Since Russia’s full-scale invasion of Ukraine in 2022, financial sanctions have become one of the most prominent tools used by Western governments to limit the Kremlin’s economic capacity and constrain its ability to fund the war.

    Russia-Ukraine conflict: The effect on European banks’ stock market returns

    The paper explores the impact of the Russia-Ukraine conflict and associated sanctions on the stock returns of European banks. Specifically, it asks how geopolitical risk and financial sanctions targeting Russia influence the performance of banks across Europe, particularly those with high exposure to Russian markets or proximity to the conflict zone.

    The authors utilize an event study methodology to analyze abnormal stock returns for 100 of the largest European banks, focusing on the onset of the conflict in February 2022. They further incorporate cross-sectional analyses to examine the role of country-specific and bank-specific factors, including exposure to Russia, size, profitability, and institutional ownership, in determining the observed market reactions.

    The results show that European banks, on average, experienced significant negative stock market reactions following the onset of the conflict. Banks with high exposure to Russian markets or listed in Russia suffered the largest losses, driven by financial sanctions, reputational risks, and operational impairments. However, the study finds no evidence of a “proximity penalty” for banks located in countries bordering Russia or Ukraine. Bank-specific factors, such as larger size, higher profitability, and greater operational efficiency, mitigated the extent of negative abnormal returns, indicating resilience in certain institutions.

    Policy implications emphasize the importance of managing systemic risks associated with geopolitical conflicts. Policymakers should aim to strengthen the resilience of financial institutions through enhanced risk management practices and diversification strategies.

  • Weaponisation of finance: the role of European central banks and financial sanctions against Russia

    Weaponisation of finance: the role of European central banks and financial sanctions against Russia

    The role of European central banks in enforcing financial sanctions against Russia has sparked debate over their independence and long-term economic objectives. Traditionally focused on price stability, institutions like the European Central Bank (ECB) found themselves navigating uncharted territory as they became instrumental in implementing economic restrictions following Russia’s invasion of Ukraine.

    This paper examines the implications of central banks engaging in financial warfare, particularly in the context of freezing Russian foreign reserves and restricting access to international financial systems. While these measures were aimed at exerting economic pressure on Russia, their broader consequences include potential damage to financial stability, inflationary risks, and questions over the politicization of monetary policy. The ECB, which has long maintained a mandate centered on economic rather than geopolitical concerns, now faces the challenge of balancing its core mission with new political imperatives.

    A key argument raised by the authors is the risk that using financial systems as tools of foreign policy could undermine their neutrality, potentially prompting actors to seek alternative systems. This could weaken the global financial order, as countries might shift away from established Western financial institutions to avoid future vulnerabilities. The paper also highlights concerns about the ECB’s involvement in sanctions enforcement, noting that it may compromise the institution’s perceived autonomy from political decision-making bodies.

    Generally, the study raises critical questions about the evolving role of central banks in an era where financial tools are increasingly used as instruments of geopolitical power. The findings suggest that while financial sanctions have been somewhat effective in restricting Russia’s access to key resources, their long-term impact on the global financial system and the independence of central banks remains uncertain.

  • Russo – Ukrainian war: Limits of Western economic sanctions

    Russo – Ukrainian war: Limits of Western economic sanctions

    The authors analyze how Western sanctions intended to deter Russia’s war efforts in Ukraine have fallen short of achieving their maximal intended impact. They argue that while sanctions certainly disrupt trade and impose economic pain, they have not forced Russia to abandon its territorial ambitions. The authors attribute this outcome to Russia’s relatively flexible market mechanisms and its ability to reroute its trade flows, rather than solely depending on traditional Western partnerships. As a result, Russia’s economy has shrunk less than many analysts initially predicted.

    A key point is the authors’ focus on “universal substitution,” where the target country’s producers, consumers, and financial institutions adapt to sanctions by finding alternative suppliers, buyers, or production methods. According to the authors, Russia’s system displays moderate capability in this regard. Firms and households, faced with blocked imports from the West, often turn to goods from non-Western nations or expand domestic production. Likewise, Russia’s oil sales, once oriented to Europe, are increasingly redirected to countries such as China, India, and Turkey. This rerouting, combined with a global willingness, at least among certain states, to purchase discounted Russian commodities, helps stabilize Russia’s export earnings.

