Yes, you can.
You can buy a safe locker from the bank and store your gold there. (There is no interest involved.) However, you will have to pay annual locker rental charges. Alternatively, some banks require you to open a fixed deposit, typically around Rs. 50,000 or more. This depends on the bank and its locker policy.
Currently, most banks have limited availability of lockers, so you may have to join a waiting list until a locker becomes available.
Banks offer different types and sizes of lockers, depending on the branch. Most banks have at least two size options, and charges vary based on the locker size and storage capacity.
Another option is to pawn your gold at the bank and place a fixed deposit (FD). In this case, you’ll need to pay the gold pawning interest, but you will also earn interest on the FD, which may help offset the cost.
