Evaluación de los márgenes requeridos en un mercado de derivados de energía eléctrica


  • Javier Orlando Pantoja Robayo
  • Kelly Maradey Angarita
  • Alfredo Trespalacios Carrasquilla


Los mercados de contratos futuros tienen como fortaleza la eliminación del riesgo de contraparte, para esto es importante el nivel de garantías que las cámaras de riesgo exigen a los participantes del mercado -- Estas garantías deben cubrir las variaciones extremas del precio del producto, pero no deben ser excesivas porque reducen la cantidad de eventuales participantes en el mercado -- En este trabajo se propone una metodología alternativa para la estimación de las garantías del mercado de futuros en energía eléctrica, como caso de estudio se presenta el mercado colombiano -- Se realiza simulación de Montecarlo para evaluar las variaciones diarias que puede tener el precio de los futuros y se estiman medidas de riesgo con diferentes escenarios de Nino, días de tenencia y vencimientos -- Se encuentra que la nueva metodología propuesta modifica sustancialmente los niveles de garantía, frente a la metodología actual de cálculo, adicionalmente, se enuncian los factores que alteran su definición
