What does the index represent in adjustable-rate mortgage pricing?

• A. The fixed rate used for the life of the loan
• B. The benchmark rate that changes with market conditions
• C. The margin added to determine the final rate
• D. The initial rate set at origination

Answer: (B)

In adjustable-rate mortgage pricing, the key idea is that the loan’s rate moves over time based on two components: a benchmark index and a fixed margin. The index represents the benchmark rate that changes with market conditions. It’s a published rate that can rise or fall, and it’s not locked in for the life of the loan. The lender adds a fixed margin to that index to determine the current note rate, so the actual rate you pay at any time equals index plus margin. Because the index moves, the note rate can adjust at set intervals after the initial period. For example, if the index is 2.25% and the margin is 2.75%, the current note rate would be 5.00%. The initial rate at origination may be different and is often a temporary starting rate, but it isn’t the ongoing benchmark that drives adjustments.
