Deepwater Horizon oil spill Gulf of Mexico fishery closures (2010-2011)
2010–2011: a documented market event that overlapped the wholesale price windows of 4 tracked ingredients — co-occurrence in time, never an asserted cause.
What happened
After the April 20, 2010 Deepwater Horizon blowout in the Gulf of Mexico, NOAA began closing federal Gulf waters to commercial and recreational fishing on May 2, 2010; at its peak around June 21, 2010 the closure covered about 37% of the federal Gulf (roughly 229,000 square kilometers / 88,522 square miles). Waters were reopened in stages after seafood sampling and testing, with all federal Gulf waters reopened to fishing by April 19, 2011. Shrimp and Gulf blue crab were among the fisheries documented within the closed area.

Affected ingredients
- Shrimp
- Shrimp Head On
- Shrimp Pd
- Crab
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.
- ShrimpWild vs imported US wild landings were $312M (2024), beside $1.62B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
- Shrimp (head-on)Wild vs imported US wild landings were $312M (2024), beside $1.62B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
- Shrimp (P&D)Wild vs imported US wild landings were $312M (2024), beside $3.32B of imports — two different measures, not a supply share. Most imports of this species are farmed abroad.
- Crab (whole)Wild vs imported US wild landings were $694M (2024), beside $1.55B of imports — two different measures, not a supply share.
Wild landings and imports are two different measures, not a supply share. 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.
