Interest rates influence nearly every part of the economy. They affect how many people pay on home, car, and business loans. They also influence investments, costs, and jobs.

Inflation
Inflation is the major factor. If inflation is too high, higher interest rates are required, while if inflation is low, lower interest rates are better.
Employment

- How many people are employed?
- Are companies hiring new staff?
- Is unemployment increasing with time?
A good job market mostly helps the economy id going better.
Economic Growth
Economic growth tells how much the country’s economy is growing. If economic growth is too slow, a lower interest rate may motivate more investments. If economic growth is fast and increasing inflation, high interest rates are better.
Business Investment
Businesses usually take loans to build industries, purchase machines, and hire new workers. If the companies are investing little, the central bank may decrease interest rates to motivate more investment.
Worldwide Economy
Countries trade with each other everyday. Issues in one country can influence the other ones. Central banks also review international trade, exchange rates, political changes, and oil prices. These factors can affect inflation and economic growth also.

Conclusion

They make these decisions by carefully studying inflation, employment, economic growth, consumer spending, business investment, and conditions around the world.
