The Limits of Sanctions Learning Effects: Accumulated Distress in Russia's Wartime Finance and Complex Financial Risk

1. Background

As Reuters reported on July 6, 2026, that a confidential report by a European national intelligence agency (“Note on the probability of a banking crisis in Russia in 2026”) warned of the possibility of a banking crisis, the inherent risks of Russia’s wartime financial system are coming to the fore. The fact that the likelihood of a banking crisis was addressed through a confidential document from a European intelligence agency suggests that the geopolitical spillover could be significant.

In response to the prolongation of the wartime system, the Russian government has pushed ahead with subsidized loans, loan restructuring, and government-supported credit provision in order to sustain defense companies and major state-led projects. According to the UNN reporting narrative, these measures are analyzed as having resulted in shifting the burden of war costs onto Russian credit institutions.

In addition, macroeconomic downside pressure also appears to be intensifying. The GDP growth forecast for 2026 was lowered from the previous 1.3% to 0.4%, and the forecast for 2027 was lowered from the previous 2.8% to 1.4%. In this regard, some domestic and foreign reports are treating concerns over distress in Russia’s banking sector together with real-economy pressure trends such as fuel shortages.

2. Analysis of Immediate Risks

Deterioration in the Asset Quality of the Corporate Loan Portfolio and Interest Rate Risk

Signs of corporate loan deterioration in the Russian banking sector are observed differently depending on asset classification standards, but the overall indicators are on an upward trend. According to the Bank of Finland Institute for Emerging Economies (BOFIT), the share of corporate problem loans in a broad sense increased from 10% at the end of 2024 to 11% at the end of 2025 (RUB 10.4 trillion), and to 11.6% at the beginning of May 2026 (RUB 11.2 trillion), while Reuters and the European intelligence report estimated that the share of corporate loans whose recovery is uncertain or that are doubtful claims stood at about 10%. In response, Re:Russia and CMASF have presented the interpretation that Russia’s banking sector is formally already in a state of crisis, citing the fact that the share of problem assets has exceeded the 10% threshold.

By contrast, according to the Central Bank of Russia and Interfax data, the size of official corporate non-performing loans (Grades IV-V) increased slightly from RUB 3.4 trillion in October 2025 to RUB 3.5 trillion in April 2026, while its share within the overall portfolio was presented at 3.9% (about 4%); however, it should be noted that official non-performing loans of 4% and problem loans of 10-11.6% are based on different indicator definitions.

The monetary policy environment is also increasing the interest repayment burden on companies. According to BOFIT, with the share of floating-rate loans among corporate loans reaching about 65%, the average interest rate on short-term corporate loans exceeded 20% in the first half of 2025. Sberbank’s CFO stated that the impact of new sanctions would be limited because the market and customers have become accustomed to sanctions, but at the same time mentioned that the bank plans to lower its 2026 corporate loan growth forecast (previously 9-11%) due to deterioration in portfolio quality and an increase in restructuring requests.

Broadening of Distress in Household and Housing Finance Segments

Russia’s household debt-to-GDP ratio is about 21.4%, but distress indicators in subsegments of consumer credit stand out. According to the Central Bank of Russia, the NPL ratio for unsecured consumer loans is high at 13.1% (+0.2 percentage points compared with six months earlier), while the early delinquency rate for new unsecured loans (30 days or more after three months) eased somewhat from 2.8% to 2.0%. By contrast, according to Reuters and the European intelligence report, the retail finance NPL ratio at some large banks was presented as reaching up to 15% in 2025, and the number of personal bankruptcies increased by about 30% year-on-year, exceeding 500,000.

The scale of multiple borrowers also needs to be viewed from the perspective of its share of the population and international comparison, rather than simply from the perspective of year-on-year growth. The number of people in Russia with three or more loans, as presented by Reuters and the European intelligence report, is more than 13 million, which, based on Russia’s 2025 population of about 146 million, corresponds to about 8.9% of the total population. This is similar in scale to South Korea, where about 4.5 million multiple borrowers amount to about 8.7% of the 2025 population of about 51.68 million. However, South Korea’s multiple borrowers are usually defined as ‘borrowers from three or more financial institutions,’ whereas the Russian figure in Reuters’ report is presented as ‘holders of three or more loans,’ so the definitions are not completely identical. Therefore, even if it is not confirmed whether the number of multiple borrowers in Russia has increased year-on-year, in terms of its population share alone, it can be used as an indicator showing multiple-borrowing exposure at a level already similar to that of South Korea, a high-debt country.

