At least one Bank of Japan board member mentioned the possibility of making the central bank’s policy-rate outlook more transparent, according to minutes from its September policy meeting released Wednesday.

In their first meeting since a surprise rate increase in July, which may have been at least in part responsible for a market crash, BOJ board members discussed how the bank speaks to the markets.

Some members pointed out that the BOJ needs to more carefully communicate with the public to prevent a divergence between the views of the bank and investors.
