Yields for 10-Year Treasury Notes moved lower to start the week, with the 10-Year yield closing back below 4.00% for the second time in three sessions, a level seen only once in the previous year. This volatility in the market is being driven by lingering uncertainties regarding the U.S. government shutdown and how the Federal Reserve will respond at the upcoming Federal Open Market Committee meeting without all the regular economic data. Concurrently, volatility has been in decline since peaking approximately a week and a half ago. Looking ahead, traders will receive the privately released Philly Fed Non-Manufacturing index and the market is also expecting a delayed release of Friday's Consumer Price Index, which may offer the Federal Reserve some clarity before the October FOMC meeting.