    The authors note that policymakers in the United States and the European Union originally expected these sanctions to generate substantial pressure on Russia’s government finances and broader economy. Yet because Russia had prepared to withstand certain forms of financial cutoffs and because its home market could switch to local or non-Western alternatives, the pain has proved more manageable than Western leaders anticipated. Even bans on advanced technology and SWIFT access, while disruptive, have not triggered a large-scale collapse of Russia’s gross domestic product.

    On the global stage, the authors assert that sanctions have had unintended knock-on effects. They mention the spike in energy prices when Europe attempted to curtail Russian energy imports, contributing to inflation and hurting lower-income countries reliant on stable commodity supplies. Companies from the West that withdrew in haste from Russia may also have incurred substantial losses or seen their local assets repurposed by Russian counterparts. As a result, while the sanctions are partly successful in signaling political disapproval, the authors caution that they have inflicted collateral damage beyond Russia’s borders.

    Ultimately, the authors conclude that though sanctions do impede certain aspects of Russia’s economy, particularly in areas like technology and finance, they have not undermined the Kremlin’s ability to continue waging war. Looking ahead, they suggest that tighter controls on strategic imports like weaponry or high-end components might be effective, but broad trade bans will not necessarily produce a swift end to the conflict. They also raise the possibility of “smart sanctions,” designed to inflict less harm on outside parties while still restricting Russia’s critical military inputs. In their view, policymakers would achieve more balanced outcomes by focusing on blocking those materials most essential to the war effort, rather than pursuing sanctions so extensive that they harm the wider global economy without decisively altering Russia’s objectives.

  • The impact of financial sanctions on the international monetary system

    The impact of financial sanctions on the international monetary system

    For decades, the U.S. dollar and the SWIFT system have formed the backbone of the international monetary system, serving as critical tools for global trade and finance. However, the financial sanctions imposed on Russia in response to its invasion of Ukraine have raised pressing questions about the stability of this system. This study explores how these measures have affected the global financial order, assessing whether they have reinforced or weakened the dominance of the dollar and the broader international monetary framework.

    The paper examines the impact of these sanctions across three key areas: the role of the dollar as a reserve currency, the stability of exchange rate regimes, and the resilience of global financial infrastructure. While some scholars argue that sanctions have strengthened the dollar’s dominance—forcing some economies to accumulate more dollar reserves to avoid future vulnerabilities—others suggest that the weaponization of financial tools has eroded trust in the dollar as a neutral global asset. The freezing of Russian foreign reserves, for instance, has prompted some emerging economies to diversify their holdings, reducing reliance on U.S. assets and exploring alternative financial networks.

    Beyond currency dynamics, the study also investigates the disruption caused by sanctions on financial infrastructure, particularly Russia’s exclusion from SWIFT. This action has accelerated efforts among sanctioned and non-aligned nations to develop alternative payment systems, such as Russia’s SPFS or China’s CIPS, as well as other discussions about reducing dependence on Western-controlled financial channels. While no immediate alternative to SWIFT or the dollar-dominated reserve system has emerged, the study suggests that these shifts could contribute to a more fragmented global financial landscape in the long run.

    Some implications of these developments remain uncertain. The authors argue that while the U.S. dollar’s dominance is unlikely to be challenged in the near term, growing concerns about financial sovereignty could lead to a more decentralized international monetary system. Emerging markets may respond by tolerating greater exchange rate volatility or increasing capital controls, further reshaping global financial flows. As geopolitical tensions persist, the future of the international monetary system will likely depend on how effectively policymakers balance economic stability with the strategic use of financial sanctions.

  • Does the Russia-Ukraine war lead to currency asymmetries? A US dollar tale

    Does the Russia-Ukraine war lead to currency asymmetries? A US dollar tale

    The study examines how financial and economic sanctions imposed on Russia during the 2022 invasion of Ukraine affected global currency markets, particularly in relation to the U.S. dollar. The authors investigate whether geopolitical uncertainty and financial restrictions led to asymmetric effects across different currencies, reflecting the uneven impact of the conflict on global economies.

    To explore these effects, the researchers employ an event study methodology, analyzing exchange rate data from International Monetary Fund (IMF) member countries. Two key moments serve as focal points: the onset of the Russia-Ukraine war in February 2022 and the Russian Central Bank’s announcement of a ruble-to-gold peg in March 2022. By examining how currencies across various regions reacted, the study assesses the extent of vulnerability and resilience in different economies.

