HONG KONG, Nov 2 (Reuters) - Private equity firm Carlyle Group said on Monday it has appointed Aditya Puri, former chief executive officer of India's largest private sector bank, HDFC Bank, as senior adviser.

Puri will advise Carlyle on investment opportunities and portfolio management across Asia, the U.S.-based firm said.

Puri is joining Carlyle after 26 years at HDFC Bank where he was appointed the first CEO when the bank was established in 1994.

He grew HDFC Bank into the largest private sector bank in India with over $210 billion of assets as of end-September and the most valuable bank in India with a market capitalisation of over $90 billion.

Prior to HDFC Bank, Puri spent over 20 years at Citibank overseeing parts of the bank's activities across India, Greece, Saudi Arabia, Hong Kong, Korea, Taiwan and mainland China, with his last role as CEO of Citibank's operations in Malaysia from 1992-1994, Carlyle said.

Carlyle has made investments of around $4.9 billion in financial services by end of September across Asia, excluding Japan, including SBI Card, SBI Life, HDFC Limited, PNB Housing Finance, Repco Home Finance, Edelweiss and IIFL in India. (Reporting by Kane Wu; Editing by Rashmi Aich)
