Japan's Debt Crisis Unfolds Amidst Strong Stock Market

A debt crisis is unfolding in Japan, according to Robin J Brooks, despite its stock market's strong performance. Brooks argues that Japan's unique initial conditions set it apart from past G10 crises, which were characterized by exchange rate pegs and unsustainably expansionary policies leading to large current account deficits.

The traditional debt crisis model does not apply to Japan due to its steady current account surpluses and high level of public debt. Brooks points out that much of Japan's debt is held domestically, giving the government more discretion to cap yields and shift the pressure from debt service to currency depreciation.

This means that intervention in the form of artificially capping yields cannot stabilize the Yen, as it merely shifts what would be a debt crisis to the currency. The sharp depreciation of the Yen is just a symptom of Japan's too much debt.
