Transparency in the interbank market and the volume of bank intermediated loans

In the present paper we study the equilibrium interaction through which the interbank market is related to the public lending and borrowing market. It turns out that this interaction is affected by the transparency in the interbank market. Interbank market transparency is modeled by means of more informative signals about future interbank rates. We find that more transparency might increase or decrease the volume of bank intermediated loans in the public market. In particular, the impact of more transparency on the volume of loans depends on the curvature of the marginal cost function of the banking firm. Furthermore, we find that expected profits of the bank are higher when the interbank market is more transparent.
