The U.S. strike on Iran reported on March 22, 2026 has catalysed a rapid reassessment of strategic energy and maritime chokepoints across the Western Hemisphere and the Persian Gulf. In a note circulated the same week, Zoltan Pozsar of Ex Uno Plures argued that the Trump administration is "methodically building a portfolio of assets" targeting nodes that underpin Beijing's oil imports — specifically naming the Panama Canal, Venezuelan crude flows and the Strait of Hormuz (Ex Uno Plures, March 2026; ZeroHedge, Mar 22, 2026). That sequence of arguments places fiscal and geopolitical risk into a single frame: control or influence over transit points can translate into supply-side leverage over energy-dependent economies. The immediacy of the March 22 action has already been priced into some market indicators and risk premia even as governments and institutional investors scramble to quantify exposure.
This development follows a broader strategic shift in global power dynamics since Russia's full-scale invasion of Ukraine in February 2022, which demonstrated how kinetic conflict can translate quickly into commodity and financial market disruption (Russia–Ukraine conflict timeline, Feb 2022). The United States' military posture in the Persian Gulf — notably the U.S. Fifth Fleet based in Bahrain since 1995 — along with its alliances and sanctions architecture, remains a central instrument of that leverage (U.S. Navy historical records). Simultaneously, the Panama Canal's role as a gateway for both oil products and containerised trade has been highlighted by analysts as a potential Western Hemisphere counterpart to Hormuz in any strategy aimed at constraining rivals' energy security. For institutional investors, the concatenation of kinetic events, policy signalling and infrastructure vulnerability creates distinct scenarios for asset repricing and operational contingency planning.
The immediate market reaction has been heterogeneous: energy futures showed upward repricing in the first 48 hours following the strike, while shipping insurers briefly widened war-risk premiums on Persian Gulf routings. Traders and policymakers are therefore treating the strike less as an isolated event and more as a possible inflection in U.S. grand strategy. For readers seeking further, ongoing coverage of energy-security implications and geopolitical risk frameworks, our published research on energy security and geopolitical risk offers ongoing updates and scenario analysis.
Three quantitative data points frame the current policy and market calculus. First, the International Energy Agency (IEA) and multiple shipping-sector analyses historically estimate that roughly 20% of global seaborne crude oil passes through the Strait of Hormuz at various points in recent years (IEA, 2023-2024 reporting). That makes Hormuz uniquely sensitive: even localized disruptions can shift global refinery feedstock flows and crude price relationships. Second, the Panama Canal — expanded in 2016 to accommodate Neopanamax vessels — remains a critical albeit smaller conduit for Atlantic-Pacific energy trade; the Canal completed its expansion in 2016, materially increasing capacity for larger tankers and container ships (Panama Canal Authority, 2016). Third, the U.S. strategic posture in the region is long-standing: the Fifth Fleet's presence in Bahrain and sustained naval operations in the Gulf have been a constant since the mid-1990s, providing the U.S. with forward options that are both military and diplomatic (U.S. Navy, historical data).
Comparisons sharpen the implications. The Strait of Hormuz's ~20% of seaborne crude flows contrasts with the Panama Canal's smaller but strategically consequential role for flows between the Atlantic and Pacific; while Hormuz is a high-volume chokepoint for Middle Eastern crude, the Panama Canal disproportionately affects VLCC/large crude and refined product arbitrage between U.S. Gulf/Latin American and Asian markets. These are asymmetric risks: a disruption in Hormuz immediately affects crude availability for Asia and Europe, while constraints around Panama create rerouting costs and time-on-water penalties that increase freight and storage demand. Historical precedent — such as tanker rerouting following sanctions or regional tensions in the 2010s — shows that insurance, freight and inventory metrics adjust within weeks, reshaping refining margins and time-charter rates.
Sources and dates matter for institutions calibrating exposure. The Ex Uno Plures note (March 2026) explicitly frames U.S. policy as portfolio-building; the ZeroHedge summary of that note was published on March 22, 2026 and has circulated widely in non-traditional media channels (ZeroHedge, Mar 22, 2026). For independent confirmation of transit shares and infrastructure capacity, institutional investors should review IEA transit statistics, Panama Canal Authority operational reports and U.S. Navy deployment data as contemporaneous inputs to any scenario work. We link to our broader analytical repository for clients and practitioners interested in deeper scenario modelling: geopolitical research.
Energy markets: The most direct transmission channel is energy. If the U.S. widens a policy that strategically targets nodes of China’s crude supply chain, benchmark differentials could reprice. For example, a premium on Middle Eastern grades for Asia — already volatile in prior disruptions — would widen Brent-Dubai discounts and alter Singapore refinery margins. In 2022, sanctions and disruptions reshaped regional spreads within weeks; the same dynamic could reoccur, this time with more deliberate geopolitical engineering in play. Institutional portfolios with concentrated exposure to integrated oil majors, national oil companies with Gulf-linked exports, or refineries with single-source dependency should stress test cash flows against scenarios of 5–15% supply shortfalls through key corridors.
Shipping and logistics: Shipping operators face rerouting costs and insurance shocks. Rerouting around the Cape of Good Hope adds roughly 8–14 days to transit times between the Persian Gulf and Asia and increases bunker fuel consumption; those costs translate directly into higher freight and iron-clad time charter demands. Canal constraints in the Americas produce analogous but different friction: a protracted political contest over access or operational control could force certain classes of tanker and LNG carriers to take longer legs, reducing effective fleet capacity and lifting spot freight rates. Historical adjustments have shown shipping markets can recalibrate supply within 1–3 months, but short-term spikes in delivery times and working capital requirements can be acute.
