NatWest claims to have fixed the IT problems that locked customers out of its online, app and telephone banking services today.
The outage, though, came just a day after Barclays suffered a similar outage. That prevented customers and staff from accessing Barclays' IT systems, meaning that customers had to be turned away in-branch.
"We're aware of some issues on our Online and Mobile Banking services and are working hard to fix them. Telephone Banking and ATMs are available. Sorry and thanks for your patience," the bank tweeted this morning.

Furthermore, customers of Ulster Bank, as well as Royal Bank of Scotland, were also affected by the outage. In a statement to customers, RBS said: "We are aware that customers are currently experiencing issues logging into their online and mobile banking accounts.
"We are aware of the problem and are working to fix the issue. Customers can still use ATMs and telephone banking."
The outages, one following hot on the heals from the other, has provided a renewed focus on the shortcomings of big UK banks' IT systems.
According to Lev Lesokhin, senior vice president of strategy & analytics at CAST, UK banks are particularly prone to such repeated IT failures.
"Banks in other geographies don't have as many problems as UK banks. Based on our research, UK banks don't do as good a job controlling the structural quality of their legacy systems. So the UK banking sector has some catching up to do in getting that kind of software intelligence," he said.
As a result of its outage yesterday, Barclays is expected to be called before the House of Commons Treasury Select Committee to explain the prolonged outage.
The Treasure Committee has taken a stronger interest in UK banks' IT failures this year, following the botched migration by TSB from the Lloyd's Bank banking platform to that of its new parent, Spain's Banco Sabadell.
