Investing.com - The Australian and New Zealand dollars moved lower against their U.S. counterpart on Monday, as fresh expectations for an upcoming U.S. rate hike continued to support demand for the greenback.
AUD/USD slid 0.45% to 0.7594, the lowest since August 4.
The greenback remained supported after San Francisco Federal Reserve Bank President John Williams on Thursday signaled support for a September rate increase.
"In the context of a strong domestic economy with good momentum, it makes sense to get back to a pace of gradual rate increases, preferably sooner rather than later," he said.
Minutes of the Federal Reserve's July policy meeting published earlier in the week showed committee members remained divided on the timing of the next rate hike, although there is general agreement that more data is needed before such a move.
NZD/USD declined 0.65% to trade at 0.7226, the lowest since August 17.
The U.S. dollar index, which measures the greenback’s strength against a trade-weighted basket of six major currencies, was up 0.39% at 94.86, the highest since August 17.
