Asian currencies rose Wednesday as investors weighed the impact of new US tariffs and reacted to Australian inflation data. The Australian dollar surged 0.79% against the dollar after January CPI hit 3.8%, boosting expectations for a Reserve Bank of Australia rate hike. Analysts noted ASEAN economies could benefit from the initial 10% US tariff level, though trade uncertainty persists.

The Japanese yen weakened 0.1% amid reports of political resistance to further BOJ rate hikes, raising intervention concerns. The US dollar index fell 0.25% as markets assessed the tariff fallout.
