Brazil's second currency market intervention in two days could create a dangerous target level for speculators to attack, analysts said yesterday.

Brazil's central bank stepped in to sell dollars on Tuesday for the first time since the embattled real was floated just over a month ago, hauling the currency back to around two to the dollar after it slid to 2.07.

A second intervention yesterday held the real at a similar level after it slipped to 2.02, surprising some analysts who had seen the previous day's move as a one-off.
