Week 9: The Foreign Exchange Market — Structure, Participants, Trading Sessions & FX Quotations
Learning Objectives
By the end of this session, students will be able to:
Describe the structure, size, and functioning of the global foreign exchange market — its OTC nature, 24-hour trading cycle, major trading centres, and the roles of its diverse participants from dealer banks to central banks to retail traders.
Identify major currency pairs, trading conventions, and the three global trading sessions (Asian, European, North American), and explain how session overlaps create periods of maximum liquidity and volatility.
Distinguish between direct and indirect quotations, American and European terms, and interpret two-way (bid-ask) quotes — computing the spread in both absolute and percentage terms and explaining the factors that determine its width.
Interpret spot FX quotations as they appear on trading screens (Bloomberg, Reuters), translate between quotation conventions, and calculate the cost of currency conversion for corporate transactions.
4-Hour Session Planner
This session opens Unit 3 by immersing students in the operational reality of the FX market — the largest financial market in the world.
Opening Hook: "What Happens When You Swipe Your Card in Paris?"
15 minStudents trace the journey of a single Visa card transaction: an Indian tourist in Paris buys a coffee for EUR 5 — INR is debited. What happens in the 2–3 seconds between the card swipe and the INR amount appearing? This micro-story reveals the FX market's infrastructure: the merchant acquirer, the card network, the interbank FX market, and the final INR/EUR conversion rate.
Section 1: The FX Market — Scale, Structure & Uniqueness
35 minThe FX market in numbers: USD 7.5 trillion daily turnover (BIS 2022). The OTC structure — no central exchange, no single location. The 24-hour trading cycle. The five layers of the market: interdealer, dealer-client, brokered, exchange-traded, and retail.
Section 2: The Participants — Who Trades, and Why?
30 minThe cast of characters: dealer banks (market makers), central banks, corporations, institutional investors and hedge funds, retail traders, and brokers/electronic platforms. Each participant's motives, volumes, and impact on price dynamics.
Section 3: Currency Pairs, Trading Sessions & Electronic Platforms
30 minMajor, minor, and exotic pairs. The three-session global day: Asian, European, North American — and the critical London/NY overlap. Electronic trading systems: EBS, Reuters Matching, Bloomberg FXGO, and the rise of algorithmic trading.
CQ Box 1: Market Structure Analysis
10 min"If the FX market is the world's largest and most liquid, why does the INR market sometimes experience sharp, discontinuous moves during Indian trading hours? What structural features explain these episodic liquidity gaps?"
Section 4: FX Quotations — Direct, Indirect, American & European Terms
30 minThe fundamental building block: how prices are quoted. Direct vs indirect quotation. American vs European terms. The base currency / quote currency structure. Translating between quotation conventions.
Section 5: Two-Way Quotes — Bid, Ask, and the Spread
25 minThe dealer's two-way price: bid and ask. Computing the spread — absolute and percentage. What determines the spread: liquidity, volatility, dealer inventory, and the currency pair. The spread as the transaction cost of the FX market.
In-Lecture Quiz (4 Questions)

20 minFaculty reviews 12 key terms. Exit Ticket with quotation computation exercises. Preview of Week 10 (Spot & Forward Rates).
"You're an Indian tourist in Paris. You buy a cafe creme for EUR 5. You tap your Indian Visa card. Two seconds later, INR 453 is debited from your account. What just happened — and who took the other side of that trade?"
Making the FX Market Tangible
Key teaching points: (1) Dealer spread: The rate applied to your card (EUR/INR ~90.60) is worse than the interbank rate (~90.10). The difference is the retail spread — how Visa and your bank earn revenue. (2) Netting: Visa nets millions of transactions across currencies and trades only the net exposure. Netting is the operational backbone of the FX market. (3) Infrastructure: The transaction involves the card network, SWIFT messaging, correspondent banking, and CLS settlement. The FX market is a vast physical infrastructure processing over USD 7.5 trillion per day.
1. The Foreign Exchange Market — Scale, Structure & Uniqueness
1.1 What Is the FX Market?
The Foreign Exchange (FX) Market is the global marketplace in which currencies are bought and sold. It is not a single physical location but a decentralised, over-the-counter (OTC) network of dealer banks, brokers, electronic trading platforms, central banks, corporations, and investors — conducting currency transactions 24 hours a day across every time zone. It is the largest, most liquid, and most globally integrated financial market that has ever existed.
