A bank’s central function is transformation: it accepts liabilities that may be short-term, withdrawable, or repriced frequently and invests in assets that may be longer-term, less liquid, or exposed to credit and market risk. This transformation creates earnings, but also creates vulnerability. A bank may be solvent yet unable to meet withdrawals, or liquid yet exposed to a damaging rise in interest rates. Asset–liability management (ALM) provides the framework for balancing these risks while preserving profitability, regulatory compliance, and depositor confidence.

Treasury is the organizational and market-facing function that implements much of this framework. It manages cash, funding, investment portfolios, money-market transactions, foreign exchange, derivatives, and internal pricing of funds. International banking extends these activities across currencies, jurisdictions, legal systems, and political environments. Trade finance and correspondent banking connect customers and banks to the global payments and settlement system.

The subject is therefore both quantitative and institutional. Sound decisions require maturity analysis, interest-rate measurement, liquidity planning, market knowledge, governance, and ethical judgment.

Learning objectives

1. The architecture of ALM

1.1 Balance-sheet transformation

Assets	Liabilities and equity
Cash and reserves	Demand deposits
Loans and advances	Savings and time deposits
Securities	Wholesale borrowings
Interbank placements	Subordinated debt
Other assets	Equity capital

ALM does not seek to eliminate all mismatches. Maturity transformation is a legitimate source of banking income. The objective is to keep liquidity, interest-rate, foreign-exchange, capital, and market risks within the limits approved by the board and consistent with the bank’s strategy.

1.2 Governance structure

The board normally approves risk appetite, while an asset–liability committee (ALCO) converts that appetite into limits and policies. Treasury executes funding and investment decisions within those limits. The risk function independently measures and challenges exposures; finance reports performance; internal audit tests controls. A clear separation between dealing, confirmation, settlement, valuation, and control reduces fraud and operational risk.

2. Liquidity-risk management

Liquidity risk is the risk that an institution cannot meet obligations when due without unacceptable losses. It has two related forms. Funding liquidity risk concerns the ability to obtain cash. Market liquidity risk concerns the ability to sell or finance an asset without a substantial price concession.

2.1 Sources and uses of liquidity

Expected sources include deposit inflows, loan repayments, securities maturities, wholesale borrowing, central-bank facilities, and asset sales. Expected uses include deposit withdrawals, loan funding, debt maturities, collateral calls, operating expenses, and committed credit lines.

A liquidity buffer usually consists of cash, central-bank balances, and high-quality liquid assets that can be sold or pledged quickly. Holding such assets has a carrying cost, but insufficient liquidity can produce forced sales, reputational damage, or failure.

2.2 Maturity ladder and cumulative gap

A maturity ladder groups contractual cash inflows and outflows into time buckets. The net liquidity gap for bucket t is:

Here, Inflows_t and Outflows_t are cash amounts in the same currency and time bucket. A negative cumulative gap indicates that identified funding needs exceed identified inflows. The calculation is a contractual analysis and should not be interpreted mechanically: many deposits are behaviourally stable, while some credit lines are drawn only under stress.

Worked example: a liquidity ladder

Item	Amount (CU million)
Loan repayments	42
Securities maturities	18
Expected deposit inflows	25
Deposit withdrawals	60
Wholesale debt maturity	35
Operating and other payments	8

The bank must cover an 18 million shortfall through existing cash, sale or repo of eligible securities, new funding, or reduction of discretionary asset growth. The result does not prove insolvency; it identifies a funding requirement under the assumptions used.

2.3 Liquidity metrics and stress testing

Common indicators include the liquid-assets-to-total-assets ratio, liquid-assets-to-short-term-liabilities ratio, loan-to-deposit ratio, concentration measures, and regulatory liquidity ratios such as the Liquidity Coverage Ratio (LCR), where applicable. The LCR is broadly designed to ensure that high-quality liquid assets cover stressed net cash outflows over a specified short horizon. Exact regulatory definitions, haircuts, inflow caps, and implementation dates depend on jurisdiction.

Stress testing should examine institution-specific, market-wide, and combined scenarios. Examples include rapid deposit withdrawals, wholesale-market closure, collateral haircuts, rating downgrade, currency depreciation, operational disruption, or simultaneous drawdown of committed facilities. A contingency funding plan assigns escalation triggers, responsible officers, communication procedures, collateral sources, and emergency funding options.

