What Is Advanced Leverage Ratio?
The Advanced Leverage Ratio refers to stricter, non-risk-weighted capital requirements imposed on the largest and most interconnected financial institutions, often known as Global Systemically Important Banks (G-SIBs). It falls under the umbrella of banking supervision and financial regulation, serving as a crucial backstop to traditional risk-weighted assets calculations. Unlike risk-based measures that assign different capital charges based on the perceived riskiness of assets, the Advanced Leverage Ratio requires banks to hold a minimum amount of Tier 1 capital against a broad measure of total exposures, regardless of their risk profile. This framework aims to limit excessive on- and off-balance sheet exposures and enhance the overall financial stability of the banking system.
History and Origin
The concept of a leverage ratio gained renewed prominence following the 2008 global financial crisis. Prior to the crisis, regulatory focus leaned heavily on risk-weighted capital ratios, which proved insufficient in capturing certain risks and preventing the build-up of excessive leverage. In response, the Basel Committee on Banking Supervision (BCBS) introduced the Basel III framework in 2010, which included a non-risk-based leverage ratio as a fundamental component. This ratio was designed to serve as a simple, transparent backstop to the more complex risk-based capital requirements.
For the largest, most systemically important banks, an enhanced version of this leverage ratio was subsequently developed. In the United States, this is known as the Enhanced Supplementary Leverage Ratio (eSLR). The Federal Reserve, along with other U.S. regulatory bodies, implemented these enhanced standards to apply specifically to U.S. bank holding companies with over $700 billion in consolidated assets or more than $10 trillion in assets under custody, as well as their subsidiary insured depository institutions23. These more stringent requirements were designed to mitigate the systemic risk posed by these institutions, ensuring they held a higher buffer of capital against potential losses21, 22.
Key Takeaways
- The Advanced Leverage Ratio is a non-risk-weighted capital requirement designed for large, systemically important financial institutions.
- It serves as a backstop to risk-based capital calculations, ensuring banks maintain a baseline level of capital regardless of asset risk.
- The ratio aims to prevent the build-up of excessive leverage and promote financial stability.
- For U.S. Global Systemically Important Banks (G-SIBs), the Advanced Leverage Ratio is implemented as the Enhanced Supplementary Leverage Ratio (eSLR).
- Compliance with the Advanced Leverage Ratio influences a bank's ability to engage in certain market activities, such as facilitating trading in U.S. Treasury markets.
Formula and Calculation
The Advanced Leverage Ratio, often expressed as the Enhanced Supplementary Leverage Ratio (eSLR) for G-SIBs, is calculated by dividing a bank's Tier 1 capital by its total leverage exposure.
Where:
- Tier 1 Capital: This includes Common Equity Tier 1 (CET1) and other qualifying Tier 1 instruments. It represents the highest quality of capital that can absorb losses without a bank being required to cease trading20.
- Total Leverage Exposure: This denominator is a comprehensive measure that includes all on-balance sheet assets, a measure of derivatives exposures, and securities financing transactions (SFTs), as well as certain off-balance sheet exposures. This broad scope is intended to prevent regulatory arbitrage by ensuring all significant exposures are captured18, 19.
The ratio is expressed as a percentage. For instance, if a bank has $100 billion in Tier 1 capital and $2 trillion in total leverage exposure, its Advanced Leverage Ratio would be 5%.
Interpreting the Advanced Leverage Ratio
Interpreting the Advanced Leverage Ratio primarily involves assessing a bank's resilience against unexpected losses, independent of the risk weights applied to its assets. A higher Advanced Leverage Ratio generally indicates a stronger capital position relative to its total exposures, suggesting a greater capacity to absorb losses. Regulators set minimum thresholds for this ratio to ensure banks maintain adequate capital buffers. For U.S. Global Systemically Important Banks, the Enhanced Supplementary Leverage Ratio (eSLR) typically requires a higher percentage than the basic Basel III leverage ratio, reflecting their systemic importance and the potential for their failure to trigger broader financial distress16, 17.
While a strong Advanced Leverage Ratio is desirable, an excessively high requirement can sometimes disincentivize banks from holding low-risk, low-return assets like U.S. Treasury securities, as these still consume capital under the ratio despite their minimal credit risk. This is a point of ongoing debate in regulatory circles regarding the precise calibration of the ratio14, 15. The ratio is therefore viewed as a foundational measure, complementing rather than replacing, more granular risk-based capital assessments.
Hypothetical Example
Consider "DiversiBank," a large, internationally active financial institution designated as a Global Systemically Important Bank. Regulators require DiversiBank to maintain an Advanced Leverage Ratio (e.g., eSLR) of at least 5%.
DiversiBank's financial data shows:
- Tier 1 Capital: $75 billion
- On-balance sheet assets: $1.2 trillion
- Derivatives exposures (add-on): $150 billion
- Securities financing transactions (add-on): $100 billion
- Other off-balance sheet items (credit conversion factor applied): $50 billion
To calculate DiversiBank's total leverage exposure:
Total Leverage Exposure = On-balance sheet assets + Derivatives exposures + Securities financing transactions + Other off-balance sheet items
Total Leverage Exposure = $1,200 billion + $150 billion + $100 billion + $50 billion = $1,500 billion (or $1.5 trillion)
Now, calculate DiversiBank's Advanced Leverage Ratio:
In this scenario, DiversiBank's Advanced Leverage Ratio is 5%, which meets the hypothetical regulatory requirement. This demonstrates that for every dollar of total exposure, DiversiBank holds 5 cents of high-quality Tier 1 capital.
