Explain how interest-rate changes affect businesses
Trace interest rates through business borrowing, customer spending and the response a firm could consider.
Section 6 · External influences on business activity
Cambridge IGCSE (9–1) Business 0774, 2027–2029 Version 2, Topic 6. Trace each external change through the business and state which effects depend on its market, costs or response. Candidates are not assessed on exchange-rate calculations. Written practice is self-checked and does not certify exam readiness
Before you begin
- No previous study of external influences is assumed. Identify who is affected, which business decision changes and what evidence or condition would affect the outcome.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What is a possible direct effect of higher rates on a variable-rate business loan?
What you will learn
- Explain borrowing-cost effects
- Explain possible customer-demand effects
- Recommend a response using debt and demand evidence
Borrowing costs can change
When interest rates rise, variable-rate borrowing may become more expensive, and new borrowing may cost more. This can reduce profit or make an investment harder to afford. The effect depends on the firm's debt, rate terms and cash flow.
When rates fall, some borrowing costs may fall, but existing fixed-rate debt may not change immediately. A business should read its contract instead of assuming all interest payments move at once.
Customer demand can also respond
Higher rates can increase mortgage or loan costs for some households and may reduce discretionary spending. Lower rates may ease some payments or make borrowing more attractive, but customers' responses differ.
A firm could review borrowing, investment timing, cash forecasts or pricing. It should not cut worthwhile investment or assume more sales merely because rates changed; compare the likely cost or demand channel with actual evidence.
Pause and explain
What should a firm check before changing investment after a rate move?
Worked example
A company has a variable-rate loan and plans to borrow more for expansion. Explain how a rate rise could affect its decision.
Show the worked solution
- The existing variable-rate loan payment may rise under its terms.
- New borrowing may also have a higher cost.
- Compare forecast cash flow and expected expansion returns before deciding.
Answer The company may face higher interest payments on its variable-rate loan and more expensive new borrowing. It should test whether expected expansion cash flows can cover the changed repayments and compare delaying, reducing or proceeding with the investment using current evidence.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Interest rates rise and a manufacturer has an existing variable-rate loan. Explain the likely financial pressure and one response to assess.
Give me a hint
Link the rate term to repayment then examine available options.
Compare my reasoning
- Variable interest may increase the repayment cost.
- This can reduce profit or cash available for operations.
- Review cash forecasts, financing alternatives and investment priority.
The manufacturer's interest cost may rise, reducing profit or cash available for operations. It should review its forecast, the loan terms and alternatives; refinancing or delaying an investment should be compared for total cost and operational impact.
Look for these in your work
- Rate effect linked to contract
- Profit/cash route
- Response compared
Rates fall, but a retailer's loan has a fixed rate until next year. Explain why its current loan payment may stay unchanged while a new project could still be affected.
Give me a hint
Separate the existing fixed contract from new financing and customer channels.
Compare my reasoning
- A fixed rate normally stays set for its agreed period.
- A new loan may be offered at different terms.
- Customer spending may also respond, but the direction is not certain for every group.
The existing loan payment may remain unchanged until the fixed period ends. A new loan could have different pricing, and some customer spending may respond to lower rates; the retailer should check actual offers and demand before revising its plans.
Look for these in your work
- Fixed term understood
- New finance distinguished
- Demand response qualified
A restaurant considers cancelling staff training because higher rates increase borrowing costs. Explain what it should compare before deciding.
Give me a hint
A financing shock matters, but training may affect service and future revenue.
Compare my reasoning
- Estimate cash saved by cancelling or delaying training.
- Assess training's effect on service, errors and customer returns.
- Compare alternatives such as phasing the training or reviewing other costs.
The restaurant should compare the near-term cash saving with possible effects on service quality, errors and repeat visits. It could phase training or review other costs; cancelling may ease cash temporarily but harm the business if service deteriorates.
Look for these in your work
- Short-term saving
- Long-term operating effect
- Alternative response
Common mistakes
- Assuming every existing loan reprices immediately
- Treating rate changes as affecting only businesses and never customers
- Assuming lower interest rates guarantee profitable investment

What is a possible direct effect of higher rates on a variable-rate business loan?
Compare with the explanation
Interest payments may rise
The loan's rate terms determine the change.
