no independently audited count. They should be read as orders of magnitude.
- The terms of the early-2026 easing are not established: who negotiated, what was offered, and whether the reduction in attacks was a concession or a consequence of military pressure are all reported rather than documented. This record grades that phase at low confidence for that reason.
- The organisation's internal decision-making and the campaign's cost to it are not observable; the assessment that it is cheap to sustain is an inference from its continuation, not a measurement.
- The extent of coordination between the blockade and the April–July 2026 offensives is not established. Simultaneity is documented; a single plan is not.
Lectures que les éléments permettent aussi
- The blockade can be read as an economic-coercion strategy aimed at the government, or as the coercive edge of an existing rural taxation system extended to the main corridors. The two are not mutually exclusive, and the reporting does not decisively separate them.
- Fuel scarcity in this period also reflects regional freight costs and the loss of ECOWAS free movement after the January 2025 exit. The blockade is the dominant reported driver, not the only one.
