Regulators to probe euro trades

The regulatory fall-out from the Greek debt crisis grew on Wednesday as EU and US authorities said they would probe trades in the euro and the market in sovereign credit default swaps. European Commission officials said they would use a meeting as early as Thursday with banks and regulators to discuss regulation of trading in sovereign CDS, which have become politically contentious amid Greeceā€™s financial crisis. The US justice department said it was also examining hedge fund trades against the euro.
