USD selloff picks up steam

The heavy selling pressure surrounding the greenback on Tuesday seems to be fueling the pair's rally. In the absence of high-tier macroeconomic data releases, the risk-positive market environment is making it difficult for the dollar to find demand. The US Dollar Index was last seen losing 0.42% on the day at 93.55.

Later in the session, September Housing Starts and Building Permits data will be featured in the economic docket. In the meantime, the US stock index futures are up between 0.35% and 0.45%, suggesting that risk flows are likely to continue to dominate the financial markets in the second half of the day.
