In Singapore, the US dollar remained stable on Tuesday after a challenging quarter, with investors anticipating reciprocal tariffs from President Donald Trump and the Australian dollar close to a four-week low before the central bank's policy decision. Traders are waiting for details on the new round of tariffs to be announced by the White House on Wednesday, causing uncertainty in currency markets. Trump has already imposed tariffs on various products, creating potential for market volatility and increased uncertainty for investors. The euro was steady at $1.082325, with a strong performance in the first quarter of the year, but doubts persist about its sustainability. The Japanese yen was slightly stronger at 149.66 per dollar, boosted by expectations of a Bank of Japan interest rate hike. Japanese business sentiment worsened in the first quarter due to escalating trade tensions, affecting the export-driven economy. The Reserve Bank of Australia's policy decision is set to impact Asian markets, with expectations for a steady cash rate but attention on the officials' tone. The RBA had cut rates in February but has been cautious about further easing measures. Australian economic data may lead the RBA to adopt a more dovish stance, given ongoing uncertainties.
