The June 30 USDA Acreage and Grain Stocks reports fall inside the 5-day window and are a known volatility catalyst; they likely added bearish supply sentiment that spilled over from corn and soybeans into wheat alongside the ongoing winter wheat harvest pressure, though the reports alone probably do not account for the full 13% decline.

The USDA Acreage and Grain Stocks report on 2023-06-30 is a major volatility event that could reset supply expectations and spark follow-through selling on the next trading session (July 3), but the summary gives no details on the actual surprise, and a -5.58% move is large enough that other factors (e.g., Black Sea/export developments) may also be contributing, so the link is plausible but unconfirmed.
