Airtel Payments Bank (APB), an online banking subsidiary of Bharti Airtel, the second-largest telecom operator in the country, had a great performance in 2021. APB benefitted a lot from the Reserve Bank of India’s (RBI) decision of increasing the day-end savings limit to Rs 2 lakh last year. Earlier, the limit was Rs 1 lakh. As customers or users could save more money in their APB online savings account, the customer deposits went up to Rs 1,000 crore in 2021.
