(IRR).

The risk associated with a change in interest rates.

This may take several forms in the treasury context.

For example, and depending on the direction of the change:

- Increasing interest cost
- Falling interest income
- Changing market value of debt, or of pension liabilities
- Differences in competitiveness
- The changing nature of a market when interest rates change
- Secondary effects, especially potentially adverse effects, resulting from any of the primary effects above. For example, potential breaches of interest cover covenants.

Sometimes written 'interest-rate risk'.

Not to be confused with Internal Rate of Return, which is also abbreviated to *IRR*.
