We are living in a world in which banks are large relative to the economies they serve. This column uses comprehensive data on Japanese banks from 1990 to 2010 to examine how the fates of individual banks matter for aggregate performance. Much of the fluctuation in Japanese aggregate investment appears to be driven by the idiosyncratic successes and failures of a limited number of institutions, and there is good reason to believe that the situation is similar in many developed countries.

Banks' payout decisions at the beginning of the financial crisis of 2007-2009 were particularly controversial as the crisis eroded the capital of many banks. Concerns were raised that banks may have engaged in wealth transfer to shareholders, or that they may have been reluctant to reduce dividends to avoid negative signalling. This column examines these arguments using a large dataset on US bank holding companies. Cross-sectional tests do not provide clear-cut evidence of active wealth transfer. Similarly, the evidence on signalling is mixed.

Many policies have been put in place to constrain the expansion of banks across economic borders, in part to avoid them becoming too big and interconnected to fail. However, some argue that such expansion can reduce risk. This column evaluates the impact of geographic expansion on the cost of a bank’s interest-bearing liabilities. Geographic diversification materially lowers bank holding companies’ funding costs, suggesting there is a real cost of restricting banks from using geographic expansion to diversify their risks.

Governments and regulators are commonly assumed to offer special protection to the stakeholders of large financial institutions during financial crises. This column measures the ex ante cost of implicit shareholder guarantees to financial institutions in crises, and suggests that such protection affects small and large financial institutions differently. The evidence suggests that in the event of a financial crisis, stock investors price in the implicit government guarantees extended to large financial institutions, but not to small ones.

Some economists are approaching a consensus that the Eurozone’s financial architecture is now resilient enough to withstand another shock similar to that of 2010-11. This column argues that such a view may be overly optimistic. Economic and financial instability persists in member states and the banking sector, and institutions to tackle a shock remain incomplete. While the Eurozone remains vulnerable to a bad shock, the blanket application of burden sharing without consideration of current economic and financial conditions is unwise.

Recent research into how monetary policy frameworks incorporate risks to financial stability has shown that policy affects both financial conditions and financial vulnerabilities that amplify negative shocks. This column argues that looser monetary policy improves financial conditions, but can in some situations worsen vulnerabilities through incentives for financial sector risk-taking and non-financial sector borrowing. Policymakers face an intertemporal trade-off between financial conditions and vulnerabilities which may impact a cost-benefit analysis of monetary policy.

The recession has left a legacy of non-performing loans on Italian banks’ balance sheets. Policymakers in Italy understand well the importance of correcting their banks’ problems to foster a healthy economic recovery. This column argues that reforming the judicial and extra judicial processes for recovering collateral offers the potential of improving banks’ balance sheets and enhancing financial stability, not only by increasing loan collections directly, but also by improving borrowers’ incentive to service their existing debt.

Negative shocks to bank balance sheets are problematic not just for financial markets, but for employment and economic growth more widely. This column uses evidence on a bank liquidity shock in Italy in 2007-10 to show the impact on firms’ production, investment, and employment. Firms borrowing from banks with a high exposure to the shock experienced a more intense fall both in credit flows and in investment expenditure. While the credit cut has been homogeneous across borrowers, firms with easier access to external finance were able to contain the negative consequences of the drop in credit for investment.
Banking is one of the most complex areas of modern economies. Flawed understanding, mismanagement, and bad regulation of banks have caused the Great Financial Crisis of 2007-2010 and the worst economic crisis in Europe in decades. This course will shed some light on the theory of banking and recent empirical insights into the functioning of banks. Starting from a thorough discussion of basic conceptual frameworks it will discuss elements of shadow banking, financial stability, and bank regulation.
The course provides an introduction to the conceptual foundations of banking and explores the workings of banks in modern economies, by looking at problems of credit intermediation, liquidity provision, maturity transformation, relationship lending, and bank competition.

The two main elements of bank industry oversight are regulation and supervision. This column provides a framework for thinking about supervision in relation to regulation. Using US data on supervisory hours spent, it finds evidence of economies of scale for bank size. Additionally, less risky banks receive substantially lower amounts of supervisory hours. The findings highlight that supervisors face resource constraints and trade-offs.

