Bank-to-bank lending in the euro area has increased, direct cross-border lending has not. The column shows that dependence on domestic banks reduces risk-sharing in a crisis, reducing GDP growth in affected country-sectors. Benefits from banking integration are only robust to global shocks if banking integration takes the form of cross-border lending to firms and households.

Risk taking was pervasive during the Global Crisis even in the most unlikely areas, such as stretching to lend at a distance. Using US data, this column examines the degree to which competition amongst lenders interacts with the cyclicality in lending standards using a simple and policy-relevant measure, the average physical distance of borrowers from banks’ branches. It finds that distances widen considerably when credit conditions are lax and shorten considerably when credit conditions become tighter. A sharp departure from the trend in distance between banks and borrowers is indicative of increased risk taking.

Emerging markets are especially vulnerable to a myriad of domestic and external risks. This column develops a framework to classify these risks based on their predictability and, hence, their insurability. As the probability of relatively large events increases, it becomes more difficult to insure against such risks. In the extreme case in which countries face truly unpredictable and impactful events (or ‘black swans’), they must rely on building broad-based resilience or resorting to ex-post aid.

Morten Ravn of University College London discusses ADEMU work on how differences across households and players in the economy matter for macroeconomic policy.

Investors fret that Italy may exit the euro. One reason to worry is redenomination risk, driven by the prospect of a country allowing a new currency to depreciate against the euro. This column compares two types of Italian bond yield curves to estimate such risk, and finds that the yield premium due to it peaked at 7% during the sovereign debt crisis. Redenomination risk also affects interest rates in strong economies, which implies a redistribution between savers and borrowers throughout the euro area.

Hélène Rey, Professor of Economics at London Business School and CEPR Fellow, explains how credit booms develop, what their mechanics are and how the financial intermediaries involved take on different amounts of risk.

The housing market faces major challenges in both the short and long run in terms of affordability, price variability, ownership structures, financing, and their impacts upon wider macroeconomic stability. This column summarises a conference on lessons for the future of housing, jointly organised by the Brevan Howard Centre for Financial Analysis at Imperial College Business School and CEPR.

The post-crisis period has seen a considerable shift in drivers of international bank lending and international bond issuance, the two main components of global liquidity. This column describes how the sensitivity of cross-border lending to global risk conditions declined substantially post-crisis, becoming similar to that of international bond issuance. This fall largely reflects a change in the composition of international lenders.

The share of fund assets held in exchange-traded funds has risen from 3.5% in 2005 to 14% in 2017, and to 20% for funds in emerging market assets. This column uses reported investor flows to argue that this is related to increased exposure of aggregate portfolio equity capital inflows to global risk. On this evidence, exchange-traded fund flows amplify the global financial cycle.

Risk weights define each bank's minimum capital requirements, but many doubt the comparability of the risk weights that banks report. This column quantifies the variability of these weights across banks, and finds that the country where a bank is headquartered creates statistically significant and economically important differences. Model output floors, as recently agreed upon by the Basel Committee, would reduce this unintended risk weight heterogeneity.

Global investors are assumed to differentiate between economies using economic fundamentals. This column uses returns on sovereign CDS contracts for 18 emerging markets and ten advanced countries to argue that fundamentals do not drive these decisions. Instead, most of the variation across sovereigns reflects whether or not the country is designated as an 'emerging market'. Investment strategies tend simply to replicate benchmark portfolios.

Syndicated loan issuance has grown dramatically over the last 25 years. Over the period, the syndicated loan business model has evolved, affecting the nature of the associated risks that arranging banks are exposed to. This column introduces the concept of ‘pipeline’ risk –the risk associated with marketing the loans during the syndication process. Pipeline risk forces arranging banks to hold much larger shares of very risky syndicated term loans, which results in reduced lending by the arran­­ging bank not only in the syndicated term loan market, but in others as well.

Interest rates continue to decline across the globe, while returns to capital remain constant or increasing. The reasons for this widening risky-safe gap are wide-ranging. This column illustrates the secular rise of risk intolerance in the global economy, and summarises a new macroeconomic framework suitable for this environment. It uses this framework to discuss the current global macroeconomic context, its underlying fragility, and the coexistence of low equilibrium interest rates and high speculation.

Since 2011, the Financial Stability Board (FSB) has implemented compensation principles and standards for executives and material risk-takers in many financial institutions. This column presents evidence that banks in jurisdictions that adopted them changed their compensation policies more than other banks. Compensation in these banks is less linked to short-term profits and more linked to risk, and the CEOs of risky banks now receive less in bonuses and other variable compensation than their peers at less risky banks.

Differences in attitudes to competition or risk may contribute to explaining gender gaps in wages and other labour market outcomes. This column analyses performance data from speedboat races in Japan revealing that women tend to race more slowly against men than against other women only, while men are faster in mixed-sex races. This finding may be driven by the skewed gender balance towards men in mixed-sex races triggering awareness of gender identity for both men and women, with implications for other activities in which men and women compete and women are outnumbered, such as the STEM disciplines.

Investing in stocks instead of bonds is risky. In this video, Paul Whelan discusses the importance of expected inflation. This video was recorded at the Brevan Howard Centre for Financial Analysis in December 2016.

Anomalies have returns above risk factors. In this video, Söhnke Bartram discusses three reasons why anomalies exist, and their implications. This video was recorded at the Brevan Howard Center for Financial Analysis in December 2016.

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.

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.
