Abstract:
The emergence of cryptocurrencies/crypto assets has allowed the provision of a new form of financial services, including payments and loans, known as decentralised finance (DeFi). Crypto assets currently represent only about 1 percent of total global financial assets and it is unlikely, in its current form, that DeFi will become a substitute for the traditional financial system, for three reasons. First, while decentralisation is very innovative, in practice the technology required to replace the role of intermediary is slow and costly in terms of energy use. This has led some crypto networks to adopt more centralised solutions to the problem of verification. Second, the automaticity behind the transactions does not allow for any legal recourse. If something goes wrong, there is no way to stop or reverse a transaction once it has been initiated. It is very difficult to imagine DeFi scaling up without the ability to challenge outcomes. Third, and perhaps most importantly, DeFi is for the most part self-referential. Crypto assets are exchanged for other crypto assets without being employed in activities that stimulate economic growth by creating jobs or facilitating investment. It is not likely for DeFi to grow enough to replace traditional finance unless it helps growth. Nevertheless, the technology that enables DeFi and crypto assets, distributed ledger technology (DLT), is very innovative and has managed to remove the intermediary without compromising the safety and finality of financial transactions. Hence, it is likely that the technology behind crypto assets and DeFi will feed into the mainstream and offer efficiency gains.

Abstract:
The process by which central banks take decisions has evolved over the years, with a tendency towards independence and decisions taken by committees rather than individuals. Monetary policy committees can be set up formally in different ways, traditionally falling into one of two categories: individualistic or collegial. Individualistic committees reach decisions by voting and publish the votes of each of their members, while in collegial committees, decisions are typically reached collectively. The European Central Bank is an example of the latter, while the Bank of England follows an individualistic approach. Focusing on decision-making, a relevant question is whether the formal set-up in practice leads to different ways of deliberating and reaching monetary policy decisions. We look at decisions taken by the Bank of England, the Federal Reserve and the European Central Bank over more than 20 years to evaluate how different the decision-making process is in these three central banks. The results indicate that, irrespective of the committee type, their approach to consensus building when they take decisions is similar. The three central banks seem to value reaching decisions by unanimity, both on interest rates – the prime monetary policy instrument by definition – and on asset purchases. Decisions to tighten monetary policy are more often taken unanimously than decisions to ease monetary policy. When maintaining policy unchanged, decisions are usually backed by most committee members.

3. Low interest rates in Europe and the US: one trend, two stories

Abstract:
In both Europe and the United States, interest rates have been declining for more than fifteen years. For much of this period, real interest rates have been negative and they are expected to remain negative for at least another decade. The literature associates this decline in interest rates with a similarly protracted decline in productivity. But the decline in productivity appears paradoxical given major technological advances. The decline in the price of capital is underpinned by the factors that have caused a decline in demand for capital, as well as a relative increase in its supply. On the supply side, aging and an increase in overall macroeconomic risk since the financial crisis have both led to increased savings. On the demand side, the increase in the importance of intangible capital in production has reduced the demand for physical capital. Nevertheless, for the US, the literature has identified the increase in market concentration as the biggest factor responsible for the reduction in the overall demand for capital. Digital innovation has led to the creation of champion firms that have captured big market shares and have been able to prevent others from entering not only the US market, but markets globally. This has dampened investment. Europe is affected by US digital dominance, but other factors, including aging and increased risk, are more prominent in sustaining the downward pressure on interest rates. In particular, the lack of risk capital, in the context of capital markets, contributes to this downward pressure in the EU. As the knowledge economy relies increasingly on intangible capital, a bank-based system that requires collateral is not well suited to finance investments. A lack of suitable finance will remain an important factor in the downward pressure on interest rates. The structural factors behind the downward pressure on interest rates imply that macroeconomic policy will have a reduced role in managing aggregate demand. Monetary policy in the euro area will be more about preventing financial fragmentation and less about stimulating demand. Equally, fiscal policy will have more of a supporting rather than stimulating role. Tackling the structural decline in market dynamism and therefore in real rates will require structural policies to reduce market power globally and ensure the creation of capital markets in the EU.

4. The financial fragility of European households in the time of COVID-19

Abstract:
The concept of household financial fragility emerged in the United States after the 2007-2008 financial crisis. It grew out of the need to understand whether households’ lack of capacity to face shocks could itself become a source of financial instability.
