The fund you bought through this bank should not be affected, but now you should take the initiative to contact the fund company to find out which bank is the custodian of the fund. There are two concepts to be clarified:

First, which bank did the fund company that you bought the fund products entrust the assets of this fund to? If it is Busan Bank, ask the Foundation whether it will change the custodian bank. Because, after all, banks are closed for rectification, there is some uncertainty in fund assets. However, as an investor, the role it can play in this issue is very limited, mainly depending on the attitude of the fund manager (that is, the fund company) towards this custodian bank. If it is not Busan Bank, but other well-known big banks in South Korea, then don't worry.

Second, you bought the fund through Busan Bank, which is the sales organization of the fund. This involves that you want to redeem the fund, but how can you get your money because Busan Bank went bankrupt? The best way is to contact the fund company and tell them that you want to transfer custody, that is, transfer the consignment agency of your account to other big banks. Because Busan Bank is closed now, I wonder if it can be transferred to custody? Or you can ask for redemption now and see what solutions they can offer.

Good luck!
