Powerpoint: Commercial Banking Module 4: Liquidity and Asset Liability Management

Overview of Asset Liability Management (ALM)

• Definition of ALM: Bank asset and liability management is the professional practice of balancing a bank’s current and long-term potential earnings against the necessity of maintaining adequate liquidity and managing appropriate exposure to interest rate risks.

• Strategic Formulation: Every bank develops unique strategies based on individual characteristics:

  • Customer base.

  • Deposit mix.

  • Loan mix.

  • Overall pricing strategies.

  • Risk profile.

• Risk Assessment: Evaluating risk exposure and active risk management are critical components of a bank's overall financial performance.

• Addressing Mismatches: Banks must manage mismatches between asset and liability maturities or durations. Tools for this management include:

  • Investment securities.

  • Hedging strategies.

• Core Policy Focus: Both interest rate risk and liquidity risk are the primary areas addressed when formulating bank strategy and policy regarding asset liability management.

Liquidity, Asset, and Liability Management Strategies

• Liquidity Management Philosophy: This strategy must balance the trade-off between risk and returns. It is inextricably linked with asset-liability management.

• Primary Risks to Performance: For any commercial bank to perform successfully, it must effectively manage liquidity risk and interest rate risk.

• Asset Management Strategy: This involves meeting liquidity needs primarily through the use of "near-cash assets," which are the most liquid assets the bank holds.

• Liability Management Strategy: This strategy addresses liquidity needs by tapping into outside sources and borrowings, including:

  • The Discount Window.

  • Federal Funds (Fed Funds).

  • Other external borrowings.

• Predictive Requirements: Banks are required to predict several directional flows:

  • The movement of deposits (inflows and outflows).

  • Loan activities (advances and paydowns).

• The Investment Bridge: Investment strategies must include securities that are "readily liquid and accessible." These securities serve as a bridge to ensure liquidity is available when needed.

• Impact on Profitability:

  • Excess Liquidity: Can negatively affect profitability because funds are not being deployed into higher-yielding assets.

  • Liquidity Pressure: Can decrease profits if the bank is forced to borrow at a cost higher than its typical cost of funds.

The Loan to Deposit Ratio

• Concept: This ratio measures the portion of a bank's deposits that have been "loaned out."

• Returns vs. Risk: Conceptually, a higher loan to deposit ratio should yield higher returns, provided that the associated risks are managed appropriately.

• Operational Safety: Banks operating with a higher loan to deposit ratio generally ensure they have access to inexpensive borrowing sources if liquidity needs arise suddenly.

Historical Context: Liquidity during the Great Recession

• Regulatory Oversight: Banking regulators closely monitor a bank's liquidity management strategy and the specific policies surrounding it.

• Safety and Soundness Concerns: During the Great Recession, large depositors (with millions in cash) became concerned about the safety of deposits exceeding the FDIC limits.

• FDIC Limits at the Time: During the crisis, the FDIC insurance limit was only $100,000 per client.

• Flight to Quality: Due to unrest, large depositors shifted funds into U.S. Treasuries, which are considered the safest possible investment.

• Yield Impact: The massive movement into Treasuries drove yields to extremely low levels; there were discussions regarding negative interest rates, though they never actually occurred.

• Legislative Mitigation: To counter the movement of funds out of the banking system, Congress passed a temporary rule that allowed for unlimited FDIC insurance for depositors on non-interest-bearing bank deposits.

Case Study: The Failure of Silicon Valley Bank (SVB)

• Failure of Liquidity Management: SVB failed largely because it invested the majority of its deposits into long-term fixed-rate securities during a period of zero interest rates.

• Interest Rate Environment: While most banks had been alert to the risk of rising interest rates following the Great Recession, SVB's strategy left them exposed.

• Classification Error: SVB classified its investment portfolio as "Hold to Maturity" (HTM), which meant these assets were not readily available for sale to generate liquidity.

• 2022 Market Shift: As interest rates increased rapidly in early 2022, the value of SVB’s fixed-rate securities dropped significantly.

• The Liquidity Trap: The bank could not sell these investments for liquidity because the market value loss was too high, compounded by the HTM classification.

• Concentration Risk: SVB suffered from an over-concentration of non-FDIC insured deposits. Their client base was not diversified, consisting largely of venture capital and private equity depositors.

• Lesson on Diversification: Investment decisions should follow the same sound diversification policies that banks apply to their loan portfolios.

Reserve Requirements and Regulations

• Definition: A central bank regulation setting the minimum amount of liquid assets a commercial bank must hold.

• Purpose: To ensure banks have enough liquidity to handle sudden and unexpected deposit withdrawals.

• Reserve Components: Reserves consist of physical cash held at the bank or deposits kept at the Federal Reserve Bank.

• Calculation Method: Ratios are based on "net transaction deposits" using a tiered structure based on account size.

• Net Transaction Deposits Formula:

  • $\text{Net Transaction Deposits} = \text{Total Transaction Accounts} - \text{Amounts due from other depositor institutions}$

  • Note: Transaction accounts exclude savings and time deposits.

  • Note: "Due from other banks" excludes interbank settlement accounts.

Reserve Requirement Ratios and Evolution

• COVID-19 Policy Change: In March 2020, the Federal Reserve Board reduced reserve requirement ratios to $0\%$.

• Pre-2020 Tiered Ratios:

  • Accounts below a set exemption dollar amount: $0\%$.

  • Accounts above the exemption but below the "low reserve tranche": $3\%$.

  • Accounts above the "low reserve tranche": $10\%$.

• Critical Observation on SVB: Even if pre-2020 reserve requirements had been in place, it is unlikely they would have prevented SVB's failure. This is due to the extreme "velocity" of the deposit run, where funds were withdrawn electronically in just two days. SVB was not operationally prepared to access borrowing sources at that speed.

