SWIFT, Nostro-Vostro Accounts and Cross-Border Payments
Banking notes on cross-border payments: SWIFT and its BIC and MT messages, nostro, vostro, loro and mirror accounts, rupee trade settlement, LRS and UPI linkages.
By GK24 Editorial Team· Published · 5 min read

When money crosses a border it does not travel. No cash is flown from Mumbai to New York; instead two banks that hold accounts with each other adjust their books, and a message tells them what to adjust. Understanding cross-border payments therefore means understanding two separate things: the messaging layer, which is mostly SWIFT, and the account layer, which is correspondent banking through nostro and vostro accounts. Banking examinations return to this chapter again and again because the vocabulary is precise, the full forms are memorable and the Indian additions, from the rupee vostro account to the linking of UPI with foreign systems, keep it current.
What SWIFT is, and what it is not
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It was founded in 1973 as a member-owned cooperative of banks that wanted a secure, standardised substitute for the telex, it went live in 1977, and its headquarters are at La Hulpe near Brussels in Belgium. The single most important fact about it is a negative one: SWIFT does not hold accounts, does not clear and does not settle. It carries instructions. The money itself moves when banks debit and credit the accounts they maintain with one another, or when a central bank's settlement system is used. Calling SWIFT a payment system is the commonest error in an exam answer.
Every participant has a Bank Identifier Code, now called a Business Identifier Code, under the standard ISO 9362. A BIC has either eight or eleven characters: four for the institution, two for the country under ISO 3166, two for the location and, when a particular branch is meant, three more. Messages themselves follow the MT, or message type, numbering that candidates should recognise at sight.
| Message | What it does |
|---|---|
| MT 103 | Single customer credit transfer, the ordinary outward remittance |
| MT 202 | General financial institution transfer, bank to bank |
| MT 700 | Issue of a documentary credit, that is, a letter of credit |
| MT 760 | Issue of a guarantee or a standby letter of credit |
| MT 940 | Customer statement message for cash management |
| MT 799 | Free format message between banks |
The network is now migrating from these MT formats to the richer ISO 20022 standard, whose messages are called MX, and the SWIFT global payments innovation service added end-to-end tracking and same-day value to correspondent transfers. For India there is a supervisory lesson attached: the fraud uncovered at Punjab National Bank in 2018 was possible because SWIFT messages were being sent without a matching entry in the bank's core banking system, and the Reserve Bank then directed banks to integrate the two.
Nostro, vostro, loro and mirror accounts
The words come from Latin through Italian and are easiest learnt from the point of view of the bank keeping the books.
- Nostro account means our account with you. It is the account a bank maintains with a bank abroad, in that foreign country's currency. A State Bank of India account in United States dollars with a bank in New York is SBI's nostro account.
- Vostro account means your account with us. It is the account a foreign bank maintains with a domestic bank, in the domestic currency. A London bank's rupee account with a bank in Mumbai is a vostro account from the Indian bank's point of view. The same account is a nostro account in the London bank's books, so the label depends on who is speaking.
- Loro account means their account: an account of a third bank, referred to by a bank that is not a party to it.
- Mirror account is the record a bank keeps in its own books, in its home currency, of the balance in its nostro account, so that the two can be reconciled.
The arrangement as a whole is called correspondent banking, and the Indian additions to it are examinable. Under a Rupee Drawing Arrangement an Indian bank ties up with exchange houses abroad for inward personal remittances, and under the Money Transfer Service Scheme inward personal remittances are paid out through agents, subject to a ceiling of twenty-five hundred United States dollars a transaction and no more than thirty remittances a year to one beneficiary. In the other direction the Liberalised Remittance Scheme lets a resident individual remit up to two hundred and fifty thousand United States dollars in a financial year for permitted current and capital account purposes.
Settling trade in rupees
In July 2022 the Reserve Bank put in place an arrangement for invoicing, payment and settlement of exports and imports in Indian rupees. Under it a bank in India opens a Special Rupee Vostro Account for the correspondent bank of the partner country; the importer pays rupees into it and the exporter is paid out of it, with the surplus investable in Indian government securities. The purpose is to reduce dependence on hard currency, to save on conversion and, for partner countries facing payment difficulties, to keep trade going.
