Foreign Exchange, Money Markets and Treasury Management

Introduction

International banking connects borrowers, investors, importers, exporters and financial institutions across currencies and jurisdictions. This creates opportunities for funding and investment, but also exposes institutions to exchange-rate, interest-rate, liquidity, settlement, counterparty and regulatory risks. Treasury management is the discipline through which a bank identifies these exposures, measures them, decides which risks to retain, and controls those risks through funding, investment and hedging decisions.

Foreign exchange (FX) markets provide the mechanisms for converting currencies and transferring purchasing power across time. Money markets provide short-term funding and investment, normally for maturities up to one year. Treasury integrates both markets: an institution borrowing in one currency and lending in another is simultaneously managing currency, interest-rate and liquidity exposures.

This chapter develops the mechanics of spot, forward, swap and option transactions; explains exchange-rate quotations and forward pricing; and presents a governance framework for managing treasury risk.

  6. Evaluate liquidity, settlement and counterparty risks.
  7. Design a treasury policy involving limits, hedging, controls and reporting.
  8. Critically assess the benefits and limitations of derivatives-based hedging.

1. The architecture of international treasury

A bank treasury usually performs four related functions:

  • Funding: obtaining stable and cost-effective financing in domestic and foreign currencies.
  • Liquidity management: ensuring that obligations can be met when due, including under stress.
  • Market-risk management: controlling exposures to FX rates, interest rates, credit spreads and securities prices.
  • Balance-sheet management: coordinating assets, liabilities, capital, profitability and regulatory constraints.

The front office executes transactions; the middle office measures risk, validates limits and performs independent valuation; the back office confirms, settles and reconciles transactions. Separation of duties is fundamental. A trader should not be able to initiate, value, confirm and settle the same transaction without independent controls.

A treasury policy normally specifies approved instruments, currencies, counterparties, maturity limits, dealer authorities, stop-loss limits, value-at-risk or stress limits, collateral requirements, accounting treatment and escalation procedures.

2. Foreign-exchange market foundations

2.1 Currency quotations

An exchange rate states the value of one currency in units of another. A quotation of EUR/USD = 1.0850 means that one euro costs 1.0850 US dollars. EUR is the base currency and USD is the quote currency.

A direct quotation expresses the domestic-currency price of one unit of foreign currency. An indirect quotation expresses the foreign-currency value of one unit of domestic currency. The classification depends on the observer’s home country.

Banks quote a bid and an ask. The bid is the price at which the dealer buys the base currency; the ask is the price at which the dealer sells it. Thus, for EUR/USD quoted 1.0848/1.0852, the dealer buys euros at 1.0848 dollars and sells euros at 1.0852 dollars. The spread compensates the dealer for operating costs, inventory risk, volatility and liquidity risk.

2.2 Cross-rates

A cross-rate is calculated from two quoted currency pairs. Suppose:

  • EUR/USD = 1.0800
  • USD/JPY = 150.00

Then:

EUR/JPY = (EUR/USD) × (USD/JPY) = 1.0800 × 150.00 = 162.00

The units confirm the result: EUR × USD/EUR × JPY/USD = JPY. In practice, bid and ask rates must be combined conservatively. A bank buying euros against yen uses the relevant bid prices, while a bank selling euros uses the relevant ask prices. Mid-market cross-rates are useful for analysis but not necessarily executable.

2.3 Spot transactions

A spot FX transaction exchanges two currencies at the prevailing spot rate, normally settling two business days after the trade date for most major currency pairs. Some pairs and market conventions settle on the next business day. Holidays, time zones and local payment systems affect the actual value date.

If an importer must pay USD 2,000,000 and the quoted USD/INR rate is 83.20, the rupee cost is:

INR ext{ amount} = USD ext{ amount} × INR/USD = 2,000,000 × 83.20 = INR 166,400,000

The importer remains exposed until the dollars are purchased or hedged.

2.4 Forward transactions and forward points

An FX forward is an agreement to exchange specified currencies on a future date at a rate agreed today. It is normally an over-the-counter contract and creates counterparty credit exposure unless centrally cleared or otherwise collateralised.

Under covered interest parity, assuming aligned maturities, no material transaction costs, unrestricted capital movement and no arbitrage, the theoretical forward rate is:

F = S × (1 + rd T) / (1 + rf T)

where:

  • F = forward rate in domestic currency per unit of foreign currency;
  • S = spot rate in domestic currency per unit of foreign currency;
  • rd = annualised domestic interest rate;
  • rf = annualised foreign interest rate;
  • T = time to maturity in years.

