Cross-Currency Liquidity and Overseas Operations - Article

Introduction

A bank operating internationally may have liquidity in several:

• currencies;

• countries;

• branches;

• subsidiaries; and

• legal entities.

Its total balance sheet may appear liquid, but the liquidity may not be available in the currency, country or entity where payment is due.

For example, a bank may have:

• surplus Indian rupees in India; but

• a large US-dollar payment obligation at its overseas branch.

The bank may plan to convert rupees into dollars through the FX swap market. However, during severe stress:

• dollar funding may become scarce;

• swap-market liquidity may deteriorate;

• counterparties may reduce limits; or

• legal restrictions may prevent movement of funds across jurisdictions.

This creates cross-currency and cross-border liquidity risk.

The current 2026 IIBF BFM syllabus specifically covers Overseas Operations of Indian Banks' Branches and Subsidiaries, Liquidity Across Currencies, MIS, reporting and internal controls under Liquidity Risk Management.

For the current Indian regulatory position, RBI issued the Reserve Bank of India (Commercial Banks – Asset Liability Management) Directions, 2025 on November 28, 2025. These Directions came into effect from the date of issue and contain detailed requirements for liquidity across currencies and overseas operations.

The central CAIIB principle is:

Liquidity available somewhere in the banking group is not automatically liquidity available everywhere in the group.

Learning Objectives

After studying this topic, you should be able to:

• explain cross-currency liquidity risk;

• distinguish aggregate liquidity from currency-specific liquidity;

• understand the role and limitations of FX swaps;

• explain transferability risk across currencies and legal entities;

• understand liquidity management of overseas branches and subsidiaries;

• identify important current RBI requirements; and

• avoid common CAIIB traps involving group and foreign-currency liquidity.

What Is Cross-Currency Liquidity Risk?

Cross-currency liquidity risk arises when a bank has a cash requirement in one currency but its available liquidity is mainly in another currency.

Example

A bank has:

• surplus ₹ liquidity; and

• a USD 100 million payment due overseas.

It may normally obtain dollars by:

• borrowing in the dollar market; or

• entering into an INR/USD swap.

If those markets remain liquid, the position may be manageable.

But if the dollar or FX swap market becomes disrupted, the bank may be unable to obtain dollars at the required time or reasonable cost.

Therefore:

Aggregate cash surplus ≠ adequate liquidity in each currency

Basel requires banks to assess their ability to:

• raise funds in foreign-currency markets;

• obtain foreign-currency backup facilities;

• transfer surplus liquidity from one currency to another; and

• convert currencies during stress, including possible impairment or closure of FX swap markets.

Why Currency Matters in Liquidity Management

A payment obligation must generally be settled in the required currency.

If a bank owes dollars, holding rupees does not by itself settle the dollar obligation.

The bank must be able to:

• obtain dollars directly; or

• convert another currency into dollars.

This creates dependence on:

• FX markets;

• FX swaps;

• correspondent banks;

• funding counterparties; and

• operational settlement arrangements.

Current RBI Requirement

Under the 2025 ALM Directions, a bank must maintain a measurement, monitoring and control system for liquidity positions in the major currencies in which it is active.

RBI also requires a separate analysis of strategy for each major currency, taking account of stress-test outcomes.

The bank's assessment should consider:

1. ability to raise funds in foreign-currency markets;

2. foreign-currency backup facilities available domestically;

3. ability to transfer liquidity between currencies, jurisdictions and legal entities; and

4. convertibility of currencies, including possible disruption or closure of FX swap markets.

Cross-Currency Funding

Banks may fund assets in one currency using liabilities in another currency.

Example 1

A bank has dollar loans but obtains most of its funding in rupees.

It uses an FX swap to convert rupee funding into dollars.

Example 2

A foreign branch receives dollar deposits but finances assets denominated in another currency.

These arrangements may reduce funding cost or improve flexibility.

However, they create additional dependencies.

Main Cross-Currency Risks

FX Swap Market Risk

The swap market may:

• become illiquid;

• become expensive;

• have wider bid-offer spreads; or

• temporarily become unavailable.

Rollover Risk

A short-term FX swap may mature before the underlying asset.

