How does ASTVI differ from traditional tender acceptance rate indices?

ASTVI directly measures the volume of freight that was accepted and moved, rather than simply tracking the percentage of loads rejected. By isolating accepted volume, it eliminates the need to manually calculate backwards from rejection data, providing a cleaner, more intuitive picture of actual freight flowing through the market. This distinction is particularly valuable in soft markets where rejection rates are elevated.

What data granularity is available in the ASTVI?

ASTVI is available at national, regional, and market levels. It covers total accepted volume plus dedicated segments for van and reefer freight. Users can access week-over-week, month-over-month, and year-over-year change metrics for each category, enabling multi-timeframe trend analysis.

Why is the gap between tendered and accepted freight meaningful for supply chain professionals?

When market conditions soften, routing guide compliance deteriorates and carriers become more selective, widening the spread between offered and accepted loads. ASTVI directly quantifies this spread without requiring manual backcalculation. This helps brokers reset expectations, carriers understand selectivity trends, and shippers adjust demand planning.

Who benefits most from ASTVI data?

The primary beneficiaries are brokers, carriers, shippers, and freight market analysts. Brokers use it to understand carrier selectivity; carriers track competitive volume and market direction; shippers optimize tendering strategies; and analysts gain cleaner market perspective for reporting and forecasting.

How frequently is ASTVI data updated?

ASTVI updates daily, enabling users to track real-time shifts in accepted volume trends across national, regional, and market levels. This frequency supports rapid decision-making and responsive strategy adjustments.

The signal

SONAR has introduced the Accepted SONAR Truckload Volume Index (ASTVI), a new market intelligence tool that distinguishes between tendered freight and freight that actually moves through the market. This fills a critical analytics gap, particularly during soft market conditions when rejection rates spike and routing guide compliance weakens. The index tracks accepted volume at national, regional, and market levels, covers van and reefer segments, and updates daily with multiple time-horizon comparisons. For supply chain professionals, ASTVI reduces the manual effort required to understand true market dynamics.

Previously, analysts had to cross-reference multiple indices and back into accepted volume by subtracting rejections from tenders. The new index provides direct visibility into the friction between offered and accepted loads—a key indicator of carrier selectivity and market balance. This is especially valuable during periods of soft demand when brokers face higher rejection rates and need accurate data to reset expectations. The launch reflects broader industry recognition that tender acceptance rates alone are insufficient metrics.

By isolating accepted volume, SONAR enables brokers, carriers, shippers, and analysts to make data-driven decisions about pricing, capacity allocation, and market positioning. Access is available to SONAR subscribers through a pre-made dashboard, with full documentation provided.
