In macroeconomic and monetary policy discussions, NFCI stands for the National Financial Conditions Index. Published weekly by the Federal Reserve Bank of Chicago, it delivers a comprehensive weekly assessment of U.S. financial health by tracking over one hundred individual indicators spanning money markets, debt and equity securities, and traditional or shadow banking systems. The index breaks down financial pressures into risk, credit, and leverage sub-components, enabling economists and market participants to evaluate whether overall financial conditions are tighter or looser than historical norms.
