Credit Spreads Tracker: HYG/LQD Ratio, Credit Stress & Risk-Off Signal

Free credit-spreads tracker. The HYG / LQD ratio with rolling 1-year and 3-year z-scores classifies the credit market as Risk On, Neutral, or Risk Off. When high-yield bonds underperform investment grade, credit can signal stress ahead of equities — a widely watched early-warning indicator. 15 years of daily history (2011–present): the primary HY/IG ratio, regime classification, per-ETF returns across the credit complex, four supporting ratios, and the CFTC's weekly transaction and outstanding-notional read on the credit-swaps market.

Underlying ETFs: HYG (iShares iBoxx $ High Yield Corporate Bond), LQD (iShares iBoxx $ Investment Grade Corporate Bond), and seven peers across the credit and Treasury complex. Pair this read with the VIX term structure, Hindenburg Omen, and sector health for cross-asset confirmation.

Today's reading

As of market close on July 22, 2026, the HYG/LQD credit ratio is 0.7455 — +2.65σ vs its 1-year history and +1.85σ vs its 3-year history. That puts the spread regime at TIGHT (day 12), a risk-on credit read. The ratio rose from 0.7454 the prior session. The series covers 3,869 trading days since 2011. The latest CFTC report, covering the week ended July 3, 2026, recorded $447.7 billion of market-facing credit-swap notional — the 23rd percentile of its trailing year, classified QUIET. That is an activity measure, not a directional CDS-spread signal.

CFTC credit-swaps activity — weekly

Actual swaps-market data

Credit-swap turnover is quiet — a volume read, not a direction call

In the week ended July 3, 2026, the CFTC recorded $447.7B of new market-facing credit-swap notional — 17.9% below its prior four-report average and the 23rd percentile of the trailing year. Index and tranche products accounted for $258.8B across 4,408 tickets.

This answers a different question from HYG/LQD: how much credit risk changed hands, not whether protection became more expensive. High volume can reflect hedging, unwinds, rolls, or rebalancing, so an activity surge is not automatically bearish.

S&P 500 vs credit spreads

Range:

Credit risk premium vs the S&P 500 — since 1993

The HYG/LQD ratio only reaches back to 2011. For the long view, the credit risk premium — Moody's Baa corporate yield minus the 10-year Treasury, a 3-year moving average on an inverted axis so tight spreads sit at the top — is plotted against the S&P 500 (grey, right axis). Credit has compressed to cycle lows before prior equity tops; the dashed line marks today's level.

Credit line: Moody's Baa corporate yield − 10Y Treasury (FRED BAA10Y), 3-year MA, inverted axis. S&P 500 via SPY on a log scale. We use Baa−10Y because FRED now serves the ICE BofA high-yield OAS (BAMLH0A0HYM2) only from 2023 — today's HY OAS is 2.69%. Tight spreads flag late-cycle complacency, not timing: they stayed tight for years into 1998–2000 and 2005–07.

Three ways to watch credit spreads

The metric on this page is an ETF price ratio: HYG (iShares iBoxx $ High Yield Corporate Bond ETF) divided by LQD (iShares iBoxx $ Investment Grade Corporate Bond ETF). It's a tradeable, freely available proxy for credit-market risk appetite — but it is not the same thing as a traditional credit spread, and a professional desk would typically watch all three of the views below in parallel.

Traditional credit spreads — like the ICE BofA US High Yield Index Option-Adjusted Spread (OAS) published by FRED as BAMLH0A0HYM2 — measure the actual yield differential between high-yield bonds and comparable Treasuries, controlled for embedded options. Bloomberg and Refinitiv terminals additionally provide intraday bond-level pricing and curve analytics that neither this page nor FRED can match.

For most discretionary purposes, the ETF ratio is sufficient and timelier than FRED OAS. For research that requires literal spread levels (basis points over Treasuries) or that needs to reproduce academic studies, prefer the FRED OAS series. For real-time execution on individual issuers, a terminal is the right tool.

Historical event study — did credit see it coming?