• OTC (Over-the-Counter): No central exchange. Trades are negotiated bilaterally between counterparties. There is no single "market price" at any moment — multiple, slightly different prices are quoted by different dealers.
• 24-Hour Trading: The market opens in Wellington/Sydney on Monday morning (Sunday evening GMT) and trades continuously until New York closes on Friday evening.
• Unparallelled Liquidity: Daily turnover of USD 7.5 trillion (BIS Triennial Survey, April 2022) — exceeding the annual GDP of all but the largest countries, every single day. The daily FX turnover exceeds total annual global trade in goods and services (~USD 25 trillion).
• Geographically Dispersed but Electronically Integrated: Trading is concentrated in five centres — London (~38% of global turnover), New York (~19%), Singapore (~9%), Hong Kong (~7%), and Tokyo (~5%) — but electronic trading means geographic location is increasingly irrelevant for price discovery.
1.2 The BIS Triennial Survey — The FX Market in Numbers
| Metric | 2019 | 2022 | Change |
|---|---|---|---|
| Global daily turnover | USD 6.6 trillion | USD 7.5 trillion | +14% |
| Spot transactions | USD 2.0T (30%) | USD 2.1T (28%) | +5% |
| FX swaps | USD 3.2T (49%) | USD 3.8T (51%) | +19% |
| Forwards | USD 1.0T (15%) | USD 1.2T (16%) | +20% |
| USD/INR daily turnover | ~USD 50B | ~USD 100B | +100% |
| Most traded pair | EUR/USD (24%) | EUR/USD (22.7%) | — |
| USD involvement | 88% of all trades | 88% of all trades | Unchanged |
Critical observations: (a) The USD is on one side of 88% of all FX transactions — the dollar is the "vehicle currency" through which most non-USD currency pairs are traded. (b) Spot transactions account for only 28% of turnover — the vast majority of FX trading is in derivatives (swaps, forwards). The FX market is primarily a market for managing risk and funding, not for exchanging currency for trade settlement. (c) INR turnover has doubled since 2019 — reflecting the progressive internationalisation of the rupee despite its limited convertibility.
1.3 The OTC Structure — Five Layers of the Market
- The Interdealer Market (Layer 1 — Core): Where the largest dealer banks trade with each other — either bilaterally or through voice brokers and electronic platforms (EBS, Reuters). This is the price-discovery engine. The top 5 dealer banks (JP Morgan, UBS, XTX Markets, Deutsche Bank, Citi) account for ~35–40% of global FX volume.
- The Dealer-Client Market (Layer 2): Dealer banks quote two-way prices to clients — corporations, institutional investors, central banks. The dealer-client rate includes a spread over the interdealer rate. For major pairs, the client spread might be 1–2 pips; for exotic pairs, 20–50 pips; for large MNCs, negotiable.
- The Brokered Market (Layer 3): Voice brokers and electronic brokers match buyers and sellers without taking principal positions. Brokered trades are anonymous — critical for large trades where revealing the counterparty would move the price. Electronic brokers (EBS, Reuters) have largely displaced voice brokers for major currencies.
- The Exchange-Traded Market (Layer 4): Currency futures and options on organised exchanges — CME, SGX, BSE/NSE (currency derivatives segment). Standardised, centrally cleared, transparent. Accounts for only ~5–8% of total FX turnover but provides the primary source of public price data.
- The Retail Market (Layer 5): Individuals and small businesses trading through retail forex brokers, money changers, and bank FX portals. Retail spreads are much wider (airport kiosks may quote 3–5% over interbank). The retail segment has grown rapidly with fintech FX providers (Wise, Revolut).
