Summary of "Changes in Bank Financing Patterns" (April 2012)

Core Content

This report by the European Central Bank (ECB) examines the changes in bank funding patterns in the euro area from 1999 to 2011, focusing on five main categories of bank liabilities: interbank funding, customer deposits, debt securities, central bank funding, and capital. The analysis is based on statistics from monetary financial institutions (MFIs) and identifies a significant break in the trend of most indicators in the third quarter of 2008, which coincided with the onset of the global financial crisis.

Main Findings

Interbank Funding

• Interbank liabilities as a proportion of total assets fell substantially after the third quarter of 2008.
• Domestic bank liabilities increased as a share of total interbank liabilities in the largest euro area economies.
• Unsecured money market activity declined significantly, while secured funding through central counterparties (CCPs) increased.
• Wholesale funding costs rose, with wider spreads between unsecured and secured transactions compared to pre-crisis levels.
• Lending activity shifted towards shorter maturities, and there was a growing "home bias" in interbank lending due to liquidity constraints and solvency concerns.

Customer Deposits

• Deposit liabilities as a share of total assets started increasing after 2008, reversing a previous decline.
• Loan-to-deposit ratios decreased from their peak in 2008, indicating a shift in funding sources.
• Retail deposits became more important and more expensive than corporate deposits due to increased competition.
• A shift towards longer maturity deposits was observed at both aggregate and national levels.

Debt Securities

• The ratio of debt securities to assets began declining in 2007, well before the crisis.
• Gross issuance of debt securities by euro area banks halved from its 2006 peak by 2011.
• Securitisation also declined sharply after 2008.
• The average maturity of debt issued by banks increased from the third quarter of 2008.
• Funding costs through debt securities rose significantly, including for covered bonds.
• The composition of collateral changed, with a decline in unsecured bank bonds and an increase in non-marketable securities.

Central Bank Funding

• Central bank funding increased substantially due to constraints in accessing wholesale market funding.
• Non-standard Eurosystem refinancing measures were introduced, particularly for banks in countries under financial assistance or facing sovereign tensions.
• Collateral composition changed, reflecting market and regulatory pressures.

Capital and Bank Leverage

• The capital-to-assets ratio began increasing in early 2009, driven by both capital growth and asset contraction.
• Bank leverage remained relatively stable in the pre-crisis period, but changes in funding patterns affected balance sheet dynamics.

Financial Stability Considerations

The report highlights several implications of these changes for financial stability:

• Secured funding (collateralised) has become more important for both wholesale and central bank funding.
• Asset composition on banks' balance sheets has shifted, with a greater reliance on liquid assets.
• Collateralisation may impose limits on lending activity and balance sheet growth.
• Retail funding has become more competitive and more expensive.
• Central bank funding may not return to pre-crisis levels due to ongoing market and regulatory constraints.

Key Points and Main Viewpoints

• Trend break in funding patterns was identified in Q3 2008, supported by econometric analysis.
• Secured funding and central bank support became more prominent in the post-crisis period.
• Diversification of funding sources and increased liquidity buffers are part of the new regulatory environment (e.g., Basel III).
• Cross-border integration in the banking sector was reduced, with a rise in "home bias."
• Market liquidity and funding liquidity are distinct but related concepts, with the latter being more critical in the context of the financial crisis.

Methodology and Data

• The report uses MFI balance sheet statistics and interest rate data.
• Data sources include ECB, Dealoric, and Bloomberg.
• A centralised database was created for analysis, focusing on unconsolidated data.
• Indicators were built to capture trends in funding structure, maturity, and cost.
• Graphical analysis and statistical tests (Annex 1) were used to illustrate changes in funding patterns over time.

Conclusion

The report concludes that the financial crisis has led to durable changes in euro area bank funding patterns. These changes are expected to influence the future financial landscape and raise important financial stability considerations, including the role of secured funding, the impact of regulatory changes, and the long-term implications for bank balance sheets and sovereign debt markets.