How well credit spreads have signaled equity drawdowns over the past two decades. The signal has worked clearly in some episodes (2007–2008, sector-level in 2015–16) and barely registered in others (2020 was coincident, 2024 was cross-asset volatility). Use this as context for any single read — credit is one input among several, not a standalone forecast.

EventWindowHY OAS beforeHY OAS peakSPY drawdownLead/lag read
2007–2009 Global Financial CrisisJul 2007 – Mar 2009~3% in mid-2007~21.8% (Nov 2008)–55% peak-to-troughCredit led — HY OAS started widening months before the equity peak in October 2007.
2011 European Debt CrisisJul – Oct 2011~5% in mid-2011~9% (Oct 2011)–19% peak-to-troughRoughly coincident — credit and equities widened/sold off together over a few weeks.
2015–2016 Energy / EM StressJul 2015 – Feb 2016~5% in mid-2015~9% (Feb 2016)–14% peak-to-troughCredit-led at the sector level — energy HY blew out well before broad equity weakness.
Q4 2018 selloffSep – Dec 2018~3.2% in Sep 2018~5.4% (Dec 2018)–19% peak-to-troughRoughly coincident — modest credit signal relative to the depth of the equity drawdown.
2020 COVID crashFeb – Mar 2020~3.5% in Feb 2020~11% (late Mar 2020)–34% in 33 daysLargely coincident — both moved violently in the same weeks. Credit didn't provide much lead time.
2022 rate-hike cycleJan – Oct 2022~3% in Jan 2022~6% (Sep 2022)–25% peak-to-troughModest credit signal vs depth of equity drawdown — this was primarily a duration / discount-rate event.
Aug 2024 yen carry unwindAug 2024~3% beforehand~3.5% (no notable spike)–8% (brief)Credit barely moved — this was a cross-asset volatility/leverage event, not a credit event.

Approximate peak HY OAS values from the ICE BofA US High Yield Index Option-Adjusted Spread (FRED: BAMLH0A0HYM2). Figures are rounded for readability — consult FRED for exact values. SPY drawdowns measured peak-to-trough on SPY price.

Takeaway: credit-spread widening has been a useful but inconsistent leading indicator. It worked best in episodes where the underlying stress was credit-driven (2007–08, sector-level energy in 2015–16). It worked poorly when the equity drawdown was driven by something else — discount-rate shocks (2022) or pure volatility/leverage events (2020, 2024). Pair this with VIX, breadth, and price action.

How Credit Spreads Tracker Works

  1. 1
    Pull daily prices for nine credit and Treasury ETFs
    Each trading day after the close, we fetch closing prices for HYG, JNK, LQD, EMB, BKLN, AGG, TLT, IEF, and SHY directly from the TradeStation market-data API.
  2. 2
    Compute the HYG/LQD ratio plus three supporting ratios with rolling z-scores
    The primary signal is HYG (high-yield corporates) divided by LQD (investment-grade corporates). We z-score it against rolling 252-day (1-year) and 756-day (3-year) windows. Three supporting ratios — JNK/AGG, EMB/LQD, and TLT/HYG — give cross-confirmation.
  3. 3
    Classify the current regime and surface as Risk On or Risk Off
    Z-scores ≥ +1σ are TIGHT (Risk On). Between -1σ and +1σ is NORMAL (Neutral). -1σ to -2σ is WIDE (Risk Off). Below -2σ is STRESS (severe Risk Off). The big label at the top of the page tells you which regime credit is currently in.
  4. 4
    Add the CFTC’s weekly credit-swaps activity report
    Each Monday release adds market-facing credit-swap transaction notional, ticket counts, index/tranche share, clearing share, and gross outstanding notional aggregated across registered swap data repositories. We use only the comparable post-December-2022 methodology. This measures how much risk changed hands, not whether CDS protection became more expensive.
  5. 5
    Zoom out 30 years: the S&P 500 vs the credit risk premium
    The HYG/LQD ETF ratio only goes back to 2011. For the long view, a second chart overlays the S&P 500 (log scale) on the credit risk premium — Moody's Baa corporate yield minus the 10-year Treasury (FRED BAA10Y, daily since 1986) — inverted and smoothed with a 3-year moving average, so tight spreads sit high and align with equity peaks. It uses Baa-10Y because FRED now serves the ICE BofA high-yield OAS only from 2023; the current HY OAS is shown alongside. Credit has historically compressed to cycle lows (late-1990s, 2006-07) before equity tops — though tight spreads flag complacency, not timing.
  6. 6
    Watch the weakest credit: CCC junk spreads vs the S&P 500
    A third chart plots the lowest-quality junk tier — the ICE BofA CCC & Lower high-yield OAS (FRED BAMLH0A3HYC), weekly on an inverted axis — against the S&P 500. CCC borrowers are the most fragile, so their spreads widen first when credit conditions deteriorate; CCC widening while equities hold near highs is the classic late-cycle warning. FRED licensing limits this series to 2023+, so it is a recent rather than multi-decade view.

