Both the dollar and Treasury yields are taking something of a breather after scaling multi-month peaks at the end of last month, powered by bets that an accelerating US recovery from the pandemic will lift inflation faster than Federal Reserve policymakers anticipate.
While the Fed's repeated insistence that near-term price pressures will prove transitory has soothed investors this month, the dollar firmed on Friday following stronger-than-expected producer price data, taking the edge off the currency's worst week this year.
The dollar index, which tracks the greenback against a basket of six rivals, was little changed at 92.304 in Asia, following a 0.9% slump last week. It dipped below 92 on Thursday for the first time since March 23.
The benchmark 10-year Treasury yield was at 1.6622% after dropping as low as 1.6170% last week. It had surged to a more than one-year high of 1.7760% on March 30.
"Key for the near-term outlook will be whether yields continue to consolidate around these levels, or march higher," which would support the dollar, National Australia Bank strategist Tapas Strickland wrote in a client note.

Fed Chair Jerome Powell speaks on Wednesday at the Economic Club of Washington.

Against the euro, the dollar hovered near the lowest since March 23 at $1.1901. It bought 109.66 yen, close to a two-week low below 109 reached on Thursday.
"USD has some upside potential this week," Commonwealth Bank of Australia strategist Kimberley Mundy wrote in a report.
"Strong US economic data will highlight the divergence between the US's fast economic recovery and the more stunted recoveries in other developed economies."
The dollar can lift back toward 110 yen, while the euro has scope to retrace most of that recent gains from its almost five-month low near $1.17, she said.