2. The Participants — Who Trades, and Why?
| Participant | Primary Motive | Typical Size | Indian Context |
|---|---|---|---|
| Dealer Banks | Profit from bid-ask spread and proprietary positioning. Provide liquidity. | USD 5–100M per clip | SBI, HDFC Bank, ICICI, Axis, foreign banks (StanChart, Citi, HSBC). Top 10 dominate INR interbank. |
| Central Banks | Manage exchange rate, accumulate/deploy reserves. Policy-motivated, not profit. | USD 100M–5B per episode | The RBI is a perpetual presence — buying USD to prevent appreciation, selling to smooth depreciation. |
| Corporations (MNCs) | Hedge commercial exposures (exports, imports, debt service). | USD 500K–100M | Infosys (sell USD), IOC (buy USD), Tata Motors (multi-currency). Aggregate hedging is a significant INR driver. |
| Institutional Investors & Hedge Funds | Cross-border portfolio investment, speculation (macro funds). | USD 10M–500M | FPIs are the dominant marginal price-setter in INR during global risk-on/risk-off episodes. |
| Retail Traders & SMEs | Speculation, tourism, small payments, remittances. | USD 100–100K | NRI remittances — USD 120B+ annually — largest single retail/semi-retail flow into India. |
| Brokers & Platforms | Match buyers and sellers; no principal positions. | Facilitate only | NDS-OM, CCIL for INR; EBS, Reuters globally. Algo/HFT now ~40–50% of spot FX. |
3. Currency Pairs, Trading Sessions & Electronic Platforms
3.1 Major, Minor, and Exotic Currency Pairs
- Major Pairs (G10): All involve USD. EUR/USD (~23%), USD/JPY (~13%), GBP/USD (~9%), USD/CHF, AUD/USD, USD/CAD, NZD/USD. Spreads: 0.1–2 pips.
- Minor Pairs / Crosses: No USD: EUR/GBP, EUR/JPY, GBP/JPY. Spreads: 1–5 pips.
- EM and Exotic Pairs: USD/INR, USD/BRL, USD/ZAR, USD/TRY. Spreads: 2–20 pips for liquid EM; 50–200+ for exotics. Liquidity can evaporate rapidly during stress.
3.2 The Global Trading Day
| Session | Centres | GMT | IST Overlap | Characteristic |
|---|---|---|---|---|
| Asian | Wellington, Sydney, Tokyo, Singapore, HK | 22:00–08:00 | 3:30 AM–1:30 PM | Moderate liquidity. JPY, AUD, NZD active. INR trading begins ~9 AM IST. |
| European | London, Frankfurt, Zurich, Paris | 07:00–16:00 | 12:30 PM–9:30 PM | Highest liquidity. London = 38% of global. EUR, GBP, CHF active. |
| North American | New York, Toronto, Chicago | 12:00–20:00 | 5:30 PM–1:30 AM | High liquidity. Major US data releases at 8:30 AM / 2:00 PM ET — peak volatility. |
| London/NY Overlap | — | 12:00–16:00 | 5:30 PM–9:30 PM IST | Maximum liquidity. Tightest spreads. Best window for large corporate FX execution. |
IFM Implication: An Indian firm converting USD 50M to INR should execute during the London/NY overlap (5:30–9:30 PM IST) for tightest spreads and deepest liquidity. For non-time-critical conversions, the treasurer can "work the order" over several days during the most liquid windows.
3.3 Electronic Trading Platforms
- EBS (CME Group): Dominant interdealer platform for EUR/USD, USD/JPY, EUR/JPY. Central limit order book.
- Reuters Matching (Refinitiv/LSEG): Dominant for GBP/USD, AUD/USD, EM pairs. The WM/Reuters Fix (4:00 PM London) is the most-used corporate FX benchmark globally.
- Bloomberg FXGO: Multi-bank RFQ platform. Client requests quotes from multiple dealers simultaneously and selects the best.
- Multi-Dealer Platforms: FXall, 360T, FX Connect — aggregate quotes, increasing competition and compressing spreads.
- Algorithmic / HFT: Algos now ~40–50% of spot FX volume. Provide liquidity (narrowing spreads) but can withdraw abruptly (flash crashes — e.g., GBP flash crash Oct 2016, −9% in 2 minutes).
4. FX Quotations — Direct, Indirect, American & European Terms
4.1 The Base Currency / Quote Currency Structure
Every FX quote: Base Currency / Quote Currency = Rate. The rate tells you how many units of the quote currency are needed to buy one unit of the base currency. Example: EUR/USD = 1.0850 means 1 EUR = 1.0850 USD.
