CoCo Bonds and Risk: The Market View

File pdf 280KB

This paper investigates the impact of CoCo bond design on their market prices. Focusing on two CoCo bond features which are associated with CoCo risk, I find that (1) investors are aware of the incentive problem created in write down CoCo bonds, and demand a yield premium for that feature. Additionally, and consistent with the theory on moral hazard, this premium is higher for banks which suffer from a larger conflict of interest in the first place. Moreover, I find that (2) investors take the threat of automatic CoCo capital triggers seriously, in the sense that they reward a larger buer towards the trigger threshold with a higher price. These insights provide important clues towards the role of CoCo bond investors' monitoring, as well as the role of CoCo bonds in the mix of regulatory capital.
