"Supply chain crisis explained: The global supply chain suffers from port congestions, lack of containers, and skyrocketing demand.

"Now that the global economy is reopening as everyone waves goodbye to the coronavirus pandemic, demand has increased, leaving many industries unable to cope.

"The pandemic and lockdown have resulted in businesses’ inefficiency in meeting unprecedented consumer demand across all product categories. Recently, Morten Engelstoft, Chief Executive at Maersk-owned APM Terminal, echoed a similar sentiment. Engelsoft said that a “vicious circle” had been created by surging consumer demand, which put a strain on container groups, suppliers and logistics companies as they struggled to deliver goods. He further emphasized the need for the supply chain sector to break this vicious circle."