4.2 Direct vs. Indirect Quotation
- Direct (Price) Quotation: Domestic currency per unit of foreign currency. From India: INR 83/USD. "How many rupees to buy one dollar?"
- Indirect (Volume) Quotation: Foreign currency per unit of domestic currency. From India: USD 0.01205/INR. "How many dollars does one rupee buy?"
- Relationship: Direct = 1 / Indirect. INR 83/USD → indirect = 1/83 = USD 0.01205/INR.
4.3 American Terms vs. European Terms
- American Terms: USD is the base (USD/XXX). USD/JPY = 150, USD/CAD = 1.36, USD/INR = 83. A rise means USD appreciated.
- European Terms: USD is the quote (XXX/USD). EUR/USD = 1.0850, GBP/USD = 1.2650, AUD/USD = 0.66. A rise means USD depreciated.
- Convention: EUR, GBP, AUD, NZD are quoted in European terms. All others in American terms. This is universal — a trader in Tokyo, London, and NY all quote EUR/USD identically.
4.4 Worked Example — Converting Between Conventions
A London dealer quotes EUR/USD = 1.0850. What is USD/EUR? USD/EUR = 1 / 1.0850 = 0.9217. One USD buys 0.9217 euros. This is American terms for the EUR (USD is the base).
A Mumbai dealer quotes USD/INR = 83.00 (American terms = direct from India). What is INR/USD? INR/USD = 1 / 83.00 = USD 0.01205/INR. This is indirect from India's perspective (European terms for the USD).
5. Two-Way Quotes — Bid, Ask, and the Spread
5.1 The Dealer's Two-Way Price
In the professional FX market, dealers quote two-way prices: a bid (the price at which the dealer buys the base currency) and an ask/offer (the price at which the dealer sells the base currency). The bid is always lower than the ask — the dealer buys low and sells high, earning the spread.
• Bid = 1.0848: Dealer buys EUR (sells USD) at this price. If you want to sell EUR, you transact at the bid — 1.0848.
• Ask = 1.0852: Dealer sells EUR (buys USD) at this price. If you want to buy EUR, you transact at the ask — 1.0852.
Customer's rule: You always buy at the higher price (ask) and sell at the lower price (bid). The spread is your transaction cost.
5.2 Computing the Spread
Absolute Spread: Ask − Bid. For EUR/USD 1.0848/1.0852: 1.0852 − 1.0848 = 0.0004 (4 pips).
Percentage Spread: (Ask − Bid) / Ask × 100. For EUR/USD: 0.0004 / 1.0852 × 100 ≈ 0.037%.
Numerical Example — USD/INR: Dealer quotes USD/INR = 82.96 / 83.04.
Absolute spread = 83.04 − 82.96 = INR 0.08 (8 paise). Percentage spread = 0.08 / 83.04 ≈ 0.096%.
Corporate transaction: Converting USD 1M: Ask cost = 1M × 83.04 = INR 8,30,40,000. Bid proceeds = 1M × 82.96 = INR 8,29,60,000. Round-trip cost (buy and immediately sell) = INR 80,000 — purely from the spread.
5.3 What Determines the Spread?
- Currency liquidity: EUR/USD: 0.1–2 pips. USD/INR interbank: 2–8 paise. Exotics: 50–200+ pips.
- Market volatility: Spreads widen sharply during stress (FOMC, geopolitical shocks). 2013 Taper Tantrum: USD/INR spreads widened to 15–25 paise.
- Transaction size: Standard interbank size (USD 5–10M): tightest spread. Very large (USD 500M): wider spread (dealer must hedge). Very small (USD 50K): wider spread (fixed processing costs proportionally higher).
- Dealer inventory: A dealer long the base currency lowers both bid and ask to discourage further sales to them. A dealer short raises both.
- Time of day: Tightest during London/NY overlap. Widest during Asian night. For INR: tightest during Indian hours (9 AM–5 PM IST), wider after hours when trading shifts to offshore NDF.
The BIS 2022 survey reports USD/INR daily turnover at approximately USD 100 billion — ranking among the top 15 most-traded pairs globally. Yet INR market participants frequently complain about "liquidity gaps" — moments when the INR moves 50 paise or more in minutes with spreads widening sharply. This almost never happens to EUR/USD.
