A demand shock is a sudden and unexpected change in the demand for goods or services within an economy, while the supply remains constant. These shocks can significantly disrupt market equilibrium, leading to price volatility and economic instability. The causes of demand shocks can vary, ranging from geopolitical events to sudden changes in consumer preferences.
