Banks’ Risk Exposures

Since the financial crisis, there has been renewed interest in documenting how much risk financial institutions are exposed to. This paper shares the important goal of that scholarship: to come up with a method that summarizes banks’ positions in a meaningful way so that it will inform the theoretical modeling of these institutions and offer insights for policy decisions. Specifically, the paper measures banks’ exposures to macroeconomic risk through their fixed income positions by representing those positions in terms of simple factor portfolios. Factor portfolios provide measures of exposure that are easy to interpret and compare across positions. The results help elucidate the evolution of bank risk taking over the last 20 years.
