GOLD AT NEW RECORD
In currency markets the euro EUR= hit $1.4249, its highest since November, boosted by expectations the European Central Bank will raise interest rates next month, which prompted demand from longer-term "real money" investors.
"Euro/dollar is supported after (ECB President Jean-Claude) Trichet continued to signal a rate hike in April," said Mic Ingenuus, currency strategist at Nordea in Copenhagen.
