Published by Mark Smith-HalvorsenThe Australian dollar was trading at a four-month high against the greenback in global forex trading this morning, supported by stronger than expected jobs data.After breaking resistance at $0.92, the currency traded as high as $0.9237 in Asian markets and was also climbing against the euro.However, the Aussie made little progress against the yen as the Japanese currency flirted with fresh 15-year highs against the dollar.Speaking to Reuters, Koichi Yoshikawa, head of FX trading at BNP Paribas, said the Aussie has found support among traders who anticipate that the Reserve Bank of Australia will raise the cash rate once again."The direction of monetary policy is completely the opposite between the United States and countries like Australia and Canada. So currencies like the Aussie and the Canadian dollar will tend to be favoured," he said.The central bank last raised the cash rate in May, with a 25 basis point hike bringing the target to 4.5 per cent.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site.
