Liquidity and Asset Liability Management

Overview of Module Four: Liquidity and Asset Liability Management

  • Contextual Importance: Asset liability management (ALM) and liquidity have become critical topics due to the rapid interest rate environment changes in recent years. In 2022 alone, there were 1111 rate changes, resulting in rates increasing by larger quantities and with higher velocity than anticipated over a one-year period.

  • Goal of the Module: To bridge the management of the balance sheet (assets) and the income side. Failure to manage liquidity or assets and liabilities effectively results in poor institutional performance.

  • Fundamental Practice: ALM is the practice of balancing a bank's current and long-term potential earnings with the necessity of maintaining adequate liquidity and appropriate interest rate risk exposures.

  • Strategic Formulation: Every bank has a unique strategy based on their specific mix of deposits, loans, customer base, overall pricing, and risk profile.

  • Risk Management Tools: Mismatches in maturity or duration between assets and liabilities must be managed through the use of securities or hedging strategies.

Core Concepts in Liquidity and Asset Management

  • Liquidity Management: A strategy that balances risk with returns. A notable case of failure in this area is Silicon Valley Bank (SVB), which prioritized return over risk management by placing deposits into long-term assets.

  • Asset Management Strategy: Meeting liquidity needs by utilizing the most liquid, near-term assets.

  • Liability Management Strategy: Meeting liquidity needs via outsourced sources, such as borrowings at the Federal Reserve's discount window, Fed funds, and other borrowing facilities.

  • The Investment "Bridge": Investments act as the "bridge to liquidity" or an "accordion." Banks prefer to make high-quality loans first. If deposit growth does not keep up with loan growth, banks can use their investment portfolio (liquid securities) to manage the gap.

  • Controllability of Growth:

    • Loan Growth: Relatively easy to control. A bank can slow growth by increasing interest rates or adding more loan covenants.

    • Deposit Movements: Extremely difficult to predict. Customers do not have to provide notification to move deposits and can exit a bank in a single day.

  • Effect on Profitability: Excess liquidity that is not put to work (invested or loaned) negatively impacts profits. Conversely, pressure on liquidity decreases profits because borrowing money as a source of funds is typically more expensive than core deposits.

The Loan-to-Deposit Ratio as a Liquidity Metric

  • Definition: A ratio measuring how much of a bank's deposits are being utilized for loans.

  • Profitability Implications: A higher loan-to-deposit ratio is generally more profitable, provided the loans are of high quality.

  • Risk Profile Requirements: Banks with high loan-to-deposit ratios must have very predictable deposits (core/relationship deposits) and strong borrowing sources. High ratios with transactional (unpredictable) deposits create a riskier profile.

  • Comparative Examples:

    • Frost Bank: Maintains a conservative approach with approximately a 50%50\% loan-to-deposit ratio, necessitating excellence in investment management.

    • Texas Capital Bank: Operates with a riskier profile of 80%80\% to 90%90\% loan-to-deposit ratio, requiring tight management of the deposit base.

Historical Context of Liquidity Management

  • The Great Recession (2008-2009):

    • Following the failure of Lehman Brothers, there was a massive "flight to safety" as depositors feared for the safety of funds exceeding FDIC limits.

    • At the time, the FDIC insurance limit was $100,000\$100,000 for non-personal entities. These limits applied per bank charter, not per branch.

    • The rush to U.S. Treasuries drove yields so low that there were serious discussions about potential negative interest rates (where depositors pay the bank to hold money).

    • Regulatory Intervention: Congress and regulators implemented TARP and a temporary rule providing unlimited FDIC insurance on non-interest-bearing deposits to stop the systemic flight from the banking system.

    • Current Limit: The temporary rules expired, and the standard FDIC insurance limit was permanently raised to $250,000\$250,000.

  • Silicon Valley Bank (SVB) Failure:

    • Despite a low loan-to-deposit ratio (which usually suggests safety), the bank failed due to a duration mismatch.

    • SVB invested approximately 94%94\% to 95%95\% of its investment portfolio into long-term (1010-year) fixed-rate Treasuries and mortgage-backed securities during a zero-interest-rate environment.

    • Accounting Treatment: They classified these as "Hold to Maturity" (HTM), meaning they could not be easily sold for liquidity without significant accounting consequences.

    • The Crash: As rates rose in 2022, these fixed-rate bonds dropped in value (inverse relationship). The bank had a massive portion of uninsured deposits from sophisticated hedge funds and private equity clients. When concerns rose on a Wednesday, the bank saw $40,000,000,000\$40,000,000,000 in withdrawal attempts by Thursday, followed by another $100,000,000,000\$100,000,000,000 the next day.

Reserve Requirements and Liquid Assets

  • Definition: Federal Reserve regulations setting the minimum amount of liquid assets a bank must hold to protect against sudden deposit withdrawals.

  • Composition: Consists of cash held in the bank vault or deposits held at the Federal Reserve Bank.

  • Historical Tiered Tranches (Prior to March 2020):

    • 0%0\% reserve for accounts below a specific set exemption dollar amount.