Beyond SWIFT: other rails and India's own systems
Several countries have built alternatives or complements to SWIFT, among them China's Cross-Border Interbank Payment System and Russia's domestic financial messaging system. India's own secure domestic messaging backbone is the Structured Financial Messaging System, developed by the Institute for Development and Research in Banking Technology and used for the Reserve Bank's RTGS and NEFT and for inland letters of credit. It is important to keep the domestic and the cross-border apart: RTGS, NEFT, IMPS, UPI, cheque truncation and the National Automated Clearing House are domestic systems run by the Reserve Bank and the National Payments Corporation of India, not international ones.
The newest layer is the direct linking of fast payment systems. NPCI International Payments Limited, set up in 2020 as a wholly owned subsidiary of the National Payments Corporation of India, takes UPI and RuPay abroad, and in February 2023 India's UPI was linked with Singapore's PayNow so that users of either system could send money to the other using a mobile number or a virtual address. In the foreign exchange market itself, settlement risk, famously named after the failure of a German bank in 1974, is reduced by paying both legs of a currency trade simultaneously through a specialised settlement bank.
Exam Point of View
Banking papers ask the full form of SWIFT and its headquarters, and above all whether SWIFT settles payments, which it does not. Expect the number of characters in a BIC, the meaning of MT 103 and MT 700, and a direct nostro versus vostro definition, often inverted to catch the careless. Current affairs questions come from the Special Rupee Vostro Account of July 2022, the Liberalised Remittance Scheme ceiling, the UPI linkage with Singapore's PayNow in February 2023, and the direction to integrate SWIFT with core banking after the 2018 fraud. The traps are confusing SWIFT with a settlement system, mixing up the domestic SFMS, RTGS and NEFT with cross-border rails, and reading nostro and vostro from the wrong bank's books.

Practice MCQs on this topic
SWIFT, used by banks for cross-border messages, stands for:
- A.Secure Worldwide International Funds Transfer
- B.Society for Worldwide Interbank Financial Telecommunication
- C.System for Wire Transfer of International Financial Transactions
- D.Standard Worldwide Interbank Funds Transfer
Show answer
Explanation
The correct answer is B, Society for Worldwide Interbank Financial Telecommunication. The word Society is the key, because SWIFT is a cooperative society owned by its member financial institutions rather than a company or a public authority. It was founded in 1973 to replace the insecure and unstandardised telex traffic between banks and went live in 1977.
Options A, C and D are invented expansions built around the same letters, and each is wrong on the most important word. None of them contains Society, so a candidate who remembers only that one word can eliminate all three at once. Two further points usually accompany this question: the headquarters are at La Hulpe near Brussels in Belgium, and SWIFT is a messaging network only, so it neither holds accounts nor settles payments. The actual movement of value happens through the accounts banks hold with each other or through a central bank's settlement system.
The headquarters of SWIFT is located in which country?
- A.Switzerland
- B.Belgium
- C.The United States of America
- D.The United Kingdom
Show answer
Explanation
The correct answer is B, Belgium. SWIFT is headquartered at La Hulpe, in the outskirts of Brussels, and it is therefore incorporated under Belgian law and supervised by a committee of central banks with the National Bank of Belgium as the lead overseer. This Belgian location matters in current affairs, because European Union decisions have at times required SWIFT to disconnect banks of particular countries.
Option A, Switzerland, is the most tempting wrong answer, because the first letter of SWIFT suggests it and because Switzerland hosts the Bank for International Settlements at Basel and many international bodies at Geneva. Option C is wrong, though the network has important operating centres in the United States and the Netherlands. Option D is wrong; London is a great financial centre but not SWIFT's seat. Remember the pairing: SWIFT in Belgium, the Bank for International Settlements in Switzerland.
Which statement about SWIFT is correct?
