In this work, we propose an economical hybrid inflation model where the SM Higgs acts as a waterfall field, instead of the inflaton as proposed in the Higgs inflation models. In this model, the inflaton is an axion-like field which can trigger the electroweak symmetry breaking, while the backreaction of the Higgs field helps to terminate the process of inflation. Both cosmological and collider bounds and constraints are analyzed, and it is found that the model can work quite well to interpret the recent CMB data and the Higgs data from the LHC.
