Tips on Overnight Interest
How is a High Overnight Interest Rate Generated?
- As of 30th June 2025, wide interest rate differences still remain:
- Higher yielding currencies include USD: 4.50%, GBP: 4.25%, EUR: 2.00%, and AUD: 3.85%
- Lower yielding currencies include JPY: 0.5%, and CHF: 0%
- The USD/JPY and the USD/CHF are the two currency pairs with the largest interest rate differentials among major currency pairs.
- Buying USD/JPY is conceptually equivalent to borrowing Japanese yen at a low interest rate and then buying U.S. dollars with a higher yield, thus profiting from the interest rate differential. In recent years, the interest rate gap between the U.S. and Japan has widened significantly, further enhancing the appeal of such carry trades. Buying USD/CHF follows the same principle, representing a typical strategy of financing in a low-interest-rate currency and investing in high-yield assets.
How to Earn Overnight Interests?
- Overnight interests will be generated by holding positions overnight at 6:00 a.m. Hong Kong Time (New York Winter Time) or 5 a.m. Hong Kong Time (New York Summer Time), and will be reflected in the account balance automatically (more details)
For open positions held overnight through Wednesday's Trading Close, "3-Day" overnight interest will be realized in order to account for the settlement of trades through the weekend period. - You may earn interest by buying a relatively high interest rate currency. Conversely, you will need to pay interest for holding a relatively low interest rate currency
