Trump may be using Nixon’s ‘madman theory’ – and similar infamy may await

Key event: Iran agreed to reopen the Strait of Hormuz — the chokepoint carrying roughly 20% of world oil — after President Trump threatened to "end its civilization." Tehran is charging $2m per ship transiting the strait, creating a new revenue stream and potential incremental cost/insurance pressure on shipping and oil markets. The agreement lowers the immediate threat of further supply disruption but preserves significant geopolitical and reputational risk, likely keeping markets volatile and prompting a defensive portfolio stance.

Analysis

Political play-acting that weaponizes unpredictability raises persistent risk premia rather than delivering clean terminal outcomes; markets will price that as higher realized and implied volatility across energy, insurance and regional assets for as long as reputation for credible deterrence is ambiguous. Mechanically, this shows up as wider implied vol spreads (expect 30-day Brent IV +5–8 vols vs 60-day as the market front-runs episodic shocks) and higher freight/charter rate convexity because owners demand more upside for tail risk. A sequence of headline-driven escalations tends to reallocate optionality across the energy value chain: midstream and refiners face margin compression from routing and stockpile friction while E&P operators retain asymmetric upside due to operational leverage. That divergence typically plays out over 3–9 months as supply responses (shut-ins, rerouting, bunker demand) and commercial hedges get put in place, so tactical exposure should be calibrated to that window. Strategically, erosion of policy credibility is a multi-year tax on risk assets in the region—higher sovereign spreads, foreign-capital flight and a structural premium on defense and insurance revenues. Near-term catalysts that would unwind these premia are a credible multilateral de-escalation, material intelligence-sharing that reduces asymmetric fear, or a binding logistical fix; conversely, any kinetic shock would crystallize losses within days and amplify tail correlations between oil, EM FX and equity vol.
