US SUPPLY DISRUPTIONS INDEX (US SDI) -- August 2023

• Our monthly supply disruption index (US SDI) combines 200 million shipment-level import records for the US, measuring temporary disruptions in consumer-supplier pairs.

• In August, US SDI remains elevated at 1.71 percentage points (pp) of consumer-supply pairs temporarily disrupted as compared with the pre-2020 average. However, this is a decrease compared to the peak level of supply disruptions in June 2020, which was 2.85pp higher as compared with the pre-2020 average.

• Supply disruptions continue to persist with varying degrees across US regions, product categories, and countries of origin. 

  • Among US regions, disruptions for US firms in the West and the Midwest have been accelerating over the last several months. By August 2023, they reached 2.40pp and 2.78pp above historical averages, respectively. 

  • Among product categories, manufacturing (2.05pp) and durable (2.21pp) product categories still face elevated disruption levels. 

  • Among countries of origin, significant disruptions with China (2.12pp) and South Korea (1.65pp) still persist. Disruptions with European countries have also increased; for example, with Italy (3.05pp) and Spain (2.94pp).
