There were rumours that NAB was looking to offload its UK banking subsidiaries, but the bank issued a trading update last month in which its chief executive officer Cameron Clyne, confirmed that it was not in the interest of shareholders to exit its UK position.
Lynne Peacock, chief executive, NAG UK, says is strategy remains unchanged.
She says: “We have an enduring commitment to supporting our customers in these challenging times.
“Almost £2bn of new lending has been advanced to business and mortgage customers at a time when they have needed it most. Business lending was up over 14% and mortgage lending has grown by over 4% demonstrating our ongoing support for the communities in which we operate.
“Our strategy remains unchanged. We continue to drive ever-greater efficiency from our operations and have elected to maintain a very conservative liquidity and capital position.
“While this has had an inevitable effect on bank profit, the compelling security and strength of our brands has attracted an extra £2.6 billion of deposits compared with the prior corresponding period.
“This is a creditable performance from a good bank in exceptionally poor market conditions.
“We continue to be ahead of peers on most key indicators with a strong underlying business that remains profitable, despite the impact of the trading environment all UK banks operate in.
“We remain in the best possible shape and are well positioned to fully capitalise on future growth opportunities.”