(a) What structural features of the INR market explain these episodic liquidity gaps despite respectable turnover? Consider: number of active market makers, order-book depth, the RBI's presence, and onshore/offshore segmentation.
(b) The "RBI factor": How does the RBI's asymmetric intervention shape market-makers' behaviour? If a dealer knows the RBI is likely to buy USD when the rupee strengthens below 82, how does that affect the dealer's willingness to quote tight spreads at 81.90?
(c) Offshore NDF market: A substantial portion of INR trading occurs in the offshore Non-Deliverable Forward (NDF) market beyond RBI regulatory reach. How does the onshore/offshore segmentation affect liquidity and price discovery during stress?
Distinguish between turnover (total volume) and depth (resting orders at each price level). A market can have high turnover but poor depth if orders are concentrated at few levels.
Key Points to Cover
(a) Concentrated market-making (8–10 banks dominate INR interbank; when several withdraw, depth evaporates). Shallow order book — turnover concentrated in few large trades rather than a continuous stream. (b) Asymmetric RBI intervention creates asymmetric spreads — dealers widen quotes on the INR-appreciation side (fearing being short USD when RBI buys). The "RBI put" makes dealers more willing to provide INR liquidity on the depreciation side. (c) NDF market can "lead" onshore during stress — speculators short INR offshore (beyond RBI reach), pulling onshore rates with it. RBI has responded by intervening in NDF since ~2019–20.
In-Lecture Formative Quiz
4 Questions • 10 MinutesSelect the best answer for each question, then click Check Answers.
1. A dealer quotes EUR/USD = 1.0850 / 1.0854. A corporate customer wants to buy EUR and sell USD. At what rate will the transaction be executed?
2. From an Indian corporate treasurer's perspective, a quotation of INR 82.95/USD is a:
3. According to the BIS 2022 Triennial Survey, which statement about the global FX market is TRUE?
4. An Indian IT firm has USD 5M of export proceeds to convert to INR. Bank A: USD/INR 82.97/83.03. Bank B: USD/INR 82.94/83.00. Which bank offers the better rate, and what is the INR saving?
6. Numerical Problem Set — FX Quotations & Bid-Ask Mechanics
Solve the following problems. Show the formula, substitute values, and interpret. Problems 1–5 are guided; 6–8 for independent practice.
Direct ↔ Indirect: E_indirect = 1 / E_direct
Spread (absolute) = Ask − Bid
Spread (%) = (Ask − Bid) / Ask × 100
Midpoint = (Bid + Ask) / 2
Customer buys base → transacts at Ask; Customer sells base → transacts at Bid
Problem 1 — Bid-Ask Conversion: Dealer quotes USD/INR = 83.12 / 83.18. You are an Indian importer needing to pay USD 500,000. (a) At what rate do you transact? (b) How many INR do you pay? (c) What is the absolute and percentage spread?
Solution: (a) Importer buys USD → transacts at Ask = 83.18. (b) INR = 500,000 × 83.18 = INR 4,15,90,000. (c) Absolute spread = 83.18 − 83.12 = 0.06 (6 paise). % spread = 0.06/83.18 ≈ 0.072%.
Problem 2 — Direct to Indirect Quotation: USD/INR = 83.50. (a) Express in indirect terms from India's perspective. (b) If the rupee appreciates to 82.00/USD, what is the new indirect quote?
Solution: (a) INR/USD = 1/83.50 = USD 0.01198/INR. (b) At 82.00: INR/USD = 1/82.00 = USD 0.01220/INR. The indirect rate rises (0.01198 → 0.01220), confirming the rupee has appreciated — each rupee buys more dollars.
Problem 3 — Choosing Between Dealer Quotes: An exporter has EUR 2M to sell. Dealer X: EUR/USD 1.0810/1.0816. Dealer Y: EUR/USD 1.0812/1.0815. Which dealer gives the better rate, and what is the USD saving?
Solution: Exporter sells EUR → transacts at Bid. Dealer X bid = 1.0810. Dealer Y bid = 1.0812. Dealer Y is better (higher bid). USD received: X: 2M × 1.0810 = 2,162,000; Y: 2M × 1.0812 = 2,162,400. Saving = USD 400.
