Treasury yields rose early on Tuesday, ahead of the release of closely watched inflation data later in the morning.
BMO Global Asset Management's Steven Bell said on Tuesday that he expected the Fed to confirm plans to start tapering bond purchases at the end of the year.
He said this was now priced into markets, so expected attention to turn to when the Fed would start hiking interest rates, which depended on inflation and employment data?
"Figures out this week may show that inflation has cooled a bit in month-on-month terms but it remains well above the 2% target, it's employment that is holding the Fed back from pulling the trigger on a rate rise," Bell said.
