Satellite Maps: Shanghai’s Supply Chain Standstill

China has mandated a strict “zero COVID” policy since the onset of the global pandemic, which has led to tight lockdowns across the country whenever cases have started to spike.

Recently, lockdown restrictions have been enacted in major cities like Shenzhen and Shanghai, as China deals with one of its worst outbreaks since Wuhan in December 2019.

Shipping volume has dipped drastically since early March this year, right after partial lockdowns began in Shanghai. By the end of March, as restrictions continued to tighten up, shipping activity dipped nearly 30% compared to pre-lockdown levels. And while activity has recently picked up, it’s still far below average shipment volumes prior to the recent lockdown.
