A senior trader at Goldman Sachs' derivatives desk has issued a stark warning in his latest report: beneath the market's placid surface, clear cracks are appearing in the bond market, while stock market complacency has reached a level not seen in years.
In his report, the trader notes that typical summer market patterns are fully in effect: cash trading volumes have plummeted since July, the VIX volatility index closed near 14 on Friday, the S&P 500 is within 0.5% of its all-time high, and Goldman's own panic indicator has fallen to single digits—its lowest level since the COVID-19 pandemic.
He believes the market is pricing in a "smooth sailing" earnings season, but "these good times typically don't last long." Currently, there is "carnage" in the bond market, while equities remain oblivious, and the divergence between the two is intensifying. "Sometimes you step on the gas, sometimes you step on the brake." His stance for the near term leans towards the latter.
Bond Market Bleeding, Stock Market Unmoved
The trader points out that last week marked the first time in years that the tension among Goldman's bond traders palpably exceeded that on the equity volatility desk—a situation he describes as "a role reversal at its extreme."
The term used by the bond desk to characterize current price action is "carnage."
The reason is straightforward: a wave of bond issuance from technology companies has met market resistance, succinctly described as "too much, too fast."
Both bonds and stocks are corporate financing tools, but bond buyers are typically more cautious than stock buyers and price in risks earlier. When bond investors start demanding higher yields to purchase debt, it signals declining confidence in that company or industry—an early warning signal in essence.
This is reflected in the Goldman Sachs Ultra Short Corporate High Yield Spread Index (GSUCHS30), which saw its credit spread widen by 22 basis points last week alone. The trader's exact words: "that's a lot."
A credit spread represents the "extra cost of borrowing"—the additional interest a corporate bond must pay compared to risk-free U.S. Treasuries. A larger number indicates the market perceives higher risk in the borrower or an oversupply of bonds with insufficient buyers. A 22-basis-point widening in one week is a significant anomaly for the bond market.
Meanwhile, the S&P 500 traded in a tight 30-point range, seemingly oblivious to these developments.
This is not new; the stock market has a history of ignoring bond market signals until it suddenly reacts en masse. The only question is timing. He states: The equity market will ignore all credit-related signals until it suddenly notices—and then everything goes haywire.
How Indifferent is the Stock Market to Risk?
The numbers speak clearly.
The VIX (fear index) closed at 14, near historic lows. More extreme, short-term implied correlation hit a record low this week. This metric gauges whether stocks will move together; a lower number suggests the market believes stocks are almost immune to systemic, correlated crashes, acting independently. This is the lowest reading on record.
Hedging costs are also remarkably cheap. A one-week straddle on the S&P 500—simultaneously buying a call and a put to bet on a large move in either direction—is currently priced at just 100 basis points, equivalent to the market pricing in "no meaningful event in the coming week."
Another detail: hedge funds were net buyers of stocks last week for the first time in four weeks, but the buying was driven almost entirely by short covering, not active long positioning. The ratio of short covering to active buying was as high as 6.5 to 1. This does not signal returning confidence but rather forced position liquidation.
Single-Stock Option Skew: A Chart You "Can't Unsee"
The trader writes in the report: "Occasionally you see a chart that, once seen, cannot be ignored. This is one of those charts."
He is referring to a chart comparing the average skew of single-stock call options to put options.
Currently, the average skew for single-stock call options is almost flat with at-the-money implied volatility—in other words, the premium for upside optionality has vanished. Meanwhile, the average skew for single-stock put options has fallen to a 10-year low.
This means that at the individual stock level, not only must fundamentals deliver strong results, but even option pricing has fully baked in optimistic expectations—leaving minimal room for error.
The driving force behind this is the continued flow of capital into call options on large-cap tech stocks, with related positioning back near historical highs.
An even more extreme data point: for S&P 500 constituents, the one-month 25-delta call option on a single stock is a full 30 volatility points more expensive than the corresponding index option. This means individual stocks face not only high performance hurdles fundamentally but also extreme upward pressure in option pricing expectations.
Leveraged ETF Expansion: Another Facet of Market Complacency
The trader also highlights another notable structural shift: the expansion of global leveraged ETF assets.
As of the end of June, the notional exposure of U.S. leveraged ETFs had reached approximately $3 trillion. He predicts that when market participants look back on trading history in 2026, "the rise of leveraged ETFs will have its own chapter."
Concurrently, data from Goldman Sachs Prime Brokerage shows hedge funds were net buyers of stocks last week for the first time in four weeks—but the buying impetus came almost entirely from short covering, not active long additions. The ratio of short covering to long buying was as high as 6.5 to 1, triggering the largest single-stock deleveraging in over three months.
