Global Supply Chains on Edge: Ukraine’s Export Freeze

ArcelorMittal Kryvyi Rih cannot safely restart its Ukrainian steelworks after four missile strikes in five weeks, and the company expects a $1 billion impairment.^[1] The shutdown is part of a wider interruption: Zaporizhstal has halted production, five Metinvest furnaces and two at ArcelorMittal have been reported destroyed, and merchant vessels have stopped loading in Ukrainian ports.^{[2, 3, 4]}

Ukraine is losing capacity to make export goods at the same time that the routes needed to sell them are under attack. The grain figures expose the problem. The country expected a harvest of about 60 million tonnes, roughly unchanged from 2025, but grain exports fell 75% in the first two weeks of August compared with a year earlier. The 2026/27 export forecast was cut 12%, from 43 million tonnes to 38–40 million.^[4] About 90% of agricultural exports normally pass through Black Sea ports; cargo ships did not enter those ports for more than three weeks, and shipping sources reported that no merchant vessels had loaded after the attacks intensified.^[4] The reduced forecast therefore reflects constraints on moving the crop, not a comparable decline in the expected harvest.^[4]

Alternative routes cannot absorb the lost maritime capacity at the same scale. The Hungarian corridor is congested, Danube exports face low water levels, routes through Poland are exposed to tensions with local farmers, and the discounted Moldovan rail route can carry only about 10% of exports. Ukraine has also lost an estimated 30% of its railway capacity.^[4] Ukrainian Railways reported 192 locomotives damaged in the first half of 2026, compared with 217 during the entire period from 2022 through the end of 2025; by September, more than 500 locomotives, 1,700 freight cars and 300 passenger cars had been damaged.^{[5, 6]} The preliminary estimate for restoring damaged railway infrastructure is approximately ₴91 billion.^[7]

Even when a ship can sail, the cost of using the Black Sea has risen sharply. Insurance for a voyage to Black Sea ports reached approximately $2.5 million in October, 10–16 times the pre-blockade level of $150,000–250,000. The war-risk component adds approximately $35.70 to the freight cost of each tonne of grain.^[8] This is a direct additional export expense, before any wider losses from delayed or cancelled shipments are counted.

The steel shutdowns make the industrial exposure unusually concrete. ArcelorMittal reported that four missile strikes over five weeks caused extensive damage at Kryvyi Rih; the attacks killed five people and injured 17 employees, and the company said it could not safely restart operations.^[1] It expects a $1 billion impairment, an anticipated accounting charge rather than a confirmed recognized loss.^[1] At Zaporizhstal, damage to energy, logistics and blast-furnace facilities led to a complete halt in operations; one blast furnace was restarted after an attack, only for the site to be hit again hours later.^{[3, 9, 10]} Metinvest has reported five destroyed furnaces across its enterprises, while its Ukrainian facilities continue to face security, labor, electricity and logistics constraints.^{[2, 11]}

The national financial consequence is harder to measure than the company-level damage. A lower grain-export forecast, interrupted steel production and higher shipping costs establish a serious reduction in export capacity, but tonnage forecasts are not realized foreign-exchange receipts. ArcelorMittal's expected impairment does not measure Ukraine's aggregate export losses, and the ₴91 billion railway figure is a preliminary restoration estimate, not money already spent. The energy sector entered this period with a substantial existing burden: by the end of 2025, reconstruction needs were estimated at $91 billion, about half of generation capacity had been destroyed or disabled, and total energy supply was almost 40% lower.^[12] That figure describes the accumulated energy-reconstruction requirement, not the incremental cost of the latest attacks.

The consequences extend beyond the immediate loss of output: exporters have fewer goods they can move to market, higher freight and insurance costs erode margins, and damage to rail and energy infrastructure adds to the reconstruction burden. If sustained, weaker export receipts would also reduce the foreign currency available to pay for imports and other external obligations. The additional loss of export receipts and external financing requirement attributable specifically to the latest attacks has not been quantified.

There is evidence that the campaign is intended to impose economic costs. John Lough of the New Eurasian Strategies Centre described the Russian air campaign as directed at destroying Ukraine's economy, while ACLED researcher Cristian Vlas characterized the attacks as systematic.^[13] But the reported industrial and export disruption does not itself establish that Kyiv has changed its negotiating position, government decisions or ability to sustain the war. The United States is due to mediate fresh peace talks this week as Russian attacks continue to escalate.^[13] Whether the economic pressure changes Ukraine's decisions is a separate test from whether the damage is real.

Ukraine's record on energy recovery argues against treating infrastructure destruction as permanent incapacity. Russian strikes reduced effective electricity-generation capacity by approximately 61% by late 2023, from 36.0 GW to 13.9 GW, disabling 80% of thermal plants, 90% of wind facilities and 44% of nuclear capacity.^[14] Yet Ukraine exported 635.1 GWh of electricity in September 2025 and had been a net exporter for four consecutive months.^[15] By July 2026, it had installed approximately 1.8 GW of distributed gas-fired generation, although reliance on electricity imports increased again during much of October and the east-west grid connection risked failing to deliver power to deficit regions near the front.^{[16, 17, 18]}

Metinvest's production figures provide a second qualification. The group increased first-half 2026 steel output by 13% year-on-year to 1.026 million tonnes; second-quarter production rose 26% from the previous quarter to 572,000 tonnes, partly because electricity supply had stabilized from March.^[11] However, the comparison benefited from a low 2025 base, some growth in finished steel came from operations in Bulgaria and Romania, and Ukrainian facilities remained constrained.^[11] These figures demonstrate that production can recover when electricity is available; they do not reverse the subsequent shutdowns at Kryvyi Rih and Zaporizhzhia or restore blocked export routes.

The European Union may absorb part of the public-finance consequences. It has developed the capacity to mobilize large concessional loans and taken a leading role in supporting Ukraine's public finances.^[19] That financing can help the state meet its obligations, but it does not reopen a steel furnace, replace damaged rolling stock or make Black Sea shipping commercially viable. The additional external financing requirement caused specifically by the latest attacks has not been quantified.

The next operational tests are whether ArcelorMittal Kryvyi Rih can restart, whether domestic steel output recovers across the major plants, whether merchant loading resumes in Black Sea ports, and whether winter electricity imports and outages increase.^{[1, 2, 3, 4, 9, 10, 11, 16, 17, 20]} The 2026/27 grain season will show whether exports remain near the revised 38–40 million-tonne forecast or recover toward the earlier expectation of 43 million tonnes.^[4] Subsequent company disclosures and export-receipt data will determine whether the physical disruption becomes a measurable financial loss; a change in Kyiv's decisions would be needed to establish Russian negotiating leverage.

For now, the clearest company-level exposure is at ArcelorMittal Kryvyi Rih: a plant it cannot safely restart and a $1 billion impairment it expects to record. Ukraine's wider national cost is distributed across grain exporters, steel producers and Ukrainian Railways, whose preliminary restoration requirement has reached ₴91 billion.
