Recent increases in gas prices have reignited concerns among energy traders and government officials in Europe, evoking memories of market turmoil that followed Russia's invasion of Ukraine in 2022. At that time, the continent faced significant challenges in reducing its reliance on Russian gas, resulting in soaring prices.

This situation not only exacerbated inflation but also raised alarms about possible blackouts. High energy costs adversely affected energy-intensive sectors, leading to closures and job losses. The past two winters were navigated successfully, primarily due to unexpectedly mild weather, which allowed for reduced energy consumption. However, the onset of colder weather in November has triggered a new spike in natural gas prices.

On November 21, prices reached nearly EUR49 ($51.6) per megawatt-hour (MWh), marking the highest level in over a year. This surge is attributed to increased heating demands due to low temperatures, compounded by diminished renewable energy supply from wind sources in northern Europe.

Despite the current price increases, analysts note that they remain significantly lower than the peaks experienced in 2022. The overall demand for gas has decreased since that time, providing some context for the recent fluctuations. According to energy analysts, the prices have surged by approximately 40% since mid-September, suggesting a sudden and substantial increase.

Concerns about a colder winter have led to fears that gas inventories, which were well-stocked until recently, could dwindle, potentially igniting a cycle of rising prices. However, analysts argue that the situation is not as dire as it was in previous years, especially given the reduced dependence of many EU member states on Russian gas.

In fact, the share of Russian pipeline gas imported by EU countries plummeted from 40% in 2021 to roughly 9% in 2023. Nevertheless, the presence of Russian liquefied natural gas (LNG) continues to impact the market, accounting for 18% of the EU's total gas imports, reflecting an increase of nearly 5% from the previous year.

As the European market shifts, the last remnants of Russian pipeline gas deliveries appear to be fading. Austria, one of the final countries still receiving such gas, has ceased imports following a legal dispute with Gazprom, the state-owned Russian gas corporation. While Slovakia and Hungary still rely on Russian pipeline gas, forecasts indicate that these arrangements may also come to an end by the close of 2024.

The existing transit deal for Russian gas through Ukraine is set to expire at the end of the year, with Ukrainian officials indicating they do not intend to renew it. Although the TurkStream pipeline will continue to supply Hungary, the cessation of flows through Ukraine will compel central European nations to seek alternative energy sources.

Despite the challenges faced over the past three years, the EU remains a primary customer for Russian gas, purchasing 49% of Russia's LNG exports and 40% of its pipeline gas exports as of October.

In light of these developments, LNG has gained prominence in Europe's energy landscape. With the decline of Russian pipeline gas, LNG now constitutes 34% of Europe's total gas supply, doubling its share from before the conflict began. However, this shift also exposes Europe to greater vulnerability from global market fluctuations.

Experts suggest that while Europe can secure sufficient LNG to meet its energy needs, particularly during a harsh winter, the associated costs may rise significantly as supply struggles to keep pace with demand. This could lead to increased prices, especially if Europe must compete with Asian markets for LNG.

Looking ahead, the implications of these developments could affect gas prices and the availability of supplies heading into the winter of 2025 and beyond. The crucial issue is not merely the availability of LNG but rather the potential price increases that could follow as Europe navigates its energy needs in an evolving global landscape.
