Banks come in different shapes and sizes. Do prudential regulations that work well for big banks work as well for small ones? To help us find out, we measure the effectiveness of some key regulatory ratios as predictors of bank failure. We do so using ‘receiver operating characteristic’ – or ‘ROC’ – analysis of simple threshold rules. When we do this, we find that we can use the ratios we test to make better predictions for large banks than for small ones. This provides evidence that an efficient set of regulations for large banks might not be as efficient for small ones.
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).
‘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.

‘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.

The Great Financial Crisis demonstrated an important feedback loop between banks’ capitalisation and funding costs. As banks’ capitalisation declined, banks’ wholesale creditors responded by demanding higher interest rates to lend to them. In turn, higher funding costs dented banks’ profitability, further weakening their capitalisation. Quantifying the relationship between funding costs and market-based measures of leverage – a proxy for bank solvency – is key to understand how banks might fare in a future stress situation – for instance as part of regulatory stress tests.

Bank failures are very costly for society. Following the 2007/2008 global financial crisis, international regulators introduced a package of new banking regulations, known as Basel III. This includes a wider range of capital and liquidity requirements to protect banks from different risks. But could the additional complexity be unnecessary or even increase risks, as some have argued? In a recent staff working paper, we assess the value of multiple regulatory requirements by examining how different combinations of metrics might have helped prior to the 2007/2008 crisis in gauging banks that subsequently failed. Our results generally support the case for a small portfolio of different regulatory metrics: having belts and braces (or suspenders) can strengthen the resilience of the banking system.
The Covid-19 (Covid) pandemic is a major shock to the economy but unlike traditional crises or credit crunches, its origin is exogenous to the financial sector. The economy’s ability to recover from the impact of the pandemic will however depend in part on the availability of credit. This raises the question how banks absorb a large shock which originates from outside the financial sector. To answer this question this post reviews the literature on how previous pandemics and natural disasters in the developed world affected banks’ balance sheets. One key message stands out: banks that are more rooted in their market are much more likely to continue lending when faced with the economic fallout from such shock.
This year marks 25 years since the failure of Barings Bank. On Sunday 26 February 1995, the 200-year old merchant bank blew up thanks to derivatives trading, which it believed was both risk-free and highly profitable. It was neither of these things. The firm’s star trader was illicitly pursuing a strategy akin to ‘picking up pennies in front of a steam-roller‘. The steamroller arrived in the form the Kobe earthquake. The star trader’s losses ballooned and he doubled up on his bets, unsuccessfully. Barings went bankrupt. The episode captured the public imagination, and helped lead to the creation of a new regulator in the UK.
On 16 June 1933, as the nationwide banking crisis was reaching a new peak, freshly elected US President Franklin D. Roosevelt put his signature at the bottom of a 37-page document: the Glass-Steagall Act. Eight decades later, the debate still rages on: should retail and investment banking be separated, as Glass-Steagall required? In a recent paper, we shed new light on the consequences of this type of regulation by examining the recent UK ‘ring-fencing’ legislation. We show that ring-fencing has an important impact on banking groups’ funding structures, and find that this incentivises banks to rebalance their activities towards retail mortgage lending and away from capital markets, with important knock-on effects for competition and risk-taking across the wider banking system.
This post contributes to our occasional series of guest posts by external researchers who have used the Bank of England’s archives for their work on subjects outside traditional central banking topics.
In 1944, the Bank of England’s historian, John Clapham, looked back at the ways in which the Bank had changed since 1914 and remarked:
‘ . . . it would not be fantastic to argue that the Bank in 1944 was further . . . from 1914 than 1914 was from 1714.’
