RUC NRG 40% of Russia's Oil Export Capacity Offline — Worst Disruption in Modern Russian History

Reuters 25 Mar · Moscow Times 25 Mar · Kyiv Independent 25 Mar

Reuters calculates that roughly 2 million barrels per day of Russian crude export capacity — approximately 40% of total — is now offline. The disruption combines three vectors: Ukrainian drone strikes on all three major western export ports (Primorsk and Ust-Luga on the Baltic, Novorossiysk on the Black Sea), the continuing Druzhba pipeline shutdown since January, and European seizures of shadow-fleet tankers disrupting around 300,000 bpd of Arctic exports from Murmansk.

Overnight on 25–26 March, Ukrainian drones struck the Kirishi refinery in Leningrad Oblast for the second consecutive night — the same campaign that sent drone swarms through Estonian maritime airspace and stray munitions into Estonian and Latvian territory on 25 March (Signal No. 24; updated assessment below). Ust-Luga — Russia's largest Baltic oil port — remains suspended. Russia continues uninterrupted pipeline deliveries to China and ESPO Blend seaborne exports via Kozmino, but Asian routes are capacity-constrained. Brent remains above $100. The UK announced on 25 March that the Royal Navy will board Russian shadow-fleet vessels in British territorial waters — PM Starmer framed it as an extension of sanctions enforcement targeting maritime infrastructure that funds Russia's war.

Signal Ukraine's energy-denial campaign has reached a scale that directly affects Russian fiscal capacity. Oil revenues fund roughly a quarter of the Russian state budget. With the Iran conflict simultaneously tightening global supply, Moscow cannot offset lost western export revenues through Asian routes — it lacks the infrastructure. The Druzhba pipeline's continued shutdown is now the lever Orbán is pulling to block the €90 billion Ukraine loan and the 20th sanctions package — a connection explored directly below.

IAMD NATO The Baltic Drone Story Is Bigger Than Yesterday's Lead — Swarms Crossed NATO Airspace, Units Redeployed, and a Dual Engagement Constraint Emerged

Signal No. 24 reported that two drones hit Estonian and Latvian territory during the Ust-Luga attack on 25 March. The Estonian-language press conference and subsequent reporting show the incident was significantly larger. Defence Minister Hanno Pevkur confirmed that "several drones" and "drone swarms" cut Estonia's maritime airspace boundary "multiple times" over the Gulf of Finland during the attack. The Auvere drone was not a surveillance or navigation device — Defence Forces commander General Merilo assessed it as a warhead-carrying attack or decoy drone. Italy's Eurofighters at Ämari were scrambled. A no-fly zone was imposed over eastern Estonia through Friday. The Defence Forces moved units outside their peacetime and permanent locations to conduct identification and, if necessary, defence tasks — an elevated-readiness posture that Estonia's officials were careful to distinguish from mobilisation, stressing the country remains in a peacetime state. Merilo stated explicitly that Estonia will not engage drones near the border: "me kindlasti ei saa mõjutada droone, kus on väiksemgi risk, et meie mõjutustegevus võib kanduda üle Venemaa territooriumile" — "we certainly cannot affect drones where there is even the slightest risk that our engagement activity could carry over onto Russian territory." He separately noted that peacetime law limits available engagement methods, because debris risks falling on Estonian civilians below.

All three Baltic states recorded overlapping drone spillovers within 48 hours, yet their responses diverged. Lithuania reported a stray Ukrainian drone crashing into a lake in Varėna district on 23 March. The drone flew below 300 metres and was not detected by Lithuania's main surveillance radars or border guards. Defence Minister Kaunas confirmed Lithuania has ordered additional low-altitude radar systems, but deliveries are not expected until 2026–2028. No airspace restrictions were imposed. Latvia recorded one drone detonating in Krāslava district and a third entering from Belarus before looping back into Russian airspace. Latvia already maintains partial nighttime airspace restrictions along its eastern borders, in place since October 2025, but did not escalate them. Defence Minister Sprūds, speaking to Latvian Television on 26 March, acknowledged that response capabilities remain "limited" and named interceptor drones as the priority.

This episode followed a Russian Navy Su-30SM violating Estonian airspace on 18 March, prompting the scramble of Italian Eurofighters, and a broader acceleration in Russian pressure on NATO airspace: a February 2026 review counted 18 confirmed Russian airspace violations in 2025, a 200% increase over 2024. Poland requested Article 4 consultations after a September 2025 drone incursion, and Estonia did the same later that month after a MiG-31 airspace violation. The same review recorded at least two further violations by mid-February 2026, before this week's events.

