The Tariff Exemption Behind the AI Boom Data Centers get Tariff-Free Imports. Why Shouldn't we All?

NEW from me:

In his 2nd term, Trump has pursued the largest trade war in modern US history—with 1 glaring omission. Computer imports are almost entirely exempt from tariffs

It's a special carveout that AI companies are now reliant on for their data center buildout🧵

How Michael Sabia can make Ottawa move fast and build things Canada’s top bureaucrat is expected to light a fire under a federal public service accustomed to moving more slowly than the moment demands

Great article by @aradwanski.bsky.social that is ostensibly about Michael Sabia, but is really about the case for broader public sector reform. We need a serious effort to renew our state capacity if we truly want to get things done in Canada. www.theglobeandmail.com/business/art...

Over the last free months Canada has upped its border security, agreed to participate in the Golden Dome, and spend 5% of GDP on defence and it basically all means nothing. No agreement will be stable or secure, even if we can eventually reach one. The new normal in Canada-US relations.

a timeline graph of Trump's 2nd-Term tariffs

The court ruling against many of Trump's tariffs today would lower US overall tariff rates by roughly 10%, only leaving the tariffs on cars, steel, & aluminum

If it holds (a very big if) tariffs would drop to the lowest rate since March & importers would get retroactive relief

A US deficit of $2.3 trillion is about 7.5% of expected US GDP in 2026. Canada is in the range of 2% defict/GDP.

Their 10 year bond is about 4.5%; ours is about 3.5%.
