SAN FRANCISCO (MarketWatch) -- U.S. Treasurys Tuesday added to gains, sending yields lower, after the Conference Board's reading on consumer confidence data showed a dip in March. Yields on the 10-year Treasury note 10_YEAR -0.89% were down 4 basis points at 2.2% versus a 2 basis-point drop ahead of the 10 a.m. Eastern data. Yields on the 7-year note 7_YEAR -1.58% were off 5 basis points at 1.59%. What's known as the "belly" of the yield curve, or mid-range maturities such 7-year notes, are rallying the most on Tuesday following Federal Reserve Chairman Ben Bernanke's comments on interest-rate policy Monday.
