After the 2008 crisis, world leaders agreed that a global approach was needed to financial regulation. Donald Trump's win puts this consensus, along with other global initiatives that have the US as a key player, in question.

First in the firing line, specialists in Europe and the US reckon, is the Dodd-Frank Act that has overhauled US derivatives markets in line with pledges by the G20 to get derivatives cleared, reported and traded on electronic platforms where appropriate. As in many areas, Trump's position isn't fully clear. But speaking to Fox in October he was adamant that "we have to get rid of Dodd-Frank".