Who Uses Credit Spreads Tracker

Day Traders
Use credit spreads as a same-session confirmation or contradiction of equity moves. When SPY breaks higher but HYG/LQD diverges lower, the rally is suspect.
Swing Traders
Identify regime shifts that may precede equity moves. Credit markets often react to early signs of stress before equity markets, giving swing positions time to adjust.
Long-Term Investors
Monitor systemic credit health as part of a broader risk dashboard. Sustained credit-stress regimes have historically coincided with or preceded major equity drawdowns.
Risk Managers
Cross-asset risk dashboard input. Combine the HYG/LQD z-score with VIX, breadth, and yield-curve signals to build a multi-factor risk model.

Pro Tips

01
Watch for credit-equity divergences
High-yield investors continuously price default risk and may react to early signs of stress. If HYG/LQD is falling while SPY is making new highs, that divergence is worth flagging — it doesn't guarantee a turn, but it's a meaningful loss of confirmation.
02
Use the 3-year z-score for regime context, the 1-year for tactical timing
A +2σ on the 1-year z-score may just be a normal cyclical tightening. The 3-year z-score tells you whether spreads are extreme by multi-year standards.
03
Don't trade off credit alone — pair with VIX and breadth
Credit is one of three major leading indicators. Confirming signals across all three (credit widening + VIX rising + breadth deteriorating) is far more reliable than any single read.
04
Sticky regimes carry more weight than fast flips
A WIDE regime that's been in place for 30+ days is a stronger signal than one that just flipped today. Watch the "day in regime" counter.
05
When TLT and HYG fall together, it's rates not credit
Credit-driven selloffs show LQD outperforming HYG. Rates-driven selloffs show both LQD and HYG falling together. The TLT/HYG ratio helps distinguish.
06
EM credit (EMB) often cracks first
Emerging-market credit spreads typically widen before US high-yield in global risk-off events. Watch EMB/LQD as an early warning ahead of HYG/LQD.
07
Extreme TIGHT can signal complacency
A +2σ HYG/LQD reading means HY is priced for perfection. Historically, sustained extreme-tight regimes have been followed by sharp reversals.
08
Treat CDS activity as intensity, not direction
A jump in CFTC credit-swap volume can come from protection buying, selling, index rolls, hedging, unwinds, or dealer rebalancing. Use it to identify unusually active risk transfer; use price and spread measures to decide whether that activity is risk-on or risk-off.
09
Senior loans (BKLN) are the floating-rate cousin
BKLN tracks senior-secured floating-rate bank loans. Watch its trend independently — when it diverges from HYG, it can signal credit-quality stratification within the HY market.

Common Issues & Solutions

Why does my chart show no recent stress periods?
Credit stress is rare. Since 2021 — the start of the aligned data window — there have been only a handful of brief WIDE episodes. Most of the time markets are in NORMAL or TIGHT. The page is doing its job by showing you that today is not a stress day.
The data shows yesterday's close, not today's
Daily bars are appended after market close (4 PM ET). Our pipeline runs at 1 PM PT (4 PM ET) and the recompute completes shortly after. Today's bar should be visible by ~5 PM ET on regular trading days.
YTD return looks different from cumulative period return
YTD resets at January 1 each year. The other return columns (1d/1w/1m/3m) are pure rolling lookbacks. Both are correct — they're just measuring different windows.
I clicked a regime label and nothing happened
The regime label is a status indicator, not a link. Click on the time-range selector below it (6M / 1Y / 2Y / 5Y / ALL) to change the chart window.

