NEW YORK (MarketWatch) -- Treasury prices improved, but longer-dated debt remained in negative territory, pushing yields up, after a pair of reports showed consumer prices rose 0.3% last month, more than economists expected, while the pace of housing starts fell short of forecasts. Yields on 10-year notes (UST10Y 3.32, -0.01, -0.21%) rose 2 basis points to 3.35%.
