A major IT shutdown that stops customers from making payments happens to at least one UK bank every day, Which? Money analysis has found.
In the most comprehensive analysis carried out since banks started disclosing serious IT and security failings last year, we identified 302 incidents affecting customer transactions in the last nine months of 2018.The data reveals that major banking crashes are far more common than previously thought.
Read on to find out how many glitches and security breaches your bank suffered.
Since April last year, the Financial Conduct Authority (FCA) has required banks to inform them of any major operational or security incidents which affect payment processing.
In total, 302 reports were made between 1 April 2018 and the end of the year, Which? Money found by analysing the latest reports from 30 banks and building societies.
Barclays reported the most major incidents (41), at more than one every week in the last nine months of 2018. It was followed by Lloyds Bank (37), Halifax/Bank of Scotland (31), NatWest (26), RBS (21) and Ulster Bank (18).
TSB, where the botched introduction of a new IT system last year caused 1.9 million people to lose access to online banking services, reported 16 incidents.
You can see the full data in the table below. Note that figures relating to banks within the same group cannot be added together to form a total because a single incident may have affected multiple brands within the group.
Major IT/security failings reported to FCA (1 Apr to 31 Dec 2018)
Spokespeople for Barclays, RBS Group and Lloyds Banking Group (which includes Halifax and Bank of Scotland) emphasised how seriously their organisations take IT glitches, no matter how minor.
Unfortunately, the data does not tell us how long services were unavailable for in each instance reported to the FCA.
When online banking goes down, you may need to rely on cash, but what if it's no longer an option?Our latest findings, along with incidents like last year's Europe-wide Visa payments outage, suggest that Britain's financial system has a long way to go before it will be resilient enough to support a cashless society.
Which? Money editor Jenny Ross says: 'Our research shows that these major banking glitches, which can cause huge stress and inconvenience to those affected, are even more common than we feared.'
'This highlights why it is so important that a regulator is given responsibility to protect cash and other non-digital payments as a back-up when technology fails and to ensure no-one is left behind as cashless payments grow in popularity.'
The lack of resilience in UK banks' remote banking systems is just one the reasons we're demanding the government steps in to secure the future of cash.
These include people like Gem Turner, from Yorkshire, who need cash to do the 'everyday things that a 25-year-old wants to do'.
Gem has brittle bones and uses a powered wheelchair. She told us:'I'd lose my independence if I didn't have access to cash.'
