India recorded the largest gains -- for the region and globally -- for HNWI (high networth individuals) population (26.3 per cent) and wealth (28.2 per cent).
"The election of a popular reform minded prime minister helped to boost investor confidence and contributed to strong performance in the stock market, with a 21.9 per cent increase in the MSCI Index. Lower oil prices helped reduce country's budget deficit and retail inflation fell considerably," the report said.
According to the 'World Wealth Report 2015', released by Capgemini and RBC Wealth Management, there were 1,98,000 HNWIs in India in 2014, while in 2013 the figure stood at 1,56,000.
India has been raked 11th in the list of countries with highest number of HNWI population. The US topped the chart with 43,51,000 millionaires, followed by Japan 24,52,000, Germany (11,41,000) and China (8,90,000) in the second, third and fourth place respectively.

Since 2006, Asia Pacific dominated HNWI growth and of the USD 7.4 trillion of HNWI wealth added in Asia Pacific since 2006, India and China accounted for an impressive 43 per cent.
"Continued growth is expected to result in India and China holding over 10 per cent of all global HNWI wealth by 2017," the report said.
China and India, in particular, have propelled Asia-Pacific HNWI wealth growth in recent years and are expected to continue to act as key drivers, both in the region and globally.
Looking further ahead, HNWI wealth is expected to expand more in Asia-Pacific than in any other region of the world with much of the new wealth expected to come from the emerging economies of China, India, Indonesia, and Thailand, the report said.
