Why Are My Income Simulation Results so Strong in a Shock?

In performing model validations for credit unions, we often see income simulation results that show significant improvement in net interest income (NII) and net income (NI) as rates rise, even for credit unions that have material positions in long-term, fixed-rate assets.  Why does this happen, and is it reasonable? Income simulations are commonly run with […]

Is Your Interest Rate Risk Model Incorporating the Risk of Deposit Mix Changes?

Recently, we blogged about interest rate risk (IRR) modeling methodologies that can give credit unions a false sense of security. (See blog titled “Is Your Risk Methodology Giving You a False Sense of Security?” Posted on July 3, 2014.) We noted that traditional income simulation seldom incorporates the risk of non-maturity deposit withdrawals or member […]

Examiner FAQs

We frequently hear about examiner inquiries regarding non-maturity deposit assumptions in credit union A/LM models.  The question is usually along the lines of, “what are the non-maturity deposit assumptions used in the A/LM modeling and how were they determined?” Non-maturity deposit assumptions include pricing sensitivity and withdrawal sensitivity.  When it comes to pricing sensitivity the […]

Static Income Simulation – Things To Consider

One of the traditional approaches to income simulation is to use a static balance sheet, which assumes that a credit union’s mix of assets and liabilities remains constant, regardless of external forces.  In other words, static analysis assumes that every dollar of mortgages that matures is immediately put back into a new mortgage at the […]
