Overview
Total assets on the Bank of Japan's balance sheet, in billions of yen, reported monthly. The BOJ has historically been the most aggressive G7 central bank in expanding its balance sheet relative to GDP, owning the majority of outstanding Japanese government bonds and a meaningful share of the equity ETF market.
Interpretation
- Rising BOJ assets: ongoing yield-curve control and monetary easing — historically supportive for global liquidity.
- Falling BOJ assets: tightening of Japanese monetary policy, often coincident with yen strengthening.
- Sudden moves are rare but typically signal a regime change in YCC or inflation policy.
