Reaching-for-yield--investors' propensity to buy riskier assets in order to achieve higher yields--is believed to be an important factor contributing to the credit cycle. This paper presents a detailed study of this phenomenon in the corporate bond market. We show that insurance companies, the largest institutional holders of corporate bonds, reach for yield in choosing their investments. Consistent with lower rated bonds bearing higher capital requirement, insurance firms' prefer to hold higher rated bonds. However, conditional on credit ratings, insurance portfolios are systematically biased toward higher yield, higher CDS bonds. Reaching-for-yield exists both in the primary and the secondary market, and is robust to a series of bond and issuer controls, including bond liquidity and duration, and issuer fixed effects. This behavior is related to the business cycle, being most pronounced during economic expansions. It is also more pronounced for firms with poor corporate governance and for which regulatory capital requirement is more binding. A comparison of the ex-post performance of bonds acquired by insurance companies shows no outperformance, but higher systematic risk and volatility.
