This thesis analyzes a new form of hybrid instruments used to enhance banks’ loss-absorption capacity, namely, convertible contingent bonds (CoCos). Specifically, it studies the effect of these issues in the credit ratings of banks. In greater details, the thesis describes CoCo characteristics and their contribution to the regulatory capital. Then it reviews the literature on bank credit ratings and their determinants. Lastly, in the empirical section it combines the aforementioned two strands of the literature with financial intermediation theory, to explore whether CoCo issuance is associated with credit-rating upgrade of the issuing banks. The results confirm this expectation.
