Union Minister Arun Jaitley today exuded confidence that India will pip Great Britain to become the fifth largest economy in the world next year if economic expansion continues at the projected rate. However, rising international crude oil prices and the global trade war would throw up challenges going forward, he said. "If we keep growing at the rate which is being projected, it is likely that next year we will be the fifth largest economy ahead of Great Britain," Jaitley said in a Facebook post titled 'The Congress Gave Slogans to Rural India - Prime Minister Modi Gave Resources'. "This is in consonance with the rest of the narrative. Being the fastest growing economy for the last four years, we can look at the next decade as one of economic expansion," he added. A latest World Bank report has said that the Indian economy has become world's sixth-biggest economy, pushing France to seventh place. The US tops the list followed by China, Japan, Germany and Britain. The new calculations were arrived on the basis of Indian economy's performance in 2017. India's gross domestic product (GDP) was valued at USD 2.597 trillion at the end of 2017 overtaking the French economy, which was amounted at USD 2.582 trillion last year. "We have already seen a significant move up in India's ranking in the ease of doing business and as a preferred investment destination. Today we stand to be tested in the midst of a global challenge thrown up on account of the international crude oil prices and the trade war," Jaitley said. Crude oil prices, which were around USD 66 a barrel, in April are now hovering around USD 75 a barrel. The Indian economy is estimated to grow at 7-7.5 per cent in the current fiscal, higher than 6.7 per cent growth clocked in 2017-18 fiscal.
