1620 ET - Treasury yields fall ahead of September's U.S. jobs report, which is expected to bolster the case for a slower pace of monetary tightening. Economists surveyed by WSJ forecast job creation slowing to 84,000 from 162,000. The Treasury buys back $6 billion in long-term bonds, exceeding previous operations' amounts. A flight for safety boosts demand for German bunds and U.S. Treasurys, weakening yields, as investors ditch debt from highly indebted European governments. Borrowing costs, however, remain close to multidecade highs. The 10-year Treasury yield slips 0.059 percentage point, snapping a seven-day rising streak, to 5.233%. The two-year drops 0.1 point to 4.785%.
