US SUPPLY DISRUPTIONS INDEX (US SDI) -- March 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 April, US SDI remains elevated and increased to 1.52 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 South (1.18pp), Midwest (1.53pp) and Northeast (1.09pp) remain above historical averages, while the West (0.63pp) is closer to normal levels. 

  • Among product categories, non-durables (0.28pp) have reverted to pre-2020 levels, while manufacturing (1.45pp) and durable (1.29pp) product categories still face elevated disruption levels. 

  • Among countries of origin, significant disruptions with China (1.21pp) and South Korea (2.42pp) still persist, whereas consumer-supplier relationships with France (0.67pp) have returned to pre-2020 levels during the first quarter of 2023.
