The U.S. central bank is widely anticipated to raise interest rates Wednesday. Market expectations for a June rate hike were at 95.8 percent Monday, according to the CME Group's FedWatch tool.
Fed officials should also give a nod to the fact that inflation is weaker but that they remain confident about the economy. Fed Chair Janet Yellen is also expected to talk more about how the Fed could move ahead to pare back its massive $4.5 trillion balance sheet later this year.
Monday also saw a $24 billion three-year note sale at a high yield of 1.5 percent. The bid-to-cover ratio, an indicator of demand, was 3.
Indirect bidders were awarded 65.6 percent, while direct bidders bought 6.2 percent.
The department also auctioned $20 billion in 10-year notes at a high yield of 2.195 percent on Monday. The bid-to-cover ratio, an indicator of demand, was 2.54.
