In appearance on Bloomberg TV, Citi credit strategist Michael Hampden-Turner discussed the advantages of a maturity extension of Greece's troubled debt over a restructuring. "The risk is that if you take a big haircut to Greek bonds, you've solved one problem, but you create another," Hampden-Turner said. "...You get a sort of contagion effect not only to sovereigns, but also to financials that might be affected as well."
