The Indian retail industry has emerged as one of the fastest growing industries, accounting for over 10% of GDP. The market size is expected to reach $1.3 trillion by 2020 from $600 billion in 2015 growing at 12% annually. Modern trade is projected to expand at 20% per year. E-commerce sales are forecasted to reach $55 billion by 2018 and $220 billion by 2025. The growth is driven by rising incomes, urbanization, foreign investment, and the government's support through initiatives like GST. Both organized and unorganized retailers will need to collaborate to tap opportunities in rural markets and leverage digital channels.
