Summary of the Financial Sector Assessment Program Stress Testing in the Republic of Moldova (June 2014)

Core Content

The Financial Sector Assessment Program (FSAP) stress testing in the Republic of Moldova, conducted in February 2014 by an IMF-World Bank joint mission, aimed to evaluate the resilience of the banking system to major risk sources. The assessment included solvency and liquidity stress tests, as well as sensitivity analysis, to understand potential vulnerabilities and their implications for financial stability.

Main Points

Banking System Overview

• The banking sector in Moldova is primarily domestically oriented, with traditional lending as its main activity.
• As of 2013, there were 14 licensed banks, with total assets close to MDL 70bn, or 72% of GDP.
• The largest 5 banks accounted for almost 70% of the system's assets.
• Loans represent 56% of total assets, mostly directed to the corporate sector.
• A significant share of assets and liabilities are denominated in foreign currency (MDL, USD, EUR).

Stress Test Coverage

• All 14 banks were included in the stress testing process.
• Top-down stress tests were conducted by the FSAP team and the National Bank of Moldova (NBM), using supervisory data.
• Bottom-up stress tests were carried out by individual banks using their internal models and the macroeconomic scenarios provided by the FSAP team.
• Liquidity stress tests were also conducted, with an emphasis on both local and foreign currency liquidity.

Macroeconomic Scenarios

• Four scenarios were considered: a baseline and three adverse scenarios.
• Adverse Scenario 1: A slowdown in major emerging markets and lower oil prices lead to a moderate slowdown in the Russian economy, affecting Moldova's trade, remittances, and capital inflows.
• Adverse Scenario 2: A severe global shock due to the unwinding of unconventional monetary policies leads to increased sovereign spreads and economic stress, with significant negative impacts on Moldova's economy.
• Adverse Scenario 3: A severe drought in Moldova combined with export restrictions to Russia affects agricultural output and overall GDP growth, leading to currency depreciation and interest rate increases.

Key Findings

Solvency Stress Tests

• Credit Risk: The most significant risk factor, with potential losses on the loan book ranging from MDL 1.7bn (1.7% of GDP) to MDL 5.0bn (5.1% of GDP).
• Issuer Default Risk: Losses were estimated based on the probability of default (PD), loss given default (LGD), and exposure at default (EAD) for debt instruments.
• Equity Investment Risk: Potential losses from equity investments were considered, though the focus was more on credit and market risks.
• Concentration Risk: A few banks have high concentration risks, particularly with large single-name exposures.
• Interbank Contagion Risk: While domestic interbank contagion risk is limited, some banks have significant foreign interbank exposures that could lead to insolvency if not managed properly.

Liquidity Stress Tests

• The banking system as a whole has sufficient liquidity, with the system-wide liquidity coverage ratio (LCR) exceeding 100%.
• FX liquidity was also assessed, with potential shortfalls estimated at MDL 1.2bn (USD 89mn), representing 3% of central bank FX reserves.
• A few banks rely on large-scale cross-border interbank placements for liquidity, raising concerns about the genuine liquidity of these positions.
• Overall potential liquidity shortfall is estimated at MDL 1.6bn (1.6% of GDP).

Methodology and Assumptions

• Stress tests were conducted under the constant balance sheet assumption, meaning no changes in asset or liability composition were considered.
• The logit transformation was used to model the NPL ratio as a function of macroeconomic variables.
• The estimation model (Equation [2]) was used to quantify the relationship between macroeconomic variables and NPLs, with results summarized in Table 2.
• The sensitivity analysis was used to assess the impact of macroeconomic shocks on the banking system.
• Behavioral assumptions included maintaining constant risk-weighted assets (RWAs), unchanged balance sheet composition, and excluding income items such as net fees and operating costs.

Conclusions

• The banking system is generally well-capitalized and liquid.
• However, significant vulnerabilities exist in specific segments, particularly related to concentration risk, foreign exposure, and the quality of liquid assets.
• The three most vulnerable banks are highly interconnected but have limited direct linkages with other domestic banks.
• Non-transparent relationships and indirect contagion risks (e.g., reputational risk) could still pose a threat to the overall stability of the system, even if not directly assessed in the stress tests.

Key Information

• Top-down and bottom-up stress tests were conducted, with some discrepancies observed in credit risk loss estimates.
• The baseline scenario was based on IMF projections, while the three adverse scenarios tested the system's resilience to various shocks.
• Credit risk was the most important risk factor, with potential losses on the loan book being the largest.
• Market risk was assessed through interest rate and exchange rate risks, with relatively small impacts due to the limited use of trading instruments.
• Liquidity risk was found to be manageable overall, though some banks may face challenges.
• The LCR was calculated using Basel III-type proxies, with the system-wide ratio exceeding 100%.
• FX liquidity was also assessed, with potential shortfalls being a small portion of central bank reserves.

Additional Notes

• The stress tests were based on instantaneous shocks, not multi-year projections.
• The logit transformation was used to ensure NPL ratios remained between 0 and 1.
• The NPL-ratio was found to be sensitive to real GDP growth and exchange rate changes.
• Valuation changes on fixed income instruments were treated separately and are not included in the solvency stress test results.
• The impact of interest rate changes was assessed using time-to-repricing buckets, with the gap between assets and liabilities being a key factor in estimating potential losses.