Frequently Asked Questions

Does this tracker include actual credit default swap data?
Yes. In addition to the daily HYG/LQD ETF proxy, the page includes the CFTC Weekly Swaps Report’s market-facing credit-swaps activity: transaction dollar notional, ticket counts, index/tranche share, cleared share, and gross notional outstanding. It is aggregated activity data rather than a daily CDS closing-spread feed.
Does rising CDS transaction volume mean investors are bearish?
No. Public CFTC volume is not signed as net protection buying or selling. Higher turnover can reflect hedging, index rolls, unwinds, rebalancing, or two-way risk transfer. It tells you that the credit-swaps market is unusually active; HYG/LQD, OAS, or properly modeled CDS prices are needed for direction.
What is a credit spread?
A credit spread is the yield difference between a corporate bond and a comparable-maturity Treasury bond. It compensates investors for taking on default risk. When credit spreads widen, investors are demanding more compensation for risk — which usually signals stress. When spreads tighten, the credit market is healthy.
What is the HYG/LQD ratio and why does it matter?
HYG holds high-yield (junk-rated) corporate bonds; LQD holds investment-grade corporate bonds. The HYG/LQD ratio measures how high-yield is performing relative to investment grade. Rising ratio = HY outperforming = credit conditions tightening = risk-on. Falling ratio = HY underperforming = spreads widening = risk-off.
Why do credit spreads matter to stock traders?
Credit investors continuously price default risk and may react to early signs of stress before equity investors do. Several historical episodes (2007–2008, late 2018, early 2020) saw credit spreads widen ahead of major equity drawdowns. The HYG/LQD ratio is therefore widely watched as one of several leading-indicator candidates — useful as cross-asset confirmation rather than as a standalone signal.
What does "TIGHT" credit mean?
TIGHT means the HYG/LQD ratio is more than +1 standard deviation above its 1-year average. Spreads are compressed, high-yield is outperforming investment grade, and the credit market is in risk-on mode. This is generally bullish for stocks.
What does "WIDE" or "STRESS" credit mean?
WIDE (-1σ to -2σ z-score) means spreads are widening — high-yield is underperforming investment grade. STRESS (z ≤ -2σ) means severe credit stress. Both regimes typically precede or accompany equity-market drawdowns.
How is the z-score calculated?
The z-score is the current HYG/LQD ratio minus its rolling mean, divided by its rolling standard deviation. We compute two z-scores: a 252-day (1-year) for tactical context, and a 756-day (3-year) for regime context. A z-score of +1 means the ratio is one standard deviation above its recent average.
Is credit a leading indicator for equities?
Sometimes, but not always. Several major risk events — including 2007–2008 and late 2018 — were preceded or accompanied by credit-spread widening before the worst of the equity drawdown. Other moves (e.g., the August 2024 yen carry unwind) were primarily volatility-driven and credit lagged. Treat the HYG/LQD ratio as one input alongside VIX, breadth, and price action, not as a standalone forecaster.
What is the difference between HYG and LQD?
HYG (iShares iBoxx $ High Yield Corporate Bond ETF) holds bonds rated below investment grade — BB, B, CCC. Higher yields, higher default risk. LQD (iShares iBoxx $ Investment Grade Corporate Bond ETF) holds bonds rated BBB and above. Lower yields, much lower default risk. The ratio between them measures market risk appetite.
What ETFs are tracked on this page?
Nine credit and Treasury ETFs: HYG (HY corp), JNK (HY bond, alternative), LQD (IG corp), EMB (EM bond), BKLN (senior loans), AGG (aggregate bond), TLT (20+ year Treasury), IEF (7-10 year Treasury), and SHY (1-3 year Treasury). Together they cover the full credit-quality spectrum from cash-equivalent to junk.
How often is the data updated?
