Which of these would increase a company's WACC?
- A A fall in the risk-free rate
- B An increase in the company's business risk and beta
- C Repaying expensive debt with cheaper debt

Answer
An increase in the company's business risk and beta
Higher beta raises the cost of equity through CAPM, which raises WACC. The other options all reduce the cost of one component of capital.
