Since US and Israeli forces launched strikes on Iran on February 27, 2026, the entire universe of U.S.-listed country ETFs has bifurcated along a single fault line. On one side: two funds in positive territory. On the other: every other country ETF in the world, deep in the red.

According to Country ETF Tracker data as of March 27 — measured precisely from February 27 closing prices — only the iShares MSCI Saudi Arabia ETF (KSA) and the iShares MSCI Norway ETF (ENOR) have delivered positive returns since the war began. ENOR is up +1.54% since February 27. KSA is up +2.80%. Every other country ETF tracked on countryetftracker.com is negative over the same period. Not most. All of them.

The scatter chart available at countryetftracker.com/Iran-war-market-screener-strait-of-hormuz-crisis makes the signal impossible to ignore: the correlation between each country's energy trade balance (as a percentage of GDP) and its ETF performance since February 27 now stands at 0.585. This is not a stock-picker's market. It is a macro structure trade of historic clarity.

The Main Market Signa

l

The energy trade balance has never been a more powerful predictor of equity market returns than it is right now. Euronews described the dynamic with precision in a March 12 headline: "Oil shock splits the world — who's gaining and who's paying the price?" The answer, rendered in equity market data, is binary: net energy exporters with Hormuz-insulated delivery routes gain; net energy importers pay.

The Strait of Hormuz — the 21-mile chokepoint through which approximately 20% of global crude oil and 25% of global LNG flows — has been effectively shut since February 28. Forbes reported this week that the closure has created "a daily supply deficit of around 15 million barrels of oil, triggering fuel shortages" across import-dependent economies. Countries are responding with fuel rationing, air conditioning bans and compressed work weeks — the kind of demand destruction that translates directly into equity market impairment.

Two countries are exempt from that impairment. Both are large net energy exporters. Both have geographic insulation from the conflict zone — Norway entirely, Saudi Arabia partially through its Petroline west coast pipeline bypass. Both have seen their equity markets rise while every other country ETF falls.

Every other country ETF — negative since Feb 27:

Two entries in this table carry particular analytical weight.

Brazil (EWZ, -4.84%) appears to contradict the energy exporter thesis — and it actually confirms the more precise version of it. EWZ has a strong +16% YTD return, but that was built entirely before the war. Since February 27, Brazil is in the red alongside every other non-ENOR, non-KSA country ETF. Brazil exports oil via Atlantic Ocean routes with zero Hormuz exposure — but it does not receive the Hormuz disruption premium that Norway and Saudi Arabia capture. Norway's pipeline gas fills the LNG vacuum created by the Gulf shutdown. Saudi Arabia's Petroline allows partial oil rerouting. Brazil simply exports at a higher spot price without any volume uplift from the disruption itself.

The Gulf exporters (UAE -14.73%, Qatar -6.86%, Kuwait -5.84%) confirm a critical distinction: being a net energy exporter is necessary but not sufficient. Qatar, Kuwait and UAE all export oil and gas. All three are negative because they export through Hormuz — the disrupted chokepoint — meaning they benefit from higher prices but cannot deliver their product. The conflict-zone risk premium and delivery constraint together more than offset the price windfall.

What Is Driving These Moves

?

The 0.585 correlation between energy trade balance and country ETF returns is not a coincidence. It is the direct mechanical expression of the Strait of Hormuz closure rendered visible in 43 equity markets simultaneously.

The exporter mechanism: When Hormuz disrupts global oil and gas flows, the price of the commodity that insulated exporters sell rises while their delivery volume is unaffected. For Norway, every barrel of North Sea crude and every cubic metre of pipeline gas to Europe generates higher revenue without any supply reduction. Equinor's gas price realisation has risen with European spot TTF prices that have surged since the Gulf LNG shutdown began. The mechanism is clean: price up, volume unchanged, revenue expands directly.

The importer mechanism: Energy-importing countries pay more for every unit of energy they consume. That additional cost flows through three channels: higher consumer energy prices compress household purchasing power; higher industrial energy costs compress corporate margins; and deteriorating current accounts weaken local currencies, which amplifies the energy cost in local currency terms and impairs USD-denominated ETF returns further — a compounding effect that is most severe for emerging market importers like South Korea, India and Indonesia.

Reuters reported on March 16 that the US "is quickly exhausting tools to absorb the Iran war oil shock." For economies with zero domestic production — South Korea, Japan, Vietnam, Thailand — the absorption capacity is effectively zero. Every dollar of higher Brent flows directly into economic impairment, with no domestic production buffer.

