Commerzbank analyst Simon Quijano-Evans recently analysed credit ratings for emerging market countries and concluded that there is a strong tendency to "under-rate" emerging economies - that is they are generally rated lower than developed market "equals" that have similar profiles of debt, investment or reform. The reason, according to Quijano-Evans, is that ratings assessments tend to be "blurred by political risk which is difficult to quantify and is usually higher in the developing world compared with richer peers.
As world leaders gather this week for the annual International Monetary Fund and World Bank autumn meetings, Ebola will be top on the list of priorities.

Almost 3,000 West Africans have died from the current outbreak of Ebola virus, and on Tuesday, the U.S. Centers for Disease Control and Prevention warned that by January between 550,000 and 1.4 million people could be infected if nothing is done.
The Ebola outbreak continues to spread in Guinea, Liberia and Sierra Leone, the countries hardest hit by the disease. More than 1,000 people have now died from the virus. The Centers for Disease Control and Prevention has issued its highest-level alert for a response to the Ebola crisis. The World Health Organization has declared the outbreak a Public Health Emergency of International Concern. The disease is intensifying in West Africa, but the epidemic poses minimal risk to Americans. So why are we so afraid?