3. Interest-rate risk in the banking book

Interest-rate risk arises because assets and liabilities may reprice at different times, have different reference rates, or respond differently to market-rate changes. It affects net interest income and the economic value of equity.

3.1 Repricing-gap analysis

Repricing Gap = Rate-sensitive Assets − Rate-sensitive Liabilities

If the gap is positive, more assets than liabilities reprice in the bucket. A simplified change in net interest income for a small rate movement is:

∆NII is the change in net interest income per chosen annualized period, the gap is measured in currency, and ∆i is the decimal change in the relevant interest rate. The approximation assumes a parallel and immediate rate change, unchanged balances, no behavioural changes, and equal repricing sensitivity. These assumptions are often unrealistic; therefore, gap analysis is a screening tool rather than a complete valuation model.

Worked example: repricing exposure

A bank has 80 million of assets repricing within three months and 110 million of liabilities repricing within the same period. The gap is −30 million. If relevant rates rise by 1 percentage point, or 0.01, the approximate change in annualized net interest income is:

∆NII ≈ (−30,000,000) × 0.01 = −300,000

The negative result indicates that liabilities reprice upward by more than assets. It is not a forecast of total profit because fixed-rate items, fees, defaults, customer behaviour, and basis differences are excluded.

3.2 Duration and economic value

Duration measures the sensitivity of a bond’s price to yield. Macaulay duration is the present-value-weighted average time of cash flows:

Here, CF_t is the cash flow at time t, PV(CF_t) is its present value, and price is the bond’s present value. Modified duration for annual compounding is:

The approximation assumes a small parallel yield change and ignores convexity. Price and yield move in opposite directions. Longer-duration assets generally lose more value when yields rise.

For a bank, duration analysis can compare the sensitivity of the asset portfolio with that of liabilities. A more complete economic-value-of-equity analysis discounts expected asset and liability cash flows under alternative yield curves. It is especially important for fixed-rate loans, bonds, mortgages with prepayment options, and long-term deposits whose behavioural maturity differs from contractual maturity.

3.3 Managing interest-rate exposure

Tools include changing loan and deposit pricing, altering investment duration, issuing fixed- or floating-rate debt, using interest-rate swaps, purchasing caps or floors, and matching repricing characteristics. Management must consider basis risk: a loan may reprice with a lending index while funding reprices with another index. Optionality is also important: borrowers may prepay when rates fall, while depositors may withdraw or migrate funds when rates rise.

4. Treasury investment portfolios

Banks hold securities for liquidity, income, market-making, collateral, and regulatory purposes. Portfolio policy should specify permitted instruments, credit quality, duration, issuer and sector limits, currency limits, valuation methods, and delegated authority.

Typical instruments include government bills and bonds, central-bank instruments, high-grade corporate debt, certificates of deposit, commercial paper, and repurchase agreements. Equity holdings are usually subject to stricter constraints because of volatility and capital treatment.

Accounting classification and regulatory capital treatment influence reported earnings and incentives. Mark-to-market gains may be volatile, whereas holding an instrument to collect contractual cash flows may produce a different accounting pattern, subject to applicable standards and business-model tests. Accounting treatment must never be used to conceal economic risk.

5. Money markets and funding

The money market deals mainly in short-term borrowing and lending. Participants include commercial banks, central banks, governments, money-market funds, corporations, and dealers. Instruments include interbank loans, repos, reverse repos, treasury bills, commercial paper, and certificates of deposit.

A repurchase agreement combines a sale of securities with an agreement to repurchase them later. Economically, it is usually collateralized borrowing. Key risks include collateral valuation, haircut changes, counterparty default, settlement failure, and legal uncertainty over close-out rights.

Treasury chooses between secured and unsecured funding, retail and wholesale sources, short and long maturities, and domestic and foreign markets. Diversification reduces dependence on one market, but increases documentation, currency, and operational complexity.

6. Foreign-exchange markets

Foreign exchange (FX) is the market for exchanging one currency for another. A quotation must identify the base and terms currency. If EUR/USD = 1.1000, one euro costs 1.1000 US dollars. The inverse quotation is:

A bank’s net open position in a currency is affected by foreign-currency assets, liabilities, expected transactions, and off-balance-sheet contracts. A long position means foreign-currency assets exceed liabilities; a short position means liabilities exceed assets. Exchange-rate movements can affect trading income, translated earnings, capital, and customer repayment capacity.

