Today's 20-year Treasury re-opening is the largest market test within the fixed-income segment. Given that long-term yields are already elevated, demand at this auction will significantly impact the market: weak demand could push yields higher and pressure equities, while strong demand could lower yields and support equities. Additionally, the Federal Reserve's Federal Open Market Committee (FOMC) begins its two-day meeting today, though there are no major Federal Reserve official speeches scheduled for today; the interest rate decision, dot plot, and Jerome Powell's press conference will take place on Wednesday. The market will also be watching the Empire State Manufacturing Survey data and the API crude oil inventory report.
