The Canadian dollar is seen as a commodity currency and metal prices have been going up across the board, commodity prices are up.

With the commodity prices easing, especially oil and natural gas, the expectation is that the Canadian dollar would actually come down somewhat.

The rand, as a commodity-based currency, should benefit from the surge in precious metals' prices as it has in recent times.

There were probably industrial prices that were helping support the Canadian dollar and also some of the data that we'll get at the end of the week could be on the strong side.

If the Fed ceases hiking, against the backdrop of still rising commodity prices, then the Australian dollar will have few reasons for resisting any topside advances.

The Canadian dollar is relentless.
