From Maury Obstfeld, IMF, Chief Economist, today:
…the risk that current trade tensions escalate further—with adverse effects on confidence, asset prices, and investment—is the greatest near-term threat to global growth. Global current account imbalances are set to widen owing to the United States’ relatively high demand growth, possibly exacerbating frictions. The United States has initiated trade actions affecting a broad group of countries, and faces retaliation or retaliatory threats from China, the European Union, its NAFTA partners, and Japan, among others. Our modeling suggests that if current trade policy threats are realized and business confidence falls as a result, global output could be about 0.5 percent below current projections by 2020. As the focus of global retaliation, the United States finds a relatively high share of its exports taxed in global markets in such a broader trade conflict, and it is therefore especially vulnerable.
