When a signal that bond traders have spent years explaining away suddenly becomes unexplainable, a certain kind of unease descends upon them. Since mid-March, when the 2-year Treasury yield surpassed the federal funds rate target and the Treasury curve resumed its flattening, that sentiment has been subtly permeating fixed-income desks. This pattern carries a particular and unsettling familiarity for anyone who was paying attention in 2006 and 2007. The last time this particular configuration appeared in any sustained way was the run-up to the 2008 financial crisis. By persuading themselves that the signal didn’t mean what it had historically meant, people lost a lot of money that time.
It is difficult to disentangle the current context from the events in the Persian Gulf. In March, as U.S.-Israeli military operations intensified attacks on energy infrastructure throughout Iran and the surrounding region, Brent crude, the global oil benchmark, momentarily surpassed $119 per barrel. For a moment, West Texas Intermediate surpassed $100. These are not insignificant figures.

At that price, oil is essentially a tax on all economic sectors at once, affecting consumer spending power, corporate margins, manufacturing inputs, and transportation costs. After lying dormant for the majority of the 2010s, the term “stagflation” is once again being used in Federal Reserve meeting rooms and on trading floors. Because raising rates to combat inflation runs the risk of stifling growth and lowering them to safeguard growth runs the risk of unleashing more inflation, this type of economic environment makes the standard policy tools less effective. There isn’t a clean move.
Despite its unglamorous image, the junk bond market is typically more truthful about these circumstances than practically any other indicator. In contrast to equity markets, high-yield debt—bonds issued by companies with lower credit ratings that carry higher interest obligations in exchange for investor access—is sensitive to economic stress, at least initially.
Spreads increase, liquidity decreases, and the market as a whole signals that something in the underlying economy is beginning to falter when the companies borrowing at 8 or 10 percent begin to appear less likely to make those payments. It appeared before the oil shock recession of 1973. It appeared prior to 1980, 1990, the dot-com bust in 2001, 2008, and once more prior to the contraction of 2020. It’s not a coincidence. That’s a pattern, and in the credit markets, patterns typically have significance.
It’s important to keep in mind that the junk bond market is a relatively recent development. The market as a whole was worth roughly $10 billion in 1979. After Michael Milken and Drexel Burnham Lambert made high-yield financing a Wall Street religion, it reached $189 billion by the end of the 1980s, growing at a rate of about 34 percent per year for ten years.
Scandals, collapses, and ultimately Milken’s federal indictment accompanied that expansion. However, it also established a real, liquid market for corporate debt, providing investors and economists with a real-time window into the health of corporations. It usually indicates that there is a problem within the building when that window clouds over.
The combination of pressures arriving at the same time is what distinguishes the current moment from the false alarms of the previous few years. When 3-month Treasury yields surpassed 10-year yields in October 2022 as markets priced in the Federal Reserve’s aggressive rate-hiking campaign, the yield curve first inverted. The inversion persisted for more than three years, the longest period since at least the late 1960s, and the recession it was supposed to foretell did not occur for the majority of that period.
Whether the signal was broken was a topic of debate among economists. Some claimed that structural changes in the post-pandemic economy rendered earlier indicators inaccurate. They might have been partially correct. However, the Fed now faces the possibility of raising rates in 2026 to control an inflation spike brought on by a military conflict, which somewhat alters the calculation when an oil shock is layered on top of an already strained credit environment.
In some parts of the market, there’s a sense that the signal isn’t crying wolf this time. Bond volatility has surged to levels that RSM analysts have characterized as typical of previous instances of true financial stress—that is, the deeper, slower fear of a system beginning to price in actual economic harm rather than the normal anxiety of a rate cycle. The fact that global bond yields have fallen to their lowest level since September 2022 may seem comforting, but it is actually a sign of a flight to safety rather than optimism. Investing in government bonds is not a sign of confidence. It indicates that investors are becoming wary of everything else.
All of this is being observed by the Federal Reserve. It’s always the case. However, the Fed’s options are clearly getting smaller in a way that hasn’t happened in a number of years, and the organizations that have traditionally been the most trustworthy at spotting problems early—the credit spread analysts, the junk bond desks, and the people tasked with pricing the likelihood of corporate default—are no longer providing comfort. History doesn’t exactly repeat itself.
However, the current signal has a history that makes it hard to ignore, and the circumstances surrounding it are not particularly better than those that preceded the previous six recessions. Whether that ends badly is still up in the air. However, it’s difficult to ignore the fact that those who are most paid to observe these things are doing so.
