BOJ’s Masu: Must Watch Weak Yen’s Impact on Inflation

Masu's remark matters less as a policy signal than as evidence that the board is still framing yen weakness through an inflation lens, which keeps currency moves inside the reaction function rather than treating them as external noise. It lands on a board that has already been parsing sticky domestic prices, so the practical question is whether this concern hardens into a policy response or remains rhetorical. The yen's pass-through into consumer prices, and whether other board members echo Masu, is the open thread.
