The coronavirus outbreak will have more impact on global trade than the US-China trade war, with £20 billion (NZ$40.5b) a week lost on exports, a study has predicted.
Euler Hermes, which insures payments to exporters, estimates that the weekly loss will be equivalent to a rise in the world import tariff on goods by 1 percentage point - more than the effect of the trade dispute last year, which was 0.7 percentage points.
It said the loss will come via shocks on both the supply and demand sides as manufacturing production stalls, exports to China fall, and travel is reduced. Germany, Hong Kong, South Korea, the US and Japan are the most exposed.
"While the negative spillovers from the coronavirus epidemic will not last for more than three months, we doubt the global economy is strong enough to catch up entirely after the loss, given that the growth acceleration in the second half will be capped by US-driven uncertainty," Euler said.
The disruption to global supply chains could reach the British high street by the end of the month if the outbreak is not contained. Companies have told analysts at UBS that Chinese factories being shuttered until the end of February would start to impact the availability of stock at retail giants.