This simple-interest form is appropriate for short maturities when rates are quoted on a compatible basis. With continuously compounded rates, the corresponding expression is:

F = S × e(rd-rf)T

The formula is a no-arbitrage benchmark, not a guarantee of the market quote. Credit spreads, funding bases, collateral terms, capital costs and market segmentation can create deviations.

Worked example. Assume USD/INR spot S = 83.20, one-year Indian interest rate rd = 6.00%, one-year US interest rate rf = 5.00%, and T = 1. Using simple annual compounding:

F = 83.20 × (1.06/1.05) = 83.20 × 1.0095238 ≈ 84.00

The forward points are:

Forward ext{ points} = F - S = 84.00 - 83.20 = 0.80

The dollar has a forward premium of approximately 0.96% in rupee terms, because the domestic interest rate is higher. Forward points may be quoted in pips or points; their scale depends on the currency pair and market convention.

2.5 FX swaps

An FX swap combines a near-date exchange with a reverse exchange on a later date. It is widely used to manage short-term currency funding and liquidity. A bank may borrow dollars against euros today and reverse the transaction in one month.

The near leg is generally priced at or near spot; the far leg reflects the swap points associated with the interest differential and market funding conditions. An FX swap differs from a currency swap, which generally exchanges principal and interest cash flows over a longer period and may involve periodic interest payments.

FX swaps can reduce immediate funding pressure but do not eliminate risk. They create rollover risk if the transaction must be renewed, counterparty risk over the contract life, and liquidity risk if market prices become stressed.

2.6 FX options

An FX option gives the buyer the right, but not the obligation, to buy or sell one currency against another at a specified strike rate on or before an expiry date. A call on foreign currency protects against appreciation of the foreign currency; a put on foreign currency protects against depreciation.

The buyer pays a premium. The seller receives the premium but assumes potentially substantial market risk. A European option can be exercised only at expiry; an American option can be exercised at any time up to expiry. A vanilla option’s value depends on spot, strike, volatility, time to expiry, interest rates and the currency pair’s quotation convention.

For a foreign-currency call, the payoff at expiry, expressed in domestic currency per unit of foreign currency, is:

Payoff = max(ST - K, 0)

where ST is the expiry spot rate and K is the strike. Net profit to the buyer equals payoff minus the premium, after ensuring both are expressed in the same units. Options provide asymmetric protection: the buyer can benefit from favourable movements while retaining the right not to exercise, but this flexibility has a price.

A forward locks the rate and removes both adverse and favourable participation. An option establishes a worst-case exchange rate while preserving potential benefit from favourable movements. Collars, participating forwards and barrier options reduce or redistribute premium costs, but they add complexity and may introduce contingent or model risk.

3. Exposure measurement and hedging decisions

3.1 Types of currency exposure

Transaction exposure arises from contracted foreign-currency receivables, payables, loans or interest payments. It is measurable and often hedgeable.

Translation exposure arises when the financial statements of a foreign subsidiary are translated into the reporting currency. It may affect reported equity or earnings without creating an immediate cash flow.

Economic exposure is the longer-term effect of exchange rates on competitiveness, prices, demand, costs and enterprise value. It is difficult to isolate because it interacts with business strategy.

A treasury exposure report should show currency, direction, amount, value date, hedge status, counterparty, accounting designation and stress sensitivity. Netting exposures across business units reduces unnecessary transactions, but netting must respect legal, operational and settlement constraints.

3.2 Natural and financial hedges

A natural hedge matches foreign-currency revenues with foreign-currency costs or borrows in the currency in which cash flows arise. Financial hedges use forwards, swaps, options or futures. The appropriate hedge depends on certainty of the exposure, maturity, liquidity, accounting objectives, counterparty capacity and management’s tolerance for residual risk.

A forecast export receipt that is highly probable may be hedged with a forward. A highly uncertain forecast may be hedged gradually or with an option. Hedging a forecast that never occurs can create a speculative position, so treasury policies should distinguish committed, highly probable and merely budgeted exposures.

4. Money markets and interest-rate risk

The money market supports short-term borrowing, lending and liquidity transformation. Instruments include interbank deposits, certificates of deposit, commercial paper, Treasury bills, repurchase agreements (repos), reverse repos, bankers’ acceptances and short-dated central-bank facilities.

