Commercial paper is one of the largest money market instruments and has long been viewed as a safe haven for investors seeking low risk. However, during the financial crisis of 2007-2009, the commercial paper market experienced twice the modern-day equivalent of a bank run with investors unwilling to refinance maturing commercial paper. We analyze the supply of and demand for commercial paper and show that, in contrast to previous turbulent episodes, the crisis centered on commercial paper issued by, or guaranteed by, financial institutions. We describe the importance of Federal Reserve’s interventions in restoring stability of the market. Finally, we propose three possible explanations for the sharp decline of the commercial paper market: substitution to alternative sources of financing by commercial paper issuers, adverse selection, and institutional constraints among money market funds.
