BOJ Hawkishness Combines with Soft Dollar Sentiment to Boost Yen

The yen has extended its gains against the US dollar, pushing USD/JPY below 157.70 and continuing a sharp move that began overnight during Wednesday's US session.

Traders and analysts attribute this to genuine hawkish repricing of domestic BOJ rate expectations rather than official intervention from Tokyo.

BOJ board member Hajime Takata recently suggested the central bank should conduct rate hikes nimbly to counter intensifying inflationary pressures, a sentiment echoed by Citi as the strongest messaging yet from the board reintroducing the idea of an expedited hike trajectory.

The yen's surge is also influenced by softer dollar sentiment, partly due to less hawkish comments from New York Fed President John Williams who framed the Treasury yield surge as a function of economic strength rather than dysfunction and declined to commit to a September rate hike.
