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.

Product market reforms are seen as a way to boost output in advanced economies, but we know little about their short-term impact. This column presents data from 18 advanced economies that reveal large differences in the potential upside of reform depending on the sector in which a firm operates, its size, and its financial health.

During political campaigns, candidates often set their sights on CEO compensation as a target for potential regulation. This column considers the various arguments for regulating CEO pay and questions whether it is a legitimate target for political intervention. Some arguments for regulation are shown to be erroneous, and some previous interventions are shown to have failed. While regulation can address the symptoms, only independent boards and large shareholders can solve the underlying problems.

The fragmentation of financial systems along national borders was one of the main handicaps of the Eurozone both prior to and in the initial phase of the crisis, hindering the shock absorption capacity of individual member states. The EU has taken important steps towards the deeper integration of Eurozone financial markets, but this remains incomplete. This column argues that a fully-fledged financial union can be an efficient economic shock absorber. Compared to the US, there is significant potential in terms of private cross-border risk sharing through the financial channel, more so than through fiscal (i.e. public) means.

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.

Growth in the number of publicly quoted companies is a key driver of economic development, so the apparent decline in the number of company listings, at least in developed markets, is naturally worrying for investors, exchanges, and regulators alike. This column provides a framework to address this decline, and proposes possible remedies that could be taken to encourage more listings. The listings ecosystem must establish a new equilibrium to address the evolving conflicts of interest between founders, early investors, underwriters, and future shareholders.

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 breakup of Bretton Woods in the early 1970s, the housing market has been at the centre of the biggest banking crises across the world. This column considers the nexus between housing, banking, and the economy, and how these ties can be broken. It argues for two modest regulatory changes in banking and insurance. These would result in life insurers and pension funds providing mortgage finance, better insulating the economy and homeowners from the housing cycle.

Current de jure measures of labour regulation stringency point to negative consequences of labour laws. This column presents new evidence on cross-country measurements of enforcement of labour laws from almost every country in the world. The authors argue that the consequences of labour enforcement cannot be credibly assessed using de jure measures which ignore the chance that enforcement is lower in places with stricter laws. On average, there is a negative correlation between the stringency of labour regulation and the intensity of its enforcement.

Following the Global Crisis, regulators around the world have shown a greater commitment to investigating and sanctioning corporate wrongdoers. This column argues that fines are only one (surprisingly small) component of the overall sanctions available to regulators. Reputational sanctions are, for some categories of misconduct, far more potent than direct penalties.

A combination of shocks has led to the spectre of a renewed systemic bank crisis within the EU. This column argues that what is needed is a regulatory policy response in the form of joint action by European governments to convince financial investors that bank liabilities are secure.

Prior to the Global Crisis, banks could easily use off-balance sheet structures to lower their effective capitalisation rates. This column examines another way that US banks circumvented capital regulations – by maintaining minority-owned, non-consolidated subsidiaries. Had these subsidiaries been consolidated, average reported equity-to-assets ratios would have been 3.5% lower. These findings suggest that some US banks were actively misrepresenting the riskiness of their assets prior to the crisis.

The Global Crisis revealed serious deficiencies in the supervision of financial institutions. In particular, regulators neglected organisational culture at the institutional level. This column reviews efforts since 2011 by De Nederlandsche Bank to oversee executive behaviour and cultures at financial institutions. These measures aimed at identifying risky behaviour and decision-making processes at a sufficiently early stage for appropriate countermeasures to be implemented. The findings show that regulators can play a larger part in securing the stability of the financial system by taking an active role in shaping institutional cultural processes.

There has always been conflict between macro- and microprudential regulation. Microprudential policy reigns supreme during good times, and macro during bad. This column explains that while the macro and micro objectives have always been present in regulatory design, their relative importance has varied according to the changing requirements of economic, financial and political cycles. The conflict between the two seems set to deepen and so, regardless of which ‘wins’, policymakers must not undermine the central bank's execution of monetary policy.

The long-running Greek crisis and China’s recent stock market crash are the latest threats to the stability of the global financial system. But as this column explains, systemic risk is an inevitable part of any market-based economy. While we won’t eliminate systemic risk entirely, the agenda for researchers and policymakers should be to create a more resilient financial system that is less prone to disastrous crises and that still delivers benefits for the economy and for society.

The Global Crisis has brought the ins and outs of bank stability to the attention of increasing numbers of academics and policymakers. But what is the impact of bank regulation and competition on bank opacity? This column presents one of the first evaluations of the impact of bank regulatory reforms on the quality of information disclosed by banks, which in turn helps us assess bank stability.

Debt financing amplifies the effects of asset prices fluctuations across the financial system and this can produce bubbles. Regulation therefore increasingly focusses on restricting debt financing. Although there is no silver bullet for making the financial system failure-proof, this column argues that policymakers should adopt an integrated and consistent macroprudential approach across the financial system in order to help prevent businesses moving to less-regulated pastures.

The 2007–08 crisis revealed regulatory failures that had allowed the shadow banking system and systemic risk to grow unchecked. This column evaluates recent proposals to reform the banking industry. Although appropriate pricing of risk should make activity restrictions redundant, there may nevertheless be complementarities between these two approaches. Ring-fencing may make banking groups more easily resolvable and therefore lower the cost of imposing market discipline.

The proposed EU capital markets union aims to revitalise Europe’s economy by creating efficient funding channels between providers of loanable funds and firms best placed to use them. This column argues that a successful union would deliver investment, innovation, and growth, but it depends on overcoming difficult regulatory challenges. A successful union would also change the nature of systemic risk in Europe.

Trillions of dollars’ worth of transactions depend on financial benchmarks such as LIBOR, but recent scandals have called their reliability into question. This column argues that reliable benchmarks reduce informational asymmetries between customers and dealers, thereby increasing the volume of socially beneficial trades. Indeed, the increase in trading volume may offset the reduction in profit margins, giving dealers who can coordinate an incentive to introduce benchmarks. The authors argue that benchmarks deserve strong and well-coordinated support by regulators around the world.
