Hedge funds and their implications for financial stability

The paper provides an overview of the hedge fund industry, mainly from a financial stability and European angle. It is primarily based on an extensive analysis of information from the TASS database. On the positive side of the financial stability assessment, hedge funds have a role as providers of diversification and liquidity, and they contribute to the integration and completeness of financial markets. Possible negative effects occur through their impact on financial markets (e.g. via crowded trades) and financial institutions (e.g. via prime brokerage). Several initiatives have been launched to address these concerns and most of them follow indirect regulation via banks. If any direct regulation were to be considered, it would probably have to be implemented in a coordinated manner at the international level. At the EU level there is currently no common regulatory regime, although some Member States have adopted national legislation.Asset management, crowded trades, financial regulation, financial stability, hedgefunds, prime brokerage, risk management.

Short selling in extreme events

We study the association between daily changes in short selling activity and financial stock prices during extreme events using TailCoR, a measure of tail correlation. For the largest European and US banks, as well as European insurers, we uncover a strong relation during exceptional (extreme) days and a weak relation during normal (average) days. Examining days with large increases in short positions and large downfalls in stock prices, we find evidence of both momentum and contrarian short selling taking place. For North American bank stocks, contrarian short selling appears more practiced than for European bank and insurance stocks. We find that the uncovered relationship decreases with firm size and increases during ban periods, which is in line with short selling becoming more informative when constrained.This work was supported by the Communauté française de Belgique [grant number 13/17-055]

Fund Management and Systemic Risk - Lessons from the Global Financial Crisis

Fund managers play an important role in increasing efficiency and stability in financial markets. But research also indicates that fund management in certain circumstances may contribute to the buildup of systemic risk and severity of financial crises. The global financial crisis provided a number of new experiences on the contribution of fund managers to systemic risk. In this article, we focus on these lessons from the crisis. We distinguish between three sources of systemic risk in the financial system that may arise from fund management: insufficient credit risk transfer to fund managers; runs on funds that cause sudden reductions in funding to banks and other financial entities; and contagion through business ties between fund managers and their sponsors. Our discussion relates to the current intense debate on the role the so-called shadow banking system played in the global financial crisis. Several regulatory initiatives have been launched or suggested to reduce the systemic risk arising from non-bank financial entities, and we briefly discuss the likely impact of these on the sources of systemic risk outlined in the article

Short Selling in the Tails

Short selling plays a crucial role for price discovery and liquidity purposes yetnational governing authorities decided to ban short selling in periods of extreme pricemovements, on the grounds that short selling can exacerbate price downturns. Whereasmost of the literature analyses the average relation between short selling and pricechanges, our study focuses on the relation that occurs during extreme events, usinga new paradigm that stems from the literature on tail correlations. For the largestEuropean and US banks, as well as European insurers, we uncover a very strong relationwhen both variables are in their tails. In normal times, no negative association is found,which favours the view that short sellers act as price stabilizers. But during turmoil,short selling relates with excessive price drops that can put the market under seriousstress.info:eu-repo/semantics/publishe