Practical Applications
The Advanced Leverage Ratio has several practical applications, primarily within the realm of banking and financial regulation. Its main purpose is to strengthen the resilience of individual banks and, by extension, the entire financial system.
One key application is in regulatory compliance, particularly for Global Systemically Important Banks (G-SIBs). These institutions face higher Advanced Leverage Ratio requirements as part of global standards, such as those under Basel III13. Regulators use this ratio as a non-risk-based backstop, ensuring that even if complex risk-weighted assets models fail to capture certain risks, a foundational level of capital is always maintained. This regulatory oversight helps to prevent the build-up of excessive leverage across the financial system12.
Furthermore, the Advanced Leverage Ratio can influence a bank's business strategy and its participation in certain financial markets. For example, large U.S. bank holding company structures have sometimes found that stringent Advanced Leverage Ratio requirements can act as a constraint on their ability to facilitate trading in low-risk assets like U.S. Treasury securities, impacting monetary policy transmission10, 11. Recent proposals by the Federal Reserve highlight ongoing efforts to recalibrate these standards to ensure the Advanced Leverage Ratio functions as an effective backstop without unduly hindering banks' roles as market intermediaries9.
Limitations and Criticisms
While the Advanced Leverage Ratio offers a straightforward measure of a bank's capital strength, it is not without limitations and has faced criticism. One primary critique is its "risk-insensitivity." Unlike risk-weighted assets calculations, the Advanced Leverage Ratio treats all assets equally, regardless of their inherent riskiness8. This means a bank holding very safe assets like government bonds is subject to the same capital charge for those assets as a bank holding much riskier loans. Critics argue this can create perverse incentives, potentially encouraging banks to shift towards higher-risk, higher-yielding assets to optimize their capital, as long as they stay within the leverage ratio's constraints, because those assets would offer a better return for the same leverage ratio capital charge6, 7.
Another concern relates to its potential impact on market liquidity. During periods of market stress, some argue that strict Advanced Leverage Ratio requirements can discourage large banks from acting as intermediaries in critical markets, such as the U.S. Treasury market, by making it less capital-efficient to hold low-risk assets5. This was particularly noted during the COVID-19 pandemic, leading to temporary adjustments to the ratio's calculation. The debate continues regarding the optimal calibration of the Advanced Leverage Ratio to ensure it serves as an effective backstop without unintentionally hindering beneficial market activities or distorting bank portfolios4. Furthermore, the complexity of defining "total leverage exposure," particularly for off-balance sheet exposures, means the ratio may not be as "simple" as its advocates often claim3.
Advanced Leverage Ratio vs. Supplementary Leverage Ratio
The terms "Advanced Leverage Ratio" and "Supplementary Leverage Ratio" (SLR) are closely related within the context of banking regulation, especially in the United States. The Supplementary Leverage Ratio (SLR) itself is the core non-risk-weighted measure introduced under the Basel III framework, calculated as Tier 1 capital divided by total leverage exposure2.
The Advanced Leverage Ratio, as understood in practice, typically refers to the Enhanced Supplementary Leverage Ratio (eSLR) applied to Global Systemically Important Banks (G-SIBs) in the U.S. While the basic SLR has a minimum requirement (e.g., 3%), the eSLR imposes higher capital requirements specifically on these large, complex institutions. For instance, U.S. G-SIBs have historically faced requirements of 5% at the holding company level and 6% at the depository level for their eSLR, representing a significant uplift over the baseline SLR1. The distinction lies in the stringency and specific application to the most systemically important entities, aiming to provide an additional layer of capital protection beyond what the standard SLR might require for other banks. Therefore, the Advanced Leverage Ratio is essentially a more stringent, enhanced form of the Supplementary Leverage Ratio tailored for institutions posing greater systemic risk.
FAQs
What is the primary purpose of the Advanced Leverage Ratio?
The primary purpose of the Advanced Leverage Ratio is to serve as a non-risk-based backstop to traditional risk-weighted assets requirements, preventing the build-up of excessive leverage, particularly in large, interconnected financial institutions. It aims to ensure a foundational level of Tier 1 capital is maintained regardless of the perceived riskiness of assets.
How does it differ from risk-weighted capital ratios?
Unlike risk-weighted capital ratios, which assign different capital charges based on the estimated risk of various assets, the Advanced Leverage Ratio treats all assets and exposures equally. This simplicity is its strength as a backstop, but also a point of criticism regarding its risk-insensitivity.
Which institutions are typically subject to Advanced Leverage Ratio requirements?
Typically, only the largest and most complex financial institutions, often designated as Global Systemically Important Banks (G-SIBs), are subject to Advanced Leverage Ratio requirements like the Enhanced Supplementary Leverage Ratio (eSLR).
Can the Advanced Leverage Ratio impact a bank's operations?
Yes, the Advanced Leverage Ratio can significantly impact a bank's operations. High requirements may influence a bank's balance sheet composition, affecting its willingness to hold certain low-risk assets and its capacity to engage in market-making activities, particularly for low-return, high-volume transactions like those in the U.S. Treasury market.
What is the role of the Basel Committee on Banking Supervision (BCBS) in this ratio?
The Basel Committee on Banking Supervision (BCBS) developed the international standards for the leverage ratio under Basel III. Their guidelines provide the framework upon which national regulators, like the Federal Reserve, implement specific Advanced Leverage Ratio requirements for institutions within their jurisdictions.
