LONDON, Nov 25 (Reuters) - The dollar extended losses on Wednesday, hitting a 15-month low against the euro, on views U.S. rates would stay low and as Russia said it would diversify currency reserves.
The euro rose to $1.5096 EUR=, its highest since early August 2008, according to Reuters data.
The Swiss franc rose to 0.9994 franc against the dollar CHF=, briefly breaking parity for the first time since April 2008.
Russia's central bank said on Wednesday it was preparing to invest some of its foreign exchange reserves in Canadian dollars CAD=D4 in order to diversify its currency portfolio. (Reporting by Naomi Tajitsu and Tamawa Desai)
