Specialized banks, including such state policy lenders as the Korea Development Bank  and the Export-Import Bank of Korea, suffered a net loss of 3.5 trillion won last year, far more than 600 billion won posted a year earlier.

Their loan loss expenses rose by 2.2 trillion won to 8.9 trillion won amid the restructuring of Daewoo Shipbuilding & Marine Engineering and STX Offshore & Shipbuilding Co.

The KDB posted 3 trillion won in net losses in 2016, the largest deficit since 1998 when the country was reeling from a foreign exchange crisis.

In contrast, the net profit of commercial banks headquartered in Seoul jumped 32.5 percent on-year to 5.5 trillion won in 2016.

Meanwhile, the return on assets of South Korea's banks dipped to 0.13 percent, down 0.08 percentage point, with the return on equity also sliding 0.93 percentage point to 1.65 percent.

Both the ROA and ROE recorded the lowest level since 2000.
 
Their interest income rose 2.7 percent to 34.4 trillion won.

"This was because the value of assets under management rose 5.8 percent, while the net interest margin was reduced," the FSS said. "The NIM sank to an all-time low of 1.55 percent due to a continued fall in loan-deposit margin."

Their non-interest income decreased 1.1 trillion won to 4.9 trillion won in the year due to declines in service fees and commissions as well as securities income.

Commercial banks’ ROA and ROE added 0.08 percentage point and
0.99 percentage point to 0.45 percent and 5.88 percent, respectively. (Yonhap)
