JNIM fuel blockade campaign
An insurgency strangling a state's economy without taking a city — declared September 2025 and still running.
A declared blockade of Mali's three fuel-import corridors, running since September 2025 and prosecuted by burning tanker convoys rather than by taking ground. It turned the war into a question of whether the state can keep its economy running. Neither broken nor decisive: convoys still move, escorted and costlier.
Summary
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. Several hundred 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, and in July 2026 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.
Why it matters
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.
Stated objectives
What the participants say. Each entry cites where the position was stated; Vigil records that it was made, not that it is true.
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.
Assessed objectives
Vigil's reading, graded. Kept structurally apart from stated positions so an assessment can never be published as someone's declared aim.
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.
Primary forces
- JNIM — Group for the Support of Islam and Muslims Primary force · Confidence: High · as of 2026-07
Opposing forces
- Malian Defence and Security Forces (FDS) Opposing force · Confidence: High · as of 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.
Supporting & external
- Africa Corps — Mali role Supporting force · Confidence: Moderate · as of 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.
Phases
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.
Declared blockade
A declared blockade of fuel imports and the systematic burning of tanker convoys. Several hundred tankers reported destroyed; Bamako visibly darker by late 2025; convoys shifted to escorted movement.
Compounded pressure
The blockade continued alongside the northern and central offensives, with reported checkpoints on Bamako's approaches, attacks reaching Kéniéroba and Kati, and July sabotage affecting the capital's water and power. Economic and military pressure were applied together rather than sequentially.
Outcome and present status
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.
Observed adaptations
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.
Political implications
Shortage in the capital is the pressure point nearest the transitional authorities' own political base, and the one least answerable by a battlefield success.
Military implications
Route security competes for forces with the northern and central fronts, and the army's own logistics burn the same imported fuel.
Economic implications
Transport-cost inflation transmits to food prices, trade volumes and customs revenue simultaneously; the gold sector's exposure is the state's fiscal concern.
Humanitarian implications
Market supply and relief movement depend on the same corridors, so price rises and access constraints compound rather than merely coincide.

Reference layers
What remains unknown
- 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 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.
Readings the evidence also supports
- 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.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
What to watch
Does the blockade tighten or ease?
Fuel and food availability in Bamako, Ségou and Kayes, and tanker convoy losses on the Dakar and Abidjan corridors.
Does pressure on the gold belt become sustained?
Whether the western campaign moves from corridor attacks to sustained pressure on mining areas. The state's fiscal base has no substitute.
Does attack reach near Bamako become durable?
Kéniéroba and Kati are within the capital region. Whether that becomes something more than raiding is the campaign's most consequential open question.
