- Polymarket market on probability of 25% tariffs occurring can be found here: https://polymarket.com/event/will-trump-impose-25-tariff-on-mexicocanada?tid=1736543719442. Currently trading at 18% chance of this happening.
- It's hard to grasp what the likelihood is; however, what I will say is that Canadian economic commentators very strongly assume these tariffs do not happen in a meaningful way. To me this suggests tariffs are not priced into the market right now. My personal view is the threat becomes much more effective if you implement them for a limited time, such as Trump doing them for 3 months to get big concessions from Mexico/Canada without much economic impact to the US. American voters will like this (because who doesn't like sticking it to Canada!)
