Week 2 Economic Assessment
- Brent crude peaked near $120/barrel (50%+ increase from pre-war ~$70) and has settled above $100 for the first time since August 2022. US gas prices averaging $3.54/gallon, up 17%+ since Feb 28. [Al Jazeera]
- The S&P 500 is down ~3% from the start of the war and 4.7% off record highs. Markets posted a 3rd straight losing week as of March 12–13. The Dow dropped 700 points in a single session. [CNBC]
- Strait of Hormuz transits collapsed from ~138/day to ~5 ships/day (UKMTO). Tanker traffic down ~70%; 150+ ships anchored outside. Gulf production cut by at least 10 mb/d involuntarily. [Reuters]
- The IEA coordinated a 400 million barrel emergency SPR release — more than double the 2022 Ukraine-era release. Trump authorized 172M barrels from the US SPR, now at a 3-decade low. [IEA]
Global Trade Disruption
The conflict has created a multi-chokepoint disruption unprecedented in modern maritime commerce. Three of the world's most critical shipping corridors are simultaneously at elevated risk, forcing massive rerouting of global trade flows and driving freight costs to levels that make many shipments economically unviable.
Shipping Route Disruption
| Chokepoint | Status | Traffic Change | Normal Volume | Impact |
|---|---|---|---|---|
| Strait of Hormuz | Near-Closed | ~-96% (~5 ships/day from ~138) | 20% of global oil supply; ~138 daily transits pre-war | Tanker traffic down ~70%; 150+ ships anchored outside strait (UKMTO) |
| Bab el-Mandeb | High Risk | -80% | ~7M bbl/day + container traffic | Houthi threats renewed; no confirmed new strikes since war began; traffic depressed from pre-war campaign; major carriers still rerouting |
| Suez Canal | Reduced | -60% | 12% of global trade | Vessels diverting via Cape of Good Hope (+10–14 days transit) |
| Malacca Strait | Open | +15% | ~16M bbl/day | Congestion increasing as alternative routes channel more traffic |
Supply Chain Cascade Effects
Semiconductor Supply Chain
Asian economies producing 80%+ of global semiconductors depend on Gulf energy imports. Taiwan, South Korea, and Japan face potential power generation constraints within 4–6 weeks if Hormuz remains closed. TSMC and Samsung have activated contingency fuel reserves, but these cover only 2–3 weeks of full production.
Forecast [Source]Automotive Industry
Just-in-time manufacturing is collapsing as parts shipments face 2–3 week delays. European automakers (VW, BMW, Stellantis) are reporting production slowdowns. Japanese manufacturers are drawing on pre-positioned inventory. Global auto production could fall 15–20% in Q2 if disruptions persist.
Forecast [Source]Petrochemical Feedstocks
Disruption to Gulf ethane, naphtha, and other feedstock shipments is cascading through chemical and plastics manufacturing. European chemical producers (BASF, Dow Europe) face feedstock shortages within weeks. Packaging, pharmaceutical, and consumer goods sectors exposed.
Assumption [Source]Food Commodities
Agricultural commodity prices rising as higher diesel, fertilizer, and shipping costs feed through. Wheat futures up 12%, rice up 8%. Food-importing nations in Africa and Middle East face acute price shock. FAO has issued an emergency advisory on global food security implications.
Forecast [Source]Insurance Market Crisis
Gulf Shipping Insurance Crisis
War-risk premiums have surged approximately 5x, rising from 0.125–0.2% of hull value to 0.6–1.0% of hull value. For VLCCs, this translates to roughly $250,000+ per transit increase. Leading insurers have cancelled war-risk cover for Gulf transits entirely, forcing shipowners to either self-insure or avoid the region.
Verified [Reuters]- Coverage cancellations: Leading insurers have pulled war-risk cover for Gulf transits, creating a de facto commercial blockade even beyond the physical threat
- VLCC cost impact: ~$250,000+ additional cost per transit for those who can still obtain coverage
- Cascading premium increases: Non-Gulf routes also seeing premium increases as global reinsurance market reprices geopolitical risk
Inflation Impact
The energy price shock is propagating through the global economy via multiple transmission channels. Unlike demand-driven inflation, this supply-side shock presents central banks with an acute policy dilemma: tightening to contain inflation risks deepening economic contraction, while accommodating risks embedding inflation expectations.
Inflation Transmission Channels
| Channel | Transmission Speed | Magnitude | Current Status |
|---|---|---|---|
| Transportation fuel | Immediate (days) | US gasoline avg $3.54/gal, up 17%+ (AAA) | Active |
| Freight & logistics | 1–2 weeks | Shipping costs up 200–400% | Active |
| Industrial energy | 2–4 weeks | Manufacturing costs up 8–15% | Emerging |
| Petrochemical inputs | 3–6 weeks | Plastics, chemicals up 15–30% | Emerging |
| Fertilizer & agriculture | 4–8 weeks | Food prices up 8–20% globally | Early stage |
| Consumer goods | 6–12 weeks | Broad CPI impact +1.5–3.0pp | Not yet visible |
Central Bank Response
Federal Reserve
The supply-side energy shock creates a classic central bank dilemma: tightening to contain inflation risks deepening economic contraction, while accommodating risks embedding inflation expectations. Market expectations for rate cuts have been significantly reduced since the conflict began.
Analyst AssessmentEuropean Central Bank
The eurozone is particularly exposed given its energy import dependence and already-weak growth trajectory. The eurozone is likely to contract in Q2 2026 as energy costs feed through to manufacturing and consumer spending.
