Global financial cycles since 1880

Global financial cycles: a long-term affair

Today’s financial system is global: credit and several financial asset classes show booms and busts across countries, sometimes with severe repercussions to the global economy. Yet it is debated to what extent common dynamics rather than domestic cycles lie behind financial fluctuations and whether the impact of global drivers is growing. In a recent Staff Working Paper, we observe various global financial cycles going as far back as the 19th century. We find that a volatile global equity price cycle is nowadays the main driver of stock prices across advanced economies. Global cycles in credit and house prices have become larger and longer over the last 30 years, having gained relevance in economies that are more financially open and developed.

The macro consequences of dollar shortages and central bank swap lines during the Covid-19 pandemic

Fernando Eguren Martin

Dollar shortages in funding markets outside the United States have been a recurrent feature of the last three major crises, including the turmoil associated with the ongoing Covid-19 pandemic. The Federal Reserve has responded by improving conditions and extending the reach of its network of central bank swap lines, with the aim of channelling US dollars to non-US financial systems. Despite the recurrence of this phenomena, little is known about the macroeconomic consequences of both dollar shortage shocks and central bank swap lines. In this post (and in an underlying Staff Working Paper) I provide some tentative answers.

Playing with fire: banks’ distressed sales under solvency and liquidity constraints

Caterina Lepore and Jamie Coen

Many commentators on the global financial crisis identified ‘fire sales’ as one of the key mechanisms by which shocks to banks were amplified and transmitted across the wider financial system. When firms in distress sell assets held by other institutions at discounted prices, losses can spread through the financial system as prices fall, amplifying the initial stress. In a working paper published last year, we explored this mechanism by presenting a new model of fire sales. In doing so, we answer the following questions: Which types of financial shocks combine to produce fire sales? How can banks optimally liquidate their portfolios when forced to do so? How big a risk are bank fire sales?

Why fragmentation of the global data supply chain poses risks to financial services

Matthew Osborne and David Bholat

Every minute of the day, Google returns over 3.5 million searches, Instagram users post nearly 50,000 photos, and Tinder matches about 7,000 times. We all produce and consume data, and financial firms are key contributors to this trend. Indeed, the global business models of many firms have amplified the data-intensity of the financial services industry. But potential fragmentation of the global data supply chain now poses a novel risk to financial services. In this blog post, we first discuss the importance of data flows for financial services, and then potential risks from blockages to these flows.

Special series: Covid-19 Briefings

Belinda Tracey

Starting today, Bank Underground (BU) is launching a special series of ‘Covid-19 Briefings’. These posts are different to our regular posts – rather than containing primary analysis or the author’s own research, they instead aim to summarise key lessons from the early literature on a particular area of the economics of Covid-19. Each post focuses on a different area, and aims to provide an introduction to key papers, rather than a comprehensive overview of all the literature. As with any BU post, they are the views of the authors, not necessarily those of the Bank. We hope our readers find them helpful in understanding the new, rapidly developing and fast growing body of work on the economics of Covid-19.

There’s more to house prices than interest rates

Lisa Panigrahi and Danny Walker

The average house in the UK is worth ten times what it was in 1980. Consumer prices are only three times higher. So house prices have more than trebled in real terms in just over a generation. In the 100 years leading up to 1980 they only doubled. Recent commentary on this blog and elsewhere argues that this unprecedented rise in house prices can be explained by one factor: lower interest rates. But this simple explanation might be too simple. In this blog post – which analyses the data available before Covid-19 hit the UK – we show that the interest rates story doesn’t seem to fit all of the facts. Other factors such as credit conditions or supply constraints could be important too.

All you need is cash

Andreas Joseph, Christiane Kneer, Neeltje van Horen and Jumana Saleheen

Financial crises affect firm growth not only in the short-run, but even more so in the long-run. Some firms permanently gain while others lose and cash is a crucial asset to have when the credit cycle turns. As we show in a new Staff Working Paper, having cash at hand allows firms to continue to invest during the crisis while industry rivals without cash have to divest. This gives cash-rich firms an important competitive edge that not only benefits them during the crisis but that gives them an advantage that lasts way beyond the crisis years.

Possible pitfalls of a 1-in-X approach to financial stability

Adam Brinley Codd and Andrew Gimber

Meteorologists and insurers talk about the “1-in-100 year storm”. Should regulators do the same for financial crises? In this post, we argue that false confidence in people’s ability to calculate probabilities of rare events might end up worsening the crises regulators are trying to prevent.

Margin call! Cash shortfall?

Marco Bardoscia, Gerardo Ferrara and Nicholas Vause

Participants in derivative markets collect collateral from their counterparties to help secure claims against them should they default. This practice has become more widespread since the 2007-08 financial crisis, making derivative markets safer. However, it increases potential ‘margin calls’ for counterparties to top up their collateral. If future calls exceed available liquid assets, counterparties would have to borrow. Could money markets meet this extra demand? In a recent paper, we simulate stress-scenario margin calls for many of the largest derivative-market participants and see if they could meet them – including because of payments from upstream counterparties – without borrowing. We compare the sum of any shortfalls with daily cash borrowing in international money markets.
