Oct 9 (Reuters) - Global wealth has risen by 68 percent over the past 10 years to reach a new all-time high of $241 trillion and the United States accounts for nearly three quarters of the increase, Credit Suisse said in its World Wealth Report.
Average global wealth has hit a peak of $51,600 per adult but this is spread very unevenly, with the richest 10 percent owning 86 percent of the wealth, analysts at the Credit Suisse Research Institute said.
The top 1 percent alone own 46 percent of all global assets.
Global wealth will jump a further 40 percent by 2018 to reach $334 trillion, the report added.
The richest nations, with wealth per adult of more than $100,000, are concentrated in North America, Western Europe and among the rich Asia-Pacific and Middle Eastern countries.
They are headed by Switzerland, where average adult wealth amounts to $513,000, followed by Australia ($403,000), Norway ($380,000) and Luxembourg ($315,000).
However, two thirds of adults in the world have assets worth less than $10,000 and together account for just 3 percent of global wealth.