Delinquency rates in the housing finance market are also rising. The overall housing loan NPL ratio was recorded at 1.7% at the end of 2025 according to BOFIT, and at 1.8% in April 2026 according to the Central Bank of Russia. In detail, the NPL 90+ ratio for single-family home construction mortgages was 4.6%, higher than the 0.9% ratio for apartment mortgages.

Insufficient Loan-Loss Provisions and Liquidity Structure

The Central Bank of Russia explains that vulnerabilities in the financial sector are not critical, citing the banking sector’s overall capital adequacy ratio of 13.9% and the liquidity coverage ratio (LCR) of systemically important banks at 117%. However, according to BOFIT’s analysis, the provisioning coverage for corporate problem loans is only 54%, and the capital ratios of five major banks were pointed out as being below 11.5%. In addition, as economic actors’ preference for cash has strengthened, cash holdings outside banks have increased; according to Reuters reporting citing Central Bank of Russia data, cash holdings outside banks exceeded RUB 19 trillion (about USD 243 billion), recording a year-on-year increase of more than 17%.

3. Geopolitical Interests and Outlook

The Intensification of Western Regulatory Pressure and the Blocking of Financial Networks

According to the European Commission, the EU is pursuing a ‘21st sanctions package against Russia’ that targets the financial, cryptocurrency, energy, and trade sectors as core areas, with the goal of adopting it by July 15, 2026. In particular, the package is under discussion to add about 90 Russian banks to the sanctions list. In this regard, Reuters reported that the measure is targeting a significant number of Russian financial institutions with international connections, and projected that if finally adopted, the total number of sanctioned Russian banks would exceed 100.

This can be seen as a measure that, in addition to direct sanctions against domestic Russian financial institutions, also targets third-country financial, cryptocurrency, and energy transaction channels that could be used for sanctions evasion. In the 21st sanctions package, the European Commission presented the expansion of transaction bans on 31 Russian banks, together with the addition of 20 third-country banks, cryptocurrency companies and platforms, and oil traders that service sanctioned Russian entities or are involved in sanctions evasion. It also explained that it would introduce for the first time the possibility of a complete ban on third-country crypto-asset services, while Reuters also reported that the package simultaneously targets Russian banks, cryptocurrency networks, oil traders, and refineries. As a result, this shows the West’s multi-pronged pressure stance, which encompasses third-country banks and cryptocurrency platforms, as well as oil traders, as sanctions targets.

Comparative Analysis Against Global Prudential Standards

Even taking into account differences in how each country defines its indicators, the figures related to distress in Russia’s banking sector are high compared with major comparator countries. Looking at non-performing loans (NPLs) or similar indicators in major countries, the EU/EEA stands at 1.8% (Stage 2 loans 9.3%), the United States at 1.53% (PDNA), Japan at 1.0%, and South Korea at 0.60% (corporate loans 0.74%).

By comparison, Russia’s corporate problem loan ratio (11.6%) and unsecured consumer loan NPL ratio (13.1%) show a substantial gap. In buffer indicators as well, compared with the United States (coverage of non-performing claims at 166.8%) and South Korea (loan-loss reserve ratio at 150.4%), Russia’s problem loan provisioning coverage (54%) is low, creating unfavorable conditions for hedging against the risk of loss occurrence in advance.

Overall Outlook and Conclusion

Russian financial authorities and some large banks claim system stability on the basis of sanctions learning effects and capital buffers. However, as internal indicators simultaneously show an increase in the share of problem loans, the level of consumer loan NPLs, the scale of personal bankruptcies, and the increase in cash holdings outside banks, it is being observed that the side effects of wartime fiscal spending and the expansion of policy finance are accumulating on bank balance sheets and in the household credit sector, and that this burden is intensifying.

In particular, considering that the IMF and ESRB emphasize resilience management, including checks on financial institutions’ capital, liquidity buffers, foreign-currency funding conditions, access to market-based funding, and counterparty risk exposure, in a phase of expanding geopolitical risk, this issue needs to be treated as a complex financial risk that combines sanctions, payment networks, sanctions circumvention finance, and energy transaction networks, in addition to Russia’s internal distress problem. In addition, as the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) virtual asset sanctions compliance guidance and recent studies on blockchain-based sanctions evasion show, cryptocurrency platforms and emerging payment instruments can be used as evasion channels even after sanctions enforcement.

Therefore, alongside whether the EU’s 21st sanctions package is finally adopted, it is necessary to continuously track the subsequent blocking effects on third-country financial institutions, cryptocurrency platforms, oil traders, and Russian internationally connected banking networks. It is also judged necessary to maintain an expanded sanctions exposure review system that includes not only direct Russia-related risk exposure, but also third-country routed payments, energy transaction counterparties, virtual asset-based evasion payments, foreign-currency funding, and counterparty risk.
