As Group Head of Treasury at HDFC Bank, Ashish Parthasarthy oversees more than just market operations. His portfolio spans treasury, infrastructure, digital channels and branch banking, making him a key voice in shaping the bank’s financial architecture. A board member of FIMMDA, Parthasarthy is also among the last few from the bank’s founding team still in an executive role.In this conversation with market veteran Manoj Rane, he lays out how HDFC Bank’s early institutional choices have helped it avoid pitfalls that have tripped up others. At the centre of this discipline is a structural separation between risk-taking and risk-approving teams, something Parthasarthy says was borrowed consciously from the multinational bank playbook and embedded from day one.