Signal Merilo's two constraints — peacetime law limiting engagement methods, and border geometry precluding action where debris could cross into Russia — interact to create, in effect, an asymmetric dead zone.
Russian EW can push Ukrainian drones off course into NATO airspace, but NATO states along the Russian border cannot shoot them down at the approaches without risk to either their own civilians or of cross-border effects. Moreover, what occurred on 25 March was an entire strike wave that transited or brushed through that zone — not merely a single stray drone.
Estonia's initial response echoes the logic of Poland's 90-day EP R130 low-altitude exclusion zone along the Ukraine and Belarus borders (Signal No. 11), but under fundamentally different conditions. Poland's restriction was a cold response — imposed after a commercial drone crashed at a military base near Leźnica Wielka, with no active strike in progress, on Warsaw's own timeline. Estonia's was declared during a live strike wave, with warhead-carrying drones transiting through airspace where the Russian border is less than 3km away. Poland could plan and structure; Estonia had to react under conditions where engagement decisions carry immediate physical consequences across the border. Signal No. 11 observed that if similar restrictions were replicated across the eastern flank — Baltics, Romania — the cumulative effect would resemble a low-altitude denial corridor from the Arctic to the Black Sea. That remains a conceptual extrapolation. Nothing in this week's responses suggests coordinated movement in that direction. Poland's posture is structural, Latvia's partial and openly acknowledged as insufficient, Estonia's reactive, Lithuania's rather long-term oriented; with radars that could close the gaps still years from delivery.

Policy DIN Commission Freezes Hungary's ~€16 Billion SAFE Allocation — Retaliation for the €90bn Ukraine Loan Veto

Ukrainska Pravda 25 Mar · United24 Media 26 Mar · Al Jazeera 19 Mar · HVG 4 Feb · Kontroll 3 Feb · Telex 25 Mar · Economx 21 Mar

The European Commission approved SAFE defence plans for France and Czechia on 25 March, leaving Hungary as the only one of 19 participating member states whose plan remains frozen. An EU diplomat told Polish outlet RMF24 that the block is linked directly to Budapest's veto of the €90 billion Ukraine loan: "It is difficult for the European Commission to agree to billions of euros for Viktor Orbán when he is violating the principle of loyal cooperation and blocking money for a country that is fighting Russia." Budapest is reportedly seeking over €1 billion more than the Commission is offering and remains "very interested" in receiving SAFE funds.

The linkage has hardened on both sides. On 25 March, Orbán announced Hungary will wind down gas supplies to Ukraine if Druzhba oil transit is not restored — an escalation from his European Council position on 19 March, when he conditioned the €90bn loan, the 20th sanctions package, and broader Ukraine decisions on the pipeline. Finnish PM Orpo and Belgian PM De Wever both publicly suggested the EU may simply wait until after Hungary's 12 April election to move the loan forward.

Hungarian-language reporting reveals a more entangled picture than the external narrative of simple coercion suggests. Economy Minister Nagy Márton personally championed SAFE participation after Fidesz had publicly attacked the programme and parliament had passed a resolution against it — Budapest originally requested over €20 billion, forced down to €16.2 billion by demand from other member states (HVG). More significantly, the government has already pre-committed approximately 297 billion forints of the SAFE allocation — partly to economic development and housing, not defence — before the plan was even approved (Kontroll/Válasz Online). Budget Commissioner Serafin warned in the European Parliament that the same procurement and governance deficiencies that triggered the €17.5 billion rule-of-law freeze on other EU funds apply to SAFE disbursement too (Telex). The result is a mutual trap: Orbán campaigns against Brussels while demanding its largest available credit line, and the Commission cannot easily release defence funds to a government that has pre-spent them on non-defence items and remains under an active conditionality procedure. Domestically, Orbán frames this through the "Nemzeti Petíció" — a door-to-door canvassing campaign with posters depicting von der Leyen, Weber, and Zelenskyy as "demanding our money" (Economx).

Signal The Commission is now using SAFE as a coercive instrument — freezing defence financing to punish a foreign-policy veto on a separate instrument. But the Hungarian-language record shows this is not simply Brussels punishing Budapest; it is a mutual trap. Orbán's government publicly attacked SAFE, then applied for the third-largest allocation; pre-spent a quarter-trillion forints of the allocation on non-defence items before approval; and now campaigns against the programme it needs. The Commission cannot easily release funds because the same rule-of-law problems that froze €17.5 billion in other EU disbursements apply here too. Neither side can back down before 12 April.
