With a little help from my friends: counter-cyclical capital buffers during the Covid-19 crisis

Dennis Reinhardt and Carlos van Hombeeck

Have post-crisis reforms of banking regulation made banks and lending more resilient to the shock from Covid-19 and if so by how much? This blog takes one specific example – countercyclical capital buffers (CCyBs) – and shows that policy makers in a range of countries were able to quickly release these capital requirements, enabling banks to use the cumulated buffers. This released capital may in turn potentially help banks to support lending. And it will likely benefit lending in the country releasing requirements on buffers as well as banks’ lending to other countries, leading to potential positive international spillovers (see e.g. discussion of spillovers due to macroprudential policies by the ECB and others).

The language of rules: textual complexity in banking reforms

Zahid Amadxarif, James Brookes, Nicola Garbarino, Rajan Patel and Eryk Walczak

The banking reforms that followed the financial crisis of 2007-08 led to an increase in UK banking regulation from almost 400,000 to over 720,000 words. Did the increase in the length of regulation lead to an increase in complexity?

Setting boundaries: finding thresholds in bank regulation

Zahid Amadxarif, Paula Gallego Marquez and Nic Garbarino

“We’ve done a lot to lower prudential barriers to entry into the banking sector […] but have we done enough to lower the equivalent barriers to growth?” asked PRA CEO Sam Woods in a recent speech. To make regulation proportionate, policymakers adapt regulatory requirements to the risks posed by each firm. But regulators face a trade-off between addressing systemic risks in a proportionate way and limiting regulatory complexity. New thresholds can create complexity and cliff-edge effects that can discourage healthy firms from growing. We identify regulatory thresholds for UK banks and building societies using textual analysis on a new dataset that contains the universe of prudential rules.

Housing consumption and investment: evidence from the Help to Buy scheme

Matteo Benetton, Philippe Bracke, João F Cocco and Nicola Garbarino

Academics have made the case for mortgage products with equity features, so that gains and losses due to fluctuations in house values are shared between the household and an outside investor. In theory, the equity component expands the set of affordable properties, without increasing household debt, and default risk. These products have not become mainstream, but in a recent paper, we study a large UK experiment with equity-based housing finance — the Help To Buy Equity Loan scheme. We find that equity loans are mainly used to overcome credit constraints, rather than to reduce investment risk. Unconstrained household prefer mortgage debt over equity loans, suggesting optimism about house price risk. Equity loans could still contribute to house price inflation: we don’t find evidence that houses purchased with equity loans are overpriced, but an assessment of the aggregate effects is beyond the scope of the paper.

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.

Do emerging market prudential policies lessen the spillover effects of US monetary policy?

Andra Coman and Simon Lloyd

Prudential policies have grown in popularity as a tool for addressing financial stability risks since the 2007-09 global financial crisis. Yet their effects are still debated, with sanguine and more pessimistic viewpoints. In a recent Bank of England Staff Working Paper, we assess the extent to which emerging market (EM) prudential policies can partially insulate their domestic economies against the spillovers from US monetary policy. Using a database of prudential policies implemented by EMs since 2000, our estimates indicate that each additional prudential policy tightening can dampen the decline in total credit following a US monetary policy tightening by around 20%. This suggests that domestic prudential policies allow EMs to insulate themselves somewhat from global shocks.

The ownership of central banks

David Bholat and Karla Martinez Gutierrez

Around the world, central banks have a number of different ownership structures. At one end of the spectrum are central banks, like the Bank of England, that are wholly owned by the public sector. At the other end are central banks, like the Banca d’Italia, whose shareholders are wholly private sector entities. And there are central banks, like the Bank of Japan, that lie in-between. But do these differences matter?

In this blog post, we explore the variety of central bank ownership structures, both historically and globally.  We also suggest areas for future research on the topic.

New banking regulation: is it affecting the clearing of derivatives?

Jonathan Smith and Gerardo Ferrara

Just like the beginning of an unforeseen family argument, two key tenets of the post-crisis reforms have unexpectedly started to butt heads: the leverage ratio capital requirement and the mandatory requirement to centrally clear certain over-the-counter (OTC) derivatives.

Have FSRs got news for you?

Rhiannon Sowerbutts, Vesko Karadotchev, Richard Harris and Evarist Stoja

While communication has been recognised as an important aspect of monetary policy for over three decades and received an enormous amount of attention in the academic literature, there has been almost no attention paid to the importance and effects of financial stability communication. In a new working paper we examine financial markets’ reaction to the Financial Stability Report.

Give me more! Higher Capital Requirements and Loan Collateralisation

Sudipto Karmakar

How do banks adjust when faced with a sudden rise in capital requirements? The most frequent response, in the theoretical literature, is that they reduce lending or “deleverage” (see, e.g., Aiyagari and Gertler (1999); Gertler and Kiyotaki (2010). This is particularly true in crisis episodes when raising equity can be costly. However, in a new paper co-authored with Hans Degryse and Artashes Karapetyan, I show this is only part of the story. Banks may also ask borrowers to provide more collateral; collateralised exposures carry lower risk weights on average and hence enhance capital ratios. This requirement can adversely affect young and new borrowers that typically lack collateral to pledge and are also unlikely to have longstanding banking relationships.
