Yes, you can increase your credit limit by creating new fixed deposits (FD).
Click on the “Credit Card” tile (top of the screen - this will take you to the credit card screen).
Click on "Increase Limit" and create a new FD. FD payment gets debited from the SBM savings account.
Example: Current credit limit is Rs. 30,000 and you create a new FD of Rs. 20,000. The new credit limit will be Rs. 50,000.
Note: The maximum credit limit can be Rs. 25 Lakhs (even if your FD is for a higher amount).
