NEW YORK - The dollar fell to three-week lows on Friday as optimism that a deal for new U.S. stimulus would be reached, and as investors bet that Democrat Joe Biden is more likely to win the U.S. presidency and offer a larger economic package.

After stalling talks with Democrats on a comprehensive aid package earlier this week, U.S. President Donald Trump on Thursday called for a "skinny" relief bill that would include elements such as direct payments and a bailout of the struggling airline sector. 

Senate Majority Leader Mitch McConnell said another rescue package was needed but noted "vast differences" over costs. U.S. House of Representatives Speaker Nancy Pelosi said legislation to help airline companies could only move through Congress with guarantees that a comprehensive aid bill would be developed too. 

“It seems like, at least in the White House, there is more of a sense of urgency that it needs to be done,” said Bipan Rai, North American head of FX strategy at CIBC Capital Markets in Toronto. However, “the key question for us is whether or not the Senate Republicans are going to go with it … they don’t seem to be united.”

“I think we’re more or less in a standstill until we get some more clarity on whether or not this stimulus package is going to go through,” Rai said.

The dollar index against a basket of major currencies fell 0.34% to 93.23, the lowest since September 21. It has held within a range from 91.74 to 94.75 since late July.

The euro rose 0.45% to $1.1811. The greenback weakened 0.16% against the Japanese yen to 105.84 yen.

The U.S. currency also fell on rising expectations that Biden will win the Nov. 3 election, and that Democrats could win the Senate. A Democratic victory would likely result in larger stimulus, which would be negative for the dollar.

Rising expectations of a Biden victory has also boosted appetite for currencies that have been hurt by the trade war between Washington and Beijing, with the Chinese currency the biggest beneficiary.

The offshore yuan strengthened to 6.6801, the strongest since April 2019.

The pound was steady, brushing off worse than expected UK growth data as investors became more optimistic about a Brexit deal being reached ahead of a key European Council summit next week.

Sterling was last up 0.29% at $1.2970.
