You know how we always say follow the bond market if you want to know where an economy’s going?
With that in mind, consider the yield on the Japanese long bond today: 0.458 percent. So when you lend the Japanese government money for 30 years, you’ll get twice-yearly payments equal to 0.458 percent of what you put up. So basically nothing.
It’s also worth noting that if you buy the Japanese ten-year bond, you actually have to pay for the privilege.
