DXY closes in on 94.00

The US Dollar Index (DXY), which gained 1.7% last week, staged a technical correction on Monday and closed in the negative territory. Ahead of key macroeconomic data releases and the first presidential debate, the DXY pushed lower on Tuesday and helped AUD/USD preserve its bullish momentum. At the moment, the DXY is down 0.25% at 94.04.

The US Census Bureau will release the Goods Trade Balance data for August at 1230 GMT. Later in the session, the Conference Board's Consumer Confidence Index data will be looked upon for fresh catalysts.

Meanwhile, the S&P 500 futures are down 0.15% on the day, suggesting that Wall Street could start the day modestly lower. Investors are likely to adopt a cautious mood in the second half of the day and the USD could take advantage of the risk-averse market environment and start recovering its losses against its major rivals.

On Wednesday, Building Permits and Private Sector Credit data will be featured in the Australian economic docket.
