The dollar edged higher against a basket of major currencies on Wednesday, on optimism about progress on U.S. tax legislation and lawmakers' efforts to avert a U.S. government shutdown on Saturday.

The dollar index, which measures the greenback against six rival currencies, was up 0.25 percent at 93.61.

Republicans in the U.S. House of Representatives began staking out their positions on final tax legislation on Tuesday, days ahead of talks with the Senate to shape the tax package.

The yen tends to benefit during geopolitical or financial stress as Japan is the worlds biggest creditor nation and there is an assumption that Japanese investors will repatriate funds should a crisis materialize.

"It's a safe-haven play," Harajli said.
