Their loan portfolios grew 11% to $154.3 billion, led by new car loans ($18.5 billion, +17%), used cars ($17.8 billion, +12%), and credit cards ($18.4 billion, +14%).

The largest percentage gain in the portfolios was made by private student loans, which rose 59% to $438.7 million. But those loans accounted for less than 1% of total loans even among the six that engaged in student lending.

The student lenders were Navy Federal of Vienna, Va. ($82 billion in assets, 7,188,926 members), Pentagon Federal Credit Union of Alexandria, Va. ($22.8 billion in assets, 1,604,361 members), BECU of Seattle ($17.2 billion in assets, 1,044,378 members), Alliant, First Technology Federal Credit Union of Mountain View, Calif.

Credit union executives have said that they expect the cooling of the refinance boom to dampen overall mortgage originations.

That real estate slowdown can be seen in the value of loans granted during the three months ending June 30. The top 10 granted $8.9 billion in real estate loans during the second quarter, up 1%, while grants of non-real estate loans rose 13% to $16.6 billion.

While total real estate originations rose 36% at Alliant and 16% at PenFed, they fell 45% at Star One, 26% at Golden 1, 21% at Security Service of San Antonio, Texas and 9% at First Technology of Mountain View, Calif.,. The others recorded single-digit gains.

The biggest increase in profits was at State Employees' Credit Union in Raleigh, N.C.: They more than doubled from the $37.9 million earned in 2016's second quarter to $80.9 million in the three months that ended June 30. The biggest factor was the timing of one-time gains between the first and second quarters.

Profits nearly doubled to $12.6 million at Security Service ($9.6 billion in assets, 746,605 members). Non-interest income rose 14% while non-interest expenses were flat.

First Tech was the only credit union in the group to show a decline in net income. It fell 27% to $23 million. Non-interest income was flat while non-interest expenses rose 24%.