A repo is a secured sale of securities with an agreement to repurchase them later. The economically equivalent reverse repo is the cash lender’s perspective. Repo markets are important because collateral reduces unsecured credit exposure, although valuation, margin and collateral-liquidity risks remain.

4.1 Discount instruments and yield

For a simple interest-bearing investment, maturity value is:

A = P(1 + rT)

where P is principal, A is maturity amount, r is the annual rate and T is the year fraction. The interest amount is A-P.

For a discount instrument quoted on a simple discount basis:

P = M(1 - dT)

where M is face value and d is the annual discount rate. Discount yield and investment yield are not identical; comparisons require conversion to a common day-count and compounding basis.

4.2 Interest-rate exposure

A bank with fixed-rate assets funded by floating-rate liabilities is exposed to rising rates because funding costs may increase while asset income remains fixed. A bank with floating-rate assets funded by fixed-rate liabilities is exposed to falling rates. Duration provides a first-order measure of bond-price sensitivity:

∆P/P ≈ -Dmod × ∆y

where Dmod is modified duration and ∆y is the change in yield expressed as a decimal. The approximation assumes a relatively small parallel yield movement and ignores convexity. For larger changes or non-parallel curve movements, key-rate duration, scenario analysis and full revaluation are preferable.

Interest-rate swaps can convert fixed-rate payments into floating-rate payments or the reverse. Futures and options such as caps, floors and swaptions provide additional tools. A hedge should be assessed against the underlying exposure, basis risk, maturity mismatch and collateral requirements—not merely against the notional amount.

5. Liquidity, settlement and counterparty risk

5.1 Liquidity risk

Funding liquidity risk is the inability to meet obligations when due. Market liquidity risk is the inability to sell or hedge a position without materially affecting its price. Treasury monitors contractual cash-flow gaps, high-quality liquid assets, available collateral, funding concentration, survival horizons and stress outflows.

A liquidity stress test may combine deposit withdrawals, collateral calls, foreign-currency funding disruption, rating deterioration and market closure. Foreign-currency liquidity must be assessed by currency; surplus liquidity in one currency cannot always be transferred rapidly to cover another currency’s deficit.

5.2 Settlement risk

Settlement risk arises when one party delivers a currency but does not receive the counter-currency. Payment-versus-payment systems such as CLS reduce principal risk for eligible transactions, but operational, legal and funding risks remain. Cut-off times, nostro account balances, sanctions screening, reconciliation and exception management are essential controls.

5.3 Counterparty and credit valuation risk

An OTC derivative creates current exposure when it has positive replacement value and potential future exposure because its value may move further in the counterparty’s favour. Master netting agreements, collateral, margining, credit limits and central clearing can reduce risk. Credit valuation adjustment (CVA) reflects the market value of counterparty credit risk; funding valuation adjustment and margin valuation adjustment may also be relevant in pricing and risk management.

6. Treasury governance and risk framework

An effective framework follows a cycle:

  1. Identify: map contractual and behavioural cash flows by currency, rate basis and maturity.
  2. Measure: calculate net positions, sensitivities, stress losses, liquidity gaps and potential exposure.
  3. Decide: select natural funding, instruments and hedge ratios consistent with policy.
  4. Execute: obtain competitive quotes and document approvals.
  5. Confirm and settle: independently confirm trade economics and settle through approved channels.
  6. Monitor and report: compare actual positions with limits and investigate exceptions.
  7. Review: back-test models, evaluate hedge effectiveness and update assumptions.

Important controls include independent price verification, model validation, valuation reserves, limit hierarchies, segregation of duties, audit trails, legal documentation, business continuity and incident escalation. Treasury should not optimise trading income at the expense of liquidity resilience or the institution’s risk appetite.

Regulatory expectations commonly address liquidity coverage, stable funding, large exposures, market risk, capital, derivatives reporting, margin and conduct. Exact requirements depend on jurisdiction and institution type; therefore, internal policy must be aligned with applicable central-bank, prudential and accounting rules.

7. Applied case: an illustrative bank exposure

Background

Illustrative Bank has a USD 10 million six-month export receivable and a EUR 8 million six-month loan. Its reporting currency is INR. Management expects the dollar to weaken against the rupee but is uncertain about the euro. The bank also has short-term rupee liabilities that reprice monthly.

