Expatriate Indians have an estimated $500 billion of investable assets, a lucrative market for wealth management businesses diversifying from established markets, according to Datamonitor, the research business. The largest concentrations of non-resident Indians live in the US, UK, Canada and Australia. Other significant centres are Hong Kong, Singapore, Qatar and Bahrain, Datamonitor said in a new report. “Strong family ties and an emotional link to their homeland are stoking interest in investments into India itself, which account for between 15 per cent and 25 per cent of NRI portfolios,” the report said. Datamonitor said its surveys among wealth managers in Europe and Asia Pacific showed that NRI investors are typically sophisticated clients who demand the ability to obtain information and deal online as well as receive frequent communications from their investment managers. NRIs also show considerable demand for services such as tax advice, property management and offshore banking, the report added.
