We will return to discuss the implications of how big the debt level is, but the graph itself should serve to focus the mind. The March 31 level was 350% of GDP. The previous peak occurred in 1933, during the Great Depression, at just under 270% of GDP. Note that the peak was reached due to the start of the rapid fall in GDP taking hold faster than debts were written off, a dynamic not in operation now. So the comparable level to our situation is in fact lower than the 270% peak.
An additional bit of cheery news comes from reader Bjomar: Japan’s total debt to GDP in 1990 was roughly 250% (it took some triangulating among this, this, and this source, his interpolation of corporate debt at 100-140% of GDP, household at 65%, and government at 60%). And unlike us, Japan had a very high saving rate, so its net debt would have been less alarming.
