The formula to calculate the Implied Six Month Rate (r6m) is:
r6m=(1+r1y1+r6m)2−1
Where:
Let's say the annual rate for 1 year (r1y) is 0.05 (5%) and the annual rate for 6 months (r6m) is 0.02 (2%). Using the formula:
r6m=(1+0.051+0.02)2−1≈0.0598
So, the Implied Six Month Rate (r6m) is approximately 0.0598 (5.98%).