The US government’s ‘bailout of bankers’ in 2008-09 remains a highly controversial moment in economic policy. Many critics suggest that intervention to relieve household debt may have been more effective in stimulating economic recovery. This column suggests that without federal intervention to stabilise financial markets and recapitalise some non-bank lenders, the magnitude of the economic collapse might have been much worse. While household debt was incredibly important in reducing demand, the financial sector dislocations and the lack of credit also played a critical role.

There has been much research on the effects of banking crises, but corporate resilience to systemic crises is less well understood. This column uses data from 34 countries from 1990 to 2011 to analyse the role of social trust – societal expectations that people will behave honestly and cooperatively – in building corporate resilience. It finds that social trust facilitates access to trade credit, and dampens the harmful effects of crises on corporate profits and employment.

Liability insurance is a fundamental part of banking regulation of today, but despite being accepted as best practice now, it did not expand out of the US until the second half of the 20th century. This column discusses economic and political explanations for the spread of liability insurance availability, and finds that a political explanation reflects the empirical evidence well. Liability insurance was preferable to other policies despite being inefficient, due to its use as political leverage.

By creating liquidity, banks improve the allocation of capital and accelerate economic growth. This column uses evidence from US banks between 1984 and 2006 to evaluate the impact of competition amongst banks on their liquidity creation. It finds that an intensification of competition in the banking industry materially reduces liquidity creation. Furthermore, the evidence suggests that more profitable banks experience a smaller reduction in liquidity creation because of their ability to better absorb risk. Similarly, an intensification of competition reduces liquidity creation more among small banks, who are more engaged in relationship lending.

Since the Global Crisis, interest rates in many advanced economies have been low and, in many cases, are expected to remain low for some time. Low interest rates help economies recover and can enhance banks’ balance sheets and performance, but persistently low rates may also erode the profitability of banks if they are associated with lower net interest margins. This column uses new cross-country evidence to confirm that decreases in interest rates do indeed contribute to weaker net interest margins, with a greater adverse effect when rates are already low.

Since the Eurozone Crisis a host of monetary and fiscal instruments have been used to try to reinvigorate growth and achieve financial stability, with mixed results. Basel III’s counter-cyclical capital buffer (CCB) is one such instrument which was met with scepticism. This column uses evidence from the Swiss economy to show that given the right circumstances and political will, the CCB can achieve financial stability.

Business cycles are generally viewed as having been less correlated during the Bretton Woods period, 1950-1971. This column discusses findings from a new database of quarterly industrial production for 21 countries from 1950 to 2014 based on IMF archival data. As it turns out, business cycle synchronisation was as strong before 1971 as it was after (up till the Global Crisis began in 2007). Moreover, deeper financial integration tends to de-synchronise national outputs from the world cycle, at least in non-crisis periods.

In the absence of full information about small businesses’ risk of loan default, banks are unable to accurately calculate counterparty risk. This column suggests that banks can use industry and linked-industry data to better establish counterparty risk, because distress from one industry is transmitted to supplier and customer industries. A reliable and easily available signal for such distress is any failure reported by S&P.
The U.S. Great Recession has pointed to the importance of the banking sector in originating, amplifying, and propagating financial shocks to the real side of the economy. In response to the downturn, there has been a great deal of new regulation to mitigate the effects of future financial crises. Quantitative structural models of the banking sector that avoid the Lucas critique are critical to conduct counterfactual policy to evaluate the effects of new regulation. One important factor in the effects of policy is banking industry market structure and competition among banks of different sizes. Regulation itself may effect market structure and the distribution of bank size. Understanding regulatory arbitrage and how competitiveness of the banking sector varies with changes in regulation is critical to understand the health of the financial system.

Post-crisis banking is in trouble, with cross-border bank lending significantly slower than before. Many economists think that this is down to complications from government ownership. This column argues that although government ownership is not the only possible friction or reason for cross-border bank lending, it is an inhibitor of cross-border bank activity in both the UK and the US. If the same mechanism applies to other countries around the world, then global banking intermediation may rebound once again, once banks are privatised.
