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.

Large amounts of capital flow across borders. But these can be destabilising. So can recipient countries employ prudential policies to offset monetary policy changes in centre countries? And does it matter where sending banks are located? Our findings suggest it does. Our case study of French banks operating in London – part of a broader international initiative – suggests prudential policies have a much bigger offsetting effect on French banks’ lending out of the UK’s financial centre than on their lending out of headquarters in France. In line with those observations, we uncover evidence of a ‘London Bridge’ in cross-border lending: the way French banks channel funds to the UK is responsive to prudential policies in the rest of the world.
Emerging markets (EMs) have become more exposed to the global financial cycle in recent years. Positive liquidity shocks – that is, a loosening of global funding market conditions – have led to exchange rate appreciations, reductions in long-term bond yields, stock market booms, and increased gross capital flows to EMs (Bhattarai et al (2018)). Negative liquidity shocks on the other hand constitute a tightening of financial conditions, reducing lending and real investment (Bruno and Shin (2015) and Avdjiev et al (2018)).
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.

For most of us buying insurance nowadays, price comparison websites offer plenty of choice. But how much competition in insurance markets is there? There are very few studies that address this question (see here for a summary), unlike for banking where there is a wide literature. We take an exploratory approach to address the question, applying benchmarks used in competition research to a unique set of reporting data across multiple UK insurance regulatory regimes, with the hope of stimulating further work. We find competition generally works well in UK life and non-life insurance markets, despite increases in life market concentration over the past 25 years. However, competition regulators have found practices in specific markets that harm consumers.
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 August 1914, Britain was the world’s wealthiest country. Yet there was no guarantee that government would be able to harness that wealth for World War I. Effectively, Britain was forced into a ‘Battle for Capital’ simultaneous with its military efforts — with the efficacy of the latter dependent on the success of the former. Over 80% of the £7,280 million Britain borrowed from 1914 to 1919, was raised at home. New research shows that Britain’s desperate efforts to marshal its citizens’ capital for the purpose of war, while also struggling to direct wartime production, profits and labour, led to a sharp shift in the sources of its borrowings during the war and in the years after.
Data plays a central role in all technical aspects of insurance and actuarial work. However, utilisation is often still confined to aggregate premium and claims data. Not so in the case of telematics. Say the phrase ‘black box’ and most people will think of flight recorders fitted to aircraft. But Motor insurers also use the millions of data points generated by black boxes, fitted to more than a million cars in the UK, to price risks. What’s more Marine insurers are getting in on the act. In this post we take an actuarial vantage to explore the use of telematics data and consider whether insurers could be using this ‘gold mine’ of information even more widely.

Understanding gross capital flows is crucial for both macroeconomic and financial stability policy. However, theory is lagging behind empirical work, as much of the literature continues to rely on net capital flow models developed many decades ago. Missing from these models is an explicit tracking of the financial records underlying all goods and asset purchases, namely gross balance sheet positions, which in turn requires modelling the principal medium of exchange, bank deposits. Our new model features gross capital flows and offers a fresh perspective on important policy debates, such as the role of current accounts as indicators of financial fragility, the nature of the global saving glut, Triffin’s current account dilemma, and the synchronisation of gross capital inflows and outflows.
