Why Germany’s current-account surplus is bad for the world economy

THE battle-lines are drawn. When the world’s big trading nations convene this week at a G20 summit in Hamburg, the stage is set for a clash between a protectionist America and a free-trading Germany.President Donald Trump has already pulled out of one trade pact, the Trans-Pacific Partnership, and demanded the renegotiation of another, the North American Free-Trade Agreement. He is weighing whether to impose tariffs on steel imports into America, a move that would almost certainly provoke retaliation. The threat of a trade war has hung over the Trump presidency since January. In contrast, Angela Merkel, Germany’s chancellor and the summit’s host, will bang the drum for free trade. In a thinly veiled attack on Mr Trump, she delivered a speech on June 29th condemning the forces of protectionism and isolationism. An imminent free-trade deal between Japan and the European Union will add substance to her rhetoric (see ).
