Donald Trump has given Mexico and Canada a 30-day reprieve from the 25% tariffs levied on their exports (10% on oil) to the United States. The stated motivation for the US to violate the terms of the United States-Mexico-Canada Agreement was that Canada and Mexico needed to do more to quell the flows of fentanyl and undocumented migrants across their borders to the United States. Action by Canada, appointing a Fentanyl Czar, and Mexico, sending 10,000 troops to police the border has negotiated a delay.
But the threat of tariffs still stands over both these major US trading partners, with dire consequences for the US auto industry as well as for their cross-border suppliers. The threat of retaliation by both Canada and Mexico could have seen a full-scale trade war erupt, so a 30-day cooling period to sort out what are real US concerns is welcome.
The tariff action does not stop there, however. China has been hit with an additional 10% on top of already higher tariffs, and Trump has threatened that the European Union is next.
The purpose of this flurry of threats and actions is unclear. Is it a mistaken belief that the US can replace taxes with tariffs, or is it to promote US manufacturing jobs?
Tariffs are just taxes on imports, the direct costs of which will be shared between the US consumer and import using industries, and the exporter. How much the exporter pays depends on a host of factors including what other markets are available to the exporter. For Canada and Mexico’s auto part industries, the answer, at least in the near term, is few if any other markets. But the US auto industry is also dependent on these sources of supply. Sending your suppliers bankrupt is not a sustainable option, so it is a fantasy that the US will not pay at least a substantial portion of the tariff.
If tariffs are aimed at promoting growth in the production of domestic alternatives by increasing the prices of imports, the more successful the strategy the lower the tariff revenue generated. The US has a big diverse economy, so push up the price of imports enough and they will be replaced by domestic production. Whether this expansion in production delivers on the job promise will depend on the cost of labour relative to robots. The point is that success on jobs means less success on tariff revenue. It is madness to claim that tariffs can simultaneously raise revenue and deliver jobs in any significant quantity.
