Analysts are predicting a reinsurance industry collapse following the plane crashes, hi-jackings and destroyed buildings in the US.
One analyst said, "This is going to cause a reinsurance meltdown with losses in the billions."
Stock prices of the top reinsurance companies reacted dramatically to the first plane attack on the World Trade Centre. Zurich Group fell 10%, Swiss Re lost 15% and Munich Re dropped 14.5% immediately.
There was a further large drop in stocks as the World Trade Centre's towers collapsed.
