K-Bank (KRX: 279570) completed its third IPO attempt on the Korea Stock Exchange in March 2026, pricing at KRW 8,300 — the bottom of its KRW 8,300-9,500 band. Despite 199x institutional oversubscription and nearly KRW 10 trillion in retail deposits, the stock fell 25.9% to KRW 6,150 by March 23, 2026.
Why the Drop?
Three structural issues are driving the selloff.
First, private equity investors (Bain Capital, MBK Partners, MG Saemaul Geumgo, NH Investment) collectively hold around 32.6% of outstanding shares and are waiting to exit. This overhang suppresses recovery.
Second, South Korea's Virtual Asset User Protection Act (July 2024) forced K-Bank to raise interest paid on Upbit crypto exchange deposits from 0.1% to 2.1%. This single regulatory change collapsed net interest margin from 1.91% (Q4 2024) to 1.41% (Q1 2025). Net income fell from KRW 128.1B (2024 record) to KRW 112.6B in 2025 (-12.1% YoY).
Third, K-Bank's deposit base grew 49.8% YoY in 2024 largely from Upbit user funds, making it uniquely sensitive to crypto market cycles.
K-Bank vs. Kakao Bank
Kakao Bank (KRX: 035720) reported record net income of KRW 480.3B in 2025, with market cap at KRW 11.8T vs K-Bank's KRW 2.5T. K-Bank's PBR of 1.38x at IPO price was below Kakao Bank's current 1.99x.
Investor Takeaway
Samsung Securities initiated with a buy rating on April 17, 2026, calling the selloff excessive. Loan growth remains at +17.6% YoY and customers grew to 13.63 million (Q1 2025). However, the FI overhang and NIM recovery timeline remain unconfirmed. Staged entry or waiting for a NIM rebound signal in quarterly results appears more prudent than immediate full allocation.
