At present, ten-year JGBs have fallen to slightly above 0.5 percent and even 30-year JGBs are below 1.0 percent. The average maturity of newly issued JGBs in Japan is currently about five years.
The fact that yields on five-year JGBs are in the range of 0.1 to 0.2 percent indicates that the government has already been raising funds at an interest rate of virtually zero percent.
