Global supply and demand refer to the total amount of goods and services available in the world (supply) and the desire of consumers to purchase them (demand). When supply exceeds demand, prices tend to fall, while prices rise when demand outstrips supply. This balance is crucial for economic stability and growth. Factors such as population growth, consumer preferences, and technological advancements can influence global supply and demand. For instance, an increase in online shopping can boost demand for certain products, while natural disasters may disrupt supply chains, affecting availability and pricing worldwide.
