Demand is a measure of consumer’s desire to purchase goods and services. High demand for a product typically puts upward pressure on price, and vice versa.
Demand is a key metric in reading price trends and a company’s ability to set price point. Weaker demand on a global macro level implies that countries are investing less, developing less, and therefore focused less on growth.
Sustained downtrends in demand will generally lead to recessionary conditions. Often times, central banks will try to step-in and stoke demand by lowering the cost of money (interest rates).
