LONDON (Reuters) - JPMorgan said on Friday it continued to think that a Brexit trade deal was more likely than not, though the substance of any deal would be narrow and come with a cost for the United Kingdom. “We continue to think ... that a deal looks more likely than not,” JPMorgan analyst Malcolm Barr said in a note to clients. “The cost of regulatory autonomy for the UK in terms of lost or more difficult access to EU markets looks set to be a high one.”
