Weaponizing the Larder: How Moscow Uses Grain, Fertiliser, and Ports to Leverage Global Food Security

Weaponizing the Larder: How Moscow Uses Grain, Fertiliser, and Ports to Leverage Global Food Security

Introduction: From Ports to Pantries — The New Front in

Food is a strategic commodity. Beyond humanitarian stakes, grain and fertiliser are instruments of statecraft when concentrated production and chokepoints meet predatory diplomacy. Since the 2022 war in , Moscow has demonstrated a growing willingness to exploit agricultural markets and maritime logistics to advance geopolitical goals: leveraging shipments, manipulating fertiliser supplies, and extracting political concessions from import-dependent countries across the Middle East, Africa and beyond.

The Anatomy of ’s Agricultural Leverage

Russia and Ukraine historically accounted for a large share of global wheat and coarse grain exports. When war disrupted Black Sea corridors, Moscow moved quickly to convert market position and logistical control into leverage.

1. Black Sea Chokepoints and Naval Coercion

The Black Sea is more than a transit route; it is a bargaining chip. By controlling or threatening key maritime approaches and by mining and militarizing sea lanes, Moscow has periodically constrained Ukrainian exports and used the specter of instability to extract concessions from grain buyers and mediators. Parallel to direct coercion, the Kremlin exploits commercial maritime networks and reflagging to reroute shipments, masking true origins and destinations.

2. Fertiliser: The Hidden Backbone of Harvests

Russia — together with Belarus — is a dominant supplier of potash, ammonia and other fertiliser inputs. Fertiliser is bulky, politically sensitive, and harder to substitute quickly than some other commodities. By threatening export curbs, levying informal export taxes, or using private-export channels to favor preferred partners, Moscow can reduce yields abroad next season, creating medium-term leverage that outlasts short shocks to grain shipments.

3. Commercial Networks, Shadow Fleets and Workarounds

As our recent reporting has shown, Russia has adapted to sanctions through reflagging, ship-to-ship transfers and shadow-finance routes. Those same practices sustain grain and fertiliser flows to buyers despite restrictions on bank access or trade finance. Shadow logistics maintain cash flows to Russian exporters while making provenance and payment chains opaque — complicating Western efforts to enforce restrictions or to use restraint as leverage.

Concrete Cases and Data Points

Market influence: Before the war, combined Russian and Ukrainian exports supplied a substantial share of global wheat markets; even with disruptions, Russia expanded market share in many destinations through aggressive discounts, state-backed shipping deals, and supplier lock-ins.

Targeted diplomacy: Moscow has offered concessional grain and fertiliser deals to states where it seeks influence — countries in North Africa, parts of the Middle East, and select sub-Saharan partners. These commercial offers are often bundled with arrangements, energy cooperation, or private deployments, turning food access into a form of political patronage.

Logistics control: Ports, grain terminals and agri-logistics hubs are lucrative targets. Ownership stakes, long-term leases or operational control over terminals let Russian-linked firms influence scheduling, insurance access and port operations — effectively shaping export flows without formal state proclamations.

Strategic Implications for Import-Dependent Regions

The weaponization of food has cascading effects:

  • Political leverage: Receiving countries face difficult trade-offs between immediate food supply and longer-term political independence.
  • Economic volatility: Market manipulation and opaque shipping raise price volatility, disrupting fiscal balances in fragile states.
  • Security risks: Food insecurity heightens the probability of unrest, creating opportunities for external actors — including Russian proxies — to cement influence.

For example, MENA and parts of Africa that rely heavily on Black Sea grain are particularly vulnerable. A delay in fertiliser deliveries in one planting season can translate into diminished harvests and higher import dependence the following year, deepening strategic reliance on suppliers willing to tie shipments to political outcomes.

How Moscow Converts Commercial Tools into Political Gains

Russia’s playbook is layered and adaptive:

  1. Price and contract engineering: Discounts, forward contracts tied to diplomatic conditions, and barter arrangements (grain for military equipment, fishing rights, or logistics access).
  2. Targeted infrastructure control: Acquiring or operating terminals and warehouses that determine who gets priority access in congested periods.
  3. Logistics shadowing: Using reflagged vessels and intermediaries to keep flows open to selected partners even under sanctions.
  4. Economic coercion: Threatening export curbs or sudden regulatory interventions to pressure governments into negotiations on unrelated political objectives.

Policy Responses: How the West Can Disrupt the Leverage

Mitigating food-weaponization requires a blend of short-term crisis management and structural resilience measures:

1. Transparency and Supply-Chain Tracking

Invest in satellite, AIS, trade data and port-record transparency to trace shipments and identify shadow-routing and reflagging. Public, near-real-time monitoring reduces Moscow’s ability to conceal origins and destinations.

2. Targeted Financial and Trade Tools

Sanctions and export controls should be calibrated to avoid exacerbating shortages while denying long-term rent to exploitative actors. That can include targeted measures on fertiliser intermediaries that enable evasion and sanctions on firms fronting for state-directed export-bundles tied to political concessions.

3. Build Importing-Country Resilience

Support strategic grain and fertiliser reserves in vulnerable states, subsidize diversification of suppliers, and finance modern storage and logistics to reduce single-source dependence. International donors should prioritize agricultural inputs in aid packages to break short-term political linkages.

4. Secure Ports and Insurance Markets

Coordinate Western engagement in Black Sea and Mediterranean port governance, enhance underwriting standards to penalize opaque transfers, and collaborate with allied registries and insurers to deny cover to sanctioned shadow fleets when used for political coercion.

Risks and Limitations of Western Responses

Policy responses are imperfect. Overly broad sanctions can squeeze legitimate markets and harm consumers in vulnerable countries. Transparency measures can be circumvented by more sophisticated intermediaries. And attempts to directly supplant Russian supplies with Western alternatives risk creating new dependencies if not paired with durable market instruments and capacity-building.

Conclusion: A Strategic Priority for Western Policy

Russia’s exploitation of the agri-food complex represents a material escalation in the use of economic instruments for geopolitical ends. Unlike many other sectors, food and fertiliser directly affect domestic stability in importing states — making them potent leverage points. Western policymakers must recognize that countering this requires more than ad hoc humanitarian relief: it demands an integrated strategy combining market monitoring, targeted financial measures, resilience-building in importing states, and pressure on the logistics networks that make political grain diplomacy possible.

Failing to act will leave vulnerable populations hostage to commercial coercion—and give Moscow a quiet, persistent tool to reshape influence across Africa, the MENA region and beyond.

Recommended next steps for policymakers:

  • Fund a public-private grain and fertiliser-tracking platform to monitor real-time flows.
  • Target sanctions at shipping and trading intermediaries that facilitate political export bundling.
  • Provide short-term fertiliser and seed packages to high-risk importers paired with reforms to diversify procurement.

Only by treating food as a strategic domain can the West blunt Moscow’s ability to weaponize pantries and preserve stability in the most vulnerable regions of the world.
