Prologis Research, Prologis' research department, expects that the current market instability will require a change in the way stocks are stored. Until the pandemic, global supply chains relied on a "just-in-time" model, for which the smooth flow of goods is key. However, the pandemic and other factors (such as climate change, geopolitics and labor market tensions) have disrupted this smooth flow and caused commodity shortages, instability and higher costs.
