The Australian and Canadian dollars increased on Tuesday, helped by a surge in oil prices to five-month highs that boosted most commodity-linked currencies.

Oil prices have rallied on anticipations that worldwide supplies would tighten up because of fighting in Libya, OPEC-led cuts and U.S. sanctions versus Iran and Venezuela, while energy prices slid marginally on Tuesday.

The Australian dollar increased 0.3 percent to $0.7151 after previous moving a three-week high.

Canada's currency firmed to C$1.3293, its strongest since March 21.

Societe Generale, analyst noted that although oil exporter currencies including the Russian rouble, Mexican peso, Canadian dollar and Norwegian crown were all doing well, important importer country currencies like the Turkish lira, Korean won and Indian rupee had suffered.