Problem 4 — European to American Terms: EUR/USD = 1.0920/1.0926. Express as American terms: USD/EUR (bid and ask).
Solution: USD/EUR bid = 1 / EUR/USD ask = 1/1.0926 = 0.9153. USD/EUR ask = 1 / EUR/USD bid = 1/1.0920 = 0.9158. Quote: USD/EUR = 0.9153 / 0.9158. Note: the bid and ask invert and swap positions when you invert a quote.
Problem 5 — Cross-Rate via USD: USD/INR = 83.00. USD/JPY = 150.00. Compute the JPY/INR cross rate (INR per JPY).
Solution: JPY/INR = (USD/INR) / (USD/JPY) = 83.00 / 150.00 = INR 0.5533/JPY. Alternatively: each JPY buys 0.5533 INR.
Problems 6–8 — Independent Practice
Problem 6: GBP/USD = 1.2650/1.2656. You are a UK importer needing to pay USD 100,000. How many GBP do you pay?
Problem 7: A dealer quotes USD/INR = 82.88/82.94. Compute: (a) the midpoint, (b) the INR spread per USD 1M round-trip (buy then sell immediately), (c) the percentage spread.
Problem 8 (Challenge): EUR/USD = 1.0850/56. USD/INR = 83.12/18. Compute the EUR/INR cross rate (bid and ask) — the rate at which an Indian firm can buy and sell EUR via the USD route.
7. Scenario Debate: FX Market Dynamics for Indian Firms
Four persona cards. Each group analyses FX market structure and quotation challenges.
GlobeTex exports cotton garments to European buyers, invoiced in EUR. Monthly export proceeds: EUR 3M. The firm converts EUR to INR monthly. GlobeTex's bank quotes EUR/INR with a spread of 12–15 paise. Rohit has noticed that the spread is wider at 10:30 AM IST (Asian morning, before European banks open) and tighter at 6:00 PM IST (during London/NY overlap). He is considering timing his monthly conversions to capture tighter spreads. He also wonders: can he bypass the bank and access the interbank market directly?
(a) How much annual INR could GlobeTex save by executing all conversions during the London/NY overlap (spread ~8 paise) vs. Asian morning (spread ~15 paise)? Assume EUR 3M/month, and the mid-rate is constant at INR 90/EUR. (b) Why can't a mid-sized Indian exporter access the interbank market directly? What structural features of the dealer-client market keep GlobeTex dependent on its bank? (c) Would it be economically feasible for GlobeTex to open an EEFC account, retain EUR earnings there, and convert only when rates are favourable?
Anjali runs the USD/INR trading book at Axis Bank. On a typical day, she quotes two-way prices to corporate clients, manages the bank's INR inventory, and lays off excess positions in the interbank market. At 11:45 AM, a large corporate client (an oil importer) requests a quote for USD 50M. At the same moment, Reuters flashes that the RBI is "seen buying USD at 82.80" — signalling that the RBI is preventing the rupee from strengthening below 82.80. The interbank market is long INR (dealers have been selling USD to the RBI). Anjali's current position: short USD 15M (she has sold more USD to clients than she has bought).
(a) What factors does Anjali consider when quoting a price for the USD 50M client trade — her current inventory, the RBI's presence, the interbank market position, and the potential price impact? (b) Should Anjali quote a wider spread than the standard 4–6 paise? If so, on which side — should she raise the bid, raise the ask, or both? (c) After executing the client trade (assuming the client buys USD), what does Anjali do to manage the resulting inventory position?
Priya's fintech startup, RuPay Global, is building a cross-border payment platform targeting Indian SMEs that export to 30+ countries and receive payments in 12+ currencies. The platform aggregates small FX conversions from hundreds of SMEs and executes them as a single large trade with partner banks, passing on wholesale spreads to the SMEs (retail bank spreads are 2–3x higher). RuPay Global uses the mid-market rate (Reuters FXFIX at 4:00 PM London) as its reference rate and adds a transparent markup (0.5%). The startup is growing rapidly but faces two challenges: (a) partner banks are reluctant to quote tight spreads for "non-standard" currency pairs (INR/NGN, INR/KES, INR/VND) that SMEs increasingly demand; (b) during the London/NY overlap, the 4:00 PM London fix is the most liquid window globally — but it's 9:30 PM IST, when most Indian SMEs are closed.
