While the world is gripped in yet another great distraction over the great “will he, won’t he” start World War III debate, things that are unsustainable remain unsustainable. Such as Japan’s debt, and specifically the amount of cash interest that the nation with the 230% debt/GDP (and rising interest rates) will have to pay to service its gargantuan balance sheet. According to a document seen by Reuters, Japan expects to spend a record $257 billion to service its debt during the next fiscal year. The amount to be allocated for debt-servicing for the year that will begin on April 1 is nearly as large as the gross domestic product of Singapore, which the World Bank put at $275 billion at the end of 2012. More disturbing, this is a 14% increase in the debt interest cost in just one year. And yes, it is unsustainable absent an epic inflationary episode to “inflate away the debt”, something that Abenomics has so far failed in achieving despite some hopeful early glimmers in crushing the Yen.