The bank must continuously renew the swap.

Counterparty Risk

A counterparty may:

• reduce limits;

• refuse renewal; or

• demand more collateral.

Currency Convertibility Risk

Some currencies may become difficult to exchange during stress.

Settlement and Time-Zone Risk

Payments in different currencies may settle:

• in different financial centres;

• through different payment systems; and

• at different times of day.

This can create intraday liquidity requirements.

FX Swap Dependence

FX swaps are important tools for managing currency liquidity.

However, a bank should not assume that a deep and liquid FX swap market will always remain available.

Basel specifically states that banks should critically assess the risk that their ability to swap currencies may erode rapidly under stressed conditions.

Normal Situation

Bank has INR surplus → FX swap → obtains USD → meets USD obligation.

Stress Situation

Bank has INR surplus → FX swap market disrupted → USD cannot be obtained easily.

The bank is therefore liquid in rupees but stressed in dollars.

Transferability of Liquidity

Liquidity may also be trapped because funds cannot move freely between:

• countries;

• branches;

• subsidiaries;

• legal entities; or

• currencies.

Basel requires banks to consider legal, regulatory and operational restrictions when managing liquidity across entities and jurisdictions.

Potential constraints include:

• host-country regulations;

• exchange controls;

• tax restrictions;

• capital requirements;

• legal restrictions;

• collateral requirements;

• internal limits;

• operational delays; and

• different time zones.

Example

A subsidiary has excess cash.

Another entity within the same banking group faces a liquidity shortage.

If regulations prevent the subsidiary from transferring those funds, the group-level surplus cannot solve the entity-level deficit.

Therefore:

Group liquidity surplus ≠ transferable liquidity

Overseas Branch vs Overseas Subsidiary

This distinction is important.

Overseas Branch

A branch is part of the same legal banking entity as its Head Office.

Overseas Subsidiary

A subsidiary is a separate legal entity owned or controlled by the banking group.

This difference affects:

• regulatory treatment;

• transferability of liquidity;

• reliance on Head Office; and

• responsibility during stress.

Basel states that liquidity should be monitored at the level of:

• individual legal entities;

• foreign branches;

• subsidiaries; and

• the consolidated group.

Current RBI Framework for Overseas Operations

RBI's 2025 ALM Directions require a bank's liquidity policy to contain detailed guidelines for overseas branches and subsidiaries to manage operational liquidity continuously.

Short-term operational liquidity is expected to be delegated to local management as part of the local treasury function.

At the same time, the bank must maintain centralised oversight of the total overseas liquidity position.

This creates a combination of:

Local operational management + Group-level oversight

Overseas Structural Liquidity Statement

RBI requires a Structural Liquidity Statement (SLS) for overseas operations to be:

• prepared country-wise on a daily basis; and

• reported to RBI on a monthly basis.

Figures for overseas subsidiaries and joint ventures are also required on a stand-alone basis under the prescribed framework.

Short-Term Mismatch Limits

The current RBI limits for net cumulative negative mismatches also apply to overseas operations country-wise:

These limits are percentages of cumulative cash outflows in the respective buckets.

Broad RBI Norms for Overseas Liquidity

The 2025 Directions contain additional specific requirements for overseas operations.

Long-Term Funding

A bank should broaden its long-term resources and funding capacity in line with long-term assets and commitments.

RBI currently prescribes that:

• long-term resources should not fall below 70% of long-term assets; and

• long- and medium-term resources together should not fall below 80% of long- and medium-term assets.

For this purpose:

• Short-term: maturity within 6 months;

• Medium-term: 6 months or longer but within 3 years;

• Long-term: 3 years or longer.

Currency-Wise Application

These controls are applied currency-wise to currencies that individually constitute 10% or more of the bank's consolidated overseas balance sheet.

RBI does not permit netting of inter-currency positions and maturity gaps for these controls.

Why Inter-Currency Netting Can Be Misleading

Suppose an overseas operation has:

• USD liquidity deficit; and

• EUR liquidity surplus.

At an aggregate level, these may appear to offset each other.

But the actual position depends on whether:

• EUR can be converted into USD;

• the FX market remains open;

• sufficient counterparties exist;

• transfer can occur on time; and

• legal or regulatory restrictions permit it.

