The bazooka diplomacy of Trump’s tariffs
President Trump’s recent pronouncements on tariffs have received considerable attention from analysts, policymakers, and commentators. This column takes a step back and considers some of the broader arguments for raising tariffs – revenue, restriction, and reciprocity – and the potential repercussions. Even if Trump does not proceed with (all of) the announced tariffs, the increased uncertainty is likely to put off firms from trading with or from the US, lowering US exports and imports beyond the imposition of higher tariffs. In the longer term, we can expect a gradual decoupling of trade between the US and other countries.

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.

Why higher tariffs won’t shrink the trade deficit
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.

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.
