Our verdict

K Bank pays 4.2% fixed on a fixed-term deposit running 6 to 36 from a minimum deposit of KRW 1,000, so it suits Korean savers who can leave money untouched. Interest is paid in a lump sum at maturity, and support runs on chat, help centre and phone.

Pros and cons

Pros

  • A fixed rate of 4.2% across a term of 6 to 36, so the return is set before you start saving.
  • The minimum deposit is KRW 1,000, which makes this an approachable first term deposit.
  • Deposits go in monthly under the access terms, and a limited number of partial withdrawals are allowed along the way.
  • Support runs on chat, help centre and phone, so help is by phone, chat or the help centre.

Cons

  • The access terms pay interest in a lump sum at maturity and allow only a limited number of partial withdrawals, so nothing accrues in your pocket along the way.
  • The 6 to 36 term locks the balance, and a fixed rate cannot be repriced if market rates move higher.
  • Support is limited to the channels listed under chat, help centre and phone, with no email option in that set.

Who it suits

  • Savers in Korea with a lump to place for a fixed stretch and a preference for a known return.
  • First-time savers, since the minimum deposit is KRW 1,000 and the account runs 6 to 36.
  • Borrowers as well as savers: personal loans run at 5.58% to 10.16% on amounts up to KRW 300,000,000, against a hard credit check.

Who should look elsewhere

  • Anyone who needs instant access: bunq at 3.01% and Wise at 3.29% suit savers who would rather not tie money to a 6 to 36 term.
  • Savers after a shorter commitment: Finteres carries a headline rate of 0% to 36% and covers the brief deposit windows of the listed brands.

Frequently asked questions

What rate does K Bank pay, and for how long?+

K Bank pays a fixed rate of 4.2% on a fixed account running 6 to 36. The account kind is fixed, so the money is committed for the stretch rather than held on call. That suits anyone who can leave a balance where it is.

How much do I need to open the account?+

The minimum deposit is KRW 1,000, and the access terms set a monthly deposit range with contributions going in each month. Interest is paid in a lump sum at maturity, and a limited number of partial withdrawals are allowed during the term, so a small opener works for a first deposit.

Can I get my money out early?+

The access terms allow a limited number of partial withdrawals, while interest is paid in a lump sum at maturity rather than along the way. Early access is therefore partial by design, so plan for the balance to stay put for the full 6 to 36.

Is the deposit protected?+

The listed regulator is the Korea Deposit Insurance Corporation in South Korea. The account itself is a fixed deposit held in Korean won from a minimum of KRW 1,000. Read the scheme's own terms for what the cover applies to.

How do I get help from K Bank?+

Support runs on chat, help centre and phone, so you can reach the bank by phone, through chat or via the help centre. That listing also covers the opening hours for each channel, so check it before you call.

What does the card cost to hold?+

The rewards card has an annual fee of KRW 0 and the currency conversion fee is 1.35%. Purchases earn 1% K Bank Point on all purchases, and Up to 10% discount at GS25 convenience stores adds a store discount. It is a debit card aimed at everyday spend.

Who can borrow from K Bank?+

The personal loan runs at an APR of 5.58% to 10.16% on amounts up to KRW 300,000,000, with a hard credit check and good credit needed. Free early repayment is available and there is no origination fee, though stamp duty applies and is shared with the bank.

How does the rate compare with other brands?+

K Bank's 4.2% is fixed and sits above the site median of 3%. The comparison brands here list 3.01% for bunq and 3.29% for Wise, so K Bank leads on the headline number, at the cost of a term commitment.
