1604 ET - Bond markets seem to indicate increasing concerns about U.S. long-term fiscal stability, as the yield curve steepens. Signs of cooling inflation and growth bolster odds of another Fed hold in September, weighing on shorter-term yields, while long-term yields rise on fiscal concerns. The Treasury pays the highest yield since 2001 in this week's 30-year auction. Fed minutes are due Wednesday. The 10-year yield rises 0.038 percentage point this week, to 4.695%, while the two-year declines 0.032 p.p., to 4.170%.
