Exxon Valdez led to the creation of credit default swaps.
In the case of Baker v. Exxon, an Anchorage jury awarded $287 million for actual damages and $5 billion for punitive damages. The punitive damages amount was equal to a single year's profit by Exxon at that time.
To protect itself in case the judgment was affirmed, Exxon obtained a $4.8 billion credit line from J.P. Morgan & Co.
This in turn gave J.P. Morgan the opportunity to create the first modern credit default swap in 1994, so that J.P. Morgan would not have to hold so much money in reserve (8% of the loan under Basel I) against the risk of Exxon's default.
