Rising Inventories Pose A Threat To Businesses And The Economy
At the end of 2011, companies held $1.26 worth of inventory for every dollar’s worth of monthly sales. Their holdings now amount to $1.38. (Inventory data.) As an economist I cannot know what the right level of inventories is. Careful decisions don’t bother me, but I’m not convinced that careful is more common than complacent.
Companies have been trimming inventory levels for many years. Twenty years ago businesses held $1.49 of inventory for every buck of monthly sales. With improved technology, companies today know what is in the store, what’s in the warehouse, when new supplies will be delivered, and what’s delayed in shipment. Walmart gets—and deserves—a lot of credit for better inventory management, but good practices have spread across the entire economy. So why the recent reversal?
Inventories spike up whenever the economy goes soft, but that’s not really the case in the last four years. The recent upward trend is present at all levels: manufacturing, wholesale and retail.
More likely is that inventories have risen because of complacency. Sales have grown at a moderate pace, not great but not bad. Few businesses are in crisis. Interest rates are low, so it does not cost much to tie up working capital in inventories. This is a breeding ground for complacency.
I have been recommending to my clients who hold inventories that they do two things. First, review their replenishment rules. It’s common to set up rules and then not revisit them. This is a good time to examine the rules in place. Second, see if your company is really following its rules. Sometimes procedures are set up and ignored. If that’s the case, turn your attention to your purchasing practices right away.
