Economic Growth Forecasts: Stronger economic growth typically leads to a steeper yield curve, while weaker growth can flatten or even invert it.

Federal Reserve Policy: Actions taken by the Federal Reserve, such as quantitative easing or tightening, directly affect interest rates and the shape of the yield curve.

Global Economic Conditions: International economic events and policies can indirectly influence the 2Y10.F spread by affecting capital flows and risk sentiment.

Market Sentiment: Overall investor confidence or fear can impact demand for different maturities of bonds, altering the spread.

Supply and Demand: The supply of Treasury bonds at different maturities, relative to investor demand, affects yields and the 2Y10.F spread.

Risk Aversion: Increased risk aversion typically flattens the yield curve as investors flock to safe-haven assets like long-term Treasury bonds.
