FXstreet.com (Barcelona) - The hefty AUD/USD, trading above 1.00 for most of the past 2 year, continues to put pressure for Australian exporters, making them less competitive internationally, while local importers are also being hurt, since getting stuff from overseas is much cheaper these days. One of the sector being potentially damaged by the high levels of the Aussie, is the mining. Amid this scenario, Fitch rating agency released the following statement:

"The Australian dollar has an increasingly important role as a reserve currency. This could remove the smoothing impact that the currency's historically strong correlation with commodity prices has had on the reported results of Australian mining companies, Fitch Ratings says."

"The strong correlation between the Australian dollar and price of commodities such as iron ore and coal smoothed the results of mining companies and was of particular benefit when the performance of both was weak. Lower US dollar revenues from depressed commodity prices were partially offset by the translation of Australian dollar costs to the company's US dollar-denominated profit statement at a lower rate."

"However, Australia's strong economic performance in recent years has increased the Australian dollar's popularity as a reserve currency to such an extent that the International Monetary Fund is considering whether to include it in the fund's regular report on foreign exchange holdings. Relatively high interest rates compared with other developed markets also continue to attract investors."

This demand for the Australian dollar helped the currency remain strong in 2012 despite a drop in commodity prices. This is likely to continue to support the currency in the near term and will add to the pressure we expect mining companies to face from a combination of cost inflation and stagnant commodity prices in 2013.

"It is unclear if this decoupling will become permanent as economic conditions in other developed markets improve. But if it does continue, it will increase volatility in mining companies' reported results as factors other than commodity prices have a bigger influence on the currency. The impact will be greatest on companies whose operations and assets are concentrated in Australia and use the US dollar as the functional currency, such as Fortescue Metals Group Limited. For the global mining companies like BHP Billiton and Rio Tinto, the impact will be mitigated by conservative financial and leverage profiles and by their commodity and geographic diversification."
