I am guessing this is related to cryptocurrency trading using an account/card with them.Dear Customer,
Greetings from ICICI Bank.
We would like to bring to your notice the below important information on permissible usage of card transactions involving foreign exchange:
• Under the Foreign Exchange Management Act (FEMA), 1999, a resident Indian is permitted to make only those foreign exchange transactions on ICICI Bank Cards or Account that are permissible and remittance in any form towards overseas exchange trading through internet/ electronic trading portals is not permitted.
• Indian residents are therefore prohibited from trading in foreign exchange in domestic and overseas market, including binary option trading with commodities, stocks, indices, bitcoin index and forex etc.
Please make note of the prohibitions on using your ICICI Bank Cards or Account for such unauthorised transactions in contravention to the FEMA and the regulations issued thereunder and that violation(s), if any, would attract action under the extant laws and regulations against such residents.
In case such transactions are noted on your ICICI Bank Cards or Account, we shall be constrained to close your card or account without any liability or responsibility on the part of the bank.
Looking forward to your co-operation in helping us serve you better.
ICICI Bank Limited
