Asian currencies traded mixed against the dollar on Wednesday, finding support from renewed risk appetite. OCBC Group Research strategist Christopher Wong noted that hopes for a U.S.-Iran deal, combined with a softer dollar and lower Treasury yields, provided breathing room for regional currencies after recent pressure.

The dollar rose 0.2% to 1,500.10 Korean won but slipped 0.25% to 3.9580 Malaysian ringgit, holding steady at 1.2778 Singapore dollars. President Trump's comments that Iran negotiations reached final stages while maintaining military pressure added to the cautious optimism across trading desks.

In currency pair movements, the Australian dollar-yen showed risk-on momentum according to StoneX analyst Matt Simpson. The pair approached weekly pivot points, with potential to test 114 yen if Australian jobs data holds firm. AUD traded 0.1% lower at 113.56 yen, but technical indicators suggest further upside potential.

Market participants remain focused on geopolitical developments and upcoming economic data, which could determine whether this risk-on tone persists or reverses.
