Term supply shock Definition: A disruption of market equilibrium (that is, a market adjustment) caused by a change in a supply determinant and a shift of the supply curve. A supply shock can take one of two forms--an supply increase or a supply decrease. An increase in supply is illustrated by a rightward shift of the supply curve and results in an increase in equilibrium quantity and a decrease in equilibrium price. A decrease in supply is illustrated by a leftward shift of the supply curve and results in a decrease in equilibrium quantity and an increase in equilibrium price.
