Abstract
We construct an index of US supply disruptions (US SDI, www.disruptions.supply) based on 200 million import transactions for the US spanning the last decade. Our aggregate index reveals that although there has been a notable improvement in US supply disruptions in 2022, these disruptions continue to remain higher than historical averages. Importantly, the data emphasize a substantial variation in the extent and duration of supply disruptions across different product categories, countries of origin, and regions within the US.
