South Korean banks are intensifying competition for customer funds as market volatility pushes savers toward lower-risk products, rolling out installment savings accounts with advertised maximum annual returns of 7% to 10% and nudging time deposit rates higher. Shinhan Bank said it will begin selling "Shinhan Savings 9dan" on the 14th, a one-year product with a 3% base rate and up to 9% a year for customers who are new to Shinhan deposits, savings or housing subscription products and who meet Shinhan Card usage conditions. The account allows monthly deposits of up to 300,000 won, will be offered through the 30th of next month, and is capped at 200,000 accounts. Rival offers include Toss Bank's 10% "Grow It 31-Day Savings," Woori Bank's 8.29% "Our Wish Savings" and NH NongHyup Bank's 8.15% "Nongsim Cheonsim" savings account, while deposit products from NH NongHyup, Woori and Shinhan offer up to 3.7%. The highest advertised rates generally require strict preferential conditions and, in the case of installment savings, monthly caps that make them better suited to regular small-scale saving than to parking a lump sum.
