Korea's Top 5 Banks See Fixed Deposits Surpass 1,012 Trillion KRW as Rates Rise

The Quick Take

• South Korea's five major banks — KB, Shinhan, Hana, Woori, and NH — collectively hold over 1,012 trillion KRW in term deposits
• Term deposits grew by nearly 75 trillion KRW since May 2026 as banks raised key savings rates to attract inflows
• Rapid deposit growth signals a rotation of liquid funds into higher-yielding fixed products, reflecting cautious household risk appetite

South Korea's five largest commercial banks have accumulated combined term deposit balances exceeding 1,012 trillion KRW, driven by a 75 trillion KRW surge since May 2026 as these institutions sequentially raised benchmark savings product rates to attract retail deposits. The rapid inflow into fixed deposits reflects a household sector rotating away from equities, mutual funds, and other variable-return instruments toward capital-protected yield products, consistent with a risk-off posture amid global macro uncertainty and domestic property market softness.

Rising deposit balances strengthen bank net interest margins only if matched by strong loan demand at higher rates. Korean banks are in a transitional period where deposit costs are rising while household credit growth remains constrained by macroprudential lending limits — a margin squeeze risk that could pressure profitability at KB, Shinhan, Hana, Woori, and NH in their next quarterly results. The deposit surge also signals that Korean household savings rates are rising at the expense of discretionary spending, consistent with a broader consumer caution theme across Northeast Asia.

Watch Korean financial holding company Q3 earnings for net interest margin guidance — the spread between rising deposit costs and asset yields will determine whether the deposit surge is accretive or dilutive to bank profitability. The macro variable is the Bank of Korea rate decision: if the BOK cuts rates, deposit rates would normalise and some of the 75 trillion KRW surge could reverse into equities and real estate, providing a consumption and asset market catalyst. Monitor Korean equity fund inflows as a leading indicator of any deposit-to-equity rotation that a rate cut would trigger.
