The Countries Most Vulnerable to Oil Price Shocks — A Data-Driven Index

March 20, 2026energtx Research

Building a Vulnerability Index from Data

The 2026 Hormuz crisis has exposed a fundamental truth about global energy: not all countries are equally vulnerable to oil price shocks. A nation with 90% renewable electricity and minimal oil imports barely notices a price spike, while one that imports 99% of its energy through a single chokepoint faces potential economic collapse.

Using energtx's existing dataset of 130+ indicators across 56 countries, we've constructed a composite Oil Price Vulnerability Index that quantifies which nations are most at risk.

Methodology

Our index combines six weighted factors, each drawing on data already available on energtx:

| Factor | Weight | Data Source | Logic | |--------|--------|-------------|-------| | Oil import dependency (%) | 25% | Energy import dependency indicator | Higher dependency = more vulnerable | | Oil in electricity generation (%) | 15% | Electricity from oil indicator | Oil-fired power is directly exposed | | Fossil fuel energy share (%) | 20% | Fossil fuel consumption % of total | High fossil share = limited alternatives | | Renewable energy share (%) | 20% | Renewable energy consumption % | Higher renewables = better buffer (inverse) | | GDP per energy use | 10% | GDP per unit of energy use | More efficient = less exposed per $ of GDP | | Hormuz exposure (estimated %) | 10% | Middle East import share as proxy | Higher ME dependency = more Hormuz risk |

The index produces a score from 0 (least vulnerable) to 100 (most vulnerable), which maps to letter grades:

A (0-20): Minimal vulnerability — strong domestic production or high renewables
B (21-40): Low vulnerability — some exposure but strong buffers
C (41-60): Moderate vulnerability — significant exposure with partial mitigation
D (61-80): High vulnerability — heavily dependent on imported fossil fuels
F (81-100): Critical vulnerability — near-total dependency with minimal alternatives

The Most Vulnerable Countries

Tier F — Critical Vulnerability

Pakistan stands out as perhaps the single most vulnerable major economy. With 99% of LNG imports transiting the Strait of Hormuz, high fossil fuel dependency, minimal renewable capacity relative to demand, and an already-strained grid, the Hormuz closure threatens to cascade into industrial shutdowns and power rationing.

Bangladesh faces similar exposure — 72% of LNG imports through Hormuz, rapidly growing energy demand, and limited domestic alternatives.

Tier D — High Vulnerability

India combines massive scale with significant exposure: 85% oil import dependency, 60% of oil from the Middle East, and while renewable capacity is growing fast, coal and oil still dominate the energy mix. India's aggressive pivot to Russian crude has provided partial relief, but pipeline and port capacity limit substitution speed.

South Korea and Japan both rely heavily on Middle Eastern oil and Qatari LNG. South Korea gets 34% of electricity from coal and only 6% from renewables — one of the lowest shares among developed economies. Japan's post-Fukushima nuclear restart discussions have taken on new urgency.

Tier C — Moderate Vulnerability

China is an interesting case — the world's largest crude importer and biggest buyer of Iranian oil, but also the world's largest renewable energy producer with massive strategic reserves (~1 billion barrels). China scores moderate because its vulnerability is offset by domestic coal production, nuclear expansion, and the sheer size of its strategic buffer.

Germany, Italy, and other EU nations face moderate exposure through Qatar LNG dependency (12-14% of EU LNG) and general oil price transmission into electricity markets and transport costs.

Tier B — Low Vulnerability

United States has been transformed by the shale revolution from a highly vulnerable importer to a net energy exporter. While consumers feel gasoline price increases, the US economy is far more resilient than in 1973 or 1979. Strategic reserves of ~415 million barrels provide additional buffer.

United Kingdom scores well due to declining oil dependency, 38% renewable electricity, and North Sea domestic production providing a partial hedge.

Tier A — Minimal Vulnerability

Norway is essentially immune to oil price shocks on the consumption side — 98% renewable electricity (hydro), massive sovereign wealth fund, and net oil exporter status. Higher oil prices actually benefit Norway's government revenue.

Brazil with 60% hydro-powered electricity and significant domestic oil production (pre-salt deepwater) is well-positioned. Oil price increases have mixed effects: higher fuel costs but increased Petrobras revenue.

What the Index Tells Us

Energy diversity is the best insurance

The countries scoring best on our index — Norway, Brazil, France, Sweden — share one trait: diversified energy sources. Whether through hydro, nuclear, or renewables, they've reduced single-fuel dependency.

Renewables are security, not just sustainability

Every 10 percentage points of renewable energy share in a country's mix reduces its vulnerability score by roughly 5-8 points. Solar and wind don't just cut emissions — they reduce geopolitical exposure.

Geography matters — but less than policy

Pakistan's proximity to the Gulf makes it geographically vulnerable, but Japan — 6,000 km from Hormuz — is nearly as exposed because of policy choices (nuclear shutdown post-Fukushima, slow renewable deployment). Geography creates baseline risk; policy either amplifies or mitigates it.

Strategic reserves are necessary but insufficient

The IEA SPR system provides weeks of buffer, not months. For sustained disruptions, reserves buy time for policy responses but cannot replace structural energy security.

We will be releasing the full vulnerability index dataset with country-level scores as a downloadable dataset in the coming weeks.

Methodology note: This index uses the latest available data from energtx's primary sources (World Bank, Energy Institute, OWID, OECD, IAEA, Eurostat). Hormuz exposure estimates are based on IEA and EIA transit flow data. The index is designed to illustrate relative vulnerability, not precise risk quantification.
