There is no definite answer to this question as it depends on various factors such as economic policies, geopolitical events, technological advancements, and global market conditions, among others. However, according to the International Monetary Fund (IMF), India's nominal Gross Domestic Product (GDP) was estimated to be around 3.1 trillion US dollars in 2021.
To become a 10 trillion dollar economy, India would need to sustain a high economic growth rate for a prolonged period. According to some estimates, India could reach the 10 trillion dollar mark by the mid-2030s if it continues to grow at an average annual rate of 7-8%. However, this projection could be affected by various internal and external factors, including political stability, reforms, global trade dynamics, and technological disruptions.
It's also worth noting that the COVID-19 pandemic has had a significant impact on the global economy, including India's. The Indian economy contracted in 2020 due to the pandemic, and the country is currently focusing on recovery and rebuilding. The pace and trajectory of India's economic recovery will also play a crucial role in determining when it could become a 10 trillion dollar economy.
