The mortgage refinance boom helped propel Wells Fargo & Co. profits up 24 percent in the fourth quarter, capping a strong year for the nation's top mortgage lender.
The San Francisco-based lender kicked off the bank earnings season Friday, reporting fourth-quarter profits of $5.1 billion, or 91 cents per share, on sales of $21.9 billion, up 7 percent from a year ago. The results beat consensus Wall Street expectations on both profits and sales.
For the year, the bank's profits were $18.9 billion, or $3.36 per share, up 19 percent from 2011 and beating the consensus analyst expectation by a penny a share.
Mortgage banking income remains a key driver of the bank's profit growth, but Wells Fargo also saw gains from loan growth, increased trust and investment fees, improved credit quality and a reduced need for reserves to cover soured loans.
The bank, which employs about 20,000 people in Minnesota, also reaped above-average private equity gains. That was largely related to Norwest Equity Partners' $1 billion sale of Iowa seed treatment company Becker Underwood Inc.
Still, the bank made fewer new home loans in the fourth quarter than in the third, and its net interest margin -- a key bank measure that shows the difference between what a bank makes on loans and what it pays in interest -- shrank more than analysts expected, to 3.56 percent. The bank blamed the margin shrinkage on strong deposit growth of $30 billion.
Banks of all sizes have seen their net interest margins squeezed by ultra-low interest rates and sluggish loan demand, with customers generally more interested in stashing deposits than taking on debt, an ongoing problem in the industry.
Investors sent Wells Fargo shares down Friday about 1.5 percent as bank stocks in general retreated.
