Stock and bond markets diverge with yields at 15-year highs

A rare battle is unfolding within financial markets as the conflict in Iran forces a stark disagreement between stock and bond investors. The bond market is pricing in the highest inflation risk in years, bracing for imminent rate hikes, while equity valuations imply that slowing economic growth will ultimately cap borrowing costs and perhaps even trigger rate cuts.

"Equity investors are optimists, focused on future profits, while bond investors are entirely focused on protecting themselves from inflation," said Kevin Thozet, a member of the investment committee at Carmignac. "This explains part of the gap between the two."

The divergence is clear in the data. In Europe, interest rate swaps are now pricing in three European Central Bank rate hikes this year, and Germany's 10-year bund yield touched a 15-year high on March 27. In contrast, the Stoxx Europe 600 index trades at roughly 15 times expected earnings, well above its 20-year average, while the S&P 500's cyclically-adjusted P/E ratio remains near historic highs above 38.

The resolution of this conflict will be dictated by incoming economic data and central bank actions. If inflation remains stubbornly high as bond traders fear, elevated stock valuations face a dual threat from rising rates and falling profits. If growth falters as equity investors expect, the bond market's aggressive pricing will be forced to unwind.

Bond Markets Price a 2022 Inflation Repeat

The bond market's sharp reaction is a direct mapping of recent history. Fixed income investors are pricing the inflationary impact of the Iran conflict as a repeat of the consequences seen after Russia's invasion of Ukraine four years ago, when soaring energy prices drove eurozone inflation to record highs and forced the ECB into its most aggressive hiking cycle ever.

"I think the price reaction is particularly violent in the fixed-income market," said Amélie Derambure, a senior multi-asset portfolio manager at AXA Investment Managers. "The equity market is still uncertain about the economic consequences of the conflict, but the bond market is already pricing in the 2022 scenario." This view is echoed by major asset managers like BlackRock, who are reportedly betting on yields climbing even higher.

Equity Markets Bet on a Growth Slowdown

The logic in the stock market is a mirror image. Equity investors believe that a sustained geopolitical crisis will drag on economic activity, leaving central banks with little room to tighten policy. "We clearly don't think there will be two rate hikes, let alone three," said Karen Georges, an equity fund manager at Ecofi, calling the divergence "market schizophrenia." She added that "if growth is substantially impacted, one could even imagine a rate cut before the end of the year."

This view is supported by a long history of investors treating geopolitical shocks as temporary disturbances. According to George Nadda, a portfolio manager at Altana Wealth, data from the Gulf War, the Iraq War, and the 2022 Ukraine conflict shows that while oil prices often spike, stock markets typically recover and post gains within six months of the initial event. This experience underpins the reluctance of analysts to lower earnings forecasts, with S&P 500 profit estimates actually rising ahead of the April earnings season.
