Amid the tumult of the WEF in Davos this week, some investors are leading the way by ditching US government bonds

There is a way to file for divorce from Donald Trump and Europe needs to grab the opportunity.

To the public it will look as if nothing has changed. But behind the scenes the EU and the UK could close the joint bank account and cut up the credit cards, or at least set in motion a form of financial separation that limits the power of a controlling former partner.

It won’t be easy to walk away and it won’t be quick. But a degree of separation is necessary and, crucially, achievable.

As a tumultuous week in the Swiss Alps ends with a reprieve for Greenland and there is talk of a post-Davos peace deal for Ukraine, maybe some believe a mix of distraction and appeasement can placate the US president. Or that midterm elections in the US will lasso Trump and tame him permanently.