(a) For exotic pairs like INR/NGN, how does the lack of a direct market (most exotics trade via USD) affect the spread RuPay Global can offer? Trace the transaction chain: NGN → USD → INR and compute the total spread. (b) Should RuPay Global use the 4:00 PM London fix (tightest liquidity, but inconvenient timing for Indian clients) or an alternative reference rate during Indian hours? What are the trade-offs in terms of spread and customer experience?
Sterling Pharma exports generic drugs to 40+ countries. Its FX exposures are highly fragmented — revenue in USD, EUR, GBP, JPY, AUD, CAD, BRL, ZAR, and 8+ other EM currencies. Each month, the treasury receives 25–30 small FX conversions in exotic pairs. The firm currently uses its primary bank (SBI) for all conversions. Vivek suspects the bank is embedding wide spreads on the exotic pairs — the bank itself must lay off these positions in thin markets. He is evaluating three alternatives: (a) open a multi-currency account with a global bank (Citi, HSBC) and use their multi-bank FX platform (FXall); (b) net exotic-currency receipts pairwise where possible (e.g., offset BRL revenue against BRL API purchases from a Brazilian supplier); or (c) use currency futures on the NSE to hedge the major pairs (USD, EUR, GBP, JPY) and accept the exotic exposures as a cost of doing business.
(a) Compare the three alternatives in terms of spread cost, operational complexity, and risk reduction. (b) For exotic pairs with average monthly volumes under USD 50K, is hedging economically justified given the wide spreads, or should Sterling simply accept the currency risk? (c) How does the structure of the FX market — the central role of the USD as a vehicle currency — affect Sterling's ability to net exposures directly between, say, BRL and ZAR?

8. Fishbowl Debate: Should the INR Be More Freely Traded Offshore?
Debate Proposition
"This House believes that the RBI should liberalise offshore INR trading — permitting full deliverability of the INR in offshore centres (Singapore, London, Dubai) and dismantling the NDF market in favour of a unified global INR market — rather than maintaining the current onshore/offshore segmentation."
Position A: Liberalise Offshore INR Trading
- Unified market = deeper liquidity: Combining onshore and offshore INR trading into a single global market would create a deeper, more liquid INR market — reducing spreads for all participants. The current segmentation forces the same INR to trade at slightly different prices onshore and offshore, creating inefficiency.
- Internationalisation requires deliverability: If India wants the INR to become a genuinely international currency — used for trade invoicing and held as a reserve asset — it must be freely deliverable offshore. No currency has internationalised while remaining segmented. The RBI's recent initiatives (INR trade settlement, SRVAs) are half-measures unless offshore INR can be freely converted.
- The NDF market already exists — the RBI just cannot regulate it: The offshore INR market already exists — it's just conducted in NDFs beyond RBI oversight. Liberalisation would bring this activity under a unified regulatory framework rather than leaving it offshore and unregulated.
Position B: Maintain the Current Segmentation
- Full offshore deliverability = full Capital Account convertibility: If INR can be freely delivered offshore, speculators can build unlimited short-INR positions without RBI oversight. During a crisis, the RBI would lose its most powerful tool — the ability to restrict INR outflows. The 1997 Asian Crisis demonstrated the danger of premature Capital Account liberalisation.
- The NDF market serves a useful purpose — it's a safety valve: The NDF market allows foreign investors to hedge INR exposure without accessing the onshore market. This actually reduces pressure on the onshore INR market. Eliminating the NDF market would force all hedging onshore, potentially overwhelming the onshore market during stress.
- India's calibrated approach has worked: India's gradual, calibrated Capital Account liberalisation has avoided the crises that plagued countries that liberalised rapidly. The INR's internationalisation should continue — but at the pace determined by India's financial development, not by the demands of offshore financial centres.