- A.It settles payments between banks and holds their funds
- B.It is a messaging network that carries instructions but does not itself transfer funds
- C.It is a currency exchange run by the International Monetary Fund
- D.It is the clearing house for all cross-border cheques
Show answer
Explanation
The correct answer is B, it is a messaging network that carries instructions but does not itself transfer funds. SWIFT transmits standardised, secure messages such as an instruction to pay a beneficiary or to issue a letter of credit. The value moves only when the banks involved debit and credit the accounts they maintain with one another, or when a central bank settlement system is used.
Option A is the error the question is designed to catch: SWIFT holds no customer or bank accounts and performs no settlement. Option C is wrong because the International Monetary Fund lends to member countries and surveils their economies; it runs no currency exchange of this kind, and SWIFT is a private cooperative of banks. Option D is wrong because cheque clearing is domestic and is handled in India by the Cheque Truncation System. The distinction between messaging and settlement is the single most examinable idea in this chapter.
A nostro account of an Indian bank is:
- A.A rupee account kept by a foreign bank with the Indian bank
- B.The Indian bank's foreign currency account with a bank abroad
- C.A rupee account of a resident individual for foreign travel
- D.An account of the Reserve Bank of India with the Indian bank
Show answer
Explanation
The correct answer is B, the Indian bank's foreign currency account with a bank abroad. Nostro means ours, and the full sense is our account with you. So a dollar account maintained by an Indian bank with a correspondent bank in New York, or a euro account with a bank in Frankfurt, is that Indian bank's nostro account, and it is from such an account that payments to foreign beneficiaries are made.
Option A describes a vostro account, which means your account with us, and it is the mirror image of the right answer; the same account is a nostro to one bank and a vostro to the other, so the label depends on whose books you are reading. Option C describes nothing in this vocabulary, although a resident's foreign exchange needs are met under the Liberalised Remittance Scheme. Option D is simply a current account of the central bank. A linked term is the mirror account, the home-currency record a bank keeps of its own nostro balance for reconciliation.
A rupee account maintained with an Indian bank by a bank situated abroad is called:
- A.A nostro account
- B.A vostro account
- C.A loro account
- D.An escrow account
Show answer
Explanation
The correct answer is B, a vostro account. Vostro means yours, and from the Indian bank's point of view the account is your account with us. Such accounts are held in Indian rupees, and the foreign bank uses them to make and receive payments in India. In the foreign bank's own books exactly the same account is described as a nostro account.
Option A, nostro, would be correct only from the other side of the relationship, and it is the inversion examiners most often test. Option C, loro, means their account and is used when a bank refers to an account that belongs to some third bank and not to itself. Option D, escrow, is a quite different idea: money held by a neutral party until an agreed condition is fulfilled, common in mergers and in real estate. The related Indian term is the Special Rupee Vostro Account, opened for settling foreign trade in rupees under the arrangement of July 2022.
In correspondent banking, a mirror account is:
- A.A duplicate account opened for a customer in another branch
- B.The record a bank keeps in its own books, in home currency, of its nostro balance
- C.A joint account of two banks for settlement
- D.A dormant account revived after ten years
Show answer
Explanation
The correct answer is B, the record a bank keeps in its own books, in home currency, of its nostro balance. The nostro account itself lies in the books of the foreign correspondent and is denominated in foreign currency. To track it, the bank at home maintains a parallel account in rupees, converted at the appropriate rate, and the two are reconciled regularly so that unmatched entries, missing credits or stale debits come to light quickly.
Option A describes nothing in this vocabulary; a customer's account belongs to the branch where it is opened. Option C is wrong because a nostro relationship is not a joint account; one bank is the account holder and the other is the account keeper. Option D describes an inoperative account under the rules on unclaimed deposits, an unrelated topic. Learn the four together: nostro ours with you, vostro yours with us, loro theirs, mirror our own record of the nostro.
A SWIFT Business Identifier Code or BIC consists of how many characters?
