It’s inevitable that the US will follow suit with Negative interest rates. The crazy thing is that those in power have a GOAL to make things more and more expensive for average Americans (AKA 2% annual inflation). Cell phones and other tech have been dropping in price like crazy (a good thing when you want a $5 cell phone!), but when it comes to food, rent, healthcare, and basic survival needs, decreasing prices in that is “bad.”
For the US, I predict more rounds of QE to artificially prop the economy, and if need be, NIRP. If the Fed allows the economy to tank, then the Republicans will take the Presidency.
