With few catalysts to drive business, investors are waiting to find out Yellen's views on the US economy when she sits before the Senate Banking Committee later Thursday.
She is unlikely to deviate from her comments to the House of Representatives' committee two weeks ago but investors will be interested to hear whether the bank expects the recent severe cold weather that paralysed parts of the country to have affected growth prospects.
A recent spate of downbeat data out of the United States over the past two months, including jobs growth, have been blamed on the cold snap.
Yellen's comments could give an idea of her plans for the Fed's stimulus programme, which has been reduced in each of the bank's past two policy meetings.
"Her comments on the current situation of the US economy, tapering (of its stimulus) and forward guidance (on interest rates) will be closely watched," Barclays currency analyst Shinichiro Kadota said in a note to clients.

In Sydney struggling Qantas slumped nine percent after it said it will axe 5,000 jobs, freeze pay, defer aircraft deliveries and suspend growth at Asian offshoot Jetstar while warning of more pain to come.
The airline, battling record fuel costs and fierce competition from subsidised rivals, posted an interim net loss of Aus$235 million (US$210 million) in the six months to December 31.