- A.Six or nine
- B.Eight or eleven
- C.Ten or twelve
- D.Exactly eleven always
Show answer
Explanation
The correct answer is B, eight or eleven. Under the standard ISO 9362 a BIC has four characters identifying the institution, two identifying the country on the ISO 3166 list, and two identifying the location, which makes eight. When a specific branch has to be named, three more characters are added, giving eleven. The eight-character form refers to the institution's primary office.
Option A is wrong on both counts and matches no part of the standard. Option C is wrong; no BIC runs to ten or twelve characters. Option D is wrong because the eleven-character form is optional, used only for a branch. Do not confuse the BIC with two other codes: the Indian Financial System Code, of eleven characters, which identifies a bank branch for domestic RTGS, NEFT and IMPS transfers, and the International Bank Account Number under ISO 13616, which identifies an account and is used in Europe but not in India.
Which SWIFT message type is used for a single customer credit transfer, the ordinary outward remittance?
- A.MT 103
- B.MT 202
- C.MT 700
- D.MT 940
Show answer
Explanation
The correct answer is A, MT 103. The MT 1 category covers customer payments, and MT 103 is the standard instruction by which a bank asks its correspondent to pay a named beneficiary a stated amount, carrying the remitter's and beneficiary's details and the charges instruction. It is the message behind almost every retail outward remittance.
Option B, MT 202, belongs to the MT 2 category of financial institution transfers and moves funds from one bank to another, often as the cover payment that accompanies an MT 103. Option C, MT 700, belongs to the MT 7 documentary credits and guarantees category and is the message by which a letter of credit is issued, with MT 760 used for a guarantee or standby credit. Option D, MT 940, is a statement message in the MT 9 cash management category. Learn the categories by their first digit; it answers a whole family of questions.
In July 2022 the Reserve Bank of India allowed the settlement of international trade in Indian rupees through which mechanism?
- A.Special Rupee Vostro Accounts
- B.Exchange Earners Foreign Currency accounts
- C.Non-Resident External accounts
- D.Resident Foreign Currency accounts
Show answer
Explanation
The correct answer is A, Special Rupee Vostro Accounts. Under the arrangement, an authorised dealer bank in India opens such an account for the correspondent bank of a partner country. Indian importers pay rupees into the account and Indian exporters are paid out of it, and the balance may be invested in Indian government securities. The aims are to cut dependence on hard currency, to save conversion cost and to keep trade flowing with countries facing payment difficulties.
Option B, an Exchange Earners Foreign Currency account, lets an Indian exporter retain part of its earnings in foreign currency instead of converting them. Option C, a Non-Resident External account, is a rupee account for a non-resident Indian, fully repatriable, meant for personal savings and not for trade settlement. Option D, a Resident Foreign Currency account, is for a returning Indian to hold foreign currency brought back. Only the first is a correspondent banking account used for settling trade.
Under the Liberalised Remittance Scheme, how much may a resident individual remit abroad in a financial year?
- A.Twenty-five thousand US dollars
- B.One hundred thousand US dollars
- C.Two hundred and fifty thousand US dollars
- D.One million US dollars
Show answer
Explanation
The correct answer is C, two hundred and fifty thousand US dollars. The Liberalised Remittance Scheme allows a resident individual, including a minor, to remit up to that amount in a financial year for any permitted current account purpose such as travel, education, medical treatment, gifts and maintenance of relatives, and for permitted capital account purposes such as buying property or shares abroad. The limit was raised to this figure in 2015.
Option A, twenty-five thousand dollars, was the limit when the scheme was introduced in 2004, so it is correct only historically. Option B, one hundred thousand dollars, was an intermediate limit, and the figure was also reduced to seventy-five thousand for a short period in 2013 before being raised again. Option D, one million dollars, is the limit under a separate facility, the remittance of assets by a non-resident Indian out of a Non-Resident Ordinary account or inherited property, in a financial year. The scheme does not permit remittances for lottery, margin trading or to countries identified as non-cooperative.
