Answer:
$25 million
Step-by-step explanation:
The interest paid on the $1 Billion loan would remain 7% as it is fixed rate loan. So the interest expense would be $70 million ($1000m * 7%).
The interest income on the saving deposits would be at floating rate which has been increased from 3% to 5%. So the interest income would be $45 million ($900 * 5%).
Net Interest Income = Interest Income - Interest Expense
Net Interest Income = $70 million - $45 million = $25 million
