In this talk I report calculable nonperturbative QCD effects to the inclusive semileptonic and radiative B-meson decay rates. Small instantons contribute to the Wilson coefficient functions at scales below mb. It is found that the instantons give rise to a potentially large correction to the decay rate near the boundaries of the phase space for the semileptonic decay case, but totally negligible for the radiative case. I explain how the difference may be understood as a simple consequence of different kinematics in the two cases.
