Higher interest rates helped Wells Fargo & Co. land more than $3 billion in profit in the third quarter. From a capital perspective, they also wiped out nearly three-quarters of that.

At Wells Fargo, it was an additional $2.4 billion in unrealized losses on mortgage-backed securities and other bonds that weighed on shareholder equity in the third quarter.
