Making Supply Chains More Resilient

The current global semiconductor shortage illustrates how geographic clustering of input suppliers can generate upheavals in the rest of the world. Business leaders and policymakers must think now about how to minimize the effects of future exogenous shocks on production networks and the global economy.

MUNICH – Automobile and electronics manufacturers worldwide have recently had to reduce output because a severe drought in Taiwan has hit the island’s production of semiconductors. This and other global supply-chain disruptions – many of them caused by the COVID-19 pandemic – have prompted advanced economies to take steps to mitigate the potential impact. But what types of government action make economic sense?

Supply-chain bottlenecks can have a significant economic effect. Germany, for example, imports 8% of its intermediate products from low-wage countries (the United States relies on these economies for just 4.6% of its inputs). Problems with input deliveries recently led Germany’s Ifo Institute to lower its forecast for German GDP growth this year by almost half a percentage point, to 3.3%.

This vulnerability helps to explain why the European Union has earmarked part of its €750 billion ($884 billion) Next Generation EU recovery fund to bolster Europe’s semiconductor design and manufacturing capabilities. The US chipmaker Intel plans to invest in several European countries and to open a semiconductor factory in the region with EU help.