India's own secure financial messaging backbone, used for RTGS, NEFT and inland letters of credit, is:
- A.The Structured Financial Messaging System
- B.The National Automated Clearing House
- C.The Cheque Truncation System
- D.The Centralised Payment System
Show answer
Explanation
The correct answer is A, the Structured Financial Messaging System. Developed by the Institute for Development and Research in Banking Technology at Hyderabad and built on the INFINET network of the banking sector, it carries the secure, standardised messages behind the Reserve Bank's Real Time Gross Settlement and National Electronic Funds Transfer, and is also used for inland letters of credit between Indian banks. It is in effect the domestic counterpart of SWIFT.
Option B, the National Automated Clearing House, is a bulk payment service of the National Payments Corporation of India for salaries, dividends, subsidies and recurring debits, not a messaging standard. Option C, the Cheque Truncation System, clears cheques by exchanging their electronic images instead of moving paper. Option D is a loose description and not the name of a system. The lesson to carry away is that SWIFT is for cross-border messages, while this system, RTGS, NEFT, IMPS and UPI are domestic.
In February 2023, India's Unified Payments Interface was linked with the fast payment system of which country?
- A.The United Arab Emirates
- B.Singapore
- C.Nepal
- D.Bhutan
Show answer
Explanation
The correct answer is B, Singapore. The linkage joined India's Unified Payments Interface with Singapore's PayNow, so that users of either system could send money across the border using a mobile number or a virtual payment address rather than full bank details. It was the first such linkage of two national fast payment systems involving India, and the work was done through NPCI International Payments Limited, a subsidiary set up in 2020 to take UPI and RuPay abroad.
Option A is wrong as to this event, although the United Arab Emirates is among the countries where RuPay and UPI acceptance has been extended. Option C, Nepal, and option D, Bhutan, are both countries where Indian payment instruments have been made usable, Bhutan notably accepting both RuPay and UPI; but neither involved a two-way linking of fast payment systems in February 2023. Keep the February 2023 UPI and PayNow pairing as the standard fact for this question.
Frequently Asked Questions
Does money actually move through SWIFT?
No. SWIFT carries standardised, secure messages such as instructions to pay or to issue a letter of credit. The value itself moves when banks debit and credit the accounts they hold with one another, that is, their nostro and vostro accounts, or when a central bank's settlement system is used. Treating SWIFT as a payment system is the commonest error.
What is the difference between a nostro and a vostro account?
The two words describe the same account from opposite sides. Nostro means our account with you, held by a bank with a correspondent abroad in that country's currency. Vostro means your account with us, held by a foreign bank with a domestic bank in the domestic currency. Whether an account is a nostro or a vostro therefore depends on whose books are being read.
What is a Special Rupee Vostro Account?
It is the account an Indian bank opens for the correspondent bank of a partner country so that exports and imports can be invoiced, paid for and settled in Indian rupees, under the arrangement the Reserve Bank put in place in July 2022. Indian importers pay rupees into it, exporters are paid out of it, and the balance may be invested in Indian government securities.
How much can a resident individual send abroad in a year?
Up to two hundred and fifty thousand United States dollars in a financial year under the Liberalised Remittance Scheme, for permitted current account purposes such as travel, education, medical treatment and gifts, and for permitted capital account purposes such as buying property or shares abroad. Remittances for lottery, margin trading and certain countries are not allowed.
Is SWIFT used for payments inside India?
No. Domestic transfers use the Reserve Bank's RTGS and NEFT, the National Payments Corporation's IMPS, UPI and National Automated Clearing House, and the Cheque Truncation System for cheques. The secure messaging behind RTGS and NEFT is the Structured Financial Messaging System developed by IDRBT, which is the domestic counterpart of SWIFT.
What lesson did the 2018 Punjab National Bank fraud teach about SWIFT?
That a messaging terminal left outside the bank's accounting system is dangerous. Instruments were issued over SWIFT without any matching entry in the core banking system, so the liability stayed invisible for years. The Reserve Bank then directed banks to integrate their SWIFT operations with their core banking systems and to tighten controls over message creation and authorisation.
