Imagine a world where you could borrow money at an interest rate between 0% to 1%, and invest that in a treasury note (i.e. ‚Äúrisk-free‚ÄĚ) returning 3% to 4%. Would you do it? The answer‚Ķ probably yes. And believe it or not, that‚Äôs how the world functioned for many years. Japan‚Äôs interest rate was far below that of the US, Canada, the UK, and many other countries for decades, and governments, institutions, and individuals all over the world made the most of it.
