Analysis

By total government debt, Mongolia ranks 118th and Japan 3rd among the 135 sovereigns tracked on this site.

On a per-citizen basis the picture can look different from the nominal totals: a resident's notional share of the government debt in Japan is roughly 19.5× that in Mongolia ($71,304 vs $3,657 per person).

The debt-to-GDP picture is asymmetric here: Japan sits at 205% of GDP, well above Mongolia's 45%, meaning Japan owes far more relative to the size of its own economy — even where the nominal, dollar-for-dollar comparison above suggests otherwise.

The gap between them is narrowing: Mongolia's debt is growing faster in dollar terms ($73/sec vs −$15K/sec for Japan), closing the difference by roughly $1,271,894,400 per day. At that pace — and holding both growth rates constant, a simplification, since real-world rates shift with fiscal policy — the two would reach a similar total in roughly 19 years.

Scale is part of the story too: Japan's population (123M) is about 33.8× Mongolia's (4M), which is part of why the nominal and per-capita comparisons above can point in different directions — a government's debt load scales loosely with the size of both its economy and its population, not either alone.

Mongolia and Japan are both grouped under this site's “Asia-Pacific” region, so this is, in effect, an intra-regional comparison as well.
