#AirdropSafetyGuide The dollar drifted higher on Friday, following small losses a day earlier, as traders grappled with the outlook for the U.S. economy following President Donald Trump's erratic messaging on trade deals and Federal Reserve interference.The U.S. currency has oscillated wildly this week, starting with a 1% tumble against major peers on Monday after Trump threatened to fire Fed Chair Jerome Powell for not cutting interest rates quickly enough, only to surge 1.5% a day later as Trump said he never had any intention of replacing Powell, and mooted a de-escalation in his trade war with China.A lack of actual progress towards opening talks with Beijing, though, had the dollar drooping again later in the week. For the week overall, the dollar index - which measures the currency against six major peers - is on course for just a 0.27% rise, although that would still snap a four-week losing run.Investors are particularly in the dark about where things currently stand with China. Beijing asserted on Thursday that it has not held trade talks with Washington, although Trump repeated later in the day that direct negotiations are underway.Early on Friday, the dollar was up 0.3% at 143.08 yen, and 4% stronger at 0.8303 Swiss franc.
