Backdated net stable funding ratio

What Is Net Stable Funding Ratio?

The Net Stable Funding Ratio (NSFR) is a crucial regulatory metric within the realm of Bank Regulation and Liquidity Management that requires banks to maintain a minimum amount of stable funding to support their assets and off-balance sheet activities over a one-year time horizon. This standard is designed to reduce the likelihood that disruptions to a banking organization's regular sources of funding will compromise its liquidity position and contribute to instability in the financial system. The NSFR promotes effective asset-liability management by encouraging banks to fund their long-term assets with more stable and reliable funding sources, thereby limiting excessive maturity transformation.

History and Origin

The genesis of the Net Stable Funding Ratio can be traced back to the 2007–2008 global financial crisis. During this period, many banks, despite meeting existing capital requirements, faced severe difficulties due to their over-reliance on short-term, less-stable wholesale funding from interbank lending markets. This vulnerability to funding shocks highlighted significant shortcomings in the management of market liquidity and funding risk within the banking sector, leading to widespread systemic risk.

¹⁷In response, the Basel Committee on Banking Supervision (BCBS) developed Basel III, a comprehensive set of international regulatory reforms aimed at strengthening global capital and liquidity regulations. The NSFR was initially proposed in 2010 and finalized by the BCBS on October 31, 2014, as a key component of these reforms., ¹⁶The rule became a minimum standard by January 1, 2018, globally. I¹⁵n the United States, federal bank regulatory agencies, including the Federal Reserve Board, the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC), issued a final rule on October 20, 2020, to implement the NSFR for large banking organizations, effective July 1, 2021.,

13## Key Takeaways

• The Net Stable Funding Ratio (NSFR) is a liquidity standard designed to ensure banks have sufficient stable funding over a one-year horizon.
• It is a core component of the Basel III international regulatory framework.
• The NSFR aims to reduce reliance on short-term, unstable funding and promote a more sustainable funding structure.
• A higher NSFR generally indicates a more stable funding profile for a bank.
• The ratio measures available stable funding against required stable funding.

Formula and Calculation

The Net Stable Funding Ratio is calculated as the ratio of a bank's Available Stable Funding (ASF) to its Required Stable Funding (RSF). The regulatory minimum for this ratio is 1.0, or 100%, indicating that a bank must have at least as much stable funding as it requires.

¹²The formula for the Net Stable Funding Ratio is:

$\text{NSFR} = \frac{\text{Available Stable Funding (ASF)}}{\text{Required Stable Funding (RSF)}} \ge 1.0$

Where:

• Available Stable Funding (ASF) refers to the portion of a bank's capital and liabilities that are expected to be reliable over a one-year time horizon. Different categories of funding are assigned specific "ASF factors" based on their perceived stability. For example, regulatory capital elements often receive a 100% ASF factor, while certain types of retail deposits or long-term wholesale funding may receive high factors.,
  ¹¹*¹⁰ Required Stable Funding (RSF) represents the amount of stable funding a bank needs to hold, determined by the liquidity characteristics and residual maturities of its assets, derivatives, and off-balance sheet activities. Assets that are less liquid or have longer maturities require higher RSF factors.

⁹The precise calculation involves summing the weighted amounts of various balance sheet items.

Interpreting the Net Stable Funding Ratio

Interpreting the Net Stable Funding Ratio involves assessing a bank's structural liquidity over a longer-term horizon. A ratio of 100% or more signifies that a bank maintains enough stable funding to cover its less liquid assets and activities for at least one year. This threshold indicates compliance with regulatory standards and a robust funding profile.

A ratio significantly above 100% suggests that a bank has a strong and conservative funding structure, potentially relying heavily on long-term liabilities and equity. Conversely, a ratio approaching or falling below 100% could signal potential vulnerabilities. For instance, if a bank has a large proportion of illiquid assets funded by short-term or less stable sources, its NSFR would be lower, indicating an increased exposure to funding risk. Regulators use the NSFR to ensure banks can withstand extended periods of market stress without compromising their ability to continue lending and providing financial services.

⁸## Hypothetical Example

Consider a hypothetical bank, "DiversiBank," at the end of a fiscal year. DiversiBank needs to calculate its Net Stable Funding Ratio to ensure compliance with prudential regulation.

Available Stable Funding (ASF):

• Shareholders' Equity: $200 million (ASF factor: 100%)

• Long-term Debt (maturity > 1 year): $150 million (ASF factor: 100%)

• Stable Retail Deposits (non-maturity or term > 1 year): $300 million (ASF factor: 90%)

• Less Stable Retail Deposits (maturity < 1 year): $100 million (ASF factor: 50%)

• Short-term Wholesale Funding (maturity < 6 months): $50 million (ASF factor: 0%)

• Calculated ASF = ($200M * 1.00) + ($150M * 1.00) + ($300M * 0.90) + ($100M * 0.50) + ($50M * 0.00)

• Calculated ASF = $200M + $150M + $270M + $50M + $0M = $670 million

Required Stable Funding (RSF):

• Liquid Assets (e.g., cash, high-quality government bonds): $100 million (RSF factor: 0%)

