We study the redistribution of quantum steering and its monogamy in the presence of the four-dimensional Kerr-Newman black hole. It is shown that the gravitational effect of the Kerr-Newman black hole can generate genuine tripartite steering between causally disconnected regions, which depends on the polar angle, angular momentum, electric charge, and magnetic charge of the black hole. We obtain the strong evidence of steering monogamy: the ``sudden death" of the $A$ $\rightarrow$ $B$ steering results in the ``sudden birth" of the $\bar{B}$ $\rightarrow$ $B$ steering. We also obtain the condition of maximal steering asymmetry: $\eta_{0}=\rm{arccosh}$$\sqrt{1+\tanh^{2}(s)}$, showing the transition between two-way steering and one-way steering in Kerr-Newman spacetime.
