NEW YORK/LONDON (Reuters) -The U.S. dollar rose against most major currencies including the Swiss franc and the euro on Thursday, as investors consolidated positions after selling the greenback for most of this week, but the outlook remained weak amid concerns about slowing growth arising from the Trump administration's trade policies. U.S. President Donald Trump threatened to impose a 200% tariff on wine, cognac and other alcohol imports from Europe, opening a new front in a global trade war that has roiled financial markets and raised recession fears. Labor Department data on Thursday showed that U.S. producer prices were unexpectedly unchanged on a monthly basis in February, but the prospects of tariffs are unlikely to keep prices down in the coming months.
