Question

If interest rates rise, how do you adjust your AI-driven &#x27;what-if&#x27; model to correctly calculate the change in a bank&#x27;s Net Interest Margin?

Accepted Answer

Net Interest Margin is the profit a bank makes from the difference between the interest it earns on loans and the interest it pays to people who keep money in savings accounts. To adjust your AI model for rising interest rates, you must first update the rates for your assets, which are the loans the bank has given out. You calculate how many of these loans have variable rates that move up automatically when market rates rise. Next, you update the rates for your liabilities, which are the savings accounts where the bank owes interest to customers. You need to adjust your model to show that these costs will likely go up too, but often at a slower speed than loan income because banks do not always raise savings rates immediately. Think of this like a water tank where the inflow pipe for loans opens faster than the outflow pipe for savings costs. Finally, you must add a step to estimate customer behavior, as some people might move their money elsewhere if the bank keeps savings rates too low for too long. By plugging these three things—loan income, savings costs, and customer choices—into your model, you can see how the gap between what the bank earns and what it pays changes when rates shift.
