NEW YORKNEW YORK (Reuters) - The dollar dipped on Tuesday and riskier currencies including the Australian dollar gained as U.S. stocks were stable, reflecting improving risk appetite.
The greenback has been a beneficiary from recent volatility in stocks, which were roiled last week by a dramatic jump in U.S. government debt yields.
Treasuries have stabilized this week, with benchmark yields holding below last week's highs, helping to restore some market calm.
On Tuesday, "Wall Street largely retained Monday's sharp gains," which helped the U.S. currency "ease lower through the N.Y. session," Ronald Simpson, managing director, global currency analysis at Action Economics, said in a report.
The dollar index fell 0.31% to 90.731, after earlier reaching a three-week high of 91.396.
The euro gained 0.36% to $1.2092.
Rising yields came as participants worried that an economic recovery from the impact of the COVID-19 pandemic, combined with fiscal stimulus, will cause a jump in inflation and potentially faster tightening from the Federal Reserve.
The volatility also boosted the greenback as investors unwound short positions in the currency.
“If you do see volatility, the natural inclination is to take risk off the table; in this case it just basically means getting out of existing positions, and the dollar shorts are extremely elevated at this point” said Bipan Rai, North American head of FX strategy at CIBC Capital Markets in Toronto.
Short U.S. dollar positions were $29.33 billion in the week ended Feb. 23, according to data from the Commodity Futures Trading Commission.
Riskier currencies including the Australian dollar continued to rebound from last week’s sell-off, with the Aussie also gaining after the Reserve Bank of Australia recommitted to keeping interest rates at historic lows.
The currency was last up 0.77% at $0.7831, though it remains below the three-year high of $0.8007 reached on Thursday.
Karen Jones, a technical analyst at Commerzbank, said that the Aussie and other risky currencies including the Norwegian krone appeared to be reversing from interim tops, which will likely be positive for the U.S. dollar near-term.
The “U.S. dollar bear trend is probably over” for now, Jones said in a report.
The greenback was last down 1.09% at 8.466 krone, but is holding above the 8.313 krone per dollar level reached last week, the weakest for the dollar in more than two years.
Safe-haven currencies including the Swiss franc and Japanese yen, meanwhile, ended slightly stronger, reversing earlier weakness.
The Swiss franc earlier hit its lowest since November 2020 against the dollar at 0.9193 while the yen was the weakest since August at 106.95.
Bitcoin fell to a session low after Gary Gensler, President Joe Biden's nominee to chair the U.S. Securities and Exchange Commission, said that cryptocurrency has raised new investor protection concerns.
It was last down 4.11% at $47,609.
Citi said in a report that the popular cryptocurrency was at a "tipping point" and could become the preferred currency for international trade or face a "speculative implosion."
