Why Japan isn’t broke yet

Video summary

Japan’s net debt fell from 118% to 77% of GDP as foreign investments and a weaker yen boosted its assets—but inflation threatens the strategy.

Japan’s headline government debt reached 226% of GDP in 2023, but economists Tim Dou and Stijn Lustig argue that this misses the public sector’s vast financial assets. After accounting for assets and liabilities across government bodies, the video puts Japan’s net debt at about 77% of GDP, below that of the US and UK. It traces Japan’s transformation from a postwar public banking system, funded through Japan Post, into a global investor borrowing cheaply in yen and buying foreign assets. A weaker yen and rising overseas markets helped cut net debt from 118% of GDP in 2012 to 77% in 2024. But the gains were partly luck, and the strategy faces geopolitical risks and inflation: higher Japanese interest rates could make borrowing costlier and undermine the carry trade. With prices already rising after decades of stability, Japan may have to choose between containing inflation and keeping its debt strategy afloat.
