Preliminary combined net income for the 12 Federal Home Loan Banks jumped 25.9 percent to $730 million in the second quarter of 2013, up from $580 million in the first quarter, according to the Federal Home Loan Bank Office of Finance. The FHLBanks’ net income for the six months ended June 30, 2013, was $1.310 billion, a 1.9 percent increase compared to the same period in 2012. “These increases were driven primarily by improvements in non-interest income and reductions in non-interest expense, partially offset by lower net-interest income,” noted the Office of Finance.
