The video tutorial explains interest rates as the cost of borrowing or the return on savings. In the UK, the Bank of England sets the base rate to control inflation. High inflation leads to increased rates to curb spending, while low inflation results in decreased rates to boost the economy. Commercial banks use the base rate to set their loan and savings rates, affecting consumers and businesses differently. Examples illustrate borrowing costs and savings returns. A simplistic banking model shows how banks profit from interest rate differences. The video concludes with the impacts of interest rate changes on the economy.
