The dollar index gained 0.4% to 96.60, trimming its weekly decline to 0.9%

The dollar rose ‌on Friday, paring its weekly slide, after U.S. President Donald Trump said he would soon announce his nominee to head the U.S. central bank and on optimism Washington will avert a government shutdown.

Trump said he intends to name his pick to replace central bank Chair Jerome Powell ⁠on Friday, following reports that former central bank Governor Kevin Warsh visited the White House.

The appointment of Warsh, if it’s true, will be ​seen as someone who can, in a way, remain independent, and not someone seen as likely to be subservient to Trump’s wishes, said Khoon Goh, head of Asia research ‍for ANZ in Singapore. Any sensible market participant would not want to carry a big position into the weekend, he added. So, some of this could just be positioning lightening up. If you’re short dollars, you’ve done well, take your chips off the table.

The dollar index gained 0.4% to 96.60, trimming its weekly decline to 0.9%. Against the Swiss franc, the dollar firmed 0.7% to 0.7699. The euro dipped ⁠0.4% at $1.1916, ‌while the yen weakened 0.42% to 153.77 per dollar. ⁠Sterling weakened 0.32% to $1.3759.

Meanwhile, the White House said that Trump signed an executive order that would impose tariffs on countries that provide oil to Cuba. Reports that the country’s president is considering strikes ​against Iran prompted a surge in oil prices and weighed on the dollar earlier. The U.S. domestic front got a glimmer of hope after Trump endorsed a spending deal ⁠negotiated by U.S. Senate Republicans and Democrats that would stave off a government shutdown.
