When the U.S. Commerce Department reported that retail sales fell 1.9 percent in December 2021, most attributed it to consumers having shifted their holiday shopping to earlier in the season. Amazon had postponed its Prime Day from its usual July dates to October in 2021. Retailers were rolling out holiday promotions as early as late September, with most underway in October. Yet, inflation in December 2021 had hit a 40-year high, according to data from the U.S. Bureau of Labor Statistics.Consumers were noticing higher prices, but were not indicating that this would impact their spending. However few anticipated the coming Russia-Ukraine war and its impact on energy and other commodity prices.No One Saw It ComingHistorically there hasn’t been a bust-boom-bust cycle like what we’ve been experiencing now for nearly three years. After scrambling to fill distribution centers ahead of the season, suddenly brands and retailers are finding that they had too much inventory. To make matters worse, economic headwinds are causing a slowdown in consumer spending. For a growing number of brands, the question is no longer whether consumer demand will slow, it’s how much will it slow? And what to do with the mountain of inventory that is becoming increasingly difficult to move?“The bullwhip effect has created a massive overstock of inventories and wreaked havoc on global supply chains as companies try to recover from the pandemic economy,” according to Freightwaves.The chaos that was driven by surging demand is now being replaced by desperation as consumer demand is clearly reversing course. This particularly bad news heading into peak retail seasons of back-to-school and then holiday.Even Big Players with Big Data Were BlindsidedTypically it's the smaller players with less predictive resources that get caught off guard. This time even the most sophisticated technology did not help retailers or brands see what was coming.It’s not only apparel or big box retailers, like Walmart and Target, which in June reported inventory overstock. Nikkei Asia reported that electronics giant Samsung was facing its own bullwhip effect of too much inventory and asked upstream suppliers to cut back production by as much as half in the month of July.The bullwhip effect describes a scenario in which temporary surges in retail demand are magnified and exaggerated by upstream manufacturers and suppliers, who rapidly increase production well beyond the level that can be supported by consumers. Eventually, retailers find themselves with more inventory than they can sell, and what started as a goods shortage ends up as a goods surplus.The confluence of the build up in inventories with rising inflation, then magnified by the impact of the Russia-Ukraine war and other geopolitical tensions on consumer sentiment, has caused two years of surging demand to come to what seems like an abrupt halt.Unfortunately, just as consumers were cutting back on spending, inventory that had been stuck in ports started to arrive at retailers’ warehouses. Could This Be the Cure We’ve Been Waiting For?It is often said that one of the best ways to end high prices is high prices. Rising prices usually lead to less spending and less spending to lower prices. Thus there could be a ceiling on both costs and retail prices.While this might not be the outcome most brands and retailers were hoping for, at this point anything that gets supply chains to normalize will be welcomed by both suppliers and buyers.
