Citadel Star Analyst: Understanding the Iran War, "Follow the Troops, Not Twitter"

Questioning AI · Why the Middle East War Escalation Trap Makes the Market Underestimate Persistent Risks?

The Middle East war is reshaping the global market landscape, yet most investors still fail to fully recognize the depth and durability of this crisis.

In a recent report, Citadel Securities analyst Nohshad Shah warned that the scale of this geopolitical shock is large enough to divert global growth and inflation trajectories from their established paths, and that the market’s inertia-driven “buy the dip” mindset is seriously underestimating the consequences of a prolonged energy price shock. His core judgment is succinct: “Follow the troops, not Twitter.”

Shah pointed out that a series of military developments—including the U.S. latest announcement of deploying as many as 10,000 additional troops to the region, Iran’s continued drone and missile attacks, and the Houthi threat to the Mandab Strait—all indicate that the conflict remains mired in an escalation trap, with no sign of a way out.

For markets, the impact of this crisis has already begun to shift from an inflation shock to growth risk. Shah’s analysis shows that in the initial phase of the conflict (from February 27 to March 25), interest rates and the dollar accounted for 56% of the tightening in financial conditions; while in recent times, this structure has reversed—risk assets drove 61% of the tightening, and on Friday during intraday trading, that share briefly reached as high as 78%. This means the market’s pricing focus is moving from the inflation narrative to the growth narrative, and bonds’ role as a hedging tool for risk assets is likely to be re-established.

Escalation Trap: No Good Exit Options

Shah characterizes the current situation as a “classic escalation trap”—both sides escalate, hoping that the final round of pressure will force the other to back down. But each escalation is interpreted by the other side as aggression, triggering larger-scale countermeasures, with the intensity of violence continuing to rise until it surpasses the original strategic gains of the war.

The Mandab Strait is a key bottleneck for global energy trade. Placing it under Iran’s effective control is unacceptable to the U.S. and most countries. At the same time, without security assurances, the Iranian regime is also unlikely to accept any ceasefire proposals put forward by the U.S. Shah believes that this structural dilemma makes it difficult for the conflict to end in the short term.

He emphasized that this crisis is fundamentally different from last year’s tariff shock—tariff shocks are unilateral and financial in nature, whereas the damage to real-economy energy infrastructure and global trade supply chains may require a repair cycle lasting as long as several months or even several years.

Central Bank Dilemmas: Stagflation Risk Emerges

Shah pointed out that this conflict poses a major challenge to central banks around the world, marking a fundamental shift in policy narratives compared with before the conflict.

The current macro backdrop is completely different from 2022: the starting point for policy interest rates is higher, there is no demand release from reopening after the pandemic, excess savings have basically been used up, and a globally coordinated fiscal stimulus is unlikely. Against this backdrop, the real risk is that growth is hit hard while inflation continues to rise—i.e., stagflation.

At present, the market has priced in within-year rate hike expectations for the European Central Bank and the Bank of England to nearly three moves, while the Federal Reserve is expected to pause rate cuts. But Shah warned that if central banks are forced into aggressive rate hikes to prevent an inflation-expectations spiral, it could instead intensify economic and financial pressure and produce highly uncertain second-round effects. His conclusion is: under any scenario—whether central banks tighten proactively or energy shocks drag down demand passively—as long as the war continues, demand destruction will occur.

Energy is AI’s Achilles’ heel; bonds regain their hedging value

Shah specifically highlighted that the AI theme faces unique vulnerability in this crisis because its core pillar is energy. Damage to physical infrastructure, rising premiums for reliable electricity, security risks at data centers in the Middle East, helium shortages, and broader supply-chain disruptions collectively create multiple layers of pressure on the AI investment narrative. He said plainly: “We haven’t come out of the woods yet.”

Shah also observed that the stock-bond correlation has reached extreme readings—on the 21st, the 21-day rolling correlation coefficient briefly touched -0.95 (stocks down, bonds down, meaning yields rising). In history, such extreme values often signal turning points in macro mechanisms.

As growth concerns gradually become the dominant driver of market pricing, Shah has explicitly revised his prior stance. He said that he previously leaned toward being bullish on yields because the market broadly positioned for shorting the inflation tail risk; but now, valuations have adjusted to a new level, and the feedback transmission from rising energy prices toward weakening growth has become more tangible. In this context, long-end fixed-income assets should begin to play their hedging role against risk assets again.
