In banking and personal finance, a Zero Balance account is one that requires no minimum balance to be maintained. These accounts—often offered to salaried employees or Jan Dhan account holders—provide access to basic banking services without the risk of penalty charges for low balances. In the context of trading and investments, a zero balance in a demat or trading account means no holdings or uninvested funds are present. Investors should be mindful that maintaining a trading account with a zero balance over a long dormancy period may result in the account being flagged as inactive under SEBI and exchange guidelines.
