Since the outbreak of the Russia-Ukraine war, global financial markets have remained volatile, especially the sharp fluctuations in the foreign exchange market that have left many investors confused. This seemingly regional conflict has, in fact, profoundly impacted the global economy through the chain reaction of “Russia-Ukraine war energy currency fluctuations”. Why has a war had such a far-reaching impact on major currencies such as the euro? The core logic behind this lies in the intersection of geopolitics, the energy crisis, and monetary policy. This article will provide an in-depth analysis of how the war affects the foreign exchange market, reveal the specific pathways of the war’s impact on the euro, and offer strategies to help you navigate this uncertain era and understand the underlying logic behind currency movements during an energy crisis.
War is not merely smoke on the map, it transmits shocks through multiple channels, materially impacting the global economy and financial system, thereby triggering sharp fluctuations in the foreign exchange market. Understanding these transmission pathways is key to grasping current market dynamics. The following three core pathways explain how geopolitical risks are translated into currency movements.
Three Core Transmission Pathways Through Which Geopolitical Conflict Affects the Foreign Exchange Market
When war or major geopolitical conflict breaks out, market uncertainty rises sharply, and investors instinctively seek “safe havens”. This risk-off sentiment drives them to sell higher-risk assets, such as emerging market currencies and equities, and shift funds into widely recognized safe-haven currencies.
Therefore, in the early stages of a war, we typically see currencies such as the US dollar and Swiss franc appreciate against most others. This is not because these economies have suddenly improved, but rather a direct reflection of global demand for safety.
The modern global economy relies heavily on complex supply chain networks. War directly damages production facilities, transportation routes, and disrupts the normal functioning of international trade. When conflicts occur in key raw material exporting countries (such as Russia’s energy and Ukraine’s grain), the impact quickly spreads worldwide.
To respond to acts of aggression, the international community typically imposes severe economic and financial sanctions on the country initiating the war. The effects of these measures are twofold, impacting not only the targeted country but also creating spillover effects on the economies of those imposing the sanctions.
As academic research has pointed out, weaponized interdependence makes economic sanctions a double-edged sword, deeply influencing global capital flows and currency values.

If the war impacts global currencies through risk sentiment and supply chains, its impact on the euro is more direct and severe, with the core trigger being “energy”. The energy crisis triggered by the Russia-Ukraine war acts like a perfect storm, precisely striking the most vulnerable part of the eurozone economy and explaining why the euro has been among the hardest hit in this event.
For a long time, Europe, especially industrial powers such as Germany, has relied heavily on cheap natural gas supplied by Russia. This energy lifeline acted as a lubricant for economic growth in times of peace, but became a chokehold during wartime.
After the outbreak of the war, Russia “weaponized” energy by reducing or even cutting off natural gas supplies (such as through the Nord Stream 1 pipeline) to counter European sanctions. This caused devastating consequences for Europe:
This excessive reliance on a single supplier made the European economy highly vulnerable to geopolitical shocks. The rapid deterioration of its economic outlook became the fundamental reason for the euro’s depreciation.
Energy is the lifeblood of the modern economy, and its price volatility quickly transmits to every sector. For the eurozone, this energy crisis triggered a vicious cycle:

This crisis triggered by Russia-Ukraine war energy currency fluctuations perfectly illustrates how economic fundamentals dominate the long-term trajectory of a currency.
Every global economic shock creates relative winners and losers in the currency market.

In summary, a war not only reshapes the geopolitical landscape but also redefines the relative strength of global currencies, with energy security playing a decisive role in this event.
A: The end of the war will undoubtedly ease market risk-off sentiment and provide short-term support for the euro. However, the euro’s long-term trajectory still depends on deeper structural issues. First, whether Europe can fully resolve its energy dependence and establish a diversified and secure energy supply system is crucial. Second, post-war reconstruction, the lingering effects of high inflation, and potential recession risks will continue to test the eurozone’s economic resilience. Therefore, even if the war ends, the euro may see a corrective rebound, but a return to its former strength will depend on whether its economic fundamentals can achieve substantial improvement.
A: In addition to the euro, currencies of other energy-importing countries have also been significantly impacted. For example, although the Japanese yen (JPY) is considered a safe-haven currency, Japan relies almost entirely on imported energy. The surge in energy prices has led to record trade deficits, severely weakening the yen’s value. In addition, emerging market currencies such as the Turkish lira (TRY), due to their fragile economic structures and high dependence on energy imports, have experienced even more severe depreciation under the dual pressure of the global energy crisis and a strengthening US dollar.
A: For retail investors, it is essential to first understand that geopolitical risks are becoming normalized, and asset allocation should incorporate a global perspective. Second, allocating a portion of assets to the US dollar or US dollar-denominated assets can help hedge against uncertainty. Third, for investors holding non-USD assets, tools such as foreign exchange forwards and options can be considered for risk hedging. Most importantly, avoid making irrational trading decisions during periods of extreme market panic, remain calm, and focus on long-term trends rather than short-term volatility.
In summary, the Russia-Ukraine war is not only a geopolitical conflict but also a profound economic event. By triggering a European energy crisis, it has directly led to the weakness of the euro and intensified volatility in the global foreign exchange market. This conflict clearly demonstrates that in today’s globalized world, there is a tightly interconnected transmission chain between war, energy, and currency. Understanding this complete logic, from geopolitical risk to energy security and then to monetary policy divergence, is key to navigating current market uncertainty. Looking ahead, investors need to continuously monitor shifts in the global energy landscape and the policy directions of major central banks in order to make informed decisions and safeguard their assets in this challenging market.
