Insurance Companies and the Growth of Corporate Loans' Securitization
Insurance companies nonupled their CLO investments in the post-crisis period. This growth has far outpaced that of loans and bonds and is characterized by a strong preference for mezzanine tranches over triple-A tranches. Conditional on capital charges, insurance companies invest more in bonds and CLO tranches with higher yields. Importantly, they prefer CLO tranches because these carry higher yields relative to bonds. Preferences increased following the 2010 capital regulatory reform, resulting in insurance companies holding 40 percent of outstanding mezzanine tranches. Insurance companies ...

Measuring Interest Rate Risk in the Life Insurance Sector: The U.S. and the U.K.
We use a two factor model of life insurer stock returns to measure interest rate risk at U.S. and U.K. insurers. Our estimates show that interest rate risk among U.S. life insurers increased as interest rates decreased to historically low levels in recent years. For life insurers in the U.K., in contrast, interest rate risk remained low during this time, roughly unchanged from what it was in the period prior to the financial crisis when long-term interest rates were in their usual historical ranges. We attribute these differences to the heavier use of products that combine guarantees with ...

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 ...

Investment Commonality across Insurance Companies : Fire Sale Risk and Corporate Yield Spreads
Insurance companies often follow highly correlated investment strategies. As major investors in corporate bonds, their investment commonalities subject investors to fire-sale risk when regulatory restrictions prompt widespread divestment of a bond following a rating downgrade. Reflective of fire-sale risk, clustering of insurance companies in a bond has significant explanatory power for yield spreads, controlling for liquidity, credit risk and other factors. The effect of fire-sale risk on bond yield spreads is more evident for bonds held to a greater extent by capital-constrained insurance ...

Over-the-Counter Market Liquidity and Securities Lending
This paper studies how over-the-counter market liquidity is affected by securities lending. We combine micro-data on corporate bond market trades with securities lending transactions and individual corporate bond holdings by U.S. insurance companies. Applying a difference-in-differences empirical strategy, we show that the shutdown of AIG's securities lending program in 2008 caused a statistically and economically significant reduction in the market liquidity of corporate bonds predominantly held by AIG. We also show that an important mechanism behind the decrease in corporate bond liquidity ...

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 ...

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, ...
