Russia-Ukraine war: Black Sea grain & sunflower-oil disruption (2022)
Feb 2022: a documented market event that overlapped the wholesale price windows of 1 tracked ingredient — co-occurrence in time, never an asserted cause.
What happened
Following Russia's invasion of Ukraine on February 24, 2022, USDA FAS and FAO documented major disruption to Black Sea grain and oilseed shipments. Ukraine, which moved more than 90% of its agricultural exports by sea and supplied roughly 47% of world sunflower-oil exports in 2021, saw exports fall sharply as its ports were blockaded early in the war; monthly Ukrainian agricultural exports dropped to about 1.2 million metric tons before the UN-brokered Black Sea Grain Initiative (July 2022) allowed volumes to recover toward roughly 6.3 MMT per month by December 2022. Ukraine and the Russian Federation together are among the world's leading exporters of wheat, maize and sunflower oil.

Affected ingredients
- Vegetable oil
Why these ingredients were exposed
Each affected ingredient's public supply structure — where it comes from and how much it leans on imports. Context that makes the co-occurrence with a documented event legible, never its cause.
- Vegetable oilDomestically sourced comes almost entirely from domestic production, with little import buffer. Its exposure runs through domestic production structure, not import origins — a domestic event overlaps its price window.
It explains why an ingredient sits in the path of a documented event — not that the event caused any price move. Co-occurrence in time, never a cause.
The detected moves that overlapped
Each figure is a wholesale reference against its own ±26-week normal — a market move, never a delivered price.
No sustained wholesale move in our detected set falls inside this event's window. The event is documented; our public price series simply didn't flag a notable departure from normal for these ingredients then — an honest absence, not a hidden one.
What moved together
Co-occurrence, not cause
Vegetable oil
In Vegetable oil's 6 notable moves, these ingredients ran the same direction in the same weeks:
Moving in the same weeks is not one thing causing another — many of these share a growing region, a shipping lane, or an aisle. It is a directed, bounded count: in K of an ingredient's own notable moves, another ran the same way.
