Well it is an important factor.

Average bond yield is around 4% over a decade, that means that investing in a business you need to discount the growth it will have in it's cash flow by 4%.

Imagine you conclude Coca Cola can grow it's cash flow and earnings per share by 6% annually, is it an appealing investment when you get right now almost 5 on bonds? I's not really, but you would probably come to a different conclusion if Coca Cola's price felt by 15% in some market conditions.
