Asset Manager Commonality and Portfolio Similarity
Asset managers are increasingly influential in financial markets. We use new regulatory as well as manually collected data on asset managers of life insurers, the largest institutional investors of corporate bonds, and find that insurers with the same asset managers have more similar portfolios and trades. This similarity increases further if the asset manager actively oversees the majority of both insurers’ assets. Moreover, the effect intensifies the longer insurers share the same asset manager. Nevertheless, the effect is primarily driven by purchases rather than sales and the resulting ...

Extrapolating Long-Maturity Bond Yields for Financial Risk Measurement
Insurance companies and pension funds have liabilities far into the future and typically well beyond the longest maturity bonds trading in fixed-income markets. Such long-lived liabilities still need to be discounted, and yield curve extrapolations based on the information in observed yields can be used. We use dynamic Nelson-Siegel (DNS) yield curve models for extrapolating risk-free yield curves for Switzerland, Canada, France, and the U.S. We find slight biases in extrapolated long bond yields of a few basis points. In addition, the DNS model allows the generation of useful financial risk ...

Insurance Companies and the Growth of Corporate Loans' Securitization
CLOs have emerged as the fastest growing asset class in insurance companies' portfolios after the Global Financial Crisis. This was induced by insurers' capital regulation which treats CLO tranches the same as equally-rated corporate bonds, despite the former offering higher yields. Consequently, insurance companies developed a preference for CLOs over corporate bonds, which was strengthened by a 2010 regulatory reform. Insurers' CLO investments shaped the CLO market, influencing deal structures and fueling its rapid post-crisis growth. This expanded credit access for corporate borrowers, ...
With few firms advising life insurers, is financial stability at risk?
Despite asset managers playing an increasingly pivotal role in investment decisions—leading to more similar portfolios—analysis of life insurance firms and their advisers reveals a relatively small threat to financial stability.

A Retrospective on the Life Insurance Sector after the Failure of Silicon Valley Bank
Following the Silicon Valley Bank collapse, the stock prices of U.S banks fell amid concerns about the exposure of the banking sector to interest rate risk. Thus, between March 8 and March 15, 2023, the S&P 500 Bank index dropped 12.8 percent relative to S&P 500 returns (see right panel of the chart below). The stock prices of insurance companies tumbled as well, with the S&P 500 Insurance index losing 6.4 percent relative to S&P 500 returns over the same time interval (see the center panel below). Yet, insurance companies’ direct exposure to the three failed banks (Silicon Valley Bank, ...

Insurance Companies and the Growth of Corporate Loan Securitization
Collateralized loan obligation (CLO) issuances in the United States increased by a factor of thirteen between 2009 and 2019, with the volume of outstanding CLOs more than doubling to approach $647 billion by the end of that period. While researchers and policy makers have been investigating the impact of this growth on the cost and riskiness of corporate loans and the potential implications for financial stability, less attention has been paid to the drivers of this phenomenon. In this post, which is based on our recent paper, we shed light on the role that insurance companies have played in ...
