When demand curve intersects the supply curve.
A surplus of goods occur
In a perfectly competitive market, all sellers can find buyers in equilibrium as prices adjust to reflect supply and demand. When the market reaches equilibrium, the quantity supplied matches the quantity demanded, allowing transactions to occur. However, in real-world scenarios, factors such as market imperfections, information asymmetries, and externalities can prevent some sellers from finding buyers. Thus, while equilibrium facilitates transactions, it doesn't guarantee that all sellers will always find buyers.
When the price line is below the equilibrium point, there will be a shortage in the market, as the quantity demanded will exceed the quantity supplied at that price level. This imbalance prompts sellers to raise prices due to increased competition among buyers. As prices rise, the quantity demanded typically decreases while the quantity supplied increases until the market reaches equilibrium again.
When demand equals supply.
The quantity supplied in a market at some specific price must be less than the quantity demanded for a shortage to occur.

In a market system, price fluctuations must occur for quantity demanded to continually be equated with quantity supplied.
Surpluses occur when the quantity of a good or service supplied exceeds the quantity demanded at a specific price level. This situation typically arises when prices are set above the equilibrium price, leading to excess supply in the market. Surpluses can also occur due to factors such as increased production, decreased consumer demand, or external economic conditions. To address surpluses, prices may need to be lowered to encourage consumption and restore market balance.
Disequilibrium price refers to a situation in a market where the price of a good or service does not equal the level at which supply and demand are balanced. This can occur when the price is set too high, leading to excess supply (surplus), or too low, resulting in excess demand (shortage). In such cases, market forces typically drive the price towards equilibrium, where quantity supplied equals quantity demanded.
Surpluses and shortages are examples of disequilibrium because they occur when the quantity supplied does not equal the quantity demanded at a given price. A surplus arises when supply exceeds demand, leading to excess inventory, while a shortage occurs when demand surpasses supply, resulting in unmet consumer needs. Both situations indicate that the market is not in a state of balance, prompting adjustments in price or quantity to restore equilibrium. Ultimately, these imbalances signal the need for market corrections to align supply and demand.
Excess supply occurs when, at a given time, the equilibrium price of the market is less than the price that the goods are supplied at.
Consumer surplus under a monopoly is the difference between what consumers are willing to pay for a good or service and what they actually pay. In a monopolistic market, the monopolist typically sets a higher price and produces a lower quantity than would occur in a competitive market, leading to a reduction in consumer surplus. The monopoly's market power allows it to capture more of the total surplus as profit, resulting in a deadweight loss and less overall welfare for consumers. Consequently, consumer surplus is generally lower in a monopoly compared to a competitive market.
The equilibrium price would decrease, but the impact on the amount sold in the market would be ambiguous.
