Partial withdrawal from the standard time deposit account is allowed before the end of maturity for all maturities. In this case, interest accrued on the withdrawn portion shall be canceled. However, the same value date, maturity, and interest rate are valid for the balance thereof. The balance of your standard time deposit account should at least be equal to the lower limit for account opening. If the balance falls below the said limit, then you shall have to withdraw all the funds in your account.
