Welcome everyone to Inside Economics, coming to you from Davos.
I'm Rachana Shanbhogue, the Economist's Business Affairs Editor.
On the far side is Henry Curr, our Economics Editor and my co-host.
Venezuela, Greenland, whatever else comes next,
Donald Trump is turning geopolitics on its head,
straining long-established relationships and alliances,
and with threats and tariffs abroad,
America seems intent on undermining its hegemony.
So it's a natural time to ask whether this is going to
translate across to America's financial dominance,
and whether changes are coming for the financial landscape as well.
To discuss this, we're very pleased to be joined by Ken Rogoff and Gita Gopinath.
Gita, until last year, was the First Deputy Managing Director of the IMF and is now a professor at Harvard.
Ken, also of Harvard, also previously of the IMF,
and an author of a very well-timed book published last year
on the dollar, Our Dollar, Your Problem.
Thank you for being with us.
So if we start first, Henry, with what's happened to the dollar,
that seems a good place for the discussion.
Talk us through what's happened over the past year.