The underlying CSVs are refreshed daily after market close (around 1 PM PT / 4 PM ET) directly from the TradeStation market-data API. The recompute and JSON output regenerate within a few minutes after the fetch completes. All ratios and z-scores reflect the most recent close.
Why use ETF proxies instead of OAS spread data?
ICE BofA OAS spread data (the academic standard) is published by FRED with a 1-day lag and is only end-of-day. ETF prices update intraday and reflect real-time market sentiment. The HYG/LQD ratio is a cleaner, more timely proxy for the same underlying signal — and it's tradeable, which OAS data is not.
What is the difference between investment grade and high yield?
Investment grade (IG) = bonds rated BBB- or higher by S&P/Fitch (Baa3+ by Moody's). Lower default risk, lower yields. High yield (HY) = bonds rated below investment grade. Higher default risk, higher yields. The split exists because many institutional investors are mandated to hold only investment-grade debt.
How do I interpret a z-score of +1 or +2?
A z-score of +1 means the current HYG/LQD ratio is one standard deviation above its rolling average — moderately tight. +2 means two standard deviations above — extreme tight, historically associated with peak risk-on conditions and complacency. Negative z-scores are the inverse: -1 means moderately wide, -2 means severe stress.
What does "Risk On" mean in the credit context?
In credit markets, Risk On means investors are willing to lend to lower-quality borrowers at narrower spreads. This shows up as HYG outperforming LQD and the HYG/LQD ratio rising. Risk On in credit is generally consistent with risk-on in equities, FX, and commodities — but credit often gets there first.
Can credit spreads predict recessions?
Credit spreads are widely cited as one of several recession-leading indicators in academic and practitioner research. Most US recessions in recent decades have been preceded by some degree of credit-spread widening, though the lead time and magnitude have varied considerably. The signal also produces false positives — sustained widening that did not result in a recession (e.g., 1998 and 2015–16). Treat sustained STRESS readings as a flag for deeper investigation, not as a standalone forecast.
What is the 30-year "S&P 500 vs credit risk premium" chart?
A long-history overlay: the S&P 500 (log scale, via SPY) plotted against the credit risk premium — Moody's Baa corporate bond yield minus the 10-year Treasury (FRED series BAA10Y), inverted and smoothed with a 3-year moving average so that tight (low) spreads sit high on the chart and line up with equity peaks. It captures the same late-cycle "credit complacency" pattern as a high-yield-spread overlay but with full history back to the 1990s. We use Baa-10Y rather than the ICE BofA high-yield OAS (BAMLH0A0HYM2) because FRED restricted that series to a rolling window starting 2023; the current HY OAS is still displayed for context.
What are CCC junk bond spreads, and why watch them?
CCC & lower is the lowest-rated tier of high-yield ("junk") bonds — the most default-prone borrowers. The ICE BofA CCC & Lower OAS (FRED BAMLH0A3HYC) measures the extra yield investors demand to hold them over Treasuries. Because the weakest credits crack first, CCC spreads tend to widen ahead of broader stress, so CCC spreads blowing out while the S&P 500 sits near highs is a well-watched late-cycle warning. Our chart plots it weekly on an inverted axis against the S&P 500; FRED licensing limits the series to 2023 onward, so it is a recent view rather than a multi-decade one.
Why use Baa-10Y instead of the ICE BofA high-yield spread?
The chart that popularized this overlay used FRED:BAMLH0A0HYM2 (ICE BofA US High Yield OAS). Due to ICE Data Indices licensing, FRED now serves that series only from June 2023 onward, so its multi-decade history is no longer available. Moody's Baa-minus-10-year-Treasury spread (BAA10Y) is daily back to 1986, is not license-restricted, and carries the same cyclical signature — it just measures investment-grade rather than high-yield risk, so the absolute level is lower. We surface today's actual HY OAS alongside the long Baa line.
