Treasury yields fell on Wednesday after the U.S. midterm elections resulted in the Democrats winning the House of Representatives and the Republicans retaining the Senate.
Bond traders said that the as-expected results are not likely to see major reactions from credit markets, though some said a split Congress could stall plans for further tax cuts or major spending. That, in turn, could be a modest boon for bonds prices, which have come under pressure thanks to historic deficit spending and debt issuance from the Treasury Department.
As of 1:58 p.m. ET, the yield on the benchmark 10-year Treasury note fell to around 3.199 percent, while the yield on the 30-year bond dropped to 3.403 percent. Meanwhile, the yield on the two-year note rose to around 2.944 percent. On Tuesday, the two-year yield hit its highest level since 2008. Bond yields move inversely to prices.
"We think a gridlock environment for an economy poised to decelerate makes it harder now for the full term structure to keep rising," George Goncalves, head of fixed-income strategy at Nomura Securities International, said in an emailed statement.
"In the short run, this does not change the trajectory of the Fed, so curves should flatten," Goncalves added. "In the more medium term, we still believe that 10-year rates can make another move above 3.25 percent, but our conviction is lower now."
The Federal Reserve's policymaking arm gathered on Wednesday for the first session of a two-day meeting. Concerns around the pace of interest rate hikes led to a roller-coaster ride for global markets last month. Markets have been pricing in a higher probability that the Fed raises rates again in December, with further tightening seen through 2019.
Fed officials, responsible for keeping unemployment low and inflation tame, have gradually increased interest rates under Chair Jerome Powell as they try to prevent the U.S. economy from overheating.
The Federal Open Market Committee will announce its latest adjustment to monetary policy on Thursday. Should the central bank choose to tweak its policy in November, it's likely it will move to increase the rate paid by the Fed for excess reserves. No major adjustments are expected from the November meeting, however.
The Treasury Department auctioned $19 billion in 30-year bond at a high yield of 3.418 percent. The bid-to-cover ratio, an indicator of demand, was 2.06. Indirect bidders, which include major central banks, were awarded 59.1 percent. Direct bidders, which includes domestic money managers, bought 2.9 percent.