Forbes reported this week that countries enforcing "fuel rationing, no AC, and 4-day work weeks" in response to the oil crisis include South Korea, Thailand and Vietnam — precisely the markets whose country ETFs are deepest in the red. The equity market is pricing what the real economy is already experiencing.

South Africa's -20.88% — the worst in the universe — reflects a triple shock unique to its market: energy imports, a historic precious metals collapse (gold -12% month-to-date, platinum -17%, palladium -20% — the worst monthly readings since the 2008 financial crisis), and rand depreciation. Its position at the bottom of the table is not primarily an energy story — but energy costs amplify the precious metals collapse through higher mining operating costs on South Africa's electricity-intensive PGM smelting operations.

Why KSA Leads ENOR Since Feb 27 — But ENOR Leads YT

D

Since February 27, KSA (+2.80%) has marginally outperformed ENOR (+1.54%) on a raw since-war basis. But ENOR's +21.58% YTD dwarfs KSA's +4.94% YTD — because ENOR entered the war with significant pre-existing momentum from January and February's energy market repricing anticipating the conflict.

The post-February 27 data tells a subtler story. Saudi Arabia has partially outperformed Norway over this specific window because oil prices — Saudi Arabia's primary product — have surged more sharply than European gas prices in percentage terms since the war began. Norway's gas price uplift is real but more dampened by long-term supply contracts and storage cushions than the spot crude market.

However, Norway's structural advantage is durability. Saudi Arabia intercepts Iranian drones. Its eastern oil fields are within the conflict's operational radius. Aramco's export terminals have been targeted. Operating in a conflict zone while also benefiting from the price it creates introduces conflict-zone risk that reduces the clean signal KSA might otherwise deliver. ENOR carries zero conflict-zone risk — Norway's production is 5,000 kilometres from the nearest Iranian missile.

The gas volume channel further distinguishes Norway: it supplies approximately 25% of Europe's total natural gas demand via pipeline. When Hormuz disrupts Gulf LNG flows, European buyers have nowhere else to turn quickly and pay higher prices for Norwegian gas — a volume-price double uplift that Saudi Aramco cannot replicate because it exports oil and LNG through Hormuz itself, not gas via pipeline to a captive European customer base.

Three Analytical Implication

s

1. This is not a stock-picker's market. Individual company fundamentals, earnings beats and sector rotation are all secondary to one variable: does the country export energy via Hormuz-insulated routes, or import it? Samsung's Nvidia deals, TSMC's monopoly, Germany's defence rearmament, Brazil's Petrobras earnings — all of it has been overwhelmed by the routing-adjusted energy balance factor since February 27.

2. "Net energy exporter" is not the winning variable. "Hormuz-insulated energy exporter" is. Qatar, Kuwait and UAE are all net energy exporters. All three are deeply negative since the war began. The precise discriminating factor is not just export status — it is the ability to deliver product without transiting Hormuz. Norway can. Saudi Arabia partially can. Everyone else cannot.

3. The 0.585 correlation is the exit signal. When this correlation begins to compress — when energy-importing markets start recovering despite their structural disadvantage — the market is beginning to price a Hormuz normalisation. Monitor the scatter chart at countryetftracker.com/Iran-war-market-screener-strait-of-hormuz-crisis. When the correlation falls below 0.40, the rotation out of ENOR and KSA into the deepest-value importers (EWY at 10.29x P/E, EZA at 11.07x P/E, EIDO at 11.83x P/E) will accelerate.

Conclusio

Frequently Asked Question

s

Which country ETFs are positive since the Iran war began on February 27?

Exactly two, measured from February 27 to March 27 closing prices: KSA at +2.80% and ENOR at +1.54%. Every other U.S.-listed country ETF in the universe is negative over that period.

Why is Brazil negative since the war despite being a commodity exporter?

EWZ is down -4.84% since February 27. Brazil exports oil via Atlantic routes with no Hormuz exposure, but it does not receive the Hormuz disruption premium — the additional volume and pricing uplift — that Norway (via pipeline gas to Europe) and Saudi Arabia (via Petroline rerouting) capture. Brazil benefits from higher spot prices but cannot replace the Gulf LNG supply vacuum the way Norwegian gas pipelines can.

Why are UAE, Qatar and Kuwait negative despite being energy exporters?

All three export oil and gas through the Strait of Hormuz — the very chokepoint that is disrupted. Their product cannot reach customers. They simultaneously absorb higher oil prices in their income statements but face export volume constraints and conflict-zone risk premiums that more than offset the price windfall. Being an energy exporter is necessary but not sufficient; Hormuz-insulated delivery capability is the precise discriminating variable.
