Iranian President Pens Open Letter to American People

Iranian President Masoud Pezeshkian published an open letter to the American public denying Iranian aggression and accusing the U.S. and Israel of manufacturing a threat, released roughly one month after initial U.S./Israeli strikes that began the war. Expect risk-off market dynamics and elevated volatility across global assets—notably energy and defense sectors—and heightened U.S. political risk as President Trump readies a public update; polls indicate most Americans disapprove of the conflict.

Analysis

The immediate market reaction is a classic risk-off pivot: safe-haven assets and defense exposure rerate higher while mobility and discretionary sectors face headwinds. Beyond the obvious defense winners, expect a durable reallocation of government capex — NATO and Gulf partners typically accelerate procurement cycles by 12–24 months after regional shocks, which favors suppliers of precision-guided munitions, radars, and sustainment services (higher margin, multi-year revenue visibility). Shipping and insurance costs for Persian Gulf routes can jump 10–25% within weeks of sustained harassment, creating a short-term supply-chain tax on European and Asian exporters of energy-intensive goods. Secondary effects will show up in credit and FX: banks with Gulf connectivity see CDS widen and correspondent banking frictions rise, pressuring short-term FX liquidity in frontier/EM credit markets over the next 1–3 quarters. Sanctions and export-control tail risks raise the probability of targeted technology embargoes; that benefits domestic substitute suppliers in allied jurisdictions while accelerating onshoring discussions in semiconductor capital equipment and defense electronics. Politically, prolonged conflict compresses fiscal flexibility in democracies — expect added support for defense budgets at the margin and delayed green-infrastructure rollouts in budgets for 12–36 months. Catalysts and reversals are concrete: headline de-escalation (ceasefire diplomacy, major-power mediation) or a meaningful SPR release/strategic oil diplomacy could normalize energy and risk sentiment within 30–90 days. Conversely, strikes on maritime chokepoints, major energy infrastructure, or widening of sanctions to include secondary-targeted buyers would sustain volatility and push markets further into risk-off. Monitor shipping insurance hull rates, GCC sovereign CDS, and multi-week shifts in US Treasury real yields as early indicators to scale positions.
