May 31, 2021 15:21 GMTFXStreet News AUD/USD is trading in the positive territory on Monday. US Dollar Index fluctuates in a very tight range at the start of the week. Focus shifts to Reserve Bank of Australia’s (RBA) policy announcements. The AUD/USD pair registered small losses last week but managed to stage a rebound on Monday. As of writing, the pair was rising 0.32% on a daily basis at 0.7738. Nevertheless, with the trading conditions remaining thin due to the Memorial Day holiday in the US, AUD/USD is likely to spend the rest of the day in a tight range. Reflecting the choppy market action, the US Dollar Index is moving sideways around 90.00.
