South Korea's five major commercial banks are raising deposit rates while expanding inheritance-related trust and advisory services. Woori Bank raised the top one-year rate on its Woori First-Time Customer Preferred Fixed Deposit from 3.1% to 3.6% annually, the highest among major commercial-bank fixed deposits, while Shinhan, Hana and NH NongHyup also increased rates and KB Kookmin is reportedly reviewing a rise. Kookmin, Shinhan, Hana, Woori and NongHyup have launched or are preparing more than 10 inheritance-related products this year, including dementia-care trusts, senior-residence deposit transfers and milestone-based gifts from grandparents to grandchildren. Law firms are adding inheritance, gift, tax, family-business succession and dispute-prevention services as family estate conflicts increase. Mutual finance institutions are also raising deposit rates, with average one-year rates around 3.6%-3.7% and some regional products above 4.2% or 4.3%. Savings banks are moving in the opposite direction: their average one-year rate fell to 3.73%, while products offering at least 4% declined from 105 at the end of July to 13. The divergence reflects savings banks' reduced need for deposits after securing liquidity for second-half maturities and difficulty expanding loans amid tighter household-credit management. Household loans at the five major banks fell by ₩1.1514 trillion as of the 10th, the first monthly decline in six months. Rising funding costs, including a five-year bank-bond rate of 4.578% and July new-loan COFIX of 3.18%, could put further upward pressure on variable-rate lending.