Tools for Accessing Liquidity

• Federal Funds (Fed Funds):

  • In times of excess liquidity, banks sell fed funds overnight to correspondent banks.

  • In times of liquidity need, banks buy fed funds.

• Borrowing Facilities: Banks maintain facilities with correspondent banks, the Federal Reserve, or other lenders. These can be secured or unsecured.

• Repurchase Agreements (Repos):

  • Short-term (usually overnight) agreements to sell government securities with an agreement to buy them back at a slightly higher price.

  • The seller is effectively the borrower; the buyer is the lender.

  • The buyer's side of this transaction is called a "Reverse Repurchase Agreement."

• Discount Window: A collateralized line of credit facility at the Federal Reserve used by banks to access liquidity.

Interest Rate Risk and Duration Risk

• Management Decisions: Daily banking operations—buying/selling securities and pricing loans/deposits—are heavily influenced by interest rate sensitivity.

• Key Decision Factors: The outlook on interest rates and the sensitivity/composition of the deposit funding base.

• Duration Risk Definition: The risk that a bond, fixed-income investment, or loan will lose value because of changes in interest rates.

• Inverse Relationship: Bonds and fixed-rate investments move inversely to interest rates. When rates increase, the value of fixed-rate investments decreases.

• Loan Duration Risk: If interest rates rise, a fixed-rate loan may be valued below the current market rate.

• Deposit Duration Risk: This occurs when a bank uses short-term liabilities (deposits) to invest in long-term fixed-rate loans or investments.

Interest Rates and Bank Profitability

• Net Interest Income (NII): NII is directly correlated to:

  • Changes in interest rates.

  • Composition of assets and liabilities.

  • Volume of earning assets and liabilities.

• Asset Composition: Since bank assets are primarily earning assets, the loan mix is vital. Banks must balance maturity (duration) risk with pricing risk for both assets and deposits.

• Monitoring Activity: Banks must keep a "tight watch" on loan demand and deposit activity.

• Funding Pressure: Because deposits are difficult to predict, banks must often adjust loan growth based on deposit activity. Insufficient deposits force banks to use expensive borrowing alternatives, hurting profitability.

Historical Failures in Interest Rate Management

• The Savings and Loan (S&L) Crisis: S&Ls made the mistake of making long-term fixed-rate loans while their funding sources (deposits) were short-term. They mismatched their funding sources and failed at long-term pricing.

• SVB vs. S&L: SVB made the same mismatch mistake, but specifically with the duration risk of their investments rather than their loans.

• SVB's Specific Asset Problem: While the quality of their investments was sound, the duration was over 10 years for the majority of the portfolio, which caused the failure.

The Asset Liability Committee (ALCO)

• Structure: Most banks manage ALM through a committee structure known as the Asset Liability Committee (ALCO or ALM).

• Responsibilities:

  • Discussing the pricing of loans and deposits.

  • Reviewing and introducing new product offerings aligned with the overall strategy.

  • Adapting strategy as interest rates move up or down.

• Risk Factors: The committee considers interest rate sensitivity, liquidity, credit risk, and investment risk.

• Strategic Goal: Balancing adequate returns against a surplus of liquidity, while considering the bank's specific characteristics and loan mix.

• Committee Composition: ALCO typically includes a wide range of members knowledgeable about the investment portfolio, deposit activity, and loan demand (front-line impacts).

GAP and Interest Sensitivity Management

• Purpose of GAP Analysis: To measure the risk to the bank's total Net Interest Income and determine how the bank is positioned to profit or lose from rate changes.

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

• Rate Sensitive Assets (RSAs): Assets that reprice within a designated time frame.

• Rate Sensitive Liabilities (RSLs): Liabilities that reprice within a designated time frame.

• Dollar Gap Ratio Formula:

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

Positive and Negative GAP Dynamics

• Positive GAP (\text{RSAs} > \text{RSLs}):

  • If Rates Rise: Both assets and liabilities reprice. Assuming they rise by the same margin, NII increases because more assets are repricing upward.

  • If Rates Fall: NII declines because interest income falls with greater velocity than deposit costs.

• Negative GAP (\text{RSLs} > \text{RSAs}):

  • If Rates Rise: NII declines because there are more liabilities (deposits) to reprice higher, increasing interest expense.

  • If Rates Fall: NII improves because the interest expense falls with greater velocity than the income on earning assets.

Practical GAP Analysis Example

• Scenario: A bank issues $20 \text{ million}$ in 5-year fixed-rate loans at $8\%$. It funds these loans with $20 \text{ million}$ in 1-year CDs at $5\%$.

• Initial Spread: $3.0\%$.

• Rising Rate Scenario: Interest rates rise. The loan rate remains at $8\%$ (fixed). At the end of the year, the CD reprices to $5.5\%$. The spread decreases by $0.5\%$ to a new spread of $2.5\%$.

• Falling Rate Scenario: Interest rates fall. The CD reprices at $4.5\%$. The spread improves to $3.5\%$.

• Strategic Implication: Banks must establish NII targets and constantly adapt to a dynamic rate environment to manage susceptibility to yield curve changes.

Floating Rate Loans and Deposit Pricing

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

  • Wall Street Prime.

  • SOFR (Secured Overnight Financing Rate).

  • Ameribor.

• Deposit Pricing: Deposits do not automatically reprice as they are not tied to an index.

• Pricing Behavior: Banks are generally slower to increase deposit rates and quicker to lower them. Movement is driven by the competitive landscape and bank safety concerns (volatility).

• Decision Basis: Earning asset rate movement for loans and investments determines the severity and frequency of deposit pricing changes.
