SMEs as the Backbone of the Economy and the Structural Constraints of Access to Finance

SMEs form the backbone of Türkiye’s economy, accounting for over 99% of all enterprises and playing a critical role in employment, exports, and production. (Source: OECD – Financing SMEs and Entrepreneurs 2026)

Despite this strong foundation, a structural constraint continues to limit growth: access to finance.

Recent data indicates that SME lending in Türkiye has exceeded TRY 4.9 trillion, reflecting both strong demand and significant policy support. (Source: OECD, 2026)

However, despite this expansion, access to finance challenges persist and have become increasingly concentrated within specific segments of the market.

The “Missing Middle”: A Structural Gap in the Financial System

Despite approximately €104 billion in guarantees provided through the Credit Guarantee Fund (KGF), of which around 77% has been allocated to SMEs, a significant segment of businesses remains underserved. (Source: EBRD – SME Sector Assessment Türkiye)

This situation reflects a structural gap between the financial system and the real economy. Commonly referred to as the “missing middle,” this segment represents businesses that are too large for micro-scale solutions but insufficiently served by conventional banking structures.

This challenge is also observed at a global level. The global SME financing gap is estimated to exceed USD 5.7 trillion. (Source: IFC / SME Finance Forum)

Participation Finance: A Model Aligned with the Real Economy

Participation (Islamic) banking is inherently aligned with SME financing through its asset-backed structure, risk-sharing principles, and direct linkage to the real economy.

This alignment is also reflected in sectoral data:

  • SMEs account for approximately 34% of participation bank portfolios
  • Compared to approximately 25% across the overall banking system (Source: TKBB)

However, participation banking represents only around 9.2% of total banking assets in Türkiye, as of end-2025. (approximately TRY 4.3 trillion). (Source: BDDK, Monthly Statistics)

This disparity highlights a significant untapped potential within the system.

The Untapped Opportunity: Scaling Participation Finance

Participation banks currently provide approximately TRY 894 billion in SME financing, corresponding to roughly a 12% market share. (Source: TKBB)

If participation finance expands its market share to the 15–20% range, the system could unlock an additional TRY 700 billion to TRY 1 trillion in SME financing capacity.

This estimate is based on OECD SME lending data and TKBB participation banking market share metrics.

Why This Matters for Global Investors

Türkiye presents a compelling opportunity for international investors, combining:

  • Strong underlying demand driven by SMEs,
  • A functioning and established banking infrastructure,
  • Active policy and development finance institution support.

This is evidenced by:

  • Up to €1.5 billion mobilized by the World Bank for SME financing in Türkiye,
  • Approximately USD 6.3 billion in financing commitments by the Islamic Development Bank (Source: Reuters / World Bank & IsDB).

However, despite this potential, investors face key structural barriers:

  • Limited local origination networks,
  • Regulatory and structuring complexities,
  • Lack of on-the-ground participation finance execution capabilities.

These barriers create a gap between capital availability and effective deployment.

From Financing Gap to Strategic Entry Point

Türkiye’s SME financing gap should not be viewed as a limitation, but rather as a strategic entry point for participation finance.

The key challenge is not merely the availability of capital, but the ability to structure, deploy, and manage that capital effectively within local market dynamics.

Participation finance offers a scalable and structurally aligned solution. However, unlocking this potential requires:

  • Strong local market knowledge,
  • Robust structuring capabilities,
  • Effective execution capacity.

Ultimately, success in this market will not be defined by capital alone, but by the ability to deploy it intelligently, locally, and in a participation finance manner.
