Final answer:
The consequence of reducing the bonus points on the Chase Sapphire Reserve Card will be a decreased incentive for new customers.
Step-by-step explanation:
The consequence of reducing the bonus points of signing up for the Chase Sapphire Reserve Card from 100,000 to 50,000 will be a decreased incentive for new customers. The reduced bonus points may make the card less appealing to potential customers who were enticed by the higher reward. However, it is important to note that the other options mentioned in the question are consequences of this reduction. Decreased market share, lower customer acquisition cost, and reduced brand loyalty are all potential outcomes of a reduction in bonus points.
