In this paper we investigate the permanent of (-1,1)-matrices over fields of zero characteristics and our main goal is to provide a sharp upper bound for the value of the permanent of such matrices depending on matrix rank, solving Wang's problem posed in 1974 by confirming Kräuter conjecture formulated in 1985.
