Hierarchical soft terms describe a class of supersymmetric theories in which the first two generations of squarks and sleptons are heavier than the rest of the supersymmetric spectrum. They make well-defined, interesting predictions as there are fewer free parameters than in the ordinary case of degenerate squarks and provide a characteristic correlation between Delta F = 1 and Delta F = 2 transitions. We study the constraints on the flavor-violating parameters and point out that values of the phase of B-s mixing larger than in the case of degenerate soft terms can be obtained
