**Summary**: Ukrainian diplomats told Greek officials that Kyiv will continue striking Russian tankers in international waters, framing the attacks as self-defense under the UN Charter. This formal political signal hardens expectations that the recent Azov/Black Sea ‘shadow fleet’ campaign will persist or expand, lifting risk premia across crude, product tanker routes, and Black Sea grain flows.

## Detail

1) What happened:
A new diplomatic report states that Ukrainian officials have explicitly informed Greek counterparts that Ukraine will continue targeting Russian tankers in international waters, citing self-defense under Article 51 of the UN Charter. This is not just a battlefield update but a clear policy articulation to a key maritime/shipping stakeholder state, signaling intent to maintain – and potentially broaden – recent attacks on Russia’s “shadow fleet” used for oil and product exports.

2) Supply/demand impact:
The direct physical loss of barrels remains uncertain, but the key effect is a sharp increase in operational and legal risk for vessels moving Russian crude and products, especially older, underinsured tankers. Higher insurance premia, rerouting, and self-sanctioning behavior by owners and service providers can effectively tighten available shipping capacity for Russian exports by several percentage points even without formal sanctions changes. If owners begin refusing certain routes or flags, effective Russian seaborne supply could be curtailed by hundreds of thousands of barrels per day in periods of heightened attacks. Additionally, any spillover of attacks from Azov/Black Sea into wider international waters would raise perceived risk on broader tanker trades, including non-Russian cargoes transiting contested regions.

3) Affected assets and direction:
Crude benchmarks (Brent, Urals differential, Dubai) should see higher risk premia, with upward pressure on Brent and on Mediterranean grades in particular. Freight rates for Aframax/Suezmax tankers in Black Sea/Med, and insurance premia for ships linked to Russian trade, are likely to firm. Russian export-linked cracks in products (fuel oil, VGO, naphtha, diesel) may widen on logistics friction. Black Sea grain and vegoil flows may also see secondary risk repricing due to greater perceived combat reach in regional waters.

4) Historical precedent:
Similar patterns were seen during the 2019–2021 Gulf tanker attacks, and the early months of the 2022 Black Sea war disruption, where elevated perceived maritime risk added several dollars per barrel to Brent despite limited outright loss of supply.

5) Duration:
This is structural as long as the war continues and Kyiv maintains this doctrine. Expect intermittent volatility spikes around each new incident, with a persistent elevated risk premium embedded in regional oil and freight markets rather than a one-off shock.

**AFFECTED ASSETS:** Brent Crude, Urals crude differentials, Mediterranean crude spreads, Product tanker freight rates (Black Sea/Med), Marine war risk insurance premia, Black Sea wheat futures, EU gasoil futures
