Symptoms

In Oracle Financial Services Asset Liability Management (ALM) 5.6 or 6.0, when you define the Forecast Rates for a yield curve using the Forecast Method "Yield Curve Twist", the rate shock is not included in the "Short Point" term point or in term points in between the Short Point and Anchor Point.  The Forecasted Rate is incorrect for this tenor. 

For example, you define the Yield Curve Twist as follows:

Anchor Point: 3 Months, Shock Amount: 0.000000
Short Point: 1 Day, Shock Amount: 0.050000
Long Point: 1 Year, Shock Amount: -0.050000

However, when you view the Forecast Rates for this method, the following is shown:

BucketStart DateEnd Date1 Days1 Months3 Months6 Months1 Year
Base     5.100000 5.200000 5.397000 5.543000 5.669000
1 9/1/2012 9/30/2012 5.397000 5.397000 5.397000 5.471000 5.619000

The Short Point of 1 Day does not have a 0.05 shock up.  Instead, it has the same rate as the Anchor Point 3 Month term point.  The "Long Point" rate is correct.

Steps to Reproduce:

  1. Go to Asset Liability Management
  2. Go to Assumption Specification > Forecast Rates
  3. Create a Forecast Rate
  4. Define an IRC with Forecast Method = Yield Curve Twist
  5. View the Forecasted Rates

The Short Point rate is wrong.
