Los derivados y la crisis

Mucho se ha escrito en las ultimas semanas sobre el uso y abuso de los "derivados" como una de las causas de esta crisis. Y naturalmente varios analistas y expertos han salido a pedir que sean fuertemente regulados.

Sin duda, los derivados de credito, una forma de seguros, conocidos como "Credit Default Swap" o CDS (por sus siglas en ingles), han sido uno de los principales elementos de esta crisis. Para un excelente resumen del tema, ver esta pagina.

Sin embargo, como lo explica este articulo, la mayoria de estos derivados de credito, excepto los relacionados con las hipotecas han funcionado bien y su rol como "gestionadores de riesgo" no deberia ignorarse:

"The amount of blame laid at the feet of the derivatives market never ceases to amaze me. True, the sheer size of the derivatives market, and the fact that it grew faster than regulators could handle, raise legitimate concerns. But financial products are not solely to blame for the current situation (severe financial crises occur without them). Further, the markets for most financial derivatives (excepting mortgage-backed CDOs) are not in serious peril. Felix Salmon wrote an eloquent defence of how the Credit Default Swap (CDS) market has functioned and continues to function quite well.
Products like CDS provide invaluable transparency for the debt market. The problem, as both Mr Salmon and Mr Merton point out, is that these derivatives hedge risk. This makes investors feel safer, and just as people wearing seat belts drive faster and those with four-wheel drive become more likely to drive in the snow, a financial safety net encourages some investors to take on more risk than might otherwise be their preference.
That's not necessarily a bad thing. It encouraged people to invest in developing countries, which gave those countries the capital necessary to build infrastructure and expand markets. Which brought many people out of poverty. But it also meant some foolish and foolishly large investments were made. Blaming the financial derivatives for the crisis is like blaming the seat belt or four-wheel drive for the accident. Should we limit automotive safety innovations, because they encourage risky driving?"


El problema de los derivados en esta crisis esta basicamente circunscrito a los relacionados con hipotecas. No deberia olvidarse que esta crisis se origina por una caida de precios en el sector inmobiliario.

No es esta una crisis de derivados. Es una crisis del sector inmobiliario, altamante dependiente de las tasas de interes, que se extendio al sector financiero y luego al sector real.
