Foreign Exchange and Eurocurrency Markets
Week 4 covers FX market mechanics, quotation and cross-rates, and the FX risk types banks and clients face (transaction, translation, economic), then introduces Eurocurrency / offshore currency markets — deposits held outside the currency's home jurisdiction — why they exist and how they price. It links FX and interest-rate exposure to hedging products (forwards, swaps, options) and to the organisational forms for cross-border banking. It is examined as a cross-rate or parity calculation plus a short conceptual answer on FX risk or offshore markets.
What this chapter covers
- 01FX quotation: direct vs indirect, base/quote currency, bid–ask spread; spot (T+2) vs forward vs FX swap
- 02Cross-rates: deriving a third-currency rate from two quotes
- 03Covered interest-rate parity (CIP): F/S = (1 + i_domestic) / (1 + i_foreign) — arbitrage-enforced forward premium/discount
- 04Uncovered interest parity (UIP), purchasing power parity (PPP) and the international Fisher effect
- 05FX risk types: transaction (contracted cash flows), translation (accounting), economic (operating) exposure
- 06Eurocurrency / offshore markets: deposits in a currency outside its home jurisdiction (e.g. Eurodollars); why they grew (regulatory/tax arbitrage)
- 07Hedging instruments: forwards, futures, options, currency swaps, money-market hedge
- 08Organisational forms for cross-border banking (correspondent → rep office → agency → branch → subsidiary) and US vehicles (Edge Act, IBF)
Deriving an AUD/JPY cross-rate
- +1Write each quote with explicit units. Quote 1: S₁ = 0.6600 USD per AUD. Quote 2: S₂ = 150.0 JPY per USD. The target is JPY per AUD.
- +1Chain the quotes so the shared currency (USD) cancels: (JPY per AUD) = (JPY per USD) × (USD per AUD) = 150.0 × 0.6600.
- +1Compute: 150.0 × 0.6600 = 99.0. So the cross-rate is 99.0 JPY per AUD.
- +1Sanity-check the magnitude: 1 AUD ≈ 0.66 USD and each USD is worth 150 JPY, so 1 AUD should be worth a bit under 150 JPY — 99 JPY is consistent. (If you had divided instead of multiplied you would get 227, which fails the check.)
Key terms
- Cross-rate
- An exchange rate between two currencies derived from each one's rate against a common third currency (usually the US dollar); computed by chaining the two quotes so the shared currency cancels.
- Covered interest-rate parity (CIP)
- The arbitrage condition F/S = (1 + i_domestic)/(1 + i_foreign), so the forward premium or discount on a currency equals the interest-rate differential; deviations are closed by covered arbitrage.
- Transaction exposure
- FX risk on known, contracted future cash flows in a foreign currency (e.g. a receivable due in three months); the most directly hedgeable of the three exposures, using forwards, options or a money-market hedge.
- Translation exposure
- Accounting FX risk from restating a foreign subsidiary's financial statements into the parent's reporting currency; it affects reported equity and earnings rather than cash flows directly.
- Eurocurrency market
- The offshore market in bank deposits and loans denominated in a currency other than that of the country where the bank is located (e.g. Eurodollars = US-dollar deposits held outside the US); it grew largely to escape domestic tax and regulation.
- FX swap
- A simultaneous spot purchase and forward sale (or vice versa) of a currency, used to manage or roll currency exposure; distinct from a currency swap, which also exchanges interest streams over a longer horizon.
Foreign Exchange and Eurocurrency Markets FAQ
What is the difference between transaction, translation and economic FX exposure?
Transaction exposure is on known, contracted future cash flows in a foreign currency and is the most directly hedgeable. Translation exposure is an accounting effect from restating a foreign subsidiary's statements into the home currency — it hits reported equity and earnings, not cash directly. Economic (operating) exposure is the change in the present value of future cash flows as FX moves alter a firm's competitiveness, and is the hardest to hedge because it is strategic.
How do I compute a cross-rate?
Write each currency's rate against the common currency (usually USD) with explicit units, then chain the two quotes so the shared currency cancels — multiplying or dividing as the units require. For example, JPY per AUD = (JPY per USD) × (USD per AUD). Always finish with a magnitude sanity-check to catch an accidental division where you needed a multiplication.
What is the Eurocurrency market and why did it grow?
It is the offshore market in bank deposits and loans denominated in a currency outside its home jurisdiction — Eurodollars being US-dollar deposits held outside the US. It grew because domestic tax and regulation (reserve requirements, rate ceilings) made onshore intermediation costlier, so banks and depositors moved the business offshore — a form of regulatory arbitrage that also aided banks' asset-liability management.
Can AI help me with the FX topic?
Yes, as a study aid. Sia can walk you through cross-rate derivations, covered interest-rate parity and the other parity conditions, the three FX exposures and how to hedge them, and the rationale for Eurocurrency markets. It teaches the method and checks your unit work; it does not do your graded UNSW assessment, and the academic-integrity policy applies.
Exam move
Split this chapter into a calculation half and a concept half. For calculations, drill cross-rates until unit-cancellation is automatic (write JPY per USD, USD per AUD, cancel USD), and be able to state covered interest-rate parity F/S = (1 + i_domestic)/(1 + i_foreign) and explain the forward premium/discount as the interest-rate differential. Always attach units and a magnitude sanity-check. For concepts, be able to define and contrast the three FX exposures (transaction, translation, economic) and say which hedging instruments fit each, and to explain the Eurocurrency market as offshore currency intermediation driven by regulatory and tax arbitrage. Keep the organisational-forms ladder (correspondent → rep office → agency → branch → subsidiary) from Chapter 1 handy, since it resurfaces here with the US-specific Edge Act and IBF vehicles. Ask Sia to set fresh quote pairs and a short FX-risk scenario; confirm the calculator policy and assessment details on the FINS3650 course outline.
