The highlight - or at any rate the focus - of the Dollar's week was Donald Trump's press conference on Wednesday, his first and only as President-elect. For supporters of the Dollar it was a sobering affair, revolving mainly around Mr Trump's alleged business and leisure interests. There was no mention of the stimulative tax and spending measures upon which they had been pinning their hopes. The Dollar lost a third of a cent to the Euro.

It gained two and a quarter cents against the pound, which took three palpable hits from two Prime Ministers. Last Sunday Theresa May said Britain cannot keep "bits" of the EU (such as the single market) when it leaves. The following day Germany's Angela Merkel said much the same thing. Then on Thursday Sterling fell again when Downing Street announced that Ms May will be making a speech about Brexit on Tuesday.
