Pretty much every country fired up their money printers to power through covid.
Here is Canada's money supply:
Every other country did the same thing. Although I think governments, companies, and individuals are stumbling through the shock of such an unprecedented injection of supply... Ultimately IMO this is a global "hangover" from covid money printing.
This is why I'm hesitant to over-attribute current economic conditions to things like "approaching limits of growth". To me, those are zebras. Unprecedented monetary supply manipulation are horses. When I hear hoofbeats, my first guess is the horses.
Oh sure for current inflation but everything post 2000 is a house of cards. stock prices completely deviated from earnings as they turned into value holds and income was pulled out via debt.
Ok I'll bite. How does Canadian policy cause global inflation?
The only angle that I can think of is that we've had a larger impact on carbon production than most other countries, and at least when it comes to global food inflation, climate change is having a noticable impact. So one might be able to argue that our role in climate change is causing food inflation. But I doubt anyone has actually done any peer reviewed studies on that so it's likely just assumptions at best.
I do think all levels of government have made some bad decisions that are unique to Canada, but yes they are. Our housing crisis is probably the worst example.
