The main reasons for blocking an account by a broker: customer violation of broker rules and regulations, unfair or manipulative trading, financial difficulties of the trader, court decision or other government body, security breaches.
Blocking an account by a broker is an unpleasant situation. You try to log into your account again, but it is blocked. Most often this occurs due to unauthorized entry attempts or due to trader violations of the Agreement and trading conditions. But there are other reasons, which you will learn about from this review.
Why a broker can block a trader's account?
Brokerage accounts are the property of traders, but they are also the property of brokers. This means that brokers have the right to block the accounts of their clients in certain cases.
Main reasons for blocking a brokerage account:
Customer violation of broker rules and regulations. The broker's contract with the client usually specifies the rules and regulations that the client is required to follow. If the client violates these rules, the broker may block their account.
For example, a broker may block a customer's account for the following violations:
Customer violation of broker rules and regulations. The broker's contract with the client usually specifies the rules and regulations that the client is required to follow. If the client violates these rules, the broker may block their account.
Failure to provide or provide inaccurate information about the customer.
Using a brokerage account to conduct illegal transactions.
Failure to comply with established limits on the conduct of transactions.
Failure to comply with the deadlines for payment of commissions and other payments.
Brokers necessitate identity verification to combat money laundering and fraud. If a trader fails to provide the required identification documents or the provided information raises concerns, the broker may temporarily block the account until the verification process is completed.
2. Unfair or manipulative trading. Brokers are obliged to ensure fair pricing on the market. If a broker suspects that a trader is engaged in unfair or manipulative activities, they may block their account.
For example, a broker may block a trader's account for the following actions:
Pumping stocks or bonds.
Artificially lowering or raising asset prices.
Using insider information.
Each broker establishes terms and conditions governing the use of its platform. Violating these terms, such as engaging in prohibited trading strategies or exploiting system vulnerabilities, can lead to account suspension.
3. Financial difficulties of the trader. If a trader is unable to repay their debts to the broker, the broker may block their account.
For example, a broker may block a trader's account for the following debts:
Commissions and other payments.
Debt on margin loans.
Debt on loans issued by the broker.
Court decision or other government body. In the event of legal or administrative proceedings against a trader, the broker may block their account by court order or another government body.
For example, a broker may block a trader's account by court order to collect a debt, by an arbitration court order to suspend the trader's activities, or by a law enforcement agency order to conduct an investigation.
5. Security Breaches. Instances of unauthorized access, hacking, or other security breaches may lead to immediate account suspension. Brokers prioritize the safety of their clients' funds and personal information, and any compromise prompts swift action.
Trader rights upon blocking a brokerage account

The trader also has the right to appeal the decision to block the account. To do this, they must file a complaint with the brokerage company. The brokerage company is required to consider the complaint within 30 days of receiving it.
If the decision to block the account is upheld, the trader may appeal to court.