Synthesis
"The onshore/offshore INR segmentation is a microcosm of the broader debate about financial globalisation versus national policy autonomy. The FX market structure you studied today — its participants, its layers, its trading sessions — is not a naturally occurring phenomenon. It is the product of deliberate regulatory choices, and those choices reflect a tension between the efficiency gains of integration and the stability gains of segmentation. The financial manager must understand both sides of this trade-off."
9. Key Concepts & Terminology — Week 9
Foreign Exchange (FX) Market
The global, decentralised, OTC marketplace for trading currencies — the largest financial market with daily turnover of USD 7.5 trillion (BIS 2022). Operates 24 hours a day across major centres: London, New York, Singapore, Hong Kong, Tokyo.
Over-the-Counter (OTC)
A market structure with no central exchange — trades are negotiated bilaterally between counterparties, by phone or electronically. Prices are not publicly displayed in a single order book; multiple dealers quote slightly different prices simultaneously.
Interdealer Market
The core of the FX market where the largest dealer banks trade with each other — directly or through electronic brokers (EBS, Reuters). This is the price-discovery engine; interdealer rates are the benchmark from which all other rates are derived.
BIS Triennial Survey
The most comprehensive survey of global FX market activity, conducted every three years by the Bank for International Settlements. Provides data on turnover by instrument, currency pair, counterparty, and trading centre. The April 2022 survey reported global daily turnover of USD 7.5 trillion.
Direct vs. Indirect Quotation
Direct: domestic currency per unit of foreign (INR 83/USD from India's perspective). Indirect: foreign currency per unit of domestic (USD 0.01205/INR). Direct = 1 / Indirect. The classification depends on which country you are in.
American vs. European Terms
Professional FX conventions: American terms = USD as base (USD/XXX). European terms = USD as quote (XXX/USD). EUR, GBP, AUD, NZD in European terms; all others in American terms. Universal — independent of the user's location.
Bid-Ask Spread
Bid = price at which dealer buys the base currency. Ask = price at which dealer sells. Spread = Ask − Bid. The transaction cost of the FX market. Determined by liquidity, volatility, transaction size, dealer inventory, and time of day.
Pip
"Price Interest Point" — the smallest standard unit of price movement in an FX quote. For most pairs: 0.0001 (e.g., EUR/USD moving from 1.0850 to 1.0851 = 1 pip). For JPY pairs: 0.01 (USD/JPY 150.00 to 150.01 = 1 pip).
Vehicle Currency
A currency used as an intermediary to facilitate trades between two other currencies. The USD is the dominant vehicle currency — on one side of 88% of all FX transactions. Most non-USD pairs (e.g., INR/JPY) are traded as INR/USD + USD/JPY rather than directly.
Non-Deliverable Forward (NDF)
A forward contract on a non-convertible or restricted currency, cash-settled in a convertible currency (typically USD) at the difference between the contracted rate and the prevailing onshore fixing rate. The INR NDF market operates offshore (Singapore, London, Dubai) beyond direct RBI regulatory reach.
WM/Reuters Fix (FXFIX)
A benchmark exchange rate calculated at 4:00 PM London time, based on actual trades and quotes in the interbank market during a 2.5-minute calculation window. The most widely used reference rate for corporate FX transactions globally — used to price cross-border payments, portfolio valuations, and index calculations.
Continuous Linked Settlement (CLS)
A global settlement system that eliminates "Herstatt risk" — the risk that one party to an FX trade delivers its currency but the counterparty fails before delivering the other currency. CLS settles both legs of an FX transaction simultaneously on a payment-versus-payment (PvP) basis.
Exit Ticket — Week 9
Complete each section. Estimated time: 7 minutes.
Describe the most important concept from this session — FX market structure, a participant type, a quotation convention, or the bid-ask mechanics.
Identify one concept that remains unclear. If you struggle with direct vs. indirect quotation or with bid-ask interpretation, articulate what confuses you.
EUR/USD = 1.0875/1.0881. (a) You need to pay a EUR 50,000 invoice — how many USD do you pay? (b) You receive EUR 20,000 from a client — how many USD do you receive? (c) What is the absolute and percentage spread?
As a future finance professional, you will interact with the FX market — converting export proceeds, paying foreign suppliers, or hedging currency risk. In 3–4 sentences, explain how understanding the FX market's structure (layers, participants, trading sessions, spreads) will make you a more effective financial manager.
