Rates moved lower Tuesday in quiet trading ahead of this week’s Fed meeting, Treasury auctions, and key economic data. Consumer Confidence rose for the third straight month in January according to the Conference Board. The reading came in at 55.9, beating expectations. The rest of the week may prove volatile for mortgage-backed securities with tomorrow’s FOMC meeting, Friday’s preliminary fourth quarter Gross Domestic Product figures, and large Treasury auctions of 2-, 5-, and 7-year notes beginning this afternoon. No other data will be released today.
