Capital flights during Covid-19

Fernando Eguren-Martin, Cian O’Neill, Andrej Sokol and Lukas von dem Berge

While planes were grounded, capital flew out of emerging market economies in response to the acceleration in the spread of the virus in the early stages of the Covid-19 pandemic. Was this capital flight predictable once you account for the sudden deterioration in the global financial environment? In this post we present a model that helps to think about how financial conditions and international capital flows are linked. We then apply this methodology to events observed between March and May 2020, and find that the model predicted a large increase in the likelihood of capital flight. However, the scale of outflows was abnormally large even once the sharp tightening in financial conditions is accounted for.

When bigger isn’t better: UK firms’ equity price performance during the Covid-19 pandemic

Tommaso Aquilante, David Bholat, Andreas Joseph, Riccardo M Masolo, Tim Munday and David van Dijcke


Covid-19 (Covid) has had heterogeneous effects on different groups of people. For example, it’s had larger negative impacts on contact-intense occupations (Leibovici, Santacreu and Famiglietti (2020)), low wage earners (Joyce and Xu (2020)) and low-income households (Surico, Känzig and Hacioglu (2020) and Chetty et al (2020)). In this blog, we show that UK listed firms have been heterogeneously impacted too (compare Hassan et al (2020); Griffith, Levell and Stroud (2020)). Surprisingly, small firms’ stock prices have been more resilient on average. Or, to put it differently, being bigger hasn’t been better for firms during the pandemic. However, being big with a modern tilt towards intangibles turned out to be beneficial too.

Hubble? Bubble? Valuation trouble?

Can Gao, Ian Martin, Arjun Mahalingam and Nicholas Vause

Since Covid-19-related crashes in March, major stock indices around the world have bounced back. This is despite little or no recovery in corporate earnings expectations. As a result, forward-looking price-to-earnings ratios have increased, rising above long-run average values in most large advanced economies and approaching record highs in the United States. Commenting on such valuations, some market participants have suggested there is ‘a great deal of optimism priced into the market’ and that stock prices ‘cannot defy economic gravity indefinitely’. This post takes a closer look at stock valuations, focusing on the UK, and drawing both on a textbook model and new research from academia.

Market fragility in the pandemic era

Gerardo Ferrara, Maria Flora and Roberto Renò

Financial markets process orders faster now than ever before. However, they remain prone to occasional dysfunction where prices move away from fundamentals. One important type of market fragility is flash events. Identifying such events is crucial to understanding them and their effects. This post displays the results from a new methodology to identify these, but also longer lasting V-shaped events, as we show here with an application to three sovereign bond markets.

Informed trading in government bond markets

Robert Czech, Shiyang Huang, Dong Lou and Tianyu Wang

Government bond yields serve as a benchmark for virtually all other rates in financial markets. But what factors drive these yields? One view is that yields only move notably when important news hit the market, for example monetary policy announcements. Others suspect that some investors have an information advantage due to their access to costly information (e.g. data providers) or more accurate interpretations of public information. In a recent paper, we show that two investor groups – hedge funds and mutual funds – have an information edge in the UK government bond (gilt) market, and that these two investor types operate through different trading strategies and over different horizons.

Covid-19 briefing: cross-border dollar funding

Saleem Bahaj and Fernando Eguren-Martin

The US dollar has a dominant role in the international financial system. The fact that trade and cross-border investment are overwhelmingly dollar-denominated means that non-US banks are heavily reliant on dollar funding (Aldasoro and Ehlers (2018)). This funding dried up during the Covid-19 epidemic, prompting the use of central bank swap lines as a policy response. This post looks at recent research on why dollar funding dried up in March, the efficacy of swap lines and the implications for cross-border banking, exchange rates and the international financial system.

Bitesize: Emerging market currency risk: evidence from the COVID-19 crisis

Simon Lloyd, Giancarlo Corsetti and Emile Marin

A striking regularity around global economic crises is that the dollar tends to appreciate sharply against emerging market (EM) currencies as capital flows out of EMs. In this respect, the adjustments observed since the onset of the COVID pandemic are no exception. Since the end of February, EM currencies have depreciated by around 15% (on average) and non-resident portfolio outflows from EMs summed to nearly $100 billion over a period of 45 days.

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.

Pricing GDP-linked bonds

Fernando Eguren-Martin

GDP-linked bonds are sovereign debt instruments with repayments linked to the evolution of a country’s GDP. Originally proposed by Shiller in the 90s, they have recently been re-invoked in the debate around the policy response to the Covid-19 pandemic. These instruments present an obvious attraction for issuers: repayments are lower at times when the economy is growing relatively slowly, which typically coincides with lower tax earnings. A greater share of the risk of weak growth is then transferred to investors, who will require a compensation given they are typically risk-averse. Therefore, while the design is attractive ex-ante, a relevant question facing sovereigns willing to issue this type of instrument is `at what cost?’. In this post (and in an underlying Staff Working Paper) we provide some tentative answers.

Why cryptocurrency markets defy the laws of economics

Peter Zimmerman

Speculative buying can drive cryptocurrency prices down. This is contrary to the usual laws of economics. Blockchain technology limits how quickly transactions can be settled. This constraint creates competition for priority between different users. The more speculative activity there is, the longer it takes to make a payment. But the future value of cryptocurrency depends on its usefulness as a means of payment. Speculation therefore affects price formation through a channel that does not exist for other asset classes. This can explain the high price volatility of cryptocurrencies, and is consistent with the low adoption rate so far.
