The 2026 crop year offered the first major stress test of the Margin Coverage Option (MCO), a new area-based insurance endorsement designed to protect county-level operating margins from lower crop revenue, higher input costs, or both. This brief examines how the 2026 Strait of Hormuz disruption affected expected MCO-95 outcomes for corn and soybeans. The disruption sharply increased fertilizer and energy costs during MCO’s April harvest input price discovery period, while crop prices provided little offset. Using simulated county-level yields, market conditions as of June 11, 2026, and RMA policy data, we estimate that MCO-95 trigger probabilities averaged about 68 percent for corn and 61 percent for soybeans. Expected net returns were also positive, averaging approximately $35.60 per acre for corn and $22.10 for soybeans. Results suggest that MCO provided meaningful cost-risk protection in 2026, although final payments remain conditional on harvest prices and county yields.
