Fitch Scenario: Risks to Turkish Banking Seen Emerging from Real Sector Stress

ekonomi stres testi

A new stress test by Fitch Ratings suggests that while Türkiye’s banking system remains broadly resilient, vulnerabilities could surface under severe scenarios combining sharp currency depreciation and a spike in non-performing loans (NPLs). The report highlights that the main source of systemic risk lies not within banks themselves, but in the real sector—particularly highly leveraged companies exposed to foreign currency risk.

Fitch Stress Test: Two Key Scenarios

Fitch assessed nine major Turkish banks under two combined risk scenarios involving exchange rate shocks and credit deterioration.

1. Moderate Shock Scenario (USD/TRY ≈ 60)

  • Most banks maintain capital adequacy
  • Profitability declines but remains manageable
  • NPL ratios rise, though at controllable levels

This scenario assumes a gradual depreciation of the Turkish lira alongside the continuation of current macroeconomic policies.

2. Severe Shock Scenario (USD/TRY ≈ 75)

  • Currency shock coincides with deterioration in asset quality
  • At least one bank falls below core capital adequacy thresholds
  • Sector-wide capital buffers begin to erode
  • Sharp increase in non-performing loans

This scenario reflects a broader crisis in which corporate repayment capacity weakens significantly, amplifying stress across the financial system.

Dual Pressure Channels: FX and Credit Risk

Fitch identifies two primary transmission channels affecting banks:

1. Currency Risk (FX Shock)

  • Companies with open foreign currency positions face mounting pressure
  • Lira depreciation reduces debt-servicing capacity
  • Banks’ indirect credit exposure increases

2. Credit Quality Deterioration

  • Rising NPL ratios
  • Higher provisioning costs
  • Pressure on profitability and capital adequacy

How Resilient Is the Banking System?

Fitch’s findings suggest that Türkiye’s banking sector is not inherently fragile, but is approaching critical thresholds under adverse conditions.

Strengths

  • Strengthened capital buffers in recent years
  • Tightened regulatory framework led by the Banking Regulation and Supervision Agency
  • Relatively disciplined liquidity management

Weaknesses

  • High corporate sector leverage
  • Currency mismatch between revenues and liabilities
  • Strained cash flows in a high-interest-rate environment

Critical Trigger: FX Shock Plus NPL Surge

Fitch emphasizes that a currency shock alone is unlikely to destabilize the system. However, the combination of:

  • Sharp lira depreciation
  • Rising loan defaults

could create systemic risk.

The transmission mechanism is clear:

  1. Currency depreciation weakens corporate balance sheets
  2. Companies struggle to service debt
  3. Loan defaults increase
  4. Bank capital erodes

2026 Outlook: Two Diverging Paths

Base Case Scenario

  • Gradual currency depreciation
  • Limited increase in NPLs
  • Banks absorb profitability pressures without systemic stress

Stress Scenario

  • Abrupt currency shock
  • Widespread deterioration in the real sector
  • Potential need for capital injections

Where the Real Risk Lies

The most critical takeaway from the report is that any potential banking crisis in Türkiye would originate outside the banking sector.

Fitch points to vulnerabilities concentrated in:

  • Manufacturing firms
  • SMEs
  • Companies with significant FX-denominated debt

In this framework, the real sector acts as the primary transmission channel of risk into the banking system.

Conclusion: System Resilient, but Under Strain

Fitch’s analysis paints a nuanced picture of Türkiye’s banking sector:

  • Short term: Resilient and well-capitalized
  • Medium term: Accumulating vulnerabilities

A USD/TRY scenario approaching 75 would signal not just banking stress, but a broader macroeconomic tipping point.

The report underscores that while banks remain stable for now, the sustainability of that stability depends heavily on the health of the real economy.
