Sovereign credit ratings have long been associated with economic fundamentals. Today, however, geopolitics is increasingly shaping the credit conversation. International sanctions, once viewed primarily as instruments of foreign policy, now have the potential to influence economic performance, financing conditions and, ultimately, sovereign creditworthiness.

As sanctions become more prominent in international relations, understanding sovereign ratings requires looking beyond traditional macroeconomic indicators to the broader geopolitical forces that shape a country’s credit profile.

From Foreign Policy to Credit Risk

International sanctions are restrictive measures imposed by countries or multilateral institutions to influence the actions or policies of another state. They may take the form of trade restrictions, financial sanctions, asset freezes, investment prohibitions, or limitations on access to international payment systems.

Although sanctions are political instruments, their effects are predominantly economic. They can disrupt trade and investment, constrain access to international finance and weaken foreign exchange inflows, ultimately slowing economic growth and reducing fiscal flexibility. These pressures may also erode external buffers, heighten refinancing risks, and weaken a sovereign’s overall credit profile.

In other words, sanctions do not constitute a sovereign rating factor in themselves. Rather, they influence the economic and financial conditions that determine a sovereign’s creditworthiness.

When Sanctions Become a Credit Event

The impact of sanctions is often gradual but far-reaching. As economic activity slows and external financing becomes more constrained, governments may face rising fiscal deficits, higher borrowing costs, and mounting pressure on foreign exchange reserves.

The experience of Russia following the extensive international sanctions imposed after its 2022 invasion of Ukraine illustrates this dynamic. The sanctions significantly altered the country’s access to international financial markets, restricted a substantial portion of its foreign exchange reserves held abroad, and disrupted international payment channels. Although Russia continued to generate considerable export revenues, these restrictions complicated debt servicing and heightened uncertainty regarding payment mechanisms. These developments contributed to successive sovereign rating downgrades by major international rating agencies, illustrating how geopolitical developments can rapidly reshape sovereign credit assessments. Several agencies subsequently withdrew their ratings following regulatory restrictions and changes to the operating environment.

More Than an Economic Story

Sanctions rarely emerge in isolation. They are often imposed amid armed conflicts, diplomatic disputes, governance concerns, or constitutional crises. These underlying developments may themselves weaken institutional effectiveness, reduce policy predictability, and undermine economic confidence.

For rating agencies, the assessment therefore extends beyond the sanctions themselves. It also considers the broader political and institutional environment in which those sanctions arise and the government’s capacity to respond effectively to the resulting economic pressures.

Why the Impact Differs Across Countries

The impact of sanctions on sovereign creditworthiness is not uniform. It depends on the resilience of the affected economy and the scope of the restrictions imposed.

Countries with diversified economies, strong foreign exchange reserves, prudent fiscal management, and well-developed domestic financial markets are generally better positioned to withstand external shocks. Conversely, economies that rely heavily on external financing, international trade, or a narrow export base are often more vulnerable to prolonged sanctions.

The nature of the sanctions also matters. Targeted measures against specific individuals or entities typically have limited implications for sovereign credit quality, whereas broad financial or trade sanctions affecting an entire economy are more likely to influence sovereign ratings.

Ultimately, sanctions underscore the growing influence of geopolitical developments on sovereign creditworthiness. While they are not a rating factor in themselves, their impact on economic, fiscal, and external fundamentals makes them an increasingly important consideration in sovereign credit assessment.
