Bloombergo is getting excited:
The typically risk-sensitive currencies were the top performers among a Group-of-10 peers last quarter, both climbing around 2% against the greenback despite a surge in volatility in global markets. Australia’s dollar closed 0.3% higher at 67.49 US cents on Friday, while New Zealand’s finished 0.5% stronger at 61.45 cents.
Rate hike bias from both the Reserve Bank of Australia and the Reserve Bank of New Zealand suggests the run may continue, offering protection from a strengthening greenback.
