Rejigging financial regulation is in vogue. But, in the world of international finance, how well do different regulatory systems join up? This column argues that the US Dodd Frank Act and Basel III are, in part, incompatible and that harmonising them may lead to unintended consequences. The US ought to tread carefully here but should also try hard to maintain the spirit of better financial regulation.

A credible threat of failure is an integral part of any industry. But this does not always apply to banks as failure may result in unacceptable economic costs. As a result, unprecedented amounts of public money have been used to avert bank failure. This column explains why the subsidy arises, why it is a public policy concern, and how it can be quantified.

A recent op-ed by a former Goldman Sachs employee has led to an outcry over two important themes which came to the fore during the crisis, ie corporate culture and incentives. This column argues that neither regulation nor market forces has put either of these issues to rest. It adds that bank complexity and the too-big-to-fail policy both serve to undermine market discipline.

Excessive risk-taking by large banks was among the main causes of the 2008–09 financial crisis. This column argues that the antidote to excessive risk-taking should come from the elimination of the subsidies of the banking charter and the implicit promise of bailout in case of major losses, and the introduction of strong incentives for management and shareholders to preserve the capital of their bank. This requires deep changes in Basel prudential rules.

In the wake of the 2008 financial crisis, there has been burgeoning interest in macroprudential policy as an overarching framework to address the stability of the financial system as a whole rather than only its individual components. This column, based on a new dataset from 49 countries, shows that some macroprudential instruments are effective in reducing procyclicality in the financial system, and thus systemic risks.

The effective regulation of banks requires identification of systemically important financial institutions. This column discusses a method to estimate the capital that a financial firm would need to raise if we have another financial crisis. This measure of capital shortfall is based on publicly available information but is conceptually similar to the stress tests conducted by US and European regulators.

Since 2010, Eurozone countries have engaged in unprecedented rescue operations to avoid contagion from a potential Greek sovereign default. This column argues that news about Greek public finances does not affect Eurozone bank stock prices, while news about a Greek bailout does. This suggests that markets consider news about a Greek bailout to be a signal of Eurozone countries’ willingness to use public funds to combat the financial crisis.

Understanding credit crunches is a major concern for policymakers. This column suggests that the severity of a credit crunch in a specific area depends on the hierarchical structure of the banks operating in that credit market. It explores the Italian case and shows that, in the months following the collapse of Lehman Brothers, banks retracted disproportionally from markets that are more distant from their headquarters.

The global financial crisis has shown that neglecting liquidity risk comes at a substantial price. This column presents a new framework to run system-wide, balance sheet data–based liquidity stress tests. The liquidity framework includes a module to simulate the impact of bank-run type scenarios, a module to assess risks arising from maturity transformation and rollover risks, and a framework to link liquidity and solvency risks.

Throughout the European debt soap opera, Europe’s leaders have expressed their willingness to “do whatever it takes” to restore stability and save the euro. This column argues that, too often, policymakers have in fact been “doing whatever it takes” to serve the banks.

Despite emergency summits and last-minute reforms, there is still a large question mark hanging over the euro. This column argues that a chief cause of this is the management of Europe’s banks. It epitomises many of the contradictions at the heart of the Eurozone and unless resolved could be the cause of a slow and painful death of the single currency.

Vincent O'Sullivan, Stephen Kinsella, 17 December 2011

The capital shortfall at EU banks is 8% higher than originally thought, according to the latest assessment from the European Banking Authority. This column examines the evolution of loan-to-deposit ratios in big European banks. It says banks have been buying back their debt securities, hoarding profits, limiting bonuses, and deleveraging. However, write-downs of sovereign debt have largely offset these efforts.

The financial system is like an organ in the body of the economy. But is it the heart or the appendix? This column, part of the Vox Debate on whether we need a financial sector, argues that we should measure the value banks create through their management of risk, not simply their bearing of risk. Under this measure, banks may well be less valuable to the economy.

Damiano Sandri, Ashoka Mody, 23 November 2011

European policymakers are confronting a heightened crisis characterised by a perverse and seemingly intractable interplay between sovereign debt pressures and financial-sector fragilities. This column argues that the payoffs from strengthening banks’ balance-sheets can still be large and, therefore, fiscal support is merited. But a more resolute strategy for winding down banks is also needed.

Viral Acharya, Dirk Schoenmaker, Sascha Steffen, 22 November 2011

The lack of market confidence in European banks is fed by the uncertainty about Eurozone sovereign debt. This column argues governments and banking supervisors should agree a recapitalisation package well before Christmas. It adds that the required amount to be raised by each bank should be presented as a euro amount and not as a ratio so as not to tempt banks to cut down assets instead of raising capital.

Charles Goodhart, 30 August 2011

The calls for better bank regulation are many. This column argues that regulators have the concepts right, but the mechanisms are in need of repair.

Jon Danielsson, 27 June 2011

A debate is raging on capital adequacy requirements for banks. The UK wants to be allowed to “top up” the agreed levels, i.e. to impose stricter capital standards than the EU minimum. This column argues the UK is right, and that the German and French opposition might be motivated by weaknesses in their banking systems.

Crises are a regular event in financial markets. But do banks that have been hit particularly hard in one crisis learn from the experience and suffer less in future crises? This column suggests not. It shows that banks particularly hard hit by the 1998 financial crisis were also badly affected by the recent financial crisis. It blames the high-risk business models on which these banks rely.

Shekhar Aiyar, 12 May 2011

It is widely believed that banks played a central role in the Great Recession, but where is the smoking gun? This column presents evidence from the UK confirming the conventional wisdom. It finds that banks transmitted the unprecedented external funding shock by cutting back on domestic lending.

The authors of CEPR DP8333 assess the optimal level of equity for banks to hold, taking into account costs and benefits both private and social. After considering these overall economic (or social) costs, the authors conclude that desirable equity levels for banks are far higher than actual levels or even target levels under Basel III.