• Loans to Non-Financial Corporates (maturity > 1 year): $400 million (RSF factor: 85%)

• Mortgage Loans (maturity > 1 year): $250 million (RSF factor: 65%)

• Residential Mortgages (maturity > 1 year): $200 million (RSF factor: 50%)

• Securities financing transactions (secured by level 1 assets, maturity < 6 months): $50 million (RSF factor: 10%)

• Calculated RSF = ($100M * 0.00) + ($400M * 0.85) + ($250M * 0.65) + ($200M * 0.50) + ($50M * 0.10)

• Calculated RSF = $0M + $340M + $162.5M + $100M + $5M = $607.5 million

Net Stable Funding Ratio (NSFR):

• NSFR = $670 million / $607.5 million ≈ 1.103 or 110.3%

In this example, DiversiBank's NSFR of 110.3% exceeds the minimum 100% requirement, indicating a sound and compliant funding structure.

Practical Applications

The Net Stable Funding Ratio (NSFR) serves as a critical tool in several areas of finance and regulation:

• Bank Supervision and Regulation: Regulatory bodies globally, following the Basel III framework, mandate the NSFR for large, internationally active banks to ensure their long-term financial stability. It ⁷complements the Liquidity Coverage Ratio (LCR), which addresses short-term liquidity risks, by focusing on a longer, more normalized time horizon for funding.
• ⁶ Risk Management: Banks utilize the NSFR internally to monitor and manage their structural liquidity risk. It helps them identify potential mismatches between the maturity profiles of their assets and liabilities, prompting adjustments to their funding strategies.
• Investor and Analyst Evaluation: Investors and financial analysts use a bank's disclosed NSFR to assess its funding strength and overall resilience. A healthy NSFR can be a positive indicator of a bank's ability to withstand adverse market conditions.
• Policy Making: The NSFR influences central bank and government policies related to credit availability and financial market functioning. By requiring stable funding for long-term assets, the NSFR impacts banks' incentives for long-term lending to businesses and households.
• Market Discipline: Public disclosure requirements for the NSFR, such as those implemented by various jurisdictions, promote market discipline by allowing stakeholders to scrutinize a bank's funding profile.

##⁵ Limitations and Criticisms

While the Net Stable Funding Ratio is a key component of strengthening bank resilience, it faces certain limitations and criticisms:

One primary concern is its potential impact on banks' traditional role in maturity transformation. Critics argue that by requiring more stable, often more expensive, long-term funding for assets, the NSFR could disincentivize long-term lending, potentially leading to a shortage of credit for businesses and households and impacting economic growth., Lo⁴n³ger-term loans to nonfinancial businesses and households typically require significant stable funding, which can increase the cost for banks.

An²other criticism suggests that the NSFR, while effective at a micro-prudential level, may not fully address all negative externalities or systemic risk within the broader financial system. There is also a concern that it could encourage certain maturity transformation activities to migrate to the "shadow banking" sector, where regulatory oversight is less stringent.

Re¹garding the concept of "backdating," it is crucial to clarify that the Net Stable Funding Ratio, like other regulatory financial ratios, is a metric calculated based on a bank's actual financial data at a specific point in time. Any attempt to "backdate" or alter past financial statements to improve a historical NSFR figure would constitute fraudulent misrepresentation and would be in severe violation of accounting principles and regulatory requirements. Regulatory compliance mandates accurate and timely reporting of financial positions, not retrospective adjustments to meet a desired ratio.

Net Stable Funding Ratio vs. Liquidity Coverage Ratio (LCR)

The Net Stable Funding Ratio (NSFR) and the Liquidity Coverage Ratio (LCR) are both integral parts of the Basel III framework designed to enhance bank liquidity. However, they address different time horizons and objectives:

While the LCR focuses on a bank's ability to withstand a severe, short-term liquidity stress scenario by holding a buffer of highly liquid assets, the NSFR ensures that a bank's long-term assets and off-balance sheet exposures are supported by a stable funding structure over a longer period. They are complementary metrics, with the NSFR preventing an overreliance on short-term funding for long-term assets, and the LCR ensuring immediate liquidity under stress.

FAQs

What is the primary goal of the Net Stable Funding Ratio?

The primary goal of the Net Stable Funding Ratio is to promote the long-term financial stability of banks by requiring them to maintain a stable funding profile in relation to their assets and off-balance sheet activities. This helps to prevent liquidity issues that arose during past financial crises.

How does stable funding contribute to a bank's resilience?

Stable funding, such as long-term debt, equity, and reliable customer deposits (e.g., retail deposits), provides a dependable source of capital that is less prone to sudden withdrawals or market disruptions. This stability allows banks to fund their less liquid assets more securely, reducing their exposure to liquidity risk and enhancing their ability to operate even in adverse conditions.

Is the Net Stable Funding Ratio universally applied?

The Net Stable Funding Ratio is part of the international Basel III framework, which is intended for global application to internationally active banks. However, its implementation details and scope can vary slightly across different national jurisdictions, as each country's regulators adopt and tailor the standard to their specific market conditions.
