Black Sea — strategic chokepoint

Why this basin matters for trade, energy and security.

What’s the point?

The Black Sea links grain markets, energy assets and shipping lanes of Europe, Asia and MENA. Before the war, Russia and Ukraine jointly accounted for about 34% of global wheat exports, 17% of corn and ~75% of sunflower oil (FAO). Shocks to shipping and insurance pass quickly into food prices.

Trade & food

In 2022–2023 the Black Sea Grain Initiative enabled exports of about 32.9 million tons (mostly corn and wheat), cooling price pressure.

  • Price channel: reopening the sea route reduced risk premia and eased access for MENA/EU importers.
  • Logistics: short route: UA ports → Bosporus → Med → MENA/EU ports.
  • Insurance: when tensions rise, war-risk premia and banking requirements go up.

Energy

The region hosts energy infrastructure: Turkish fuel/LNG terminals and gas pipelines from Russia to TR/EU. TurkStream capacity is 31.5 bcm/year (~half for TR, half to the EU via BG–RS–HU). With EU gas demand of ~326–330 bcm in 2023, this is a low single-digit share, yet strategically important for transit states and local consumers.

  • Flows & policy: the Montreux Convention governs straits traffic; incidents raise risk.
  • Substitution: TR routes and LNG reduce exposure to other corridors.

Practical effects

  • Food prices: sea access ↓ → indices eased; disruptions → spikes.
  • Freight & insurance: NAVTEX/NOTAM & incidents lift war-risk and freight rates.
  • Risk transfer: shipowners/banks/insurers pass premia into final prices.

Pros / opportunities

  • More capacity & predictability → steadier prices, lower risk premia.
  • Logistics diversification (TR, LNG, alternates) → less exposure to chokepoints.
  • Better credit/insurance coordination → easier supply-chain finance.

Cons / risks

  • Step-ups in war-risk & freight after incidents; possible port stoppages.
  • Escalation may curb grain availability again → food basket inflation.
  • Strait bottlenecks (Bosporus/Dardanelles) → queues and delays.
