Beyond Russian Gas Cuts: The Hidden Drivers of Europe’s Inflation Shock Revealed

A new ECB-linked study finds that Europe’s post-Ukraine inflation surge was driven not only by Russian gas supply cuts, but also by fear-driven stockpiling, global LNG market pressures and investor expectations. The researchers conclude that precautionary demand and market psychology played a far bigger role in pushing inflation higher than previously understood.

A new study by researchers from Danmarks Nationalbank, Bruegel, the European Central Bank and the Leibniz Institute for Financial Research SAFE argues that Europe's recent inflation crisis was not driven only by shortages of Russian gas. The research shows that fear, market expectations and global competition for liquefied natural gas (LNG) also played a major role in pushing prices higher across the euro area.

The study was conducted by Jakob Feveile Adolfsen, Marie-Sophie Lappe, Ana-Simona Manu, Denise Rößler, Fabian Schupp and Arthur Stalla-Bourdillon. Their findings challenge the common belief that the 2022 energy crisis was simply the result of supply disruptions after Russia invaded Ukraine.

The researchers say Europe's gas market changed dramatically in recent years. Earlier, gas prices were often linked to oil prices and had a smaller impact on inflation. But after Europe shifted toward market-based gas pricing, prices became much more sensitive to sudden changes in supply and demand. When Russian gas deliveries started falling in 2021 and dropped further after the war in Ukraine, gas prices surged to record levels, sending inflation sharply higher across Europe.

Fear and Panic Buying Drove Prices Up

One of the study's biggest findings is that fear itself became a major economic force during the crisis. The researchers identified what they call "precautionary demand shocks," meaning companies and governments rushed to secure gas supplies because they feared future shortages.

According to the study, these fear-driven reactions accounted for nearly 40 percent of changes in European gas prices during the crisis period. Countries increased storage levels aggressively, traders competed for supply contracts and markets reacted strongly to uncertainty about future energy availability.

The researchers even suggest that some emergency policies introduced during the crisis may have unintentionally increased market pressure. European rules requiring countries to fill gas storage facilities encouraged buyers to secure supplies quickly, adding to competition in already stressed markets.

The study argues that expectations about future shortages often mattered almost as much as actual shortages themselves.

Russia's Supply Cuts Changed Everything

The paper revisits several major events that shaped the crisis. Russia's reduction of exports through the Yamal pipeline in late 2021 is identified as a major supply shock that sharply increased prices across Europe.

But the researchers say the invasion of Ukraine in February 2022 had a slightly different effect. Physical gas deliveries did not collapse immediately after the invasion, yet prices rose dramatically because markets feared that future disruptions were coming. As a result, the study describes the invasion mainly as a "precautionary demand shock" driven by uncertainty and panic buying.

Later cuts to Nord Stream 1 flows in 2022 again created direct supply shocks, worsening the pressure on European energy markets and increasing inflation further.

LNG Became Europe's Lifeline

As Russian pipeline supplies declined, Europe became increasingly dependent on LNG imports from countries such as the United States and Qatar. The study highlights how global LNG markets became critical for Europe's energy security.

The researchers found that LNG shortages had effects on actual inflation that were almost as strong as pipeline disruptions. However, financial markets seemed to pay less attention to LNG-related risks when forming inflation expectations.

This means investors reacted more strongly to visible pipeline tensions inside Europe than to global LNG developments, even though both had a major impact on real inflation outcomes. The study says this disconnect shows that financial markets may not always fully understand how global energy trade affects inflation.

The paper also notes that competition with Asian countries for LNG cargoes became an important factor in European gas prices. Cold weather or stronger energy demand in Asia could quickly reduce LNG availability for Europe and drive prices higher.

Why the Findings Matter for Central Banks

The study concludes that different types of gas shocks create different inflation effects, and policymakers need to understand those differences more clearly.

Some shocks, especially fear-driven precautionary demand shocks and industrial demand shocks, had strong effects not only on energy prices but also on core inflation, which excludes food and energy costs. This suggests that rising gas prices spread through the wider economy, affecting wages, manufacturing costs and consumer prices more broadly.

The researchers warn that Europe can no longer study its energy market in isolation. Inflation risks are now closely linked to global LNG trade, geopolitical tensions, investor behaviour and market psychology.

Their overall message is simple: Europe's inflation crisis was not caused only by physical gas shortages. It was also driven by fear, uncertainty and global market pressures. Understanding those deeper forces, the study argues, will be essential if Europe wants to manage future energy shocks more effectively.
