Byron Wien, the vice chairman of Blackstone Advisory Partners, who made his name as a strategist at US bank Morgan Stanley has come out with his latest "10 likely surprises for the year", a list he first published 25 years ago.

Wien, who joined Blackstone in September 2009 as a senior adviser analysing economic, political, market and social trends, became one of the most widely read analysts when he was the chief US investment strategist at Morgan Stanley. He made his name after publishing his first list of "surprises for the year" in 1986.
