Yields on peripheral bonds dipped, while European stocks and the euro held their breath on Wednesday as fractious parties in the Greek parliament prepared to vote on EU-prescribed austerity measures needed to unlock a third bailout. Tsipras defended the deal, saying it was better than the alternative of being forced out of the euro zone. The parliamentary vote is seen as the key hurdle to a final agreement for the bailout, which could end — at least temporarily — months of increased uncertainty, volatility and frequent risk aversion in financial markets.
