Lydia Tomkiw – Come 2015, Indonesia will be home to 99,000 wealthy individuals with a combined fortune worth $487 billion, according to a report.

The Asia Wealth Report, published by the Julius Baer Group and CLSA Asia-Pacific Markets, predicted that Indonesia will see a 25 percent increase over a five-year period in terms of the number of High Net Worth Individuals (HNWI), individuals with $1 million or more in investable assets excluding their primary residence. This is the highest growth rate predicted among the 10 Asian economies in the report.

The report covered Indonesia, China, India, Thailand, South Korea, Taiwan, Hong Kong, Singapore, the Philippines and Malaysia.

The number of HNWI will continue to grow across Asia, the report suggested. The estimated 1.16 million HNWI in 2010 will more than double to 2.82 million by 2015 with their wealth almost tripling to $15.81 trillion.

Economic giant China will have an estimated 1.4 million HNWI with a stock wealth of $8.76 trillion by 2015. China had 502,000 millionaires last year alone.

The report found that currency appreciation is key and varying rates of currencies could create 600,000 new HNWI across Asia by 2015.

China and India will play key economic roles contributing 40 percent of the global growth rate in 2011 and 2012. "The current deterioration in global economic conditions will see further supportive, pro-growth policies from China in the months ahead," the news release said.
