There is little empirical evidence that specialised banks are less stable or perform worse, as suggested by standard portfolio diversification theory. This column uses new data to argue that more specialised banks between 2002 and 2012 did not perform as theory would suggest. More specialised banks, and banks with similar sectoral exposures to their peers, suffered less volatility and had lower exposure to systemic risk. The lack of post-crisis regulatory reform in this area may, accidentally, have been a good thing.

‘Too big to fail’ is an enduring problem for financial authorities and regulators. While forbidding government bailouts may be a popular move, the strategy lacks credibility. This column examines the proposals of the Minneapolis Plan to End Too Big to Fail. The plan has many virtues that tackle systemic problems and that build on the Dodd-Frank Act’s crisis prevention and management tools. However, further analysis of the plan is still needed to ensure that its measures aren’t circumvented.

Between 1870 and 1914, 68 countries – both sovereign and British colonies – used the London Stock Exchange to issue bonds. This column argues that bond prices and spreads in this period show that the colonies’ semi-sovereignty lowered credit risk at the price of higher illiquidity risk, and further worsened liquidity by attracting investors that rarely traded. Parallels between Eurozone and colonial bonds suggest that the pricing of liquidity and credit in government bond markets is an institutional phenomenon.

The Global Crisis has led to a new wave of regulation. This column argues that improved capital requirements, liquidity requirements, bank resolution and cross-border regulatory cooperation are welcome, but that unresolved problems remain. Specifically, regulation may become too complex, focus too little on macroprudential risks, be inadequate to deal with crises in global financial institutions, or fail to cope with financial innovation.

In the years preceding the Great Recession there was a dramatic rise in household debt in the US, and an increase in import competition triggered by the expansion of China and other low-wage countries. This column uses consumer credit data to argue that these phenomena are intimately linked. Household debt levels increased significantly in counties where US manufacturing jobs shifted overseas, and regional exposure to import competition explains 30% of the cross-regional variation in the growth in household debt.

Central banks responded to the financial crisis by cutting policy rates to prevent deflation and curb the decline in economic activity, but these responses have been anything but temporary. This column explores whether the sticky price channel is still relevant in an environment of persistently low rates. Although the effectiveness of the sticky price channel is limited, monetary policy instead transmits through mortgage debt. The recent period of low rates and low inflation has redistributed income and consumption from savers to mortgage borrowers.

Conventional economic theory predicts that, outside of a financial crisis, quantitative easing should have no effect on real outcomes or inflation. This column proposes two theoretical channels through which quantitative easing might also work in a fiscal crisis. In this case, quantitative easing can be a valuable tool because it can control the path of inflation over time and reduce the distortions to the credit flow in the economy.

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.

To mitigate the risks of international trade for firms, banks offer trade finance products – specifically, letters of credit and documentary collections. This column exploits new data from the SWIFT Institute to establish key facts on the use of these instruments in world trade. Letters of credit (documentary collections) cover 12.5% (1.7%) of world trade, or $2.3 trillion ($310 billion).

The volume of credit to Swedish households has grown twice as fast as incomes since the mid-1990s. This has resulted in both rising house prices and rising household debt. This column argues that these trends expose Sweden to important economic vulnerabilities. Curbing these vulnerabilities will require prompt action by the authorities.

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.

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.

The first century of modern Greek monetary history has striking parallels to the country’s current crisis, from repeated cycles of entry and exit from the dominant fixed exchange rate system, to government debt built-up and default, to financial supervision by West European countries. This column compares these two episodes in Greece’s monetary history and concludes that lasting monetary union membership can only be achieved if both monetary and fiscal policies are effectively delegated abroad. Understandable public resentment against ‘foreign intrusion’ might need to be weighed against their potential to secure the long-term political and economic objective of exchange rate stabilisation.

Information asymmetry is a key factor during financial crises. In this Vox Views video, Thomas Gehrig compares the 1907 and 2007 crises and finds common patterns. Information is a driver of crises and of market liquidity. In periods of stress, finding liquidity is difficult and illiquidity increases mostly because of information. 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.

Emerging markets face their fifth consecutive year of slowing growth. This column examines the nature of the slowdown and appropriate policy responses. Repeated downgrades in long-term growth expectations suggest that the slowdown might not be simply a pause, but the beginning of an era of weak growth for emerging markets. The countries concerned urgently need to put in place policies to address their cyclical and structural challenges and promote growth.

‘Helicopter tax credits’ have been proposed as a means of injecting new purchasing power into the economies of Eurozone Crisis countries. This column outlines one such system for Italy. The Tax Credit Certificate system is projected to accelerate Italy’s recovery over the next four years, and will likely be sustainable. It also provides a tool to avoid the breakup of the Eurosystem and its potentially disruptive consequences.

The Global Crisis renewed debate on the benefits and limitations of coordinating international macro policies. This column highlights the rare conditions that lead to international cooperation, along with the potential benefits for the global economy. In normal times, deeper macro cooperation among countries is associated with welfare gains of a second-order magnitude, making the odds of cooperation low. When bad tail events induce imminent and correlated threats of destabilised financial markets, the perceived losses have a first-order magnitude. The apprehension of these losses in times of peril may elicit rare and beneficial macro cooperation.

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.

From the introduction of the euro in 1999 to the Greek crisis in 2010, the Eurozone witnessed external imbalances between countries at its core and those at its periphery. These imbalances have been attributed either to differences in competitiveness or to the effect of financial integration. This column argues that in order to understand the imbalances within the Eurozone, it is necessary to consider credit costs and capital flows. The lower real cost of credit for high-inflation countries must be taken into account, as well as the inflow of capital to the non-tradable sector that this implies. Monetary policy cannot be conducted in a ‘one size fits all’ manner.
