Rich Asians got richer faster than anyone else in the world last year. Wealth assets held by high-net-worth individuals in the Asia-Pacific region jumped almost 15 percent to $21.6 trillion in 2017, according to a Capgemini SE report released Tuesday. Accelerating economic growth and equity market rallies helped push the global total to a record $70.2 trillion, the World Wealth Report showed. The rising number of millionaires in Asia is prompting financial firms from Credit Suisse Group AG to DBS Group Holdings Ltd. to expand private banking operations throughout the region. While Japan and China contributed the bulk of Asia\u2019s wealth last year, India topped the global chart when it came to the growth rate. \u201cEmerging markets in Asia, such as China and India, are going to be the engine of growth,\u201d said David Wilson, the consulting firm\u2019s head of Asia wealth management. Global wealth is on course to exceed $100 trillion by 2025, according to the report, which defines high-net-worth individuals as those with at least $1 million in investable assets.