Regional finance and sovereign credit: Latitude for sanctions and secondary pressure against suppliers or transit-state actors can spill into sovereign credit assessments. Venezuela, for example, is singled out in Pozsar's framing and remains a wildcard given its oil reserves versus current production capacity; any incremental U.S. moves could further complicate Caracas' re-integration into global markets and affect counterparties with exposure to Venezuelan bonds or assets. Similarly, insurance shocks that raise the cost of trade have first-round effects on tradeable sovereign revenue and second-round effects on corporate earnings for energy- and trade-exposed jurisdictions.
Operational risk: Physical disruptions, whether intentional, accidental or punitive, remain the highest-probability near-term outcome for markets sensitive to the March 22 strike. The presence of naval assets reduces but does not eliminate asymmetric risk: mines, harassment of commercial shipping, and cyber actions against port infrastructure are lower-cost options for state and non-state actors to impose friction. Institutional operators should consider scenario-based stress tests that assume 10–30% functional capacity loss at a given chokepoint for 2–12 weeks, modelling impacts on commodity split, freight rates and inventory build/draw dynamics.
Financial risk: Markets have already shown volatility in the immediate aftermath. War-risk insurance premiums in the Persian Gulf broadened, and energy futures exhibited prompt-month contango adjustments reflecting elevated near-term storage demand. Credit risk can follow: trade finance lines, letter-of-credit pricing and working capital metrics for commodity traders and refiners will be sensitive to sustained shipping frictions. For fixed-income investors, sovereigns reliant on oil-export revenues and corporates with long lead-time projects in affected geographies present differentiated duration and liquidity risk that requires active monitoring.
Policy and escalation risk: The more important risk is strategic: if the strike signals a broader, sustained U.S. doctrine to leverage choke points as a tool of great-power competition — a point emphasised in Ex Uno Plures (March 2026) — escalation ladders are non-linear. Actor responses can include strategic hedging (diversifying suppliers), military counterpostures (expanding basing), or alignment shifts (secondary partnerships between China, Russia and regional states). Each response reconfigures the equilibrium in ways that are hard to reverse quickly and that have persistent price and political effects.
Contrary to the prevailing narrative that views the March 22 strike primarily through a short-term risk-premium lens, Fazen Capital views the action as a signal that policymakers are prepared to operationalise a geopolitical supply-chain toolkit over a multi-year horizon. This makes the event less of a one-off volatility spike and more of a policy regime change in which real assets — canals, ports, refineries, and regional alliances — become instruments of statecraft. That shift elevates the value of resilience (diversified logistics, redundant supply contracts, and flexible refining footprints) relative to purely price-driven positions. Institutions should therefore re-weight scenario grids to allocate higher likelihood to durable policy reconfiguration rather than transient disruption alone.
In practical terms, our contrarian calibration emphasizes the long tail: infrastructure assets that look vulnerable on headline risk metrics can acquire strategic value and political protection over time, while ostensibly 'safe' paper exposures may suffer idiosyncratic shocks if they sit in politically contested geographies. For example, logistic hubs that can pivot product flows — through storage capacity or multi-port routing — could see implied option value increase materially under a prolonged strategic posture. These dynamics are not fully priced into many passive indices or traditional credit spreads today, creating opportunities for active risk managers prepared to incorporate geopolitics into capital allocation models.

Near-term (0–3 months): Expect elevated volatility in energy futures and shipping freight indices. If hostilities remain localized, markets will likely price in short-term premia that fade as inventories and rerouting absorb shocks. Monitor insurance premium indices and time-charter rates as leading indicators for supply-chain stress. Historical precedent suggests freight and insurance adjustments manifest within days and normalise within weeks absent escalation.
Medium-term (3–18 months): If the U.S. pursues a discrete strategy of leveraging chokepoints to exert pressure on adversaries, markets may settle into a higher baseline of premia for certain routes and grades. That would render structural changes — reserve optimisation, diversified refining feedstocks, and forward freight agreements — more economically attractive. Sovereigns and corporates with high single-source exposure should be treated as higher idiosyncratic risk in credit and counterparty analyses.
Long-term (>18 months): A durable reordering of geostrategic competition — especially if accompanied by alignment between major powers — could institutionalise new trade corridors and alliances, creating winners and losers across infrastructure, shipping, and energy sectors. Institutional investors should build optionality into physical logistics and financial exposures to capture asymmetric upside and limit tail losses in such a reconfigured landscape.
The March 22, 2026 strike on Iran has shifted the probability distribution for geopolitically driven supply shocks, elevating the strategic importance of maritime and transit infrastructure. Institutional portfolios should treat this as a regime signal rather than a transitory volatility event.

Q: How have historical choke-point disruptions affected commodity prices and insurer behaviour?
A: Historical episodes — for example, tanker disruptions in the Strait of Hormuz in the 2010s and the Suez Canal blockage in March 2021 — produced immediate freight spikes (time-charter and spot rates), temporary increases in war-risk and hull insurance premiums, and prompt reallocation into onshore storage (working inventories rose across refiners). Insurers typically widen premiums within days; the supply-side price effects can persist for weeks to months depending on rerouting capacity and spare refinery margins.
Q: If the U.S. focuses on Panama and Venezuela as levers, what are the practical implications for Asia-Pacific energy security?
A: Targeting Western Hemisphere nodes would primarily affect routing efficiency and arbitrage windows rather than immediate loss of Middle East crude. For Asia-Pacific buyers, the practical impact is twofold: first, higher logistical costs and longer time-on-water for Atlantic-Pacific arbitrage; second, potential reorientation toward long-term contracts with Middle Eastern and African suppliers to minimise exposure. The result is upward pressure on delivered costs and a premium for contracted supply security, distinct from price shocks caused by direct Gulf disruptions.
