financial group's net profit is biggest ever...interest business is booming.

Major domestic financial groups have posted all-time net profits of up to KRW 4 trillion in the third quarter of this year, the report showed.

According to the financial sector, KB Financial Group's net profit by the third quarter was the highest ever at KRW 4.39 trillion.

Net profit of KRW 1.614 trillion in the third quarter also increased to 17.9% from the third quarter of last year, the largest since its foundation.

Shinhan Financial Group's net profit through the third quarter was KRW 3.9856 trillion, up 4.4% from the same period last year.

Woori Financial Group's cumulative net profit rose 9.1% to KRW 2.6591 trillion in the third quarter.

The increase in net income of major financial groups is due to the increase in household and corporate loans themselves and the increase in interest profits.

Through the third quarter, KB Financial Group's interest income rose 1.3 percent from a year ago, Shinhan Financial Group's 3.3 percent and Woori Financial Group's 1.5 percent, respectively.

It is analyzed that the reduction in the loan-to-deposit margin also helped defend profitability as banks raised the additional interest rate attached to the basic interest rate to reduce household loans.
