Just a few days after his retirement at HDFC Bank, Aditya Puri has picked up a new role. Carlyle Group has appointed the former chief executive of India's largest private sector bank as a senior adviser in Asia as it seeks to source new investment opportunities and strengthen its portfolio companies.

Puri will advise the Carlyle team on investment opportunities across Asia. Carlyle's Asia portfolio includes McDonald's China, an investment in the State Bank of India's credit card business and a stake in pharmaceutical group Piramal Pharma.

Puri was appointed as the first CEO of HDFC Bank when it was established in 1994. Under his stewardship, HDFC became the largest private sector bank with over $210 billion of assets as on 30 September and the country's most valuable bank by market capitalisation. The 70-year-old had to retire from HDFC as per the Reserve Bank of India's upper age limit for bank officials.
