The stock market largely took Donald Trump's latest threat on tariffs in stride. The president-elect on Saturday threatened 100% tariffs against a group of developing economies if they act to undermine the U.S. dollar. Trump said he wants the group, headlined by Brazil, Russia, India and China, to promise it won't create a new currency or otherwise try to undercut the U.S. dollar.
The dollar has long been the currency of choice for global trade. Speculation has also been around a long time that other currencies could knock it off its mantle, but no contender has come close.
The U.S. dollar's value rose Monday against several other currencies, but one of its strongest moves likely had less to do with the tariff threats. The euro fell amid a political battle in Paris over the French government's budget. The euro sank 0.7% against the U.S. dollar and broke below $1.05.
