In this work we introduce the notion of implied Core Equity Tier 1 volatility and the concept of a risk-adjusted distance to trigger. Using a derivatives-based valuation approach, we are able to derive the implied CET1 volatility from the market price of a CoCo bond in a Black-Scholes setting....

This article provides an in-depth analysis of the pricing and structuring of contingent convertibles (CoCos) with extension risk. Under the new regulatory Basel III framework, CoCo bonds can be categorised as either belonging to the Additional Tier 1 or Tier 2 capital category. The Tier 1 CoCo...

We introduce a novel sustainable capital instrument, with features inspired by CoCos: the skin-in-the-game bond. A skin-in-the-game bond is linked to the performance of a benchmark that relates to the broad concept of sustainability in at least one of its pillars: the environment, society or...

This paper presents a Heston-based pricing model for contingent convertible bonds (CoCos). The main finding is that skew in the implied volatility surface has a significant impact on the CoCo price. Hence stochastic volatility models, like the Heston model, which incorporate smile and skew are...

In this paper we introduce a new variant on the more traditional green climate bond. Green bonds are standard corporate bonds created to finance environmentally beneficial projects. The concept of a Reverse Green Bond is very similar to contingent convertibles (CoCos) issued by financial...

A green bond is a type of fixed-income security that raises money to invest in predetermined climate and environmental projects, in contrast to conventional debt instruments, where the use of proceeds is not specified in the terms. The difference in yield between a green bond and an otherwise...
