Benchmark oil for June delivery was down $1.22 to $92.76 a barrel, the lowest since November, at midday Singapore time in electronic trading on the New York Mercantile Exchange.

Investor concern over economic growth Crude has plunged more than 12% from $106 earlier this month amid investor concern global economic growth will slow more than previously expected this year. US crude inventories are at a 22-year high amid weak demand and growing production. Greece announced on Tuesday it would hold new elections, probably next month, after politicians failed to form a government after a vote earlier this month. Traders fear Greece may drop the euro currency, which could trigger a loss of confidence in other debt-burdened European countries such as Spain and Italy. Europe is already teetering near recession this year, and further political turmoil could hurt economic activity and demand for crude. \"The chances that Greece will leave the euro-zone sooner rather than later are growing,\" Capital Economics said in a report. \"The key question remains whether the policymakers can prevent contagion effects from prompting a bigger and much more damaging breakup of the currency union.\"
