I posted on this earlier:
BoJ in the market with bids for:
- JPY 100bln in 1yr-3yr
- JPY 500bln in 3yr-5yr
- JPY 500bln in 5yr-10yr
- JPY 300bln in 10yr-25yr
- JGBs at a fixed-rate, unlimited amount in 5yr-10yr maturities
Part of YCC, see that link above for more detail.
The yield on the 10yrs is back above 0.5%. This is the BOJ's 'ceiling'. Markets don't care.
