Unveiling Hidden Trade: How Mirror Data Sheds Light on Global Commerce

In the vast world of trade data, about 15% of global trade remains hidden due to underreporting or delays in data disclosure. Fortunately, there are methods to uncover this “dark matter” and gain accurate insights into trade flows and trends.

Just as astronomers infer the existence of unseen planets and black holes by measuring their gravitational effects, the Observatory of Economic Complexity (OEC) uses a strategy called Mirror Data. This approach reverses reported trade data from partner countries to estimate exports and imports for non-reporting nations.

The Scope of Missing Trade Data

There is significant darkness in global trade data. For example:

  • Ecuador has not updated its export data since December 2021.
  • Russia stopped reporting trade statistics in early 2022.
  • Taiwan and several other nations only provide aggregated figures, without country or product breakdowns.

Due to lack of disclosure and incomplete reporting, 15% of global trade—worth $4.8 trillion—remains in the shadows.

How Mirror Data Fills the Gap

Mirror Data illuminates hidden trade using a simple principle:
➡️ Every export from one country is an import into another.

By analyzing import data from well-reporting countries like the U.S., China, Germany, and Japan, we can reconstruct the trade activities of nations that withhold or delay their data.

For example, even if an oil-producing country delays reporting its exports, major importers like China, Spain, and the U.S. report their oil imports accurately. This allows us to estimate export volumes, track market destinations, and reveal regional trade patterns.

Case Studies: Real-World Applications of Mirror Data

🔹 Angola’s Oil Exports:
Despite reporting delays, Mirror Data reveals Angola’s oil exports remained steady in 2024. Import records from China, Spain, and the U.S.—which account for 63% of Angola’s oil exports—indicate that 275 million barrels worth $25.5 billion were imported in the past year.

🔹 Russia’s Natural Gas: A State Secret Revealed
After Russia stopped publishing trade data in 2022, Mirror Data from Europe and China—Russia’s top gas importers—showed a 70% decline in exports compared to pre-invasion levels.
📊 125 billion cubic meters of Russian gas were imported in the first half of 2024, valued at $35 billion—even without direct Russian reporting.

Expanding Global Trade Coverage

At OEC, Mirror Data has increased global trade coverage from 60% to over 85% in the past year.
💡 Recent additions include granular sub-national data from Portugal and Italy, enhancing our understanding of regional trade flows.

This enhanced global dataset empowers businesses, policymakers, and researchers with deeper insights for better decision-making. Mirror Data is proving invaluable in filling critical gaps in trade reporting, ensuring a clearer, more transparent picture of global commerce.

From Shadows to Transparency

Mirror Data is particularly powerful in monitoring underreported trade.
🌍 In Africa, South Africa is the only country that provides detailed, timely trade data. However, Mirror Data helps uncover trade patterns across the continent, revealing key commodity trends.

📌 Key Findings from Africa’s Hidden Trade:
✅ Cobalt Exports: African nations exported 170,000 metric tons of cobalt in 2024—74% of global supply—according to partner country import records.
✅ Trade Trends: Cobalt exports grew by 17% in 2023 and continued rising in 2024, driven by mine expansions. However, cobalt prices fell by 5% in Q2 2024 due to increased supply.

The Future of Trade Transparency

Mirror Data is transforming how we track global trade, revealing insights previously hidden in political opacity and statistical blind spots. As more nations restrict access to trade information, Mirror Data is becoming a critical tool for businesses, investors, and policymakers seeking a clear and accurate view of the global economy.
