Is it reasonable not to inform me of the bank card freeze?

The situation depends on the reason and organization of the freeze.

Generally speaking, there are several situations that may cause the bank card to be frozen:

1. Bank risk control: In order to prevent card theft, money laundering, fraud and other risks, banks will monitor the card transaction behavior, and will temporarily freeze the card use if it is abnormal to protect customers' funds. In this case, the bank will notify the customer by SMS or telephone and tell the method of thawing.

2. Judicial freezing: The court or public security organ freezes the bank cards of the persons involved in the case according to law for the purposes of executing judgments, investigating cases and recovering illicit money. In this case, the freezing institution will issue a freezing notice to the bank and notify the frozen person when necessary. However, if the notice will hinder the judicial work, or the frozen person cannot be contacted, the freezing organ may not notify.

3. Internal freezing of banks: In order to protect their own interests, banks will freeze some cards that violate bank regulations, such as arrears, overdue and breach of contract. In this case, the bank will decide whether to notify the customer according to the terms of the contract and ask the customer to fulfill the corresponding obligations.
