Oil Market Reactions to Maritime Chokepoint Disruptions

Replication package and accompanying report for a descriptive event-study comparison of daily Brent and WTI futures-proxy reactions to the 2021 Suez Canal blockage and the acute phase of the 2026 Strait of Hormuz crisis. The package contains the RMarkdown source, archived analytical snapshot, processed returns, event definitions, benchmark distributions, tables, figures, a self-contained HTML report, a print-ready PDF, exact R package versions, and software-session metadata. Event-day returns are the primary horizon; [-1,+1] and [0,+3] trading-day windows are timing sensitivities. Results are descriptive associations, not causal estimates.
