HDFC Bank is expected to double its tech spending as it looks to compete with peers and improve digital capabilities. From 8-9% as a percentage of opex, spending will increase to 18-20%, said Suresh Ganapathy, Association Director at Macquarie Capital. The cost-income ratio is also expected to go up from 36% to 40%. With analysts viewing this as a positive step, the focus will be on decoupling legacy systems and improving digital capabilities.
