Consider deposits in different currencies, but also consider the future changes in the proportion of different currencies. For RMB and Australian dollar, there is exchange rate risk for China people to hold Australian dollar.

Lowering interest rates usually leads to the devaluation of the country's currency.

On the other hand, because the whole world is cutting interest rates, so are China and Australia. It is precisely because the interest rate of RMB is relatively low, so there is less room for interest rate cuts and fewer factors for depreciation.

Give another recent example. In the first half of 2008, the interest rate of the Australian dollar was above 6% (the China and Hongkong Bank has 6.5% semi-annual time deposits). On the surface, Australian dollar deposits are more cost-effective than RMB deposits. But in fact, since the second half of 2008, the Australian dollar has depreciated by more than 20% against the RMB, so it is not worth the candle.
