Overall, global wealth grew fastest in the Asia Pacific region last year. North America came in second
Singapore seems modest by some measures: Median income among working households was only about S$5,700 (about US$4,500) in 2010, according to the Singapore Department of Statistics. Yet in this small island nation of only 5 million, known for extravagant shopping, high-end restaurants, and draconian chewing-gum laws, nearly one in every six households has more than $1 million in assets, making it the densest population of wealthy households in the world, according to a new report by Boston Consulting Group. As the financial markets improved last year, global wealth grew in nearly every region in the world. The fastest, at 17.1 percent, came in the Asia Pacific region (excluding Japan), followed by North America at 10.2 percent. "Global wealth is at an all-time high," says BCG Senior Partner Monish Kumar. According to BCG's study, global assets under management grew 8 percent, to $121.8 trillion, about $20 trillion above the level during the depths of the global financial crisis. The number of millionaire households grew 12.2 percent, to 12.5 million, and although they represented only 0.9 percent of all households, they held 39 percent of global wealth. Only Liquid Assets
BCG looked at 62 markets covering more than 98 percent of global GDP and measured assets that included cash deposits, money market funds, listed securities held directly or indirectly through managed investments, and onshore and offshore assets—but not wealth attributed to investors' own businesses, residences, or luxury goods. Wealth in North America, the world's richest region, had the largest dollar-value gain: $3.6 trillion. The U.S. remains home to the most millionaire households—5,220,000 (up 10.7 percent from 4,715,0000 households in 2009)—although the share was only 4.5 percent of all households, BCG data show. While China and India are driving wealth creation in Asia, Singapore also grew at a fast pace. The number of millionaire households in Singapore jumped about 38.6 percent in 2010, to 170,000, from nearly 123,000 in 2009, according to BCG data. The country has had the largest proportion of millionaire households for several years, and the share continues to grow: Singapore's millionaire households increased to 15.5 percent of total households in 2010 from 11.4 percent in 2009. The rise is due to Singapore's expanding economy, which has grown mainly on such exports as consumer electronics and pharmaceuticals, as well as financial services. Real GDP growth averaged 7.1 percent per year from 2004 to 2007, according to the CIA World Factbook and reached nearly 14.7 percent in 2010—faster than China's 10.3 percent growth rate. Not Just Tycoons
Among Singapore's well-known billionaires are Wee Cho Yaw, chairman of United Overseas Bank Group (UOB), as well as the families of the late real estate mogul Ng Teng Fong and financier and hotelier Kho Teck Phuat. Still, many of the country's wealthy are not tycoons but entrepreneurs and affluent immigrants, says Tjun Tang, partner and managing director of BCG in Hong Kong. Other billionaires include philanthropist Richard Chandler in New Zealand and real estate developer Zhong Sheng Jian in China. City-states such as Singapore, along with other small countries and administrative regions with a high density of millionaire households, such as Switzerland, Qatar, and Hong Kong, tend to be hubs of commerce and finance and have greater economic generation within a smaller population, says Tang. Another factor driving wealth: Singapore's investor scheme, which grants permanent residence to certain investors, says Tang. According to the website of Janus Corporate Solutions, people can "invest [their] way to Singapore permanent residence" by investing more than a certain minimum in a new business startup or Global Investor Program-approved fund or in expanding an existing business in Singapore. More Money, But Higher Costs
With this wealthy population comes a relatively high cost of living. In a 2010 cost-of-living survey of 214 cities by consulting firm Mercer, Singapore is the 11th most expensive city in the world for expatriates, on a par with Oslo and more expensive than New York City. Mercer also gave Singapore high scores in its 2010 quality-of-life study of 221 cities: It was the top-scoring Asian city, followed by Tokyo. The economic trends remain a concern around the world, yet BCG expects that with strong capital markets, GDP growth, and increased savings, global wealth will grow at a compound annual growth rate of 5.9 percent through 2015. Singapore has already led with the highest proportion of millionaire households for several years. With the Asia-Pacific region's share of global wealth expected to increase to 23 percent in 2015, from 18 percent in 2010, Tang says, "the trends seem to be in Singapore's favor."
