The power of relationships continues to be the key differentiator for NAB’s Corporate and Institutional Bank, according to a survey which polls more than 670 large Australia-based corporates and institutions.

Positive client feedback was reflected in NAB’s Net Promoter Score (NPS), which sits at +43, signalling strong customer loyalty and satisfaction with the company¹.

Survey participants also endorsed NAB by maintaining its long-standing leadership position in the Relationship Strength Index (RSI) for Debt Capital Markets now 11 years in a row² and also in the inaugural Trade Survey³.

NAB Group Executive, Corporate and Institutional Banking, Cathryn Carver thanked customers for the feedback and opportunity to understand how NAB can improve to better serve and support their businesses.

“Customer feedback powers great partnerships. This year saw record participation to the survey across the financial services industry. This means customers have something to say. We all have a great opportunity to lift customer experience across the sector so that all customers benefit and thrive”.

“We know there is more that can be done in our quest to be the most customer-centric company in Australia and New Zealand. We will use these insights to do just that. We are listening and we are acting.”

Survey results also recognised NAB’s bankers and specialists as being the best of the best, with their advice on various products, including the use of interest rate risk management and service for large deposits¹.

“We have an exceptional client-focussed team in Corporate and Institutional Banking, who pride themselves on achieving the best outcomes for their clients,” Ms Carver said.

“We know that competition is fierce so we’re continuing to innovate and evolve our client offering and products.

“These insights and feedback will help accelerate this and ensure we continue delivering impactful outcomes for our valued clients.”
