In President Donald Trump’s executive order calling for reciprocal tariffs, he said that their main purpose is to reduce the US trade deficit. Economists have long argued that tariffs have no effect on trade balances.
Trump’s tariffs: Disregarding lessons from history and scenarios and probable outcomes
History is full of evidence that tariffs harm economic performance. This column assesses the two waves of globalisation in modern history and how they were interrupted by barriers to trade. The first wave started in the mid-19th century and lasted until WWI, while the second wave started after WWII and lasted until the Global Crisis of 2008-09. The most likely scenario going forward will feature tariffs around 12-14% on average, a mild recession, and a small hit to US longer-run potential. However, achieving diplomatic normalcy may take years of good US behaviour, and it is unlikely during the Trump administration.

The Weaponized World Economy
When Washington announced a “framework deal” with China in June, it marked a silent shifting of gears in the global political economy. This was not the beginning of U.S. President Donald Trump’s imagined epoch of “liberation” under unilateral American greatness or a return to the Biden administration’s dream of managed great-power rivalry. Instead, it was the true opening of the age of weaponized interdependence, in which the United States is discovering what it is like to have others do unto it as it has eagerly done unto others.

Looking for a “fair” international monetary system
President Trump’s Chief Economic Adviser, Stephen Miran, has claimed that the international monetary system in which the US provides the rest of the world with a safe, liquid asset is “unfair” as it supposedly prevents the US from eliminating its current account deficit. His proposed solution is to lower the value of the dollar through coordinated currency market intervention by foreign central banks. This column finds the idea that there could be lasting reversal of exchange rates following an international currency agreement highly speculative, and argues that a multipolar system would attenuate the Triffin dilemma and provide the US with a deficit-adjustment tool.
