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.

In a global financial system, macroprudential policies may create international spillovers. This column presents new evidence on how the organisational structure of a bank affects the magnitude of these spillovers. An increase in capital requirements at home causes foreign branches to reduce their lending growth to other banks operating in the UK more than foreign subsidiaries do. Seemingly, this is because branches are an integral part of the parent company.

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.

Bank resolution is a key pillar of the European Banking Union. This column argues that the current structure of large EU banks is not conducive to an effective and unbiased resolution procedure. The authors would require systemically important banks to reorganise into a ‘holding company’ structure, where the parent company holds unsecured term debt sufficient to cover losses at its operating financial subsidiaries. This would facilitate a ‘single point of entry’ resolution procedure, minimising the risk of creditor runs and destructive ring-fencing by national regulators.

Recent experience with the zero lower bound on nominal interest rates, and the use of high-denomination notes by criminals and tax evaders, have led to revived proposals to phase out cash. This column argues that abolishing cash may be neither necessary nor sufficient to overcome the zero lower bound problem, and would severely undermine privacy. Allowing the public to hold reserves at central banks could reduce the need for deposit insurance, although the transition to the new regime and the effects on credit supply must be carefully considered.

Banking has recently proven much more fragile than expected. This column argues that the Basel III regulatory response overlooks the interactions between different kinds of prudential policies, and the link between prudential policy and competition policy. Capital and liquidity requirements are partially substitutable, so an increase in one requirement should generally be accompanied by a decrease in the other. Increased competitive pressure calls for tighter solvency requirements, whereas increased disclosure requirements or the introduction of public signals may require tighter liquidity requirements.

Eurozone financial integration is reversing, with 2013 cross-border capital flows at 40% of their 2007 level. This column discusses research showing that banking integration has in fact strengthened in the rest of the world.

Sound corporate governance is essential for a well-functioning banking system and the integrity of financial markets. This column discusses the corporate governance of Italian banks, its regulatory framework, and the specific challenges arising from the role played by foundations and large cooperatives. Although Italian banks have recently made progress in improving their corporate governance, more needs to be done.

Having completed the regulatory framework for systemically important banks, the Financial Stability Board is turning to insurance companies. The emerging framework for insurers closely resembles that for banks, culminating in the design and calibration of capital surcharges. This column argues that the contrasting business models and balance sheet structures of insurers and banks – and the different roles of capital, leverage, and risk absorption in the two sectors – mean that the banking model of capital cannot be applied to insurance. Tools other than capital surcharges may be more appropriate to address possible concerns of systemic risk.

Following the financial crisis, European banks have taken steps to revise unsustainable business models by deleveraging. By this metric they have made substantial progress – but this column argues that improper management of the deleveraging process may threaten the recovery. The authors find that equity increases played a much larger role than asset decreases, and recommend increasing the disposal of bad assets.

Following the Global Crisis the focus has been on how to make banks safer. Capital and liquidity requirements have been tightened, but attention now needs to shift to corporate governance and risk culture. This column argues that in opaque organisations, formal risk-appetite frameworks can provide a pre-commitment mechanism that tightens risk governance, but a focus on the wider risk culture is also important.

Individuals who work in the finance sector enjoy a significant wage advantage. This column considers three explanations: rent sharing, skill intensity, and task-biased technological change. The UK evidence suggests that rent sharing is the key. The rising premium could then be due to changes in regulation and the increasing complexity of financial products creating more asymmetric information.

The prevailing view of shadow banking is that it is all about regulatory arbitrage – evading capital requirements and exploiting ‘too big to fail’. This column focuses instead on the tradeoff between economic growth and financial stability. Shadow banking transforms risky, illiquid assets into securities that are – in good times, at least – treated like money. This alleviates the shortage of safe assets, thereby stimulating growth. However, this process builds up fragility, and can exacerbate the depth of the bust when the liquidity of shadow banking securities evaporates.

Four years ago, the Volcker Rule was codified as part of the Dodd–Frank Act in an attempt to separate allegedly risky trading activities from commercial banking. This column presents new evidence finding that those banks most affected by the Volcker Rule have indeed reduced their trading books much more than others. However, there are no corresponding effects on risk-taking – if anything, affected banks take more risks and use their trading accounts less for hedging.

There is growing concern – but little systematic evidence – about the relationship between sovereign default and banking crises. This column documents the link between public default, bank bondholdings, and bank loans. Banks hold many public bonds in normal times (on average 9% of their assets), particularly in less financially developed countries. During sovereign defaults, banks increase their exposure to public bonds – especially large banks, and when expected bond returns are high. At the bank level, bondholdings correlate negatively with subsequent lending during sovereign defaults.

Large banks have grown and become more involved in market-based activities since the late 1990s. This column presents evidence that large banks receive too-big-to-fail subsidies and create systemic risk, whereas economies of scale in banking are modest. Hence, some large banks may be ‘too large’ from a social perspective. Since the optimal bank size is unknown, the best policies are capital surcharges and better bank resolution and governance.

To date, much uncertainty exists about how large the spillovers would be from the default of a systemically important bank. This column shows evidence that the market values of US and EU banks hardly respond to changes in the default risk of banks that the Financial Stability Board considers globally systemically important (G-SIBs). However, changes in all G-SIBs’ default risk explain a substantial part of changes in bank market values. These findings have implications for financial-crisis management and prevention policies.

Cross-border funding between banks collapsed following the bankruptcy of Lehman Brothers, but the withdrawal of funding was not uniform across countries. This column argues that the composition of cross-border bank-to-bank funding can help to explain why. Interbank funding between unrelated banks is particularly vulnerable to global shocks, but intragroup funding between related banks can act as a stabilising force, particularly for advanced economies with a high share of global parent banks. Policymakers should look at disaggregated cross-border bank-to-bank flows, as doing otherwise could result in a misleading assessment of financial stability risks.

Contagious bank runs are an important source of systemic risk. However, with observational data it is near-impossible to disentangle the contagion of bank runs from other potential causes of correlated deposit withdrawals across banks. This column discusses an experimental investigation of the mechanisms behind contagion. The authors find that panic-based deposit withdrawals can be strongly contagious across banks, but only if depositors know that the banks are economically related.

The impact of tighter regulatory capital requirements during an economic upswing is a key question in macroprudential policy. This column discusses research suggesting that an increase of 15 basis points in aggregate capital ratios of banks operating in the UK is associated with a median reduction of around 1.4% in the level of lending after 16 quarters. The impact on quarterly GDP growth is statistically insignificant, a result that is consistent with firms substituting away from bank credit and towards that supplied via bond markets.
