The yield on the US 10-year Treasury note fell below 4.22% on Monday, the lowest level in nearly two weeks, as worries mount of another government shutdown after Democratic leaders threatened to block approval of a $1.2 trillion funding package if it includes additional allocations for Homeland Security, following another shooting involving a US citizen in Minnesota. Investors are also awaiting the Fed’s first monetary policy decision of the year on Wednesday. While a hold is widely expected, traders will focus closely on the Fed’s economic outlook and commentary on future rate policy. There is also speculation that the next Fed chair could be announced as soon as this week.
