Japanese yen pushed higher to a three-week high around 152.38 yen after officials hinted at potential currency market intervention. Prime Minister Sanae Takaichi's election win fueled speculation over government action, though currency diplomat Atsushi Mimura declined to confirm intervention while warning against volatility. Australian dollar rose to a fresh three-year high as RBA Governor Michele Bullock's comments increased bets on further rate hikes to combat sticky inflation, with markets pricing in a possible hike by May.

Broader Asian currencies mostly advanced as the dollar took only fleeting support from strong nonfarm payrolls data. The yen's gains persisted despite soft January producer prices, while the Chinese yuan fell to its lowest level since May 2023 amid strong PBOC midpoint fixes. South Korea's won and India's rupee also weakened, though Singapore's dollar remained flat.

Structural challenges like Fed succession uncertainty now dominate FX outlook, with analysts noting the dollar needs additional upside surprises to sustain any rebound. Focus shifts to Friday's U.S. CPI data for further clues on global monetary policy direction.