During stress, these assumptions may fail.

This is why currency-specific analysis is necessary.

Centralised Oversight of Overseas Liquidity

Under RBI's current framework, monitoring of structural maturity mismatches in the overseas sector should be centralised in the bank's International Division, on a consolidated and currency-wise basis.

The International Division must review the structural maturity mismatch position quarterly and submit the review to top management.

The bank must also maintain group-level oversight even where local liquidity management is decentralised.

Basel follows the same broad principle: the group should understand its aggregate position while monitoring individual branches and entities separately.

Home-Country vs Host-Country Requirements

A bank operating overseas may face requirements from:

• its home-country regulator; and

• the regulator of the country where the branch or subsidiary operates.

Under RBI's current Directions, Indian banks' branches and subsidiaries abroad must manage liquidity according to the host or home country requirements, whichever is more stringent.

This is a high-value CAIIB distinction.

The bank cannot simply apply the less demanding framework.

Basel also recognises that national liquidity parameters can differ and that host-country treatment may be relevant to entities operating locally.

Self-Sufficiency of Overseas Operations

RBI expects overseas branches and subsidiaries to be sufficiently self-reliant to withstand severe but plausible liquidity stress scenarios.

However, an important distinction applies during extreme stress.

Overseas Branch of an Indian Bank

An overseas branch may rely on liquidity support from Head Office in extreme stress.

Overseas Subsidiary

An overseas subsidiary is expected to remain self-reliant.

This reflects the subsidiary's position as a separate legal entity.

The presence of group support should therefore not automatically be assumed when assessing subsidiary liquidity.

Foreign Banks Operating in India

RBI also requires a foreign bank operating in India to be self-reliant in liquidity management.

In extreme stress, it may rely on support from its parent or Head Office.

However, its contingency planning must consider:

• restrictions on transfer of funds;

• possible time delay;

• market-wide or group-wide stress; and

• possibility that expected Head Office funds may not actually be available.

The broader principle is:

Expected intragroup support should be treated realistically, not as guaranteed liquidity.

Significant Currency and Intraday Liquidity

Cross-currency considerations also apply to intraday liquidity.

RBI's 2025 Directions state that where a bank manages intraday liquidity on a cross-currency basis, it should consider:

• closure of currency swap markets;

• operational problems in swap markets; and

• simultaneous stress in multiple payment systems.

Where RBI permits aggregated cross-currency reporting based on demonstrated ability to move funds with minimal delay even under acute stress, the bank must still report liquidity at the level of each significant currency.

For this intraday monitoring purpose, a currency is significant where liabilities denominated in that currency equal 5% or more of the bank's total liabilities.

Do not confuse this 5% threshold with the separate 10% consolidated overseas balance-sheet threshold used for certain overseas maturity controls.

Stress Testing Cross-Currency Liquidity

Cross-currency liquidity assumptions should be challenged under stress.

A bank may test:

• closure of FX swap markets;

• reduced rollover of foreign-currency borrowing;

• loss of correspondent-bank lines;

• deposit withdrawal in one currency;

• sharp increase in collateral requirements;

• restrictions on cross-border transfers; or

• simultaneous stress in several currencies.

Basel specifically requires liquidity stress testing to consider FX convertibility, access to FX markets and the ability to transfer liquidity across entities and borders.

Example

A bank assumes:

USD shortfall → EUR surplus → EUR/USD swap → USD obtained

A useful stress test should also examine:

USD shortfall → EUR surplus → swap market impaired → conversion delayed or unavailable

The second scenario reveals the true cross-currency vulnerability.

Practical Banking Application

Consider an Indian bank with branches in Singapore and London.

The Singapore branch has excess USD liquidity.

The London branch faces a GBP funding shortage.

At the consolidated level, the bank appears liquid.

Before assuming that Singapore's surplus solves London's problem, management must ask:

• Can the funds legally be transferred?

• Is the required currency conversion available?

• What is the transfer time?

• Are there local liquidity requirements?

• Would Singapore remain sufficiently liquid after the transfer?

• Could both locations experience stress simultaneously?

• Does the group CFP recognise these constraints?

