Wall Street fell, while US Treasuries rose, after minutes from the July Federal Reserve meeting suggested US policy makers might not raise interest rates next month.
"Most [participants] judged that the conditions for policy firming had not yet been achieved, but they noted that conditions were approaching that point," according to minutes from the Federal Open Market Committee's July 28-29 meeting, released on Wednesday.
"Participants observed that the labour market had improved notably since early this year, but many saw scope for some further improvement," the minutes showed.
To be sure, "it was also noted that a prompt start to normalisation would likely convey the Committee's confidence in prospects for the economy," according to the minutes.
Most analysts interpreted the Fed's comments as suggesting a September rate hike may be off the table.
"The Fed is backing off from September," John Herrmann, director of US rate strategy at Mitsubishi UFJ Securities USA, told Bloomberg. "They are still saying they have not seen enough."
