Abstract
Large charge density, unlike high temperature, may lead to nonrestoration of global and gauge symmetries. Supersymmetric GUTs with the appealing scenario of unification scale being generated dynamically naturally contain global continuous symmetries. We point out that the presence of a large charge in the early Universe can lead to GUT symmetry nonrestoration. This provides a simple way out of the monopole problem.
