NEW YORK (MarketWatch) -- Treasury prices added to gains on Tuesday, and the dollar declined against the euro after the Conference Board said its consumer confidence index fell to 48.5 in September. Yields on 10-year notes (UST10Y 2.49, -0.05, -1.82%) , which move inversely to prices, fell 6 basis points to 2.47%. The euro (EURUSD 1.3490, +0.0050, +0.3720%) rose to $1.3483, from around $1.3455 in late North American action Monday. The dollar index (DXY 79.34, -0.06, -0.07%) , a measure of the U.S. unit against a basket of six major currencies, traded at 79.382, paring earlier gains but up from 79.295 late Monday.
