Weak yen gives boost to exports but also pushes up import prices, leading to lower household incomeFX moves should be determined in a manner that is reflective of fundamentalsShort-term volatile moves are undesirableWill not comment on specific FX levelsDid not get any specific instruction from Takaichi on policyBOJ independence is clearly stipulated by the lawMonetary policy should focus on inflationFiscal policy should focus on addressing its impact on households, firmsHard to conclude whether recent inflation is cost-driven or demand-drivenNeed to watch for both downside risks to growth and upside risks to inflationNot easy to guide policy as we are working with an estimate of underlying inflationAs a reminder, Sato is the second policymaker "planted" at the BOJ by Japan prime minister Takaichi. The first was Toichiro Asada, who voted against the rate hike in June. And despite the mixed remarks above, it is clear that Sato will be more than likely favouring a more dovish policy outlook in general. She will be making her debut in the July meeting next month.Circling back to her comments, the ones on the Japanese yen currency aren't anything that we haven't heard of before. So, carry on as you will. As for the others, they also don't offer too much insight so there really isn't much to scrutinise from the above besides some added caution on guiding monetary policy.
