A discrete‐time financial system is proposed by using forward Euler scheme. Based on explicit Neimark‐Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal form method and center manifold theory, the system′s existence, stability and direction of Neimark‐Sacker bifurcation are studied. Numerical simulations are employed to validate the main results of this work. Some comparison of bifurcation between the discrete‐time financial system and its continuous‐time system is given.
