The Global Tremor: How Wars and Economic Sanctions Reshape the Banking System

The interconnectedness of the global financial system means that geopolitical conflicts and the imposition of economic sanctions, once considered isolated national tools, now send powerful tremors across the entire international banking landscape. These measures, designed to exert pressure on targeted states, inevitably create ripple effects that impact financial institutions far beyond the immediate conflict zones. The recent sanctions against Russia, particularly the restrictions on its access to the SWIFT messaging system, serve as a stark case study of how these actions fundamentally alter global banking operations, challenge financial stability, and accelerate shifts in the international financial architecture.

Disrupting Cross-Border Payments: The SWIFT Factor

Perhaps one of the most potent tools in the arsenal of economic sanctions is the restriction or outright ban of a country’s access to the Society for Worldwide Interbank Financial Telecommunication (SWIFT). SWIFT is not a payment system itself, but rather a secure messaging network that enables financial institutions worldwide to send and receive information about financial transactions in a standardized and reliable environment. It underpins the vast majority of international wire transfers and trade finance.

The decision by Western nations to disconnect several major Russian banks from SWIFT in response to the 2022 invasion of Ukraine was widely dubbed the “nuclear option” of financial sanctions. The immediate impact on Russia was severe: it became exceedingly difficult for sanctioned Russian banks to conduct cross-border payments, settle international trade, and access foreign currency. This led to a significant depreciation of the ruble, capital flight, and runs on Russian banks in the initial days.

However, the SWIFT ban also had broader implications for the global banking system. For banks in countries that maintained trade or financial ties with Russia, processing payments became significantly more complex, time-consuming, and costly. It forced a search for alternative payment channels, including bilateral agreements, direct bank-to-bank communication, or the use of payment systems in countries not participating in the sanctions. This created inefficiencies, increased operational risks for banks involved in such transactions, and highlighted the reliance of the global system on a single, dominant messaging network. It also spurred interest in and development of alternative national or regional payment systems, such as Russia’s SPFS and China’s CIPS, potentially leading to a more fragmented global payments landscape in the long run.

Freezing Assets and Limiting Liquidity

Beyond SWIFT, financial sanctions frequently involve the freezing of assets belonging to sanctioned individuals, entities, or central banks held in foreign jurisdictions. This has a direct and profound impact on the liquidity and solvency of banks with exposure to these assets. When a country’s central bank reserves are frozen, as was largely the case for Russia’s substantial foreign currency reserves, it severely impairs its ability to support its currency, manage its economy, and prevent financial contagion.

For international banks, freezing assets necessitates meticulous due diligence and compliance efforts to identify and block sanctioned accounts. This increases compliance costs, exposes banks to legal and reputational risks if they fail to comply, and can lead to complex legal battles over the ownership and release of frozen funds. Furthermore, the uncertainty surrounding the ultimate disposition of frozen assets can create systemic risk, particularly if large volumes of assets are involved or if there are concerns about the precedent set for sovereign reserves. Banks with significant lending or investment exposure to sanctioned entities may face increased credit risk and potential write-offs, impacting their profitability and capital adequacy.

Market Volatility and Investor Confidence

Geopolitical conflicts and the imposition of sanctions invariably introduce significant market volatility. Investors react to heightened political risks, supply chain disruptions, and fluctuating commodity prices. This volatility can manifest in sharp movements in currency exchange rates, bond yields, and equity markets, directly impacting banks’ balance sheets and investment portfolios.

Banks holding significant sovereign debt of sanctioned nations, or those with large exposures to industries heavily affected by sanctions , face increased market risk. The uncertainty can also lead to a flight to safety, drawing capital away from perceived riskier markets and potentially causing liquidity pressures in less developed economies, as seen with the impact of US interest rate changes. Eroding investor confidence can make it more challenging for banks to raise capital, issue debt, or attract deposits, particularly for those operating in regions deemed geopolitically unstable.