Problem

The export receivable creates a long-USD position: a fall in USD/INR reduces its rupee value. The euro loan creates a short-EUR liability exposure: a rise in EUR/INR increases the rupee value of repayment. Monthly repricing creates interest-rate exposure, while the different currencies and dates create liquidity and basis risks.

Analysis and approach

Treasury first verifies the contractual dates, cash-flow certainty, accounting designation and available counterparty limits. It then considers:

  • selling USD forward for the six-month receipt;
  • buying EUR forward for the loan repayment;
  • using a USD put option if management wants protection while retaining upside;
  • funding the euro loan with euro liabilities as a natural hedge;
  • using an interest-rate swap or cap for the repricing exposure;
  • maintaining currency-specific liquidity buffers and collateral capacity.

Suppose the six-month USD/INR spot rate is 83.20, the domestic annual rate is 6.00%, the US annual rate is 5.00%, and the simple year fraction is 0.5. The theoretical forward is:

F = 83.20 × (1 + 0.06×0.5)/(1 + 0.05×0.5)
= 83.20 × 1.03/1.025
≈ 83.6068

If the bank sells USD 10 million forward at this rate, the contracted rupee receipt is approximately:

INR ext{ receipt} = 10,000,000 × 83.6068 ≈ INR 836,068,000

This removes most exchange-rate uncertainty for the committed receipt, subject to counterparty, settlement and basis risks. If the receipt is uncertain, a put option may be more suitable, although the premium reduces the effective rupee outcome.

Outcome and learning points

The bank’s decision is not simply “hedge or do not hedge.” It is a portfolio decision involving certainty, cost, liquidity, accounting, capital and risk appetite. The hedge ratio should be documented, monitored and adjusted only under approved rules. The case demonstrates that FX risk, interest-rate risk and liquidity risk must be managed together rather than in isolated trading books.

8. Technology, data and contemporary developments

Electronic trading platforms, straight-through processing, real-time limits and centralised collateral systems have improved speed and transparency. However, automation can amplify erroneous data, stale prices or model assumptions. Artificial intelligence can support anomaly detection, cash-flow forecasting and limit surveillance, but it should not replace governance, explainability, validation or human accountability.

Contemporary treasury practice is also shaped by benchmark reform, increased collateralisation, central clearing, faster payment systems, cyber risk, sanctions controls, climate-related stress scenarios and the growth of digital currencies and tokenised settlement assets. New technology may reduce settlement time, but legal finality, operational resilience, privacy and interoperability must be established before risk claims are accepted.

9. Limitations and best practices

No hedge eliminates every risk. A forward may create opportunity cost; an option may be expensive; a swap may introduce basis and rollover risk; and a model may misstate volatility or correlations. Hedging can also create accounting volatility if documentation and effectiveness requirements are not met.

Best practices are to:

  • hedge exposures rather than speculative views unless trading is separately authorised;
  • use consistent currency, maturity and day-count conventions;
  • distinguish notional amount from market value and exposure;
  • stress-test rates, volatility, liquidity and collateral calls;
  • maintain independent valuation and confirmation;
  • document hedge purpose, ratio, instrument and exit conditions;
  • diversify counterparties and monitor wrong-way risk;
  • reconcile nostro accounts and investigate breaks promptly;
  • review behavioural assumptions and model performance;
  • report residual risk clearly to the asset-liability committee and board.

Chapter Summary

Foreign exchange markets transfer purchasing power between currencies across spot and future dates. Spot transactions settle near-term; forwards lock a future rate; swaps combine near and far exchanges; and options provide asymmetric protection in return for a premium. Forward pricing is grounded in covered interest parity, but actual market rates also reflect funding bases, credit, collateral and liquidity.

Money markets provide short-term funding and investment through deposits, bills, commercial paper, repos and related instruments. Treasury integrates FX and money-market decisions because currency funding, interest-rate repricing and liquidity are interdependent. Exposure may be transaction-based, translation-based or economic. Natural hedges and derivatives can reduce exposure, but they introduce counterparty, basis, model, collateral and rollover risks.

A sound treasury framework combines measurement, limits, stress testing, segregation of duties, independent valuation, robust settlement and clear governance. The central managerial principle is that a hedge should be judged by the risk it controls, its residual risks and its fit with the institution’s liquidity, capital, accounting and strategic objectives.
