Abstract:
This paper revisits the impact of off-balance-sheet (OBS) activities on banks risk-return trade-off. Recent studies (e.g., Stiroh and Rumble 2006) suggest that increasing OBS activities do not necessarily yield straightforward diversification benefits for banks. However, introducing a risk premium in the standard banks returns models, and resorting to an ARCH-M procedure, Canadian data suggest that banks risk-return trade-off displays a structural break around 1997. In the second subperiod of our sample (1997-2007), we find that the noninterest income generated by OBS activities no longer impacts banks returns negatively. While during the first period (1988-1996) the volatility variable is not significant in any returns equations, a risk premium eventually emerged, pricing the risk associated to OBS activities risks.
