  We investigate supersymmetric models in which an anomalous $U(1)_{X}$
symmetry explains the Yukawa hierarchy, and the related $D_{X}$-term plays a
role in supersymmetry breaking. We use a bottom-up approach to model building.
Phenomenological viability leads to a scenario with degenerate squark and
slepton spectra and with heavy gauginos. Features of a K\"ahler potential that
allows for such a scenario are described.