Spot, forward, and swap transactions

A spot transaction is settled under the market’s standard short settlement convention. A forward transaction fixes an exchange rate today for settlement at a future date. An FX swap combines a near-date exchange with a reverse future exchange and is commonly used for funding and liquidity management.

Under simplified covered interest parity, ignoring transaction costs, credit risk, taxes, and market frictions:

F = S × [(1 + i_d × T) ÷ (1 + i_f × T)]

Here, F is the forward price in domestic currency per unit of foreign currency, S is the spot price, i_d and i_f are domestic and foreign annual interest rates, and T is time in years under simple interest. The quotation convention must remain unchanged. Actual pricing may include cross-currency basis, liquidity premiums, credit adjustments, and different day-count conventions.

Worked FX example

If the spot rate is 1.1000 USD per EUR, the annual US rate is 5%, the euro rate is 3%, and the maturity is six months:

F = 1.1000 × [(1 + 0.05 × 0.5) ÷ (1 + 0.03 × 0.5)]

F = 1.1000 × (1.025 ÷ 1.015) ≈ 1.1108 USD/EUR

7. Derivatives in banking

Derivatives derive value from an underlying rate, currency, security, index, or commodity. Banks use them for hedging, market-making, and customer solutions, but derivatives can increase leverage and create counterparty, collateral, model, legal, and liquidity risks.

A hedge should have a documented objective, identified risk, suitable instrument, effectiveness assessment, counterparty controls, collateral plan, and exit strategy. A derivative can reduce one exposure while creating another. For example, an interest-rate swap may reduce fixed-rate risk but introduce basis risk and counterparty exposure.

8. Funds transfer pricing

Funds transfer pricing (FTP) assigns the internal cost or benefit of funding and liquidity to business units. It allows management to distinguish customer-product performance from treasury decisions.

A basic matched-maturity approach charges a lending unit an internal funding rate and credits a deposit unit for funds supplied. A simplified product margin is:

Product Margin = Customer Yield − FTP Charge − Expected Credit Cost − Operating Cost

For a deposit product, the FTP credit may be based on the value of stable funding, adjusted for reserve requirements, liquidity value, optionality, and behavioural maturity. A robust FTP system may include a term curve, liquidity premium, contingent funding cost, capital allocation, and optionality adjustments.

FTP is an internal managerial tool, not necessarily the price charged to customers. Poor FTP can reward excessive maturity transformation, hide liquidity subsidies, or encourage volume growth without risk-adjusted profitability.

9. International banking and trade finance

International banking exposes institutions to sovereign, transfer, country, sanctions, legal, tax, settlement, and currency risks. The bank must understand both the customer transaction and the jurisdictions involved.

9.1 Trade-finance instruments

Documentary credit (letter of credit): the issuing bank undertakes to pay a beneficiary against presentation of documents complying with the credit’s terms. Banks deal in documents, not in the physical goods. The issuing bank therefore assesses the applicant, country, correspondent, documents, and reimbursement arrangements.

Documentary collection: banks transmit documents and collect payment or acceptance, but generally do not provide the same payment undertaking as a letter of credit.

Bank guarantee or standby letter of credit: the bank promises payment if the applicant fails to perform or pay, subject to the instrument’s terms.

Bills of exchange and trade loans: these may finance the period between shipment, delivery, and customer payment.

Trade operations require accurate document checking, sanctions screening, dual control, fraud detection, and careful application of governing rules such as internationally recognized documentary-credit and guarantee standards where incorporated into the contract.

9.2 Correspondent banking

A correspondent bank provides services to another bank, including payment clearing, remittances, trade processing, cash management, and access to a foreign currency or settlement system. A respondent bank uses the correspondent relationship to reach markets where it lacks a direct presence.

Correspondent banking requires due diligence on ownership, licensing, controls, customer base, sanctions exposure, transaction purpose, and nested relationships. A payable-through account or opaque intermediary arrangement can increase money-laundering and sanctions risk. Banks should maintain transaction monitoring, escalation procedures, periodic review, and the ability to terminate relationships when risk cannot be controlled.

10. Governance, regulation, ethics, and technology

Treasury decisions are constrained by prudential regulation, accounting standards, market-conduct rules, anti-money-laundering and counter-terrorist-financing requirements, sanctions, data protection, and local foreign-exchange controls. Regulation varies by jurisdiction; students and practitioners must consult current local rules rather than rely on a textbook summary.

