Markets were hit this Monday by a fresh escalation of hostilities between the United States and Iran, featuring U.S. strikes against IRGC targets on Larak Island in the Strait of Hormuz, and Iranian retaliatory measures against the United Arab Emirates and Jordan. Markets also had to digest the hawkish speech delivered by Fed Chair Kevin Warsh at Jackson Hole, where he reaffirmed the 2% inflation target and noted that “there is work left to do.” As an immediate result, the probability of a Fed rate hike in September quickly jumped from 36% to 67%.
U.S. Bonds: Normalization, Not Fiscal Alarm
The U.S. Treasury yield touched annual highs, approaching 4.8%, while Japanese sovereign debt (with JGBs near 3%) and German debt (Bunds at 3.3%) were also affected.
News regarding U.S. debt reaching $40 trillion helped amplify the noise, though the numbers point in the opposite direction: the historical correlation between the debt-to-GDP ratio and real rates (TIPS) is negative, because until 2017 the government only increased spending substantially during recessions. The fiscal outlook projected by the Congressional Budget Office (CBO) analysis is not optimistic, but for now, nominal economic growth (according to the New York Fed’s model) far exceeds the 10-year bond yield—suggesting that borrowing costs are not onerous for investment—and, surprisingly, Trump has not fulfilled forecasts, as the budget deficit has remained fairly stable since 2024 despite everything.
For all these reasons, although the uncertainty introduced into the macro picture by the closure of Hormuz, the war in Ukraine, Trump’s fiscal policy, or the Fed’s abandonment of forward guidance has impacted bonds, the rise in yields has less to do with the fiscal picture than with the normalization of growth, inflation, and rate trends.
We are coming off a very peculiar 2010–2020 decade, marked by disinflationary dynamics, household and corporate balance sheet deleveraging, and below-potential growth that led major central banks to adopt zero interest rate policies.
Over the past two years, we have witnessed a macro normalization, with inflation rates slightly above the comfort zone and more robust GDP growth. As a result, 10-year real interest rates in the United States have returned to the range where they fluctuated in the mid-2000s, still well below the levels reached in the 1990s, and the term premium has also regularized.
Despite the noise, bond yields have followed the historical pattern of behavior maintained over the last 30 years relative to interest rate expectations (approximated via SOFR futures). This serves to prove that the yield spike has more to do with a new economic reality than with a higher perceived threat of default associated with U.S. debt.
Similarly, if we model the U.S. bond yield using the latest update of the Fed’s economic projections report, we can conclude that the asset is trading at a certain discount, attributable to the uncertainty affecting energy prices.
However, households and businesses are less sensitive to rate hikes than in the previous decade. Their balance sheets have been repaired since then: household debt as a percentage of GDP hovered around 100% between 2008 and 2009 and today stands at 64.85%, levels not seen since 1997. Furthermore, their leverage ratio relative to net worth is at 60-year lows. In the corporate sector, according to the NFIB survey, management teams show no significant concern over interest payments on their debt.
On the Fed, Inflation, and the Labor Market
Additionally, labor market activity and inflation may ease Warsh’s task in the coming months. Bloomberg’s inflation and job creation surprise indices point to a moderation in the Fed’s hawkish stance, a conclusion similar to that drawn from the Truflation index, which incorporates the prices of millions of daily transactions. The August price index data, set to be published on September 11, will have major implications.
An advance indicator came on Thursday with comments from Christopher Waller, who validated signs of easing inflationary pressures while remaining watchful for evidence confirming a trend toward the 2% target. Following his intervention, futures shifted to price in only a 52% probability of a September rate hike. If the monthly core figure comes in at +0.2% as estimated by consensus economists, the Fed will likely maintain a hawkish tone without altering benchmark rates.
In the labor market, we continue operating in a “few layoffs, few hires” environment, although we may be losing some momentum in recent months. The private ADP job creation indicator has maintained a downward trajectory since March, while the Kansas City Fed labor market conditions indicator has yet to find a floor.
Equities: Resilience and Valuation
All told, investors may be overestimating the impact that a 5% yield could have on stock market performance.
The deleveraging process carried out between 2010 and 2020 substantially improved the balance sheets of households, businesses, and banks, making them more resilient to rate increases. Despite tighter credit, demand remains steady or is even improving.
The S&P 500 P/E ratio has compressed from 23x to 19x, and historical evidence shows that the relationship between moves in 10-year bond yields and valuations is inconclusive.
To the extent that the adjustment toward a normalized rate environment remains gradual, earnings-per-share growth will drive valuations over the coming months.
