Derivatives houses have started buying protection on first-loss tranches of synthetic collateralized debt obligations they hold to offset risk they retained when issuing the senior tranches. Hedge funds have emerged as the main sellers of this protection. When first loss tranches of CDOs, which typically represent the riskiest 3% of a portfolio, were retained by dealers they were so out-of-the-money they did not have much mark-to-market volatility, noted Frank Iacono, senior v.p. in structured credit products at Lehman Brothers in New York. Record spread tightening in credit-default swaps over the past year, however, has moved the positions in the money and in turn made them vulnerable to spread volatility and changes in correlation, he said.
