Governments are battling to figure out the right trade response to the COVID-19 pandemic amid escalating economic turmoil. Initial responses show the difficulties and the risk of getting things wrong. An understandable response of locking everything down to slow the spread of disease and keep control of equipment also limits the movement of essential workers and stops critical supply chains from functioning effectively

Over 50 countries were restricting the export of certain medical supplies by mid-March, and travel barriers are in place worldwide – in many cases even blocking movement between sub-national regions. Measures away from the border like the closure of hotels mean supply-chain workers – from research scientists to engineers to cargo pilots – are constrained from operating effectively.

Firms are calling for governments to intelligently and flexibly implement pandemic response policies to avoid freezing the supply system for medical goods at a time when they’re most needed. In the shorter term, businesses also need flexibility to adapt production to manufacture critical goods; the supply chain finance to keep suppliers working, and the legal adaptability to cope with practical problems such as accepting digital signatures to minimize human contact. Critical goods should not be sitting for days waiting to clear customs.

In the long term, the need for visibility into supply chain data, and ability to provide services digitally across borders, whether for telehealth or education, is clear. Trade decisions made now will help shape whether we have diverse, cost-effective and accessible sources of supply in the future.

Beyond the immediate need for supplies, questions are being raised about the risk inherent in current supply chain structures. Over recent decades, supply chains have globalized, specialized and become leaner or just-in-time. They are more efficient, less risky in certain areas, but potentially more exposed to a breakdown of cooperation.

Through this period, supply chain managers have encountered numerous shocks, often coming away a little wiser, with a stronger supply chain. The Great East Japan Earthquake and tsunami, Thailand’s flooding, the Eyjafjallajokull volcano, the maritime piracy upsurge, the e-coli-infected vegetable outbreak – all these shook supply chains across whole regions.

A 2012 World Economic Forum survey of supply chain professionals ranked disruptions most likely to provoke significant and systemic effects on supply chain networks. The list included pandemics, natural disasters, extreme weather, conflict, demand shocks, ICT breakdowns, and export/import restrictions. Other than natural disasters and weather, the others are possible to influence, if not fully control. Given this, it’s extremely discouraging, from both human and economic perspectives, to see the growing list of export restrictions being placed on medical supplies.

However, the triggers of supply chain disruption are hard to predict, and sometimes neither controllable nor influenceable. The robustness of networks is paramount to ensuring demand can be met with supply even in extraordinary times. COVID-19 and related responses are delivering an extraordinary shock both on supply and demand sides to the global economy – by shuttering production and cutting consumption – even as demand for healthcare materials soars.

Both governments and business have responded to past difficulties with efforts to improve supply chain resilience. A critical element of this is information. Indeed, the same survey found that four of the top five global supply chain vulnerabilities relate to visibility along long supply networks.

Supply chain planners have made good progress in decreasing fragility, not least by increasing information and better aligning risk with responsibility. Risk managers reflecting on previous disruptions highlighted five priority strategies to improve further: Risk quantification, scenario planning, data sharing, trusted networks and multi-stakeholder input to legislation.

As governments, medical professionals and logisticians respond to the current crisis, these five recommendations from past supply chain shocks are worth remembering.

The global economy and international trade is currently experiencing a massive shock, with steep demand reductions in many areas, and spikes in others. A drastic reduction in foreign investment is happening. As demand and supply for medical equipment are most mismatched in developing countries, they will suffer the brunt of supply chain breakdowns. We need to avoid aggravating this via trade or investment restrictions. Communications and flexibility are needed in the short term for crisis response.

It is not too soon to think hard about restarting economies and building back a resilient and responsive trade system able to cope with the next disruption whatever it may be. Decoupling and reshoring, though superficially tempting, are overly simplistic proposals. Rather, demonstrating that as nations we care about those outside our borders will strengthen our response today and secure resilient supply chains for tomorrow.
