For Japan to pay down its net debt even to 80% of GDP by 2030, it would have to turn a 6%-of-GDP primary budget deficit (before interest payments on existing debt) in 2014 into a 5.6%-of-GDP surplus by 2020, and maintain that surplus throughout the 2020s.
Para devolver su deuda neta en 2030, incluso al 80% del PIB, Japón debería convertir el déficit primario (antes del pago de intereses de la deuda actual) de 2014, igual al 6% del PIB, en un superávit del 5,6% del PIB en 2020, y mantenerlo el resto de la década.
