| 200% | Japan's 20-year bond sale sees strongest demand on record 财政可持续性 · 第 4 张术语卡 | Japan's gross debt is well above 200% of GDP; every extra percentage point on JGB yields feeds straight into the budget. 判断可持续性,看的不是债务总量,而是三个比值的赛跑:利率(r)与名义增长率(g)。r 低于 g 时,债务/GDP 会自然下降,叫「被动去杠杆」;r 高于 g 时,即使不再新增赤字,债务占比也会往上走。日本过去二十多年靠的是 r 接近零,如今 10 年期到了 3%,这个前提第一次松动了——这才是「高市财政」让市场紧张的技术原因。 |
