What it means
The bond divides its cash flows by currency, so an investor can receive periodic coupons in one currency but a final principal payment in another, and converting both into the investor's reporting currency can change the economic return even when every contractual payment is made. A 2018 IFRS Interpretations Committee staff paper considers a bond with principal denominated in one currency and fixed coupons in another and examines the contractual-cash-flow classification question under IFRS 9.
A staff discussion paper is not permission to apply one accounting result to every differently structured bond. Coupon currency determines the cash received during the life of the instrument, so an investor needing another currency must convert those payments or maintain them as foreign cash, and conversion costs and exchange-rate changes can affect the usable amount.
Principal currency determines the redemption exposure, which can be larger than a single coupon because the principal amount is repaid together at maturity, so a stable coupon stream does not ensure a stable home-currency redemption value. The exchange convention must be identified, since some arrangements specify amounts directly in each currency while others use particular conversion rates or formulas, and the exchange rate at purchase should not be assumed to control every later payment.
An issuer can have a business reason for using two currencies, because its revenues, assets or financing needs may be split across markets, but that reason does not establish that an investor has a matching hedge or that the issuer's exposure disappears. The investor's own obligations matter too, since coupons in one currency might match operating costs while principal in another may not match future spending, so currency matching should be assessed payment by payment rather than from the bond's name.
A high coupon can compensate for risks or less favourable terms, and the complete cash-flow schedule, credit quality, liquidity and currency exposure should be compared, because comparing only coupon percentages between currencies can misstate the expected economics. Credit risk remains separate, as a favourable exchange movement does not protect against issuer default, while an issuer can pay every promised amount and the investor still suffers a loss after converting the money.
Hedging requires care because there are several payment dates, so a single currency hedge may not cover all coupons and principal and its costs, collateral needs and maturity should be included in the investment analysis. Early sale adds valuation uncertainty, since market rates, exchange rates and credit spreads affect the price before maturity and redemption in a specified currency does not provide a fixed early-exit price.
For a non-finance manager, draw a schedule showing each date, amount and currency. Translate it into the currency used for the business's decisions under several exchange scenarios.
Keep contractual payment, converted value and accounting treatment as separate questions.
In practice
Real-world examples.
Example
A company invests in a bond paying euro coupons and dollar principal. Treasury checks whether each currency matches its future needs rather than calling the whole instrument a euro investment.
Example
An investor receives every coupon on time but sees the home-currency value of the principal decline as exchange rates move. The review separates currency loss from credit performance.
Example
An issuer proposes a higher-coupon dual currency bond. The buyer compares the full converted cash flows and hedge costs with a plain bond before deciding whether the extra coupon compensates for the risks.
Formula
Calculation
Home-currency value of redemption = foreign principal x home-currency units per foreign unit. Coupons, fees, purchase price and hedging are excluded from this first isolated principal example.
Worked example 1. If principal is 100,000 foreign units and the conversion rate falls from 1.20 to 1.05 home units per foreign unit, redemption value falls from 100,000 x 1.20 = 120,000 home units to 100,000 x 1.05 = 105,000 home units, a drop of 15,000.
Worked example 2, including coupons. An investor with dollars as the home currency pays 100,000 foreign units at the 1.20 rate, so the purchase cost is $120,000. The bond pays $3,000 of coupons a year in dollars for 5 years, a total of 5 x $3,000 = $15,000, and returns 100,000 foreign units at maturity when the rate is 1.05, which converts to $105,000. Total cash received is $15,000 + $105,000 = $120,000, equal to the $120,000 cost, so the coupons were entirely offset by the $15,000 currency loss and the investor earned nothing in dollars even though every payment was made in full.Case study
Seen in the real world.
Fictional case: A distributor buys a dual currency bond to fund a planned equipment purchase. Coupons match its routine expenses, but principal is repayable in another currency. A later exchange movement leaves the expected equipment budget short. Treasury changes its review to test coupon and redemption exposures separately and stops treating a contractual principal amount as a fixed value in the spending currency.
Treasury also asks whether a forward contract on the principal would have helped, and finds that the hedge would have fixed the home-currency value but at a cost that reduced the extra coupon. The board decides that future purchases of similar bonds must show the converted cash flows under at least three exchange scenarios, plus the hedge cost, before approval. The company keeps its equipment budget in the currency of the supplier contract.
Watch out
Common mistakes.
- Treating the bond as if all payments use one currency.
- Comparing coupon percentages without exchange and hedging effects.
- Assuming full contractual repayment prevents a home-currency loss.
Questions
People also ask.
Is it the same as a foreign-currency bond?
No. A conventional foreign-currency bond can use one currency for both coupons and principal.
Can exchange risk affect only principal?
No. Each payment should be checked against the investor's reporting currency.
Does a higher coupon remove the risk?
No. It must be assessed with credit, currency and contractual terms.
