S&P MARKETSCOPE: Treasuries extended losses from Friday. The July ISM manufacturing survey rose to 56.6 from 53.8 in June, outweighing an unexpected 0.3% decline in June construction spending.
The 10-year note fell 10/32 to 98-15/32 for a yield of 4.32%. The 30-year bond tumbled 21/32 to 113-20/32 for a yield of 4.51%.
Speculation of a strong July labor report Friday, following generally robust economic data lately, is expected to keep Treasuries in check this week.