Important governance practices include independent risk limits, reliable data lineage, model validation, stress testing, documented valuation, segregation of duties, and timely escalation. Senior management should understand not only expected profit but also tail losses, liquidity optionality, and the speed at which risk can change.

Ethical issues include misleading customers about FX costs, exploiting information asymmetry, manipulating benchmark submissions, hiding losses through valuation assumptions, and using customer information improperly. The principle of treating customers fairly applies even when a transaction is legally permissible.

Technology supports real-time liquidity dashboards, automated reconciliation, electronic FX dealing, collateral optimization, and machine-learning alerts. Artificial intelligence can identify unusual payment patterns or improve forecasting, but it may generate false positives, embed historical bias, or produce opaque decisions. Human accountability, explainability, access controls, validation, cybersecurity, and model-risk governance remain necessary. AI should support—not replace—professional judgment in high-impact treasury decisions.

11. Integrated illustrative case: Meridian Bank

Background

Meridian Bank is a medium-sized commercial bank with a large portfolio of fixed-rate five-year loans, floating-rate corporate deposits, and a government-bond portfolio. It also finances importers and maintains a US-dollar correspondent account.

Problem

Market interest rates are expected to rise. At the same time, several wholesale borrowings mature within three months. The bank has a contractual one-month negative liquidity gap and a negative short-term repricing gap. Its US-dollar import-finance assets exceed dollar liabilities, creating a long dollar position.

Analysis

ALCO first separates three issues. The funding maturity problem could force expensive refinancing. The negative repricing gap means funding costs may rise faster than loan income. The long dollar position means a fall in the dollar’s value could reduce the domestic-currency value of the net position. A single ratio cannot capture all three exposures.

Treasury constructs a daily liquidity forecast, a contractual and behavioural maturity ladder, and severe but plausible stress scenarios. Risk management independently tests assumptions about deposit stability and bond-market liquidity. Finance estimates the effect on net interest income and economic value.

Approach and solution

Meridian increases its immediately available liquidity buffer, diversifies maturities rather than refinancing all debt at once, and pre-funds part of the upcoming maturity. It shortens the duration of a portion of the bond portfolio while preserving enough high-quality liquid assets for stress needs. It uses an appropriately documented interest-rate hedge for the remaining exposure and a forward or swap structure to reduce the dollar position, subject to counterparty and collateral limits.

The bank also revises FTP so that the fixed-rate lending unit bears the cost of long-term funding and the deposit unit receives credit for stable funding. Trade-finance operations strengthen document review and sanctions screening. The board receives a dashboard showing liquidity survival, stress losses, hedge effectiveness, limit utilization, and concentrations.

Outcome

The bank reduces sensitivity to rising rates and avoids dependence on a single refinancing date. It retains capacity to support legitimate trade customers and meets internal risk limits. Profit is somewhat lower because liquidity and hedging have costs, but earnings become more resilient.

Learning points

Challenges and limitations

ALM models depend on incomplete information and uncertain behaviour. Deposits may be more stable than their contractual terms suggest, but confidence can change quickly. Loan prepayments, deposit migration, collateral haircuts, and market closures are difficult to forecast. Historical correlations can fail during crises. Duration and gap measures simplify complex cash flows; derivatives may introduce model and basis risk; stress scenarios may be too mild or too severe. International operations add legal conflicts, time-zone issues, settlement risk, and geopolitical uncertainty.

Accordingly, no single metric is sufficient. Banks should combine limits, scenario analysis, reverse stress testing, market intelligence, qualitative judgment, and strong governance.

Best-practice checklist

Chapter Summary

Asset–liability management coordinates a bank’s assets, liabilities, capital, liquidity, and market exposures. Liquidity management uses maturity ladders, cumulative gaps, buffers, stress tests, and contingency funding plans. Interest-rate risk can be screened through repricing gaps and analysed more fully using duration, economic-value measures, and scenario analysis. Treasury manages investment portfolios, money-market funding, collateral, and market transactions. Foreign-exchange operations require consistent quotation, position measurement, and awareness of spot, forward, swap, and parity relationships. Derivatives can hedge risk but create counterparty, collateral, model, legal, and liquidity exposures. Funds transfer pricing allocates funding and liquidity costs internally and improves performance measurement. International banking adds trade-finance, correspondent, sovereign, sanctions, settlement, and country risks. Effective practice depends on governance, independent control, reliable data, ethical conduct, and integrated stress testing.
