It is difficult to start any article without referring to the threat presented by the coronavirus sweeping across countries. The human impacts are clearly devastating for anyone affected, even if the overall impact is at present relatively small in the context of major pandemics through history.

The economic and financial impacts are also proving significant. Less than two months after the first reported case, the OECD lowered its forecast for global GDP growth in 2020 by one-fifth in response the virus.

The speed and scale of downturns in stock markets mirror this response. Since the 1970s there have been four periods during which global equities have fallen more than 10% in five days; the 1987 crash, the 2008 global financial crisis, the 2011 eurozone crisis and the first few months of 2020.

That market response contrasts with the effect of similar crises in the past. Notably, major equity indices rose while Spanish flu raged in 1918-19; the end of the Great War provided a boost but stocks were relatively unaffected even before its end.

The world is a very different place to that of 1918, or even that of a decade ago when the spread of swine flu coincided with a 40% rise in the Dow Jones Industrial Average.

Companies are more dependent than ever on the licenses to operate society provides, supply chains are more complex and connected than ever, social and environmental tensions are more acute than in the past, and regulation is accelerating to address growing imbalances between corporate success and social needs.

Companies don’t operate in a vacuum

The changing backdrop underlines the importance of sustainability to the investment industry. If they ever did, financial markets no longer exist in isolation from social or environmental challenges. Companies’ fortunes are intrinsically tied to their ability to navigate changes in the societies on which they rely.

We have long argued that companies don’t operate in a vacuum. Their success reflects their ability to adapt to challenges and trends in the societies to which they belong. That is more true now than ever; social and environmental challenges, and investment drivers, are increasingly overlapping.

As a result, environmental and social problems are increasingly clear financial risks, moving up corporate agendas to drive long-term strategy and growth plans. As investors, our ability to examine companies and separate winners from losers has improved as corporate sustainability reporting has become mainstream.
