Supply chain activity in the U.S. remains below its long-run average as the market searches for a clear direction, according to a report from trailer rental provider Warehouse on Wheels. That conclusion comes from the Fort Mitchell, Kentucky-based firm’s WOW Supply Chain Activity Index, a monthly measure that serves as an indicator of U.S. logistics and warehousing activity. Each month, the report produces an index number drawn from nine inputs: WOW Deployment Ratio, LMI Warehousing Utilization, LMI Transportation Prices, Cass Freight Index, ISM Manufacturing PMI, ISM Supplier Deliveries, Mfrs. Inventories-to-Sales Ratio, NY Fed Global Supply Chain Pressure, and U.S. Industrial Vacancy Rate. In WOW’s analysis, that figure means that June was in the Contraction zone, defined as any value below 45.
