Chicago Fed National Financial Conditions Index (NFCI)

What it is: A weekly composite of 105 financial-market indicators across money markets, debt markets, equity markets, and the banking system. Constructed so zero equals average historical financial conditions; positive readings indicate tighter than average and negative readings indicate looser.

Why it matters: Financial conditions sit one step removed from the real economy — they reflect the cost and availability of credit, which then propagates to investment, hiring, and consumption with a lag. The NFCI is the single most-watched composite measure because it aggregates dozens of indicators that any one chart would miss.

How to read it: Above zero is tight, below zero is loose — opposite to the intuitive direction. Sustained readings above +1 are historically associated with credit-market stress and recession risk; sustained readings below −0.5 indicate unusually loose conditions and excess risk-taking, which often precedes the tightening cycles that follow. The level matters more than short-term wiggles.

NFCI Long View

What it is: The same NFCI series shown above, displayed from 1971 to present.

Why it matters: The long view shows the four major financial-conditions tightening episodes of the modern era — the early-1980s Volcker disinflation, the 1990 banking crisis, the 2008 financial crisis, and the brief 2020 COVID shock. Each tightening corresponds to a different cause but produced similar real-economy outcomes.

How to read it: Use this chart to calibrate current readings against history. The Volcker-era peak above +4 is the upper bound of what tight financial conditions have ever looked like; the post-2009 trough below −1 is the lower bound. Readings within ±0.5 are the normal-conditions band. Recent readings should be evaluated against this full range, not just the post-2008 era.

Corporate Credit Spreads — High Yield, BBB, Investment Grade

What it is: Option-adjusted spreads on US corporate bond indices over comparable Treasuries — for High Yield (junk-rated), BBB (the marginal investment-grade tier), and the broad Investment Grade universe. Reported daily as a percent above the risk-free benchmark.

Why it matters: Spreads are the bond market's direct pricing of corporate credit risk — what investors require above the risk-free rate to lend to companies. Unlike the NFCI, which is a constructed composite, these are real prices traded continuously by professional investors. When spreads compress, the market is signaling complacency about default risk; when spreads widen, the market is repricing for trouble.

How to read it: All three spreads move together in normal times — they fan apart in stress. The shape of the fan matters: when HY widens dramatically while IG stays compressed, the market is pricing differentiation between strong and weak credit. When all three widen together, the market is pricing a systemic event. Compressed spreads (HY below 3%, IG below 1%) historically reflect underpriced risk that gets repriced sharply higher in subsequent credit-stress events.

Moody's Baa Corporate Spread Over 10-Year Treasury, Long View

What it is: The yield on Moody's Baa-rated corporate bond index minus the 10-year US Treasury constant-maturity yield, shown from 1986 to present. Baa is the lowest tier of investment-grade credit — the marginal IG borrower.

Why it matters: The ICE BofA spreads shown above provide cross-sectional detail on current credit conditions but only have three years of history. The Moody's Baa-Treasury spread is a long continuous credit-quality spread series, going back four decades. It captures the same fundamental dynamic — what investors require to hold corporate credit over the risk-free benchmark — across multiple monetary regimes, regulatory eras, and credit cycles.

How to read it: Spreads peak during credit-stress events: the early-1980s Volcker disinflation, the 1990 banking and S&L crisis, the 2002 telecom bust, the 2008 financial crisis, the 2011 European sovereign crisis, the 2020 COVID shock, and the 2022 rate shock. Each peak corresponds to a different cause but the pattern is consistent — spreads compress to near 1% in late-cycle complacency, then widen sharply when the cycle turns. The long history makes the rhythm visible. Compare current readings against this rhythm rather than against the post-2008 era alone.

Federal Reserve Total Assets

What it is: The total assets on the Federal Reserve's balance sheet, reported weekly in trillions of dollars. Includes Treasury securities, mortgage-backed securities, repo operations, and emergency lending facilities.

Why it matters: The Fed's balance sheet is the most direct measure of the central bank's monetary footprint in the financial system. When the Fed buys assets (QE), it creates new bank reserves; when it lets assets run off (QT), it destroys them. Changes in the balance sheet translate to changes in the quantity of base money supporting the economy.

How to read it: The pre-2008 baseline was roughly $900 billion. Three discrete expansions followed: QE1–QE3 from 2008 to 2014 (to ~$4.5 trillion), the COVID expansion from March 2020 to early 2022 (to ~$9 trillion), and the post-2022 QT contraction. The level shows the cumulative monetary footprint left behind by each cycle. Each expansion was advertised as temporary; each ended with the balance sheet meaningfully larger than where it started.

Federal Reserve Total Assets, YoY %

What it is: The year-over-year percent change in the Fed's total assets — the flow rate at which the balance sheet is expanding or contracting.

Why it matters: While the level shows cumulative monetary footprint, the YoY change shows whether the Fed is currently adding or removing liquidity. Real-time monetary impulse runs through this flow, not the static level.

How to read it: Above zero means the balance sheet is expanding (net liquidity injection); below zero means contracting. Major expansions (above 30% YoY) coincide with crisis interventions — visible spikes in 2008–2009 and 2020. Sustained negative YoY readings are the QT periods, historically rare and shorter than the expansions that preceded them. The asymmetry between fast expansions and slow contractions is the central feature of post-2008 monetary policy.
