Fluctuation

Definition

Fluctuation refers to the variation, either upward or downward, in economic variables like prices, interest rates, and market values. In finance, fluctuation tends to describe the changes seen in the prices of stocks, bonds, or commodities in the market. Similarly, it can depict the broader “ups and downs” characteristic of economic activity.

Fluctuations can be attributed to diverse factors, including market sentiment, supply-demand imbalances, geopolitical events, and macroeconomic policies. They can range from slight and gradual changes to dramatic and abrupt shifts.

Examples

Stock Market Prices: Over a trading day, the price of a share in a company may fluctuate due to investor behavior, market news, or financial reports.
Interest Rates: Central banks may change interest rates in response to economic conditions, leading to fluctuations that affect loans, mortgages, and savings rates.
Commodity Prices: Prices of commodities such as oil, gold, and agricultural products often oscillate due to changes in supply and demand, geopolitical tensions, or environmental factors.
Currency Exchange Rates: Foreign exchange markets experience fluctuation due to a host of influences including economic reports, trade balances, and political events.