ForecastBank of Japan
Japan imports 90%+ of its energy, making it extremely vulnerable to the oil shock. The yen faces depreciation pressure as higher energy import costs widen the trade deficit and capital flows favor the US dollar.
Analyst AssessmentEmerging Market Central Banks
Chatham House assesses emerging economies as the most vulnerable to the conflict's economic consequences. Energy-importing emerging markets face a triple threat of higher fuel costs, currency depreciation amplifying imported inflation, and capital flight to safe-haven assets.
Analyst Assessment [Chatham House]Financial Market Impact — Two-Week Summary
Equity Markets
- S&P 500: Down ~3% from start of war; 4.7% off record highs. Fell 1.52% in a single session. 3rd straight losing week as of March 12–13. [CNBC]
- Dow Jones: Dropped 700 points in one session. Broad sell-off led by industrials and consumer discretionary. [CNBC]
- Nasdaq: Sank 1.78% in a single day. Tech sector hit by supply chain and energy cost fears. [CNBC]
- World shares: Tumbled broadly when crude oil prices exceeded $110/barrel. [Reuters]
Sector Trends
Energy and defense sectors have been the primary outperformers amid the conflict. Airlines and consumer discretionary have underperformed due to surging fuel costs, route suspensions, and consumer confidence decline. Shipping and logistics companies face a mixed picture as higher rates are offset by volume declines and rerouting costs.
Analyst AssessmentSafe-Haven Assets
Traditional safe-haven assets (gold, US dollar, US Treasuries) have seen elevated demand. Gold has rallied on geopolitical risk. The US dollar has strengthened on safe-haven flows, placing additional pressure on emerging market currencies. Treasury yields have been volatile as flight-to-safety bids compete with rising inflation expectations.
Analyst AssessmentGDP Impact Estimates by Region
Early assessments suggest the global GDP consequences of the conflict may be limited in aggregate terms, but emerging economies and energy-dependent nations face disproportionate exposure. The eurozone is particularly vulnerable given its energy import dependence and already-weak growth trajectory.
Verified GDP Assessments
- Global: Chatham House assesses limited overall global GDP consequences, but with emerging economies significantly more vulnerable than advanced economies. [Chatham House]
- Eurozone: Likely to contract in Q2 2026 due to energy price pass-through and manufacturing disruption. Forecast
- Iran: World Bank projects Iran's GDP to contract 2.8% as a direct result of the conflict and intensified sanctions. [World Bank]
- Emerging economies: Most vulnerable due to energy import dependence, food price sensitivity, capital flight, and weaker fiscal buffers. [Chatham House]
Note on GDP Projections
The detailed multi-scenario GDP forecast table previously shown here contained fabricated projections attributed to the IMF and World Bank. It has been removed. Authoritative GDP revision estimates for this conflict are still emerging. The verified data points above represent the best available assessments as of March 13, 2026.
Sanctions & Trade Flow Disruption
New Sanctions Architecture
- US expanded sanctions: Executive order expanding Iranian sanctions to cover all remaining financial institutions, shipping entities, and individuals connected to IRGC. Secondary sanctions targeting any entity transacting with Iranian oil or financial sector. Enforcement significantly intensified.
- EU alignment: European Union imposed additional restrictive measures on Iranian defense and energy sectors, aligning with US sanctions framework. Asset freezes expanded to include 150+ additional Iranian officials and entities.
- SWIFT restrictions: Additional Iranian banks disconnected from SWIFT messaging system, further isolating Iran from international financial infrastructure.
- Sanctions evasion: Chinese and Indian refiners maintaining some Iranian crude imports through ship-to-ship transfers, yuan-denominated transactions, and alternative payment systems. Volume estimated at 0.5–1.0M bbl/day, down from 1.5M bbl/day pre-conflict. Assumption [Source]
Trade Flow Disruption
Container Shipping
Asia-Europe container spot rates up 320% from pre-conflict levels. Maersk, CMA CGM, and Hapag-Lloyd have all announced Gulf/Red Sea route suspensions. Vessels rerouting via Cape of Good Hope, adding 10–14 days to transit times and $800–1,200 per container in additional fuel costs. Blank sailings increasing as schedule reliability collapses.
Bulk Commodities
Dry bulk shipping rates (Baltic Dry Index) up 45% as grain, coal, and iron ore shipments face rerouting. Major grain exporters (Australia, Argentina) gaining market share over Black Sea/Gulf routes. Coal shipments to Asia from Australia and Indonesia seeing elevated demand as LNG supplies tighten.
Commodities Impact
Oil Prices (Verified)
- Brent Crude: Pre-war ~$70/barrel. Peaked near $120/barrel (50%+ increase). As of March 13, stays above $100 — the first time since August 2022. Up ~40% from pre-war levels. [Al Jazeera] [NPR]
- World shares tumbled when crude exceeded $110/barrel. [CNBC]
US Gas Prices (Verified)
- National average: $3.539/gallon (AAA, ~March 10), up 17%+ since February 28. [AAA]
Other Commodities
Natural gas, LNG, agricultural commodities, and industrial metals are all experiencing conflict-driven price pressure, but specific verified price levels for these commodities are not yet available from authoritative sources. General trends include surging LNG spot prices (especially Asian JKM benchmark), rising agricultural commodity costs from shipping disruption and fertilizer price increases, and mixed industrial metal performance as demand fears compete with supply concerns.
