The term over-supply suggests an excess of something, such as goods or resources. Its antonym, under-supply, describes a situation where there is a shortage or lack of something. For example, an under-supply of food could lead to hunger and malnutrition, while a shortage of medical supplies could lead to inadequate healthcare. Another antonym that can be used in the context of over-supply is equilibrium, which refers to a state of balance and stability where supply and demand are equal. Achieving equilibrium can be difficult, as it requires a careful balance of production, consumption, and distribution. Other antonyms of over-supply include scarcity, insufficiency, and deficit.
