The Swiss franc hit record highs against the dollar, euro and sterling today as the safe-haven currency continued to benefit from economic uncertainties heading into the New Year, traders said. The Australian dollar also leapt to a record against the dollar thanks to rallying commodity prices. Markets were awaiting the release later today of US jobless claims and homes sales data. Ahead of the figures, the euro slumped to an all-time low of 1.2396 Swiss francs. The dollar weakened to 0.9374 francs and the pound to 1.4525 - also record low points against the Swiss currency. Meanwhile, the Australian dollar leapt to a record high of $1.0197. The resources-based Aussie has traded near or above parity with the greenback since first breaking through on October 15, having surged about 20% since June as Australia experiences a robust mining boom.
