Let's go back to the financial crisis and the practices that brought this country to its knees. Banks developed a fancy scheme whereby they absolved themselves of all risk from the loans they made. They simply wrapped them up in a bundle and sold them to someone else. What they were doing is essentially packaging and reselling "junk."

When the news of how bad things were became known, the markets froze and collapsed. No one knew who had which securities, and if they did, they didn't know their true value.

Even though we can anticipate billions of dollars in claims there still are buying opportunites.

Do you have any interest in insurance companies amidst the turmoil, disaster and current crises in Japan?

Perhaps you think this is even a poorer idea than catching that proverbial falling knife we are always hearing about when stock prices are collapsing.

On the other hand, perhaps the burden will be spread around the globe to reinsurer's such that none is struck too hard and this is a buying opportunity.

It is also likely those that never saw the need for insurance have been awakened and demand will increase.

Catastrophe bond capacity is maturing, and not much of it is coming back. In the first quarter, $1.8 billion in cat bond risk capital matured, and only $508 million returned in the form of new issuances, according to Thomson Reuters. This quarter, $2.77 billion is maturing, and the absence of first-time issuers makes it unlikely that the market will replace it all. More than a billion of it was from State Farm's Merna Re transaction. The successor to it has already been issued, cleverly named Merna Re II, at only a fraction of the previous bond.
