NEW YORK (MarketWatch) -- Treasury prices came under a bit more pressure and the dollar pared losses against a basket of major currencies on Tuesday after the Conference Board said its index of consumer confidence unexpectedly fell to 52.5 this month. Gold futures slipped from the highs of the day after the data but held onto the bulk of gains. The dollar index (DXY 80.20, -0.16, -0.20%) , which measures the greenback against a basket of six major currencies, fell to 80.229, down from 80.34 in North American trading Monday. Yields on 10-year notes (UST10Y 3.38, +0.05, +1.47%) , which move inversely to prices, rose 5 basis points to 3.39%. Gold for February delivery (GCG11 1,401, +18.10, +1.31%) gained $18.40 to $1,401.30 an ounce.
