The supply chain "bullwhip effect" is both predictable and expected. The surge of inventories and declining freight costs/capacity imbalances will be deflationary.

The trucking market has slowed. Demand for trucks usually surges during the Spring, but this year, demand for truckload freight has broken out of this typical seasonal pattern.

The bullwhip effect is something every supply chain 101 student learns about – the idea that upstream providers overproduce in reaction to a one-time demand shock.

According to the Chartered Institute of Procurement and Supply, the bullwhip effect "is defined as the demand distortion that travels upstream in the supply chain from the retailer through to the wholesaler and manufacturer due to the variance of orders which may be larger than that of sales."

The best way to think of this in terms of COVID is that in the early part of the cycle, the Federal Reserve was pouring trillions of dollars into the economy to ensure that the market didn't collapse. Consumers went out and spent all of that money on physical goods. At the same time, production in China and the U.S. was shut down or limited. The combination – stimulating consumption but limiting production – caused the American consumer to burn through almost all inventory.
