Abstract: This paper revisits the impact of OBS activities on Canadian banks risk-return trade-off. Recent studies (Stiroh and Rumble 2006, Calmès and Liu 2007) suggest that increasing OBS activities do not necessarily yield straightforward diversification benefits. However, adding a risk premium to earlier accounting returns models by resorting to an ARCH-M procedure, an updated sample reveals that the Canadian banks risk-return trade-off displays a structural break, around 1997. In the second subperiod (1997-2007) of our sample, we find that the share of noninterest income no longer negatively impacts banks returns. Relatedly, we find that a risk premium emerges while, in the first period (1988-1996), the volatility variable is not significant in any returns equations. Our results are thus consistent with a maturation process story.
