BNK Busan Bank launched the “Only One” preferential time deposit product on October 19, 2026, offering a base rate of 2.90% and a maximum yield of up to 4.20% annually for individual customers depositing between 10 million KRW and 100 million KRW over a 12-month term.
The Bottom Line
- Maximum Yield: Accounts can scale up to an annualized 4.20% return by stacking a 2.90% base rate with up to 1.30% in tiered preferential bonuses.
- Target Demographics: Custom qualification tracks cater specifically to salary earners, sole proprietors, and designated corporate partnership employees.
- Accessibility: The 12-month vehicle requires a minimum ticket of 10 million KRW up to a hard cap of 100 million KRW per individual via branches or mobile banking.
Structuring Deposit Yields Around Transaction Habits
The newly unveiled “Only One” time deposit attempts to capture primary banking relationships by abandoning flat-rate structures in favor of segmented qualification criteria. According to details released by the institution on October 19, 2026, depositors secure the baseline 2.90% return upon opening the 12-month vehicle. Reaching the ceiling of 4.20% requires accumulating specific operational milestones tailored to how a customer generates income.
Salary earners unlock added yield by routing monthly payroll disbursements directly through the bank or by funding personal retirement pension accounts. For sole proprietors, the qualification mechanics shift toward registering merchant point-of-sale settlement accounts and opening new subscriptions under the Yellow Umbrella Mutual Aid program.
