India's credit card market crossed the 119-million mark in March, but the gains are far from evenly distributed. Data released by the Reserve Bank of India shows that four lenders-HDFC Bank, SBI Cards, ICICI Bank and Axis Bank- continue to dominate the market, even as the competitive dynamics within that group are shifting. HDFC Bank is pulling away from the pack. The largest private sector lender in the country increased its share of outstanding cards to 22.2% in March from 21.7% a year earlier, while its dominance in spending intensified, with an increase in transaction value share to 29.8%, underscoring its ability to drive higher usage among its existing cardholders.
