Customers rank NAB as Australia’s leading corporate and institutional relationship bank¹

• NAB ranked number one for relationship strength across the four studies of the independent 2026 Crisil Coalition Greenwich Voice of Client studies.  
• Status as the leading relationship bank underscores NAB’s customer-centric strategy. 
• As volatile conditions persist, customers are seeking trusted expertise to navigate conditions

NAB has been recognised as Australia’s leading corporate and institutional relationship bank in the 2026 Coalition Greenwich Voice of Client studies¹, an independent assessment based on direct feedback from customers. 

The results position NAB as a market leader for relationship strength across relationship banking, transactional banking, trade and debt capital markets. 

NAB Group Executive Corporate and Institutional Banking, Cathryn Carver, said the result was a powerful endorsement of the bank’s strategy and the strength of its customer relationships. 

“We are a relationship bank so recognition like this really matters because it’s based on direct feedback from customers about their experience working with their banks,” Ms Carver said. 

“Relationships are always important, but they’re particularly critical in challenging and uncertain times like we are experiencing today. Businesses of all shapes and sizes are looking to their bank for expert advice and support as they adapt and navigate those conditions. 

“As Australia’s biggest business bank, and with wide-reaching corporate and institutional and personal banking divisions, we have a deep understanding of what our customers need and these results reinforce that we’re delivering for our customers when they need us. 

“At the same time, our investment in innovation and digital banking including liquidity management, FX and cross-border payments is making it easier for customers to do business with us.” 

The Coalition Greenwich survey is widely regarded as a leading benchmark of performance in corporate and institutional banking, capturing detailed customer feedback on products, service and relationship management. 

Following the recent Roy Morgan Major Bank Customer Satisfaction recognition, the Coalition Greenwich results demonstrate continued progress in NAB’s ambition to be the most customer-centric company in Australia and New Zealand. 

“We’ll continue to earn our customers’ trust by listening deeply, partnering closely and delivering advice, insights and creative solutions² to help them navigate the current economic environment,” Ms Carver said.
