Australian Dollar Dips Amid RBA Rate Decision and Geopolitical Tensions

The Australian dollar weakened on Tuesday as the Reserve Bank of Australia (RBA) raised interest rates by 25 basis points to 4.1% amid rising inflation concerns. Despite the rate hike, the unexpected close vote led traders to scale back expectations of further tightening, causing the Aussie to slide 0.25% to $0.7053.

With five board members supporting the rate increase and four opposing, the decision was the RBA's tightest since it began revealing vote tallies. The central bank noted a 'material risk' of prolonged inflation above targets, citing uncertainties in the Middle East as potential contributors to global and domestic inflation pressures.

Investor sentiment turned jittery as tensions surrounding the U.S.-Iran conflict led to surging oil prices, triggering a sharp repricing of global rates. The U.S. dollar, benefiting from its safe-haven status, gained against most currencies, while the yen weakened ahead of the Bank of Japan's policy meeting.
