American consumers have been on a spending spree since the pandemic eased. A measure of this has been the daily tally of container ships waiting outside the busy ports of Los Angeles and Long Beach, California. These two ports serve as entry points for about 40% of all goods imported into the United States (US). The queue of ships reached are cord of 73 on 19 September 2021 and was still extremely long last weekend, frustrating retailers and highlighting the pressures on the US supply chain.
