The Bank of Portugal unveiled a 4.9 billion-euro ($6.6 billion) plan to rescue Banco Espirito Santo. The plan will split the bank into two parts -- a good bank, which will receive the capital injection, and a bad bank, which will be wound down. The Deal correspondent Renee Cordes weighs in on the rescue plan and whether the healthy bank will appeal to investors. Cordes says there are still a lot of unanswered questions about how the plan will work out, and she predicts investors will be hesitant to buy in. She also reveals what this rescue means for Portugal and the euro zone going forward, as its resilience to another banking crisis is tested.
