Over three quarters of millionaires feel Brexit will be beneficial for their finances, according to a survey carried out by UBS Wealth Management.
The UBS Investor Watch survey questioned nearly 3,000 millionaires globally, including 400 in the UK.
It found 82% of respondents felt we are living through "the most unpredictable age in history" due to issues such as Brexit, the policies of US President Donald Trump and rising tensions in North Korea.
Some 85% believed these uncertainties were a risk to their wealth; double the number who view this environment as an opportunity.
But, despite this, some 78% thought Brexit would have a beneficial effect on their financial planning in the long term and just over half expect their finances to improve over the next 12 months.
Some 85% felt confident they were able to assess their own financial risks and believe they can find a safe place to invest their money. This included holding cash or investing in their domestic market.
Some 86% saw physical assets such as property as a safe place for their wealth, with over a third investing more than 50% of their wealth in this area.
There were also worries about short-termism, particularly among younger respondents. Over 80% of those surveyed under-35 said they found themselves distracted by short-term risks compared to 74% for all respondents. It was not just their own investments, as 79% believed elected governments only reacted to short-term events.
Nick Tucker, head of UK domestic at UBS Wealth Management, said: "After a year of Brexit, high-profile shocks and global tensions, most believe we live in a very unpredictable age. Political, economic, societal and financial risks are all prominent in people's minds.
"In response, we see evidence of short-termism creeping in, people reacting to each event as uncertainty grows. Investing on your own doorstep can be tempting in this climate. Holding onto cash can feel safer, even as it erodes your wealth in real terms. Although confidence remains high, neither approach is likely to work well in the long term."
