US Dollar struggles near two-week lows, around 93.00 handle

   •  US tax bill optimism/surging US bond yields fail to provide any lift.
   •  This week’s key event/macro data eyed for fresh directional impetus.

The US Dollar Index, which measures the greenback's performance against a basket of six major currencies, languished near two-week lows during the Asian session on Wednesday. 

Downside remained cushioned on firming expectations for a much-awaited tax package after the House of Representatives passed the closely watched tax-cut legislation, though has been delayed due to some procedural hiccups. 

The House Republicans will need to pass the biggest US tax overhaul in 30 years for a second time later on Wednesday, with expectations of additional US bond issuance driving the US Treasury bond yields higher and lending some support to the buck.

Despite supporting factors, the greenback has failed to gain any positive traction as investors now look forward to important US macro data for fresh directional impetus. This week's US economic docket features the final US GDP growth figures for the third-quarter and the key durable goods orders, which along with the BoJ monetary policy announcement might infuse some volatility ahead of the year-end holiday season.
