Noahpinion's 2025 Year in Review

Five years ago, I made the (questionable) decision to launch my Substack over Thanksgiving weekend. So every Thanksgiving or thereabouts, I do a roundup of seven important themes from the past year, along with a few themes to watch for in the upcoming year. Here’s last year’s edition. The links below are all links to other posts I wrote over the past 12 months, so you can use this post as a reference for what I wrote about in 2025.

I’d also like to thank everyone for reading and supporting Noahpinion. A year ago this blog had 280,000 readers; now it has 414,000. I never expected my blog to get that big, and I’m incredibly grateful to all of you for helping to make that happen. Please remember to recommend Noahpinion to your friends, family, and coworkers! I also published a book this past year, though so far it’s only in Japanese; this upcoming year I’m going to write an English-language book about macroeconomics, so be on the lookout for that.

Anyway, here are the seven themes for 2025.

On April 2, which he dubbed “Liberation Day”, Trump announced truly enormous tariffs on almost all of the countries in the world. Many of these tariffs were eventually walked back, sometimes after “deals” in which other countries made various promises to the U.S. and/or to Trump and his family. Thankfully, none of the worst-case scenarios have yet reared their heads.

But some tariffs remained in place, and these tended to be tariffs on America’s allies rather than on China. And general uncertainty about future tariffs has exploded. This, along with worries about U.S. political unrest and national debt, has led to a depreciation of the dollar as some investors hedged their bets by moving money out of the country.

The tariffs haven’t yet tanked the economy or raised inflation, but they’re exerting a corrosive influence on the economy, pushing up prices, weighing on employment, and hurting the manufacturing sector. This was entirely predictable; economists have long understood that tariffs on intermediate goods hurt manufacturing by disrupting and shrinking supply chains. Trump’s team, unfortunately, makes it a point of pride not to listen to economists, instead choosing to invent a blizzard of
