Major international financial institutions (FIs) are using contingent convertible (CoCo) bonds in the wake of the 2008 financial crisis to meet stricter national and international capital requirements. Beginning with UniCredit’s €500m 9.375% CoCo in July 2010, more than 40 publically held financial institutions headquartered in 16 countries have issued 68 CoCos. This paper examines investors’ reactions to the announcements of CoCo bonds issuances by FIs. Using event-study methodology and measuring cumulative abnormal returns (CARs) following the announcements, we find FIs generally experience negative abnormal returns during the post-announcement period; however, the investors’ reactions vary in a country-by-country analysis. These different reactions allow the potential for investors to launch global diversification and trading strategies.
