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.

Much of the damage from the Great Recession is attributed to the Federal Reserve’s failure to rescue Lehman Brothers when it hit troubled waters in September 2008. It has been argued that the Fed’s decision was based on legal constraints. This column questions that view, arguing that the Fed did have the legal authority to save Lehman, but it did not do so due to political considerations.

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.

The categorisation of countries into relevant international benchmark indices affects the allocation of capital across borders. The reallocation of countries from one index to another affects not only capital flows into and out of that country, but also the countries it shares indices with. This column explains the channels through which international equity and bond market indices affect asset allocations, capital flows, and asset prices across countries. An understanding of these channels is important in preventing a widening share of capital flows being impacted by benchmark effects.

In the context of increased global trade and accompanying competition, firms are increasingly engaged in industrial clusters. This column uses firm-level transaction data to analyse the impact of firms’ relationships with financial institutions on their networking within clusters. Firms participating in government-supported cluster programmes increase their transaction networks significantly faster than those not in clusters. The column also finds that firms with expanding networks are mainly financed by regional banks, not national or global ones.

In April 2016, Italian banks set up an equity fund intended to recapitalise troubled financial institutions in a ‘private bail-out intervention’ scenario, with a view to avoiding a bail-in under the European Bank and Recovery Resolution directive. This column analyses the main differences between a bail-in and a bail-out scenario. In particular, it compares contagion effects, and thus the total default probabilities of financial institutions in these two circumstances, in order to establish which banks would benefit more from a bail-out rather than a bail-in.

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.

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.

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.

The Global Crisis emphasised the fragility of international financial networks. Despite this, there has been little historical research into how networks propagate financial shocks. This column explores how interbank networks transmitted liquidity shocks through the US banking system during the Great Depression. During banking panics, the pyramided-structure of reserves forced troubled banks to reduce lending, thus amplifying the decline in investment spending.

During normal operations, price discovery is an important feature of decentralised market trading. But the process can be distorted when markets are under great stress, such as during the run up to the collapse of Lehman Brothers in 2008. This column uses trading data from the days leading up to and following the collapse to show that price discovery at US stock exchanges remained remarkably efficient, even at the height of the turmoil.

Banks' balance sheets are complicated and opaque, making it hard to assess their health. In this Vox Views video, Maryam Farboodi suggests that opacity is an intentional choice by banks. Banks want to maximise their profits by offering the lowest return possible to investors without scaring them away. They choose to provide just enough information to maximise profits. The video was recorded in April 2016 at the First Annual Spring Symposium on Financial Economics organised by CEPR and the Brevan Howard Centre at Imperial College.

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 default of key financial intermediaries like Lehmann Brothers, as well as the global banking panic following the 2007-2008 financial crises, set in motion the path for a fundamental restructuring of the global financial architecture. This column argues that the most pressing question has been how to design an efficient mechanism for resolution of significantly important banks. Bail-in, as opposed to bailout, has been the worldwide solution. But this presents issues for global banks, which must adhere to the rules in many different jurisdictions.

Screening loan applicants is a key principle of sound banking, but it can be challenging when trustworthy information about applicants is not available. Many countries have therefore introduced credit registries that require banks to share borrower information. This column examines how the introduction of a new registry affected the functioning of the credit market in Bosnia and Herzegovina. Mandatory information sharing allowed loan officers to lend more conservatively at both the extensive and intensive margins. The improved credit allocation improved loan quality and lender profitability.

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.

Economists continue to debate whether preferential treatment in financial regulation increases banks’ demand for government bonds. This column looks at bank purchases of government bonds and other types of bonds when constrained by a capital or liquidity requirement. Financial regulation seems to be a main driver of banks’ demand. If regulators wish to break the vicious circle from weak banks to weak governments, revising financial regulation seems to be a good starting point.

In the years running up to the global crisis, the banking sector was marked by a high degree of leverage. Using US data, this column shows how, before the onset of the crisis, banks accumulated leverage both on and, especially, off their balance sheets. The latter activities saw an increase in maturity mismatch, raised the probability of bank runs, and increased both individual bank risk and systemic risk. These findings support the imposition of an explicit off-balance sheet leverage ratio in future regulatory frameworks.

As the recent Financial Stability Board decision on loss-absorbing capital shows, repairing the financial system is still a work in progress. This column reviews the author’s new book on the matter, Reinventing Financial Regulation: A Blueprint for Overcoming Systemic Risks. It argues that financial institutions should be required to put up capital against the mismatch between each type of risk they hold and their natural capacity to hold that type of risk.

In the lead up to the global financial crisis, there was a substantial credit boom in advanced economies. In the Eurozone, cross-border flows played an especially important role in the boom-bust cycle. This column examines how the common currency and linkages between member states contributed to the Eurozone crisis. A very strong relationship between pre-crisis levels of external imbalances and macroeconomic performance since 2008 is observed. The findings point to the importance of delinking banks and sovereigns, and the need for macro-financial policies that manage the risks associated with excessive international debt flows.
