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.
There is no question who has the better of this argument. Mr Trump’s doctrine that trade must be balanced to be fair is economically illiterate. His belief that tariffs will level the playing field is naive and dangerous: they would shrink prosperity for all. But in one respect, at least, Mr Trump has grasped an inconvenient truth. He has admonished Germany for its trade surplus, which stood at almost $300bn last year, the world’s largest (China’s hoard was a mere $200bn). His threatened solution – to put a stop to sales of German cars – may be self-defeating, but the fact is that Germany saves too much and spends too little. And the size and persistence of Germany’s savings hoard makes it an awkward defender of free trade.
At bottom, a trade surplus is an excess of national saving over domestic investment. In Germany’s case, this is not the result of a mercantilist government policy, as some foreigners complain. Nor, as German officials often insist, does it reflect the urgent need for an ageing society to save more. The rate of household saving has been stable, if high, for years; the increase in national saving has come from firms and the government.
Underlying Germany’s surplus is a decades-old accord between business and unions in favour of wage restraint to keep export industries competitive. Such moderation served Germany’s export-led economy well through its postwar recovery and beyond. It is an instinct that helps explain Germany’s transformation since the late 1990s from Europe’s sick man to today’s muscle-bound champion.