Only after answering these questions can the bank determine whether the apparent group liquidity is actually usable.

Cross-Currency Liquidity vs FX Market Risk

These risks are related but different.

A properly hedged exchange-rate position can still face liquidity risk if the hedge requires collateral or cannot be rolled over.

CAIIB Exam Focus

Remember these high-value concepts:

• Aggregate liquidity and currency-specific liquidity are different.

• Foreign-currency liquidity should be measured and monitored separately where material.

• Cross-currency liquidity depends on access to FX and swap markets.

• FX swap availability can deteriorate sharply during stress.

• Currency liquidity should not be assumed freely transferable across jurisdictions.

• Legal entities, branches and subsidiaries require separate liquidity monitoring.

• Group-wide liquidity should also be aggregated.

• RBI's 2025 ALM Directions are currently applicable from November 28, 2025.

• Overseas SLS is prepared country-wise daily and reported to RBI monthly.

• RBI's 5%, 10%, 15% and 20% short-term cumulative mismatch limits also apply country-wise to overseas operations.

• Current overseas norms require long-term resources of at least 70% of long-term assets.

• Long- plus medium-term resources must be at least 80% of corresponding long- and medium-term assets.

• For these overseas controls, specified currency-wise monitoring applies to currencies constituting at least 10% of consolidated overseas balance sheet.

• Inter-currency netting of these positions and maturity gaps is not permitted.

• Overseas liquidity management combines local operational management with centralised group oversight.

• Indian overseas branches and subsidiaries follow home or host requirements, whichever is more stringent.

• Overseas branches may rely on Head Office during extreme stress.

• Overseas subsidiaries are expected to be self-reliant.

• Significant-currency intraday reporting uses a separate 5% of total liabilities threshold.

• Expected Head Office support should be tested for legal, operational and timing constraints.

• Cross-currency liquidity risk is different from FX market risk.

Common Exam Traps

Trap 1: “If the banking group has surplus liquidity overall, every overseas entity is adequately liquid.”

Incorrect. Funds may be trapped by currency, legal-entity or jurisdictional restrictions.

Trap 2: “A rupee surplus automatically covers a dollar shortfall.”

Incorrect. Currency conversion and FX-market access are required.

Trap 3: “An FX swap completely removes cross-currency liquidity risk.”

Incorrect. The swap may need rollover and the market can become impaired during stress.

Trap 4: “Foreign-currency liquidity and foreign-exchange market risk are the same.”

Incorrect. Liquidity concerns obtaining currency on time; market risk concerns adverse exchange-rate movements.

Trap 5: “Overseas branches and subsidiaries are treated identically during extreme stress.”

Incorrect. RBI allows an overseas branch of an Indian bank to rely on Head Office support in extreme stress, while its overseas subsidiary is expected to remain self-reliant.

Trap 6: “Indian banks abroad need follow only RBI's requirements.”

Incorrect. They must follow home or host liquidity requirements, whichever is more stringent.

Trap 7: “A liquidity surplus in EUR can always be netted against a USD deficit for RBI overseas maturity controls.”

Incorrect. RBI's specified overseas controls are applied currency-wise and inter-currency netting is not permitted.

Trap 8: “The 5% significant-currency threshold and 10% overseas currency threshold are the same rule.”

Incorrect. They apply in different regulatory contexts.

Trap 9: “Decentralised overseas liquidity management means Head Office need not monitor overseas liquidity.”

Incorrect. RBI requires centralised group-level oversight even where operational management is decentralised.

Trap 10: “Expected Head Office funding can always be treated as immediately available liquidity.”

Incorrect. Transfer restrictions, time lags and group-wide stress may prevent the funds from arriving when required.

Memory Technique

Remember C–E–T–S:

C — Currency: Is liquidity available in the required currency? E — Entity: Which branch or subsidiary actually holds it? T — Transferability: Can funds and collateral legally and operationally move? S — Stress: Will the conversion or transfer still work during stress?

For overseas operations, remember:

Local liquidity → Central oversight → Currency-wise control → Stress self-sufficiency

The central CAIIB principle is:

Liquidity is useful only when it is available in the right currency, at the right entity, in the right jurisdiction and at the required time.
