Dual Currency Investment


An alternative to traditional term deposits - Optimising your investment

If you would like to take advantage of foreign exchange movements and potentially earn a higher rate of interest when compared to a conventional term deposit, you may wish to consider investing in a Dual Currency Investment.

What is a Dual Currency Investment?

  • A Dual Currency Investment (DCI) is a foreign exchange-linked term deposit. The principal of the DCI is paid on its maturity date in either the deposit currency or the alternative currency, depending on the exchange rate movements of the two currencies and their levels at or about the payment currency fixing time. Your Banking Partner will provide you with details of the payment currency fixing time.
  • Interest on the DCI will always be paid on the maturity date in the deposit currency.

Your currency choices

You can choose a currency pair from a range of currencies:

 Singapore Dollar (SGD)

Hong Kong Dollar (HKD)

 US Dollar (USD)

 Australian Dollar (AUD)

New Zealand (NZD)

 Great British Pound (GBP)


 Canadian Dollar (CAD)

Japanese Yen (JPY)

 Swiss Franc (CHF)

Other currencies are available upon request.

Maximise your potential returns

  • Placing your DCI is easy! The minimum principal amount is USD 50,000 (or its equivalent in other currencies), or SGD 250,000 when investing in SGD. You can select from a range of investment periods from 7 days to 12 months. Based on your selection of investment period and currency pair, NAB will quote an applicable interest rate and pre-determined exchange rate.

How does it work?

Alternative Currency
Principal Amount
Investment Period
30 days
Pre-determined Exchange Rate
AUD/USD 0.7780^
Interest Rate

Traditional Term Deposit Interest

^ AUD/USD refers to 1 Australian Dollar to the equivalent amount of US Dollar.

The illustration below shows the possible return in three different scenarios:

Scenario 1:

Invest in Dual Currency Investment

If Spot Rate is equal to or above the Pre-determined Exchange Rate at the Payment Currency Fixing Time

Settlement Amount
= Principal Amount + (Principal Amount x Interest Rate x Investment Period / Calendar Year Days)
= USD50,000 + (USD50,000 x 10% x 30 / 360)
= USD50,000 + USD416.67
= USD50,416.67

= USD50,416.67 - USD50,000
= USD416.67 (gain)
Scenario 2:

Invest in Dual Currency Investment

The Spot Rate on the Maturity Date is below the Pre-determined Exchange Rate at the Payment Currency Fixing Time.

Settlement Amount
= Principal Amount / Pre-determined Exchange Rate + (Principal Amount x Interest Rate x Investment Period / Calendar Year Days)
= USD50,000 / 0.7780 + (USD50,000 x 10% x 30 / 360)
= AUD64,267.35 + USD416.67

If the AUD amount is converted back to USD immediately at the market Exchange Rate (0.6500 in this scenario) on the maturity date, a loss on Principal Amount will be incurred.

= USD50,000 - AUD64,267.35 x 0.6500
= USD50,000 - USD 41,773.78
= USD 8,226.22 (loss)
Scenario 3:

Start a fixed deposit

Principal Amount + Interest
= USD50,000 + (USD50,000 x 3.00% x 30 / 360)
= USD50,000 + USD125
= USD50,125

= USD50,125 – USD50,000
= USD 125(gain)
