Following Aleksandar Vučić’s resignation as president on September 27, 2026, Serbian law requires a presidential election no later than three months later, creating a firm December 27 deadline for voting. The acting president, Ana Brnabić, must issue the formal call with a 30-to-60-day campaign window, pointing to a latest announcement around November 27. The Student List’s October 25 parliamentary victory and the subsequent assembly formation process introduce procedural sequencing, yet the binding constitutional timeline remains the dominant factor shaping trader assessments of the call date. No other major institutional or political hurdles have emerged to alter these parameters.
