Is there a way for a private individual investor to bet on Japanese Government bonds interest rate going up in the coming years?
When the interest rate of a bond goes up, the price of the bond goes down
So, to bet that the interest rate going up, you just have to short the bond itself.
For that, you have to find a broker that allows you to trade Japanese government bonds.
I don't want to advertise any broker in particular, but I know that AvaFx allows you to trade Japanese governement bonds.
I do not have time (yet) to read, understand and summarize the strategy, nor do I endorse it. The title is indeed hyped. I just posted the link for those who are interested in the subject. Feel free to update my post with a summary, or propose a better answer.
