Interest Rate Risk
Interest rate risk is the risk that changes in interest rates will affect the company's cash flow, financing cost, investment income, or balance sheet value.
For treasury, the practical question is simple: if rates move, what does that do to the company's money?
Where the risk usually comes from
Interest rate risk often arises from:
- floating-rate debt
- short-term borrowing
- cash deposits and investments
- refinancing needs
- mismatches between assets and liabilities
The risk can work both ways. Rising rates may increase borrowing cost but improve deposit income. Falling rates may do the opposite.
Why treasury pays close attention
Interest rate movements can change funding cost quickly, especially for companies with variable-rate debt or frequent refinancing needs. Treasury therefore monitors the exposure so management is not surprised by higher cash interest expense or weaker returns on surplus cash.
How companies typically respond
Responses vary by risk appetite, but treasury may:
- fix part of the debt profile
- keep a mix of fixed and floating exposure
- use derivatives such as interest rate swaps
- set policy limits on acceptable exposure
- review scenarios under different rate environments
Why this is not only a debt topic
People often associate interest rate risk only with borrowing, but it also matters for deposits, investment strategy, and broader balance sheet structure. That is why treasury usually looks at both sides rather than treating debt in isolation.
Where governance matters
Because the topic involves market risk and judgment, companies normally define limits, authorities, and hedging principles in treasury policy. A useful policy does not try to predict rates. It defines what treasury is allowed to do when rates move.
