The bank's share price stands at 180p, valuing it at £1.58bn.
David Duffy, Chief Executive Officer, commented:
"This is truly a landmark day for CYBG as we move towards becoming an independent banking group for the first time in almost a century and we are delighted to be listing on both the London Stock Exchange and the Australian Securities Exchange.
"CYBG is in great shape to begin this exciting new chapter. With the IPO process successfully behind us, all of our energy will be dedicated to delivering industry leading service for our customers and improved and sustainable returns for our new and future shareholders from around the world."
Jim Pettigrew, Chairman, added:
"Today marks a very important milestone in our 177 year history as we begin life as an independent listed company. I welcome our new shareholders and thank them for the confidence they have shown in our business. We embark upon this exciting new chapter for CYBG with a strong customer focussed franchise, a large and loyal customer base and a first class management team determined to deliver on our strategy."
NAB’s intention to exit the UK Banking business was first signalled in October 2014 following a fall of nearly 10% in full-year profits, largely due to provisions relating to a misconduct over insurance policies.
During the March 2015 half year, a £21 million fine was issued to Clydesdale Bank in relation to its management of PPI claims.
