The two-year US Treasury note yield, which typically moves in step with interest rate expectations, fell on the day, and was down at 3.9531% early on Friday, keeping the dollar under pressure.
The dollar index, which measures the currency against six peers, was flat at 102.84 as of 0111 GMT, but down 0.3% from 103.17 on Thursday, which was its highest level since Aug 15. For the week, the index is on track for 0.39% advance, building on the previous week's 2.06% surge.
While the Fed has signalled a shift in its focus towards full employment over price stability, investors had been looking to the CPI print for confirmation that inflation was coming under control.
"The net impact was some volatility in global markets, but on net, yields are not greatly changed," said Tapas Strickland, head of market economics at National Australia Bank.
"Overall, the (CPI result) doesn't change the story of moderating inflation narrative, and should keep the Fed on getting policy back to a more neutral setting, wherever that may be."
Comments from Fed officials on Thursday pointed to a divide in views, with Chicago Fed President Austan Goolsbee saying the "vast majority" of Fed policy makers expect rates will "gradually come down a fair amount to something well below where they are today", while Atlanta Fed President Raphael Bostic said he is "definitely open to" skipping a rate cut in November.
The dollar added 0.06% to 148.68 yen, inching back towards Thursday's high of 149.58 yen, a level previously not seen since Aug. 2.
The euro was steady at $1.093650 after bouncing back overnight from a two-month low at $1.090025.
The Australian dollar held firm at $0.67395 after rebounding from its lowest since Sept. 16 at $0.6702 on Thursday.
