CMA warns Monzo over transaction history breaches

The Competition and Markets Authority (CMA) has issued a warning to Monzo after it breached a rule requiring it to send banking transaction histories to over 143,000 former account holders.

The Retail Banking Market Investigation Order 2017 means banks and building societies are required to send customers a history of their current account banking activity, called a “transaction history”, within 40 days of a customer or small business closing their current account.

Transaction histories must be sent to at least 95 per cent of such customers within 10 working days.

The CMA said it introduced this measure to make switching banks easier and to address concerns that customers who switched would lose access to their banking history, which is a key requirement for accessing credit.

Bank of Ireland, NatWest Group, and Virgin Money also breached the regulation in a similar way according to competition watchdog.

In total, nearly 150,000 customers were not provided with their transaction history in the necessary timescale.

Some transaction histories were provided a few weeks late, while others have been delayed by more than a year.

The CMA said it has written to each of the 4 banks, which are sending all outstanding information to the affected customers.

If the banks breach the order again, the CMA can take further action by issuing legally binding ‘Directions’.

These could include banks having to introduce specific training or carrying out annual compliance audits to prevent this from happening in the future.

“Nearly 150,000 people were affected by these banks’ breaches, with the majority being former Monzo customers,” said Adam Land, CMA senior director of remedies business and financial analysis at the CMA. “This may have made things harder for people trying to borrow money or apply for a mortgage.”

“The CMA’s work in the sector is making it easier for people to get a better deal from their bank. Banks must comply with all the rules – that includes providing a full transaction history promptly. We will be watching closely to make sure these leading names stick to their word and don’t let their customers down again.”

He added: “The Bank of Ireland, Monzo, Natwest Group, and Virgin Money should be in no doubt that the CMA stands ready to take further action if these failures are repeated.”
