Interest Rate Risk

Cash flows generated by ERM are discounted in accordance with the term structure of interest rates. ERM simulates individual interest rates for a specified set of maturities and captures both parallel and non-parallel shifts in the yield curve. Interest rate risk is incurred when there is a mismatch between the company’s assets and liabilities. The mismatched income is subject to the interest rate risk of the specific time bucket in which it occurs. Cash flows are assigned to time buckets (vertices) in accordance with the RiskMetrics methodology that is covered in the next section.

Yield curves follow complicated paths and non-parallel shifts. Therefore, duration is not adequate as a measure to capture this risk.
