Structural Pricing of CoCos and Deposit Insurance with Regime Switching and Jumps

Abstract

In this article, we construct a structural model with jumps and regime switching to price banks' contingent convertible debt (CoCos) and deposit insurance. We use an Esscher transform that is applicable to regime switching double exponential jump diffusions to move from the historical world to the risk-neutral world. Further, we define and implement a matrix Wiener-Hopf factorization associated with the latter processes, allowing us to price the various components of a bank's balance sheet. Thus, we obtain valuation formulas for the bank's equity, debt, deposits, CoCos, and deposit insurance. We also show in an illustration the respective effects of the jump risk and of regime switching on the values of all of a bank's balance sheet components.