    • 3%3\% reserve for accounts above the exemption but below a "low reserve tranche."

    • 10%10\% reserve for accounts exceeding the tranche limit.

  • Current Status: In March 2020, due to COVID-19, the Federal Reserve Board reduced reserve requirement ratios to 0%0\%.

  • Efficiency Limitation: Even if reserve requirements had been in place, they would not have saved SVB due to the sheer velocity of modern electronic fund transfers.

Essential Tools for Accessing Liquidity

  • Fed Funds Sold/Purchased: Banks with excess liquidity sell it overnight to correspondent banks. Banks needing liquidity can purchase it. This is a nightly occurrence.

  • Bank Borrowing Facilities: Facilities established with correspondent banks, the Federal Reserve (Discount Window), or the Federal Home Loan Bank (FHLB). These can be secured or unsecured.

  • Repurchase Agreements (Repos): Short-term (generally overnight) agreements where a bank trades government securities for cash with the agreement to repurchase them. This is akin to a "pawn shop" transaction for banks, avoiding the realization of gains or losses on the income statement.

  • Operational Readiness: Post-SVB, regulators emphasize that banks must be operationally ready to use these tools immediately if deposit fluctuations occur.

Interest Rate Risk and Duration Risk

  • The Spread Business: Banks earn money on the difference between the interest income from assets and interest expense on liabilities.

  • Rate Movement Terminology:

    • Upside Risk: The risk associated with interest rates increasing.

    • Downside Risk: The risk associated with interest rates decreasing.

  • Recent History: Rates moved from near-zero to a cumulative increase of 525525 basis points (bps) starting in 2022.

  • Historical Context: While current rates feel high, they are historically moderate compared to the S&L Crisis/Stagflation era, where loans reached 18%18\%, mortgages were 12%12\%-13%13\%, and money markets paid 10%10\%-12%12\%.

  • Duration Risk Defined: The risk that a bond, fixed-income investment, or loan will lose value due to changes in interest rates. Bonds and fixed-rate investments move inversely to rate changes.

  • Asset/Liability Impacts:

    • Fixed-Rate Loans: If a bank locked in loans at 3%3\% or 4%4\% for 77 to 1010 years when rates were zero, and now deposit costs are higher, the bank's spread is compressed.

    • Deposits: Short-term liabilities invested in long-term fixed assets create significant insolvency risk if rates rise.

The Asset Liability Committee (ALCO)

  • Purpose: A committee that manages the risk around asset liability management via a holistic view of the bank.

  • Responsibilities:

    • Determining the pricing of loans and deposits.

    • Reviewing product offerings (e.g., Certificates of Deposit or CDs).

    • Managing credit risk and investment risk.

  • Strategy Shifts: During low-rate environments, CDs are unpopular. As rates rise, banks may offer products like "one-time bump" CDs, allowing customers to increase their rate once during the term if market rates continue to climb.

  • Front-Line Connection: The committee must monitor the loan pipeline (from relationship managers) and deposit headwinds to make informed decisions.

Gap Management and Interest Sensitivity Analysis

  • Interest Sensitivity: The impact of rate changes on the cost of deposits relative to the return on assets.

  • Key Definitions:

    • Rate Sensitive Assets (RSAs): Assets like loans and investments that reprice within a specific timeframe.

    • Rate Sensitive Liabilities (RSLs): Liabilities like deposits that reprice within a specific timeframe.

  • Dollar Gap Ratio Formula:

    • Dollar Gap Ratio=RSAs−RSLsTotal Assets\text{Dollar Gap Ratio} = \frac{\text{RSAs} - \text{RSLs}}{\text{Total Assets}}

  • Positive Gap (RSAs > RSLs):

    • If rates rise, Net Interest Income (NII) increases because more assets are repricing upward than liabilities.

    • If rates fall, NII decreases.

  • Negative Gap (RSLs > RSAs):

    • If rates rise, NII decreases because interest expense (liabilities) rises faster than interest income.

    • If rates fall, NII improves.

Repricing Dynamics and Floating Indexes

  • Floating Rate Loans: These reprice immediately based on an index. Common indexes include:

    • Wall Street Journal Prime

    • SOFR (Secured Overnight Financing Rate)

    • Ameribor (Note: SOFR and Ameribor replaced LIBOR).

  • Deposit Repricing: Deposits do not reprice automatically. Banks are often slower to increase deposit rates (dragging their feet) until driven to do so by competition (e.g., if a competitor like Frost Bank increases rates, other banks must follow to retain loyal customers).

  • Simple Gap Example:

    • A $20,000,000\$20,000,000 loan at 8%8\% (fixed for 55 years) funded by $20,000,000\$20,000,000 in $1$-year CDs at 5%5\%.

    • Initial Spread: 3%3\%.

    • If rates rise by 0.5%0.5\%, the CD reprices at 5.5%5.5\% while the loan stays at 8%8\%. The spread narrows to 2.5%2.5\%.

    • If rates fall by 2.5%2.5\%, the CD reprices at 2.5%2.5\% while the loan stays at 8%8\%. The spread improves to 5.5%5.5\%.
