Yield Curve Explorer: Term Structure of Interest Rates

The yield curve — the relationship between a bond's maturity and its interest rate — is one of the most closely watched signals in finance. This simulator builds the curve from the Nelson-Siegel model used by real central banks, letting you drag the level, slope, curvature and decay parameters and watch the term structure reshape in 3D across ten standard maturities from 3 months to 30 years. A fading trail of recent curve shapes recedes into the distance, forming a live surface that shows how the curve moves through time, while the 2s10s spread, an implied 1Y1Y forward rate, and short/long yields update live — with the curve and its readouts turning red the moment the classic recession signal, a negative 2s10s spread, appears.
