The Complete SONAR Sitrep Library: Every Freight Market Intelligence Briefing Published in 2026
A SONAR Sitrep is a freight market intelligence briefing produced by the FreightWaves SONAR team. Each Sitrep combines live SONAR index data with rail, ocean, regulatory, and macroeconomic sources to explain a single structural shift in freight demand, capacity, or pricing — the kind of signal that shows up in the data weeks before it shows up in headlines.
As of July 23, 2026, SONAR has published more than 30 Sitreps covering everything from Supreme Court rulings on broker liability to coal rail traffic to the AI data center buildout. Below is the full library in one place, with a one-line summary of what each one covers.
