Summary of the Evaluation of the Effects of Financial Regulatory Reforms on SME Financing

Core Content

This document evaluates the impact of financial regulatory reforms, particularly Basel III, on the financing of small and medium-sized enterprises (SMEs). The analysis is conducted through a combination of cross-country and within-country studies, using a variety of datasets to provide a comprehensive understanding of how these reforms affect SME access to credit, lending behavior, and financial terms.

The evaluation is part of the G20's broader effort to assess the resilience of the global financial system post-financial crisis. The focus is on whether the reforms have had material and persistent negative effects on SME financing, and if so, to what extent.

Main Questions and Objectives

The study addresses four key questions:

1. Did the SME lending of the most affected banks slow in the aftermath of the Basel III reforms?
2. Did the reforms have a stronger effect on the financing of SMEs relative to that of larger, non-financial companies?
3. Did the terms of SME financing—such as maturity, collateral requirements, and costs—tighten after the reforms were implemented?
4. Did the allocation of SME credit change across banks or firms after the reforms came into effect?

These questions guide the empirical analysis, which is conducted using 15 different datasets, each offering a unique perspective on SME financing.

Datasets and Analytical Approaches

The evaluation uses two main perspectives:

• Bird's Eye View: Aggregates data across multiple countries to identify broad trends and effects.
• Grassroots Perspective: Conducts detailed, jurisdiction-specific analyses using granular data.

Key Datasets

The datasets vary in coverage and granularity, which influences the analytical approach and the ability to isolate reform effects.

Basel III Reforms and Implementation Stages

The evaluation focuses on the Risk-Based Capital (RBC) reform, as well as other Basel III reforms such as:

• Liquidity Coverage Ratio (LCR)
• Leverage Ratio (LR)
• G-SIB/D-SIB framework
• Net Stable Funding Ratio (NSFR)

The RBC reform is central to the analysis, as it was the first to be implemented and had a significant impact on bank behavior. The implementation stages considered are:

• Stage 2 (Draft regulation published)
• Stage 3 (Final rule published)

These stages are used to capture both temporary and persistent effects of the reforms on SME financing.

Empirical Specification and Challenges

To isolate the impact of reforms, the evaluation employs econometric identification strategies, including:

• Fixed effects at the country, bank, and firm levels
• Control variables for macroeconomic and financial conditions
• On/off dummy variables to capture the temporary impact of reforms
• Persistent dummy variables to capture the long-term impact

However, the study faces several challenges, including:

• The lack of a natural control group of banks unaffected by the reforms
• The difficulty in separating supply and demand effects
• The potential confounding of reform effects with other macroeconomic factors

These challenges are addressed by comparing more affected banks with less affected banks, based on their pre-reform exposure to the regulations.

Key Findings

• No "one-size-fits-all" pattern was observed: the effects of the reforms vary across jurisdictions.
• Temporary slowdown in SME lending growth was noted for the most affected banks (Q1).
• Reforms had a stronger effect on SMEs compared to larger firms (Q2), particularly in terms of credit allocation.
• Tighter credit conditions were observed in some jurisdictions (Q3), with more affected banks requiring more collateral and charging higher interest rates.
• Reallocation of credit towards more creditworthy SMEs was evident in several analyses (Q4), with better-capitalised and more profitable firms benefiting more from the reforms.

Conclusion

The overall conclusion is that the reforms do not appear to have had material and persistent negative effects on SME financing in general. While there were some temporary impacts, especially on the most affected banks, the effects were not uniform across jurisdictions and generally found to be short-lived. This conclusion is consistent with existing literature and stakeholder feedback, which suggest that SME financing is influenced more by market conditions and firm-specific factors than by financial regulation alone.

The study highlights the importance of granular data and robust econometric methods in understanding the nuanced effects of financial regulatory reforms on SME financing.