    The findings highlight a stark divergence in currency performance. European currencies, including the Russian ruble, Czech koruna, and Polish zloty, depreciated significantly against the U.S. dollar, largely due to their economic proximity to the conflict and exposure to financial sanctions. In contrast, Pacific region currencies demonstrated resilience, appreciating during the same period. The ruble-to-gold peg stabilized Russia’s currency rather briefly and also had a notable positive spillover effect on certain other currencies. However, while currency markets displayed less immediate volatility compared to stock markets, the study highlights the general economic instability caused by the war.

    From a policy standpoint, the authors’ advice is primarily investor-focused: because a distinct set of currencies proved largely immune to the Russia-Ukraine shock (resilient Pacific and selected ME&A currencies), incorporating these “stable” units into an international portfolio can hedge against war-related volatility and lessen overall risk exposure.

  • Heterogeneous impacts of wars on global equity markets: Evidence from the invasion of Ukraine

    Heterogeneous impacts of wars on global equity markets: Evidence from the invasion of Ukraine

    The paper explores the impact of the 2022 Russian invasion of Ukraine, in context of the associated sanctions on global stock markets. The research question focuses on how the war and the sanctions influence abnormal and cumulative abnormal returns (CARs) across different global equity markets and whether factors like trade dependency or geopolitical alignment drive variations in market responses.

    To answer this, the authors use an event study methodology, analyzing abnormal and cumulative abnormal returns for 47 developed and emerging market indices during specific event windows around the invasion. The study incorporates cross-sectional regression analysis to identify country-specific factors, such as NATO membership, trade-to-GDP ratios, and currency strength, that influence market reactions.

    The results reveal significant heterogeneity in market responses. Developed markets, particularly those in Europe, experienced sharp negative returns due to their economic ties with Russia and proximity to the conflict. Emerging markets, especially those in resource-rich regions like the Middle East, exhibited positive returns in the post-event period, benefiting from rising commodity prices, although a few countries (notably Greece and Hungary) continued to record negative reactions. NATO member countries saw positive post-event CARs, likely reflecting market expectations of increased defense spending and geopolitical stability. The study also finds that countries with higher trade dependencies or stronger currencies experienced more negative returns, underscoring the vulnerability of globalized economies to sanctions-induced challenges.

    These findings suggest that policymakers and investors should account for the vulnerability created by intense trade linkages and for the protective role of reliable security alliances when assessing conflict risk.

  • Does Oil Connect Differently With Prominent Assets During War? Analysis of Intra-Day Data During the Russia-Ukraine Saga

    Does Oil Connect Differently With Prominent Assets During War? Analysis of Intra-Day Data During the Russia-Ukraine Saga

    Resources policy

    The paper explores how sanctions targeting Russia have influenced the dynamics of financial markets, particularly focusing on the interconnections between oil and other major financial assets. The research question centers on whether the war and subsequent sanctions have altered the patterns of risk spillovers and financial connectedness, with oil as a focal point of the analysis.

    The authors employ high-frequency (intra-day) data and utilize a time-varying parameter vector autoregressive (TVP-VAR) model to measure the changes in connectedness between oil and other financial assets, including bonds, bitcoin, gold, stocks, and the U.S. dollar. By comparing pre-war and wartime data, they assess how sanctions, geopolitical tensions, and disruptions in energy supply chains have shifted these relationships.

    The results indicate a significant increase in the connectedness among financial assets during the war compared to the pre-war period. Prior to the conflict, oil primarily acted as a net receiver of spillovers from other markets, reflecting its dependency on broader financial conditions. However, during the war, oil became a dominant net transmitter of risk to other assets, underscoring the centrality of energy markets in financial turbulence caused by sanctions. The findings also reveal heightened volatility in global markets, with assets like the U.S. dollar and gold showing increased sensitivity to oil prices. These changes reflect the critical role of sanctions in reshaping global financial dynamics, particularly as oil prices reached their highest levels in eight years due to disruptions in Russian exports. The policy implications emphasize the need for coordinated international measures to stabilize financial markets during crises. The findings suggest that energy-dependent economies should prioritize diversifying energy sources and building market resilience to mitigate the impact of supply shocks. Additionally, targeted financial interventions, such as interest rate adjustments, could help reduce the cascading effects of increased market connectedness during geopolitical conflicts. By addressing these vulnerabilities, policymakers can better manage the unintended economic consequences of sanctions while maintaining pressure on targeted states.
