The sixth annual study, titled 'Innovation in Retail Banking 2014', surveyed over 100 retail banks around the world.
The report found that more banks in fast growing and rapidly developing markets are displaying greater ambition for becoming innovation leaders in delivering superior customer value.
They are doing this by investing more in research and development compared to their peers in mature markets, the report added.
After technology companies, the most significant threat is perceived to come from telcos and from start-ups, it added.

As part of their innovation strategies, 26 per cent of banks surveyed said they are investing in start-ups.
Many banks organise their innovation activities around specific themes. Mobility is currently the most important theme with 88 per cent of banks rating the importance as 'high', followed closely by Big Data (67 per cent) and 'Social Channels (63 per cent).
"In times of continued pressure on profitability, there is no let-up in the demand from customers for innovative products and services. Many banks in rapidly growing emerging markets, who are used to generating profits from customers with smaller transaction values, are at the forefront of innovation in retail banking," Infosys Senior Vice President and Global Head of Finacle Michael Reh said.
Lessons on innovation from these banks could be extremely valuable to financial institutions around the world as they compete with new players in the market, Reh added.
