1248 GMT - The rise in energy prices stemming from the Iran war poses a headwind to eurozone growth and the euro, MUFG Bank's Derek Halpenny says in a note. Europe faces a terms of trade hit from a further surge in energy prices, particularly natural gas prices, he says. Europe delayed winter gas purchases after the onset of the war and this appears to be backfiring, he says. Drought across Europe is also affecting food production and boosting energy demand. MUFG estimates that the euro is currently about 2.5%-3.0% overvalued versus the dollar. The euro could underperform if the above factors start to impact sentiment and economic activity, Halpenny says. The euro last trades steady at $1.1574.
