Kind regards, Youchang Wu Abstract In this paper we study the optimal design of credit derivative contracts when banks have private information over their loan portfolios and are subject to minimum regulatory capital requirements. We show that bank regulation affects the form of the optimal signalling contracts. Moreover we show that the use of signalling contracts is more costly when OTC credit derivative markets are opaque.
