Major economic policy responses have been introduced to try to attenuate the impact of the Covid-19 pandemic on the economy. This document reviews the key measures taken by central banks and governments in a large number of countries as well as those taken by international organisations. It includes measures that were introduced through 20 April. It will be updated regularly.
The Covid-19 pandemic shows that the supply side warrants greater attention when conducting macroeconomic analyses. Very long global value chains may be optimal from a cost and price perspective, but operationally may be very complex and, in particular, fragile. A more resilient supply side comes with a cost, both at the micro and macro level. Solving this trade-off in a market economy is difficult, which, to some degree, leaves a role for public policy.
The Covid-19 pandemic has caused a jump in most of our uncertainty indicators. The media coverage based indicator is now at a record high. After stabilising at a high level, uncertainty of German companies has increased further whereas it has seen a big jump for US businesses. The behaviour of geopolitical risk is an exception...

Depending on the source, estimates of the number of ‘cryptocurrencies’ vary between 1,600 and 3,000. These crypto-assets struggle to fulfil the three economic functions of money, and so cannot be considered as such. Although their fairly modest uptake currently limits their economic impact, increased use could create risks in the transmission of monetary policy, money creation and financial stability. Several central banks are looking at the introduction of a ‘central bank digital currency’ (CBDC) in response to these challenges. However, far from being simply a substitute for private cryptocurrencies, these CBDCs would carry specific risks in terms of financial stability, most notably that of a ‘digital bank run’
Cities today concentrate more than half of the world population and more than 80% of global GDP. The underlying dynamics explaining their ever increasing importance are the result of a variety of positive externalities (thicker labor markets, knowledge spillovers, input sharing…) generating self-reinforcing effects. These rapid waves of urbanization have key implications for the production of goods and services, environmental quality and human development. The world is one of density spikes and disparities, driven by the unstoppable ascendance of metropolises. Greener and more inclusive cities should be promoted in order for them to remain livable. In this respect, public policies have an important role to play
The Paris climate deal, concluded at the COP21 in 2015, pleads for keeping global warming below 1.5°C above pre-industrial levels. However, in its latest report, the IPCC (Intergovernmental Panel on Climate Change) warns that current mitigation policies are insufficient to obtain this objective. Investments in renewable energy and electricity infrastructure have to be stepped up. The power sector has to be decarbonised, the use of electricity increased, and energy efficiency improved. Low carbon policies are difficult to implement because of commercial interests and social impact, in particular concerning the increase in carbon prices
Participants at the Paris Climate Conference COP21 agreed that global warming should be limited to 2°C. This would be the case if carbon concentrations could be stabilised at below 450 parts per million (ppm). However, simulations with climate models show that even at this level the risk of overshooting the 2°C limit is not negligible. From an economic point of view, it would be optimal to take early measures to reduce tail risks. To overcome public reluctance to make small sacrifices now to avoid substantial future damages, climate policies should be appropriately framed.
At a given moment during the month of February, the S&P500 was down 10% from its historical high. Using the commonly used definition, this meant it was in correction territory. This was considered by some as a healthy correction whereas others argued it might very well mark the beginning of an era of structurally higher volatility. Econometric research and model-based simulations show that the economic impact of equity market corrections is rather small. The stylised facts however show the key role of the reciprocal influence between equity markets and growth expectations. In this respect, particular attention should be devoted to the evolution of the corporate bond spread.
In May 2017, Donald Trump triggered a renegotiation of the North American Free Trade Agreement (NAFTA). Some proposals, 23 years after NAFTA came into force, aiming to introduce a chapter on the digital economy and strengthen the agreement’s current arrangements, have been generally welcomed. Others, such as a tightening of rules of origin and changes to trade remedies, have prompted concern.
In November 2016 the Bank for International Settlements (BIS) published an updated economic impact study of Basel III and the ongoing reforms, suggesting the existence of some room for manoeuvre in the creation of additional capital buffers. We demonstrate in this analysis that this room no longer exists in the eurozone, where the dominant role played by banks in financing increases the economic cost of new regulatory requirements and reduces the optimal bank solvency ratio, above which the economic cost exceeds the estimated benefit of tighter regulation.
World trade has slowed sharply compared to global GDP growth since 2012. Is the slowdown in world trade due to cyclical factors, and sluggish investment above all others? Or is it due to more far-reaching structural changes, in which case world trade is unlikely to return to the vigorous growth rates observed from the mid-1990s to the mid-2000s.
