Japan has just announced a $490 billion support package to families and small businesses. This sizeable support structure is funded by more Japanese debt. While a few economists issue cries of concern about the size of the debt and the prospect of inflation, most economists and the Japanese lawmakers are unconcerned. With interest rates at 0% for 30 years, who could blame them?
Yet the interesting part is that Japan's relative debt to GDP dwarfs that of the US. If more debt creates more inflation, why are these stimulus packages in Japan not creating more inflation? Yes, it is true that less immigration occurs in Japan and yes, it is also true that birthrates are lower. However, these factors do not seem capable of driving such an extraordinary difference in the mantra "more debt, more inflation."
Of course, no one truly knows the answer. That's part of the fun in opining on this process as opposed to advances in quantum computing or genetic engineering. However, for my part, I continue to see that more debt at some high level - such at 100% debt to GDP - slows the economy. In the famous equation that inflation equals money times velocity, it appears that increased money is thwarted by the slowing effects of massive debt on velocity numbers. The only chance of offset would be to use debt to fund productivity improvements, but increased productivity is incredibly unpopular - as we are seeing in India.
