The Japanese government already spends 25% of tax revenue to service outstanding debt (compared to 6% in the US). These costs become even more astonishing when one considers the extremely low rates Japan pays. Ten-year Japanese government bonds now pay less than 0.6%, and five-year yields are now a little more than 0.20%. How much will debt service costs increase if Abe succeeds in pushing inflation to 2.0%? Two percent rates would triple long term borrowing costs. Given the size of its debts, increases of such magnitude could hit Japan with the force of 10 Godzillas.
