Household debt and consumption revisited

Philip Bunn and May Rostom

The academic literature finds that the build-up of household debt before the 2008 financial crisis is linked to weaker consumption afterwards. But there is wider debate over the mechanisms at play. One strand of literature emphasises debt overhang acting through the level of leverage. Others find it was over-optimism acting through leverage growth. In this post, we revisit our previous analysis on leverage and consumption in the UK using synthetic cohort analysis. The correlation between leverage measures and their link to other macroeconomic variables mean it’s challenging to tease out their effects. Yet we find that whilst both mechanisms played a role, there is evidence that debt overhang linked to a tighter credit constraints was the bigger driver.

Slow recoveries, endogenous growth and macroprudential policy

Dario Bonciani, David Gauthier and Derrick Kanngiesser

Following the global financial crisis in 2008, central banks around the world introduced tighter banking regulations to increase the resilience of the financial sector and reduce the risks of severe financial disruptions during economic downturns. This fact has motivated a large body of literature to assess the role that macroprudential (MacroPru) policies play in mitigating the severity of recessions. One common finding is that the benefits of MacroPru are relatively minor within standard dynamic stochastic general equilibrium (DSGE) models. In a new paper, we show that MacroPru becomes significantly more important in a model that accounts for the long-term negative consequences of financial disruptions.

Does corporate leverage amplify economic downturns? A dive into the literature

Sudipto Karmakar, Alexandra Varadi and Sarah Venables

This post reviews the literature on the consequences of debt for corporate and macroeconomic outcomes, drawing both on the pandemic period and on previous financial crises. Lessons from previous crises show that high leverage can amplify corporate risks and economic downturns by: increasing reliance on external financing that may dry up in stress; through debt overhang problems; or by increasing linkages between corporates and other sectors of the economy. Corporate debt may also be correlated with negative outcomes in the pandemic as well, but it is still early to draw direct conclusions.

What do two million accounts tell us about the impact of Covid-19 on small businesses?

Compass on old map

This post is the second of a series of posts about the Covid-19 pandemic and its impact on business activity.

Covid-19 led to a sharp reduction in economic activity in the UK. As the shock was playing out, small and medium-sized businesses (SMEs) were expected to be more exposed than larger businesses. But until now, we have not had the data to analyse the impact on SMEs. In a recent Staff Working Paper we use a new data set containing monthly information on the current accounts of two million UK SMEs. We show that the average SME saw a very large drop in turnover growth and that the crisis played out very differently for different types of SMEs. The youngest SMEs in consumer-facing sectors in Scotland and London were hit hardest.

On the origin of systemic risk

Giovanni Covi, Mattia Montagna and Gabriele Torri

Systemic risk in the bank sector is often associated with long periods of economic downturn and large social costs. In a new paper, we develop a microstructural contagion model to disentangle and quantify the different sources of systemic risk for the euro-area banking system. Calibrated to granular euro-area data, we estimate that the probability of a systemic banking crisis was around 3.6% in 2018. Seventy per cent of the risk stems from economic risks, with fire sales and contagion risk accounting for most of the remainder and only a small role for interbank exposures. Our findings suggest that correlations among banks’ losses play a crucial role in the origins of systemic risk.

What types of businesses have used government support during the Covid-19 pandemic?

Will Banks, Sudipto Karmakar and Danny Walker

This post is the first of a series of posts about the Covid-19 pandemic and its impact on business activity.

During the pandemic, UK businesses have received unprecedented levels of government support, set to total 9% of GDP. This has mainly been through the Coronavirus Job Retention Scheme (CJRS), under which 1 in 3 employees have been furloughed, and the government-guaranteed loan schemes that were used by 1 in 4 businesses. Despite the scale of this support, little has been said about which businesses received it. In this post we combine data on loan scheme and CJRS usage with a data set on the characteristics of businesses. We find that small, relatively old and sophisticated, labour-intensive businesses in the sectors most vulnerable to the impacts of the pandemic are most likely to have received both types of support.

Procyclicality mechanisms in the financial system: what we know and some open questions

Robert Czech, Simon Jurkatis, Arjun Mahalingam, Laura Silvestri and Nick Vause

Financial markets reflect changes in the economy. But sometimes they amplify them too. Both of these roles were evident as the Covid-19 (Covid) pandemic materialised. As the economic outlook deteriorated, risky asset prices fell in reflection of that. And those falls were amplified as some investors reacted by liquidating assets. That also amplified increases in financing costs for companies issuing new debt or equity, which could have further damaged economic prospects. Various ‘procyclical’ mechanisms contributed to this macrofinancial feedback loop, as shown in Figure 1. This post reviews findings from research about these particular mechanisms, covering (i) how they work, (ii) how strong they are and (iii) how they might be mitigated. And, where there are gaps, it suggests new research.

Where is IFRS 9 taking the cost of funding of banks?

Mahmoud Fatouh

IFRS 9 versus IAS 39

In 2018, IFRS 9 came into effect, replacing IAS 39. IFRS 9 has important implications especially for banks, as they mostly hold financial assets. IAS 39 is based on the incurred-loss model, which allows recognition of credit losses (in the form of provisions) only when there is objective evidence of impairment, dividing loans into performing and impaired loans (Figure 1). IFRS 9 introduces the more forward-looking expected loss model, under which provisions are equal to the expected credit losses. As illustrated in Figure 1, IFRS 9 classifies loans into three stages: Stage 1 loans (performing loans), Stage 2 loans (underperforming loans) and Stage 3 loans (nonperforming loans).

The Real Effects of Zombie Lending in Europe

Belinda Tracey

‘Zombie lending’ occurs when a lender supports an otherwise insolvent borrower through forbearance measures such as repayment holidays and temporary interest-only loans. The phrase was first coined for Japan in the late 1990s, but more recently several authors have documented that zombie lending to European firms has been widespread following the sovereign debt crisis (see Acharya et al (2019), Adalet McGowan et al (2018), Banerjee and Hofmann (2020), Blattner et al (2018) and Schivardi et al (2017)). In a recent paper, I examine whether these lending practices contributed to the subsequent low output experienced by the euro area. My findings suggest that zombie lending had negative consequences for output, investment and productivity in the euro area over the period 2011 to 2014.

Quantifying culture and its implications for bank riskiness

Joel Suss, David Bholat, Alex Gillespie and Tom Reader

‘Bad cultures’ at banks are often blamed for scandals and crises, from the global financial crisis to the mis-selling of payment protection insurance (PPI) in the UK. Yet surprisingly little research has tested this claim. This is because quantifying culture is difficult to do. Our working paper gives it a go. Leveraging unique access to data available to regulators, we diagnose the cultural health of the UK banking sector. We find that banks with organisational cultures two standard deviations below the sector average are associated with a 50% increased risk of failure.
