South Korea’s top four financial groups—KB, Shinhan, Hana, and Woori—are projected to have achieved a combined annual net profit exceeding 18 trillion won in 2025, marking yet another historic high. Despite the challenges of a rate-cutting cycle and tightening household debt regulations, a significant surge in non-interest income, particularly from Wealth Management (WM), bolstered the bottom line.

Breaking the "6 Trillion" and "5 Trillion" Milestones
According to market data provider FnGuide on January 9, the estimated total net profit for the four groups in 2025 stands at 18.35 trillion won. This represents a 12.24% increase from the previous year’s 16.35 trillion won.

KB Financial Group: Expected to reach 5.82 trillion won, nearing the unprecedented "6 trillion won club" just one year after becoming the first Korean firm to surpass 5 trillion won.
Shinhan Financial Group: Forecasted to join the "5 trillion won club" for the first time with 5.15 trillion won, marking the highest growth rate among its peers at 15.8%.
Hana & Woori: Hana is expected to record 4.08 trillion won, while Woori is projected to hit 3.30 trillion won, both setting new internal records.

Fee Income Offsets Declining Interest Margins
The record-breaking performance was driven by the expansion of non-interest income from WM and Investment Banking (IB) sectors. While Net Interest Margins (NIM) faced downward pressure due to lower interest rates, the decline was less severe than anticipated.

Total interest income for the four groups fell by only 4.12% compared to 2024. This gap was effectively filled by a booming stock market, which boosted the performance of securities subsidiaries and increased commission fees from bancassurance and trust products.

 
Potential Headwinds: ELS Fines and Regulatory Changes
Despite the stellar results, several "variables" loom over the financial sector:

Hong Kong ELS Fines: Authorities have signaled heavy fines regarding the misselling of Hong Kong H-Index Equity-Linked Securities (ELS). KB Kookmin Bank faces an estimated 1 trillion won fine, while Shinhan and Hana may face around 300 trillion won each. As these are recognized as accounting expenses rather than provisions, they will directly impact net profits in late 2025 or early 2026.
Increased Taxation and Regulation: Starting this year, the education tax rate for financial firms with profits exceeding 1 trillion won will double from 0.5% to 1%. Furthermore, new amendments to the Banking Act will prevent banks from reflecting certain legal costs in loan spread rates, potentially adding a 3 trillion won cost burden to the industry.

2026 Outlook: Slowing Growth
Analysts predict that the aggressive growth seen in 2025 will likely slow down. FnGuide estimates 2026 net profits to grow by a modest 2–3% to approximately 18.87 trillion won.

"Bank loan growth is expected to slow from 4.4% last year to 3.8% this year due to strict government management of household debt," said Jun-seop Jeong, a researcher at NH Investment & Securities. "While NIM may continue to drop through the first half of the year, we expect non-interest income to remain a key buffer as investment demand in the capital markets continues to grow."
