Wealth of billionaires continues to rise, with the Asian region setting the fastest pace last year, while the minting of such ultra-wealthy persons in the US has decelerated. Some eye-popping data is revealed, making it story of the week.

Figures showed that the world's billionaires are getting richer. Big deal, one might say. But the statistics certainly conveyed how far and fast China's billionaire ranks are expanding, and shed light on the dynamics of the top end of the ultra-high net worth market. It is really no surprise at all that wealth managers are chasing the Asian wealth story - or at least some of them who are able to get scale and profitability right are doing so. The choice of article for this week is a study by UBS and PwC.
