Thesis at the time
Strongly BearishThe Bank of Japan has been printing ~20% of the monetary base per year for ~5 years. Japan's national debt is over 250% of GDP and interest on the debt is already over 9% of the budget at a 1% average rate. At 3% rates, debt service would consume ~28% of the budget — unsustainable. The BOJ will keep printing to cap rates and crash the yen in doing so. This is Mark's 'desert island' set-it-and-forget-it trade, on since late 2012 from ~79.
Key arguments
- BOJ printing ~20% of monetary base per year (non-compounding) — structurally destroys the currency
- Japan debt/GDP over 250%; interest at 1% is already 9% of national budget
- A 3% normalized rate would push debt service to ~28% of the budget — unsustainable, forces continued monetization
- Historical context: USD/JPY was 250 in the 1980s and 300 in the 1970s — no technical reason it can't return there
- Competitive devaluation framework — Japan printing harder than the US even during QE3, now the Fed is tightening while BOJ is not
Counter-arguments acknowledged
- Bernanke's thesis that synchronized global devaluation prevents any one currency from collapsing — Mark dismisses Bernanke as 'an idiot'
